    Visual working memory (VWM) plays a crucial role in various higher cognitive activities such as problem-solving, learning, and decision-making. The function of VWM extends beyond mere information storage; it also requires the preservation of memory fidelity to ensure the smooth execution of various cognitive activities. State-based models of visual working memory propose a hierarchical structure of memory storage, consisting of both online and offline states. Previous studies have evidenced that memory representations in these two distinct storage states exhibit some resilience to irrelevant distractor and time decay. However, while the properties of memory representations in these two states have been explored independently, it was still unclear whether online and offline memory representations possess comparable resistance to distractor and time decay when exposing to identical cognitive processing.
    Thus, this study aimed to compare the robustness of memory representations in the online and offline states, with the goal of determining which storage state had superior resilience. To achieve this, we adopted a sequential presentation memory task, which facilitated the co-existence of both online and offline representations by effectively separating representational storage states. The primary experimental variables were the presence of distractors (Experiment 1) and retention duration (Experiment 2) during memory maintenance involving both states. This design allowed us to examine the effects of these factors on memory representations in the two storage states. A total sample of 115 was recruited in four behavioral experiments. Experiments 1a/1b assessed the effect of distractor on memory representations in the online and offline states, while Experiments 2a/2b examined the effect of time decay. We predicted that, if memory representations in the two states exhibited equal robustness, memory performance in both storage states would remain largely unaffected by the presence of distractors or extended retention duration. Whereas if the representational robustness was weaker in one storage state, then either the presentation of distractor or prolonged retention would result in a significant memory decline in that state.
    The results of Experiment 1 collectively showed that when distractor was unexpectedly presented, online memory performance was significantly impaired, while no impairment occurred to offline memory. Experiment 2 jointly revealed that as the retention duration increased from 1s to 3s, significant impairment occurred to online memory only, while offline memory performance was clearly unaffected. These findings indicated that memory representations in the online and offline states differ in their robustness within the identical cognitive processing. Specifically, offline memory had superior resilience compared to the online when it came to resisting both unrelated distractor and time decay.
    In summary, during working memory maintenance employing both online and offline storage states, offline memory exhibits a robustness superiority in resisting interference from distractors and temporal decay compared to online memory. These findings contribute to a deeper understanding of multi-state storage mechanisms in working memory, and suggest new directions for future memory research.

    How magnitude and ordinal cues of stimuli influence the SNARC effect
    WANG Qiangqiang, WU Yanwen, SHI Wendian, YOU Xuqun
    2025, 57 (5):  749-761.  doi: 10.3724/SP.J.1041.2025.0749

    Dehaene et al. (1993) found that participants typically associated small numbers with pressing the left key and large numbers with pressing the right key when they classified the given numbers by pressing the left or right key as correctly and quickly as possible. They defined this phenomenon as the spatial-numerical association of the response code (SNARC) effect. After Dehaene and his collaborators captured the SNARC effect in Arabic numerals processing, subsequent studies further confirmed the existence of the SNARC effect in other types of symbolic numbers and non-symbolic numbers and the stimuli with magnitude information. On the cause of the SNARC effect, various theories provide explanations. For example, the ATOM (a theory of magnitude) model suggests that in the human brain, there is a generalized magnitude system where various symbolic and non-symbolic numbers and stimuli with magnitude information are processed to result in the SNARC effect. Ordinality theory holds that the processing of ordinality information from stimuli including numbers leads to the SNARC effect. Magnitude-ordinality double action theory states that both the magnitude and ordinality of stimuli contribute to the SNARC effect. These theories have deepened our understanding of the mechanism of the SNARC effect, but contradictions exist among these theories on the following basic theoretical questions. First, is it the magnitude of the numbers or the ordinal cues of the numbers that causes the SNARC effect in the processing of numbers? Second, how do the magnitude and ordinal cues of the numbers influence the SNARC effect? A critical reason why the above two theoretical questions could not be solved is that the magnitude and ordinal cues of the experimental stimuli are not well separated in the previous studies.
    Therefore, this study used a new stimulus in which the magnitude and ordinal cues were both contained and could be well separated, aiming to systematically investigate the magnitude and ordinal cues of the numbers that led to the SNARC effect and how the magnitude and ordinal cues of the numbers influenced the SNARC effect in different tasks.
    In the first experiment, we presented participants with a specific letter (A, B, D, or E) successively and intensively, and asked them to remember the letter and the number of times occurring in the activating stage. Then, we presented the activated letter again to participants and asked them to classify the activated letter in the order of the alphabet by pressing the left key with the left hand or the right key with the right hand. The results of this experiment showed that the SNARC effect was the result of both magnitude and ordinal cues. In addition, the effects of SNARC on the processing of both magnitude and ordinal cues did not interact with each other. In the second experiment, participants were asked to classify the activated letters according to their magnitude. The results indicated that the SNARC effect in the processing of magnitude and the SNARC effect in the processing of ordinal cues interacted with each other. Besides, the SNARC effect occurred only when the magnitude or ordinal direction was consistent with the response side. In the third experiment, we activated the magnitude of letters by successively presenting a specific letter several times, followed by presenting the activated letter in blue or green to the participants. Unlike the first two experiments, in the third experiment, we asked participants to classify the letters based on their color by pressing the left or right key. The results indicated that the SNARC effect only occurred in the processing of ordinal cues, and was not affected by numerical-spatial consistency.
    This study highlighted that (1) both magnitude and ordinality information can induce the SNARC effect; (2) the influence mechanism of magnitude information on the SNARC effect was different from that of ordinality information, and both of them depended on the task completed by participants. With the change of tasks, the mechanisms of magnitude and ordinal cues in the SNARC effect also changed, indicating their task dependence. These results support and improve the magnitude ordinality dual action theory.

    The cognitive neural mechanism of deinhibition: An ERP study
    CHEN Jiwen, MAI Xiaoqin, LI Fuhong
    2025, 57 (5):  762-774.  doi: 10.3724/SP.J.1041.2025.0762

    When switching flexibly between different tasks, it is necessary not only to inhibit task-irrelevant information but also to overcome the previous inhibition at the appropriate time, that is, to engage in deinhibition. Studies have focused on the deinhibition process associated with implicit cognitive inhibition. They have rarely investigated the deinhibition process related to response inhibition. Since the formation of deinhibition relies on the strong aftereffect of inhibition and response inhibition may produce a stronger aftereffect of inhibition than cognitive inhibition, the exploration of response inhibition can more clearly reveal the cognitive neural mechanism of deinhibition.
    A residue iteration decomposition technique was used to investigate the cognitive neural mechanisms underlying deinhibition in an adapted stop-signal task. Fifty-four Chinese students (24 males and 30 females) participated in the EEG experiment. Participants were required to judge whether to respond to the stimulus according to its color. Different button responses corresponded to different stimuli (“X,” “O”). Participants were told to respond quickly unless a stop signal occurred. Stop signals followed approximately one-third of the stimuli. The stop signal occurred when the color of the stimulus (X/O) changed to red 200 ms after the stimulus onset. In that case, participants were instructed to withhold their response.
    The behavioral results showed that when the preceding trial was a stop-signal trial and participants successfully inhibited the action of the stimulus, the reaction time (RT) for the repeated stimuli in the current trial was significantly longer than that of the switched stimuli, reflecting the cost of deinhibition. The ERP results indicated that the process of deinhibition was manifested by larger P1 and smaller N1 amplitudes at the posterior electrodes, reflecting the role of the attention-gating mechanism in the early stage of deinhibition, which supports inhibition theory. Moreover, the process of deinhibition was also reflected by smaller N2/P3 amplitudes and longer P3/R-cluster latencies, suggesting top-down cognitive control processing and motor-response control processes, which supports memory retrieval theory.
    This study identified the following neural mechanisms underlying the explicit deinhibition process: early attention processing, top-down cognitive control, and response control. These findings provide new evidence that the deinhibition process not only supports inhibition theory but also memory retrieval theory.

    The self-reference effect in prospective memory and its cognitive mechanisms in elementary school students aged 7 to 11 years
    XIN Cong, CHEN Youzhen, TIAN Mi, LIU Guoxiong
    2025, 57 (5):  775-791.  doi: 10.3724/SP.J.1041.2025.0775

    The self-reference effect in prospective memory (PM) refers to the phenomenon in which memory performance for self-referenced planned events or activities, at an appropriate time or situation in the future, is superior to that for other-referenced conditions. Despite its significance, research on the self-reference effect within the realm of PM remains scarce. Elementary school children have a heightened need for PM; thus, focusing on the self-reference effect in this population can provide insights into how they process information related to themselves and others when remembering future events and how the role of “self” can be leveraged to enhance their PM. This study investigated the generation of the self-reference effect in PM and its cognitive mechanisms in elementary school students aged 7-11 years through three experiments, in conjunction with an ownership paradigm.
    This study employed the ownership paradigm for the first time to investigate the existence of the self- reference effect in the domain of PM among elementary school students, using the perspectives of active selection (Experiment 1) and passive allocation (Experiment 2). Findings indicated that elementary school students exhibited superior memory performance for self-referenced PM targets compared to those referenced by others, regardless of whether ownership was determined through active selection or passive allocation. This finding confirms the existence of the self-reference effect in PM among the elementary school students. Furthermore, compared with the 7- and 9-year-old groups of elementary school students, the 11-year-old group exhibited larger self-reference effect in PM.
    In Experiment 3, the focus shifted to directly investigating the processing mechanism of the self-reference effect in PM by manipulating the target salience and the cognitive load of the ongoing task to observe changes in cognitive resources. Under a high cognitive load condition, the self-reference effect in PM was absent in the salient and non-salient target conditions among the elementary school students. Conversely, under a low cognitive load condition, the self-reference effect was observed in the non-salient PM targets but not in the salient targets. This study revealed a notable decrease in response speed during the ongoing task under both high and low cognitive load conditions, compared to the baseline condition. In addition, the elementary school students were significantly slower in responding to the PM targets for self- and other-references than to those for the ongoing task and the baseline condition. Furthermore, under low cognitive load, reaction times for the ongoing task before the emergence of PM targets were considerably slower than those after the targets appeared. The findings suggested that cognitive resources were allocated to monitor the potential context of a target before its appearance, and the monitoring of relevant intentions is reduced post-target emergence. Meanwhile, under a high cognitive load, the reaction times for the ongoing task before the appearance of the self-referenced PM targets were also significantly slower than those after the appearance of the targets. However, no such difference was observed in the reaction times before and after the appearance of the other-referenced PM targets.
    In conclusion, a stable self-reference effect can be observed in the PM of elementary school students when employing the ownership paradigm, with large effects in the upper elementary school grades. The generation of the self-reference effect in PM requires cognitive resources, which are deployed flexibly based on task demands and showcase a dynamic processing characteristic. The finding supports the notion that the self-reference effect in PM involves cognitive resource-intensive dynamic processing, which can further enrich the dynamic processing theory of PM.

    The effects of rumination on social anxiety: The role of negative self-beliefs
    GENG Li, FENG Qiuyang, LI Yu, QIU Jiang
    2025, 57 (5):  792-804.  doi: 10.3724/SP.J.1041.2025.0792

    People sometimes recall social interactions, speculating on others' evaluations and opinions of themselves. When such thinking exceeds normal limits or is persistently accompanied by negative emotions, it becomes distressing, manifesting as rumination. Cognitive theories of social anxiety identify rumination as a pivotal factor in its onset and maintenance. Individuals engaged in rumination often form negative and pessimistic evaluations about themselves, with cognitive elements playing a crucial role. Sometimes, people develop distorted, counterfactual beliefs about themselves and others, termed negative self-beliefs, which are a type of adverse cognition and a core feature of social anxiety. Although the relationships among rumination, social anxiety, and negative self-beliefs have been theoretically discussed, empirical studies confirming their interaction mechanisms are lacking. Thus, the purpose of this study is to explore the significant role of negative self-beliefs in the relationship between rumination and social anxiety.
    The study conducted two experiments designed to provoke social anxiety and prompt participants to engage in state rumination, with the aim of monitoring and analyzing their subsequent emotional responses. Experiment 1 included 83 participants (26 males, 57 females; mean age 21.05 ± 2.15 years). The participants first underwent baseline measurements, followed by a 3-minute timed speech task to induce social anxiety. After this task, the participants were randomly divided into two groups to engage in either rumination or distraction imaging, with changes in negative self-beliefs and levels of social anxiety recorded before and after the tasks. Experiment 2 involved 51 participants (20 males, 31 females; mean age 20.14 ± 1.76 years). The experiment was conducted over two lab visits. In the first visit, the participants learned about and mastered the concepts of social anxiety and negative self-beliefs, recalled, and wrote down four previous social anxiety events and the negative self-beliefs associated with each event. During the second visit, the participants completed a keyboard response task, during which real-time emotional changes were recorded. They dealt with their negative self-beliefs according to the guidance provided under different psychological states of rumination or distraction and used various coping strategies (reacting, observing, and reevaluating) to address the presented negative self-beliefs.
    The results of the data analysis are as follows: Experiment 1 utilized repeated-measures ANOVA and mediation models based on change scores, revealing (1) significant positive correlations among rumination, social anxiety, and negative self-beliefs and (2) that rumination affects social anxiety by sustaining negative self-beliefs. Experiment 2, which used repeated-measures ANOVA, revealed that (1) rumination on social anxiety events triggered more negative emotions; (2) using distraction strategies to alleviate social anxiety resulted in a rebound of negative emotions; and (3) interventions targeting negative self-beliefs proved to be more effective in alleviating social anxiety. Both experiments validated and complemented each other, collectively elucidating the critical role of negative self-beliefs in the impact of rumination on social anxiety.
    In summary, this study explored the impact of rumination and negative self-beliefs on social anxiety, not only validating and enriching the cognitive theories of social anxiety at a theoretical level but also filling empirical gaps in the previous research. First, the experimental results clarify the mediating role of negative self-beliefs in the relationship between rumination and social anxiety, offering a new perspective for understanding the mechanisms underlying the onset and maintenance of social anxiety. This finding deepens our understanding of the interaction between rumination and social anxiety, enhancing theoretical models of social phobia and broadening cognitive models of the onset and maintenance of social anxiety disorders. Second, the research results provide a basis for developing new intervention measures. Given the significant role of negative self-beliefs in maintaining social anxiety, future interventions could focus on directly targeting these self-beliefs, offering new strategies for the clinical treatment of social anxiety.

    Interactive feedback in persuader-persuadee interaction enhances Persuasion: An fNIRS hyperscanning study
    LI Yangzhuo, ZHANG Ruqian, SONG Sensen, LI Xianchun, LUO Junlong
    2025, 57 (5):  805-819.  doi: 10.3724/SP.J.1041.2025.0805

    Persuasion is a fundamental social skill in humans, serving as a crucial foundation for information propagation and social influence. Existing research has predominantly focused on a mechanical understanding of persuasive content, overlooking the interactive nature of persuasion. The current study investigates the effects of interactive feedback on interpersonal persuasion and its underlying neurocognitive mechanisms, utilizing a dyadic persuasion paradigm with high ecological validity in combination with functional near-infrared spectroscopy (fNIRS).
    Participants visited the laboratory on two occasion to complete all tasks: the item selection task (first visit) and the fNIRS hyperscanning dyadic persuasion task (second visit). In the item selection task, participants attended the laboratory individually, where they were instructed to read the Arctic survival scenario, select the three most critical items from a list of 15 items, and rank them according to their significance for survival. The fNIRS hyperscanning task consisted of two phase: a no-discussion phase (no feedback) and a discussion phase (feedback). Additionally, to eliminate the confounding effects of interactive feedback on persuasion that might arise from repeated information processing (e.g., repeated exposure to persuasive content enhancing persuasion) or interpersonal factors (e.g., intimacy, interpersonal distance), two control conditions were included. In control condition 1, both task parts were identical. In control condition 2, phase two involved independent thinking phase, where participants were asked to reflect independently on the other person’s opinions and complete the item selection task. This study primarily focuses on the prefrontal cortex and the left temporoparietal regions.
    The behavioral results indicate that, compared to the no interactive feedback condition, interactive feedback enhanced both persuasion outcomes and perceived persuasiveness. In neural activity, our results showed that interactive feedback strengthened brain-to-brain synchrony between the persuader and the persuadee in the right frontal cortex and left temporoparietal regions, with this synchrony positively predicting persuasion outcomes. Granger causality results further revealed the directional characteristics of the brain-to-brain synchrony, shedding light on the interaction patterns between the persuader and the persuadee during persuasive interaction. Regarding the use of persuasion strategies, compared to supportive strategy, persuaders in the interactive feedback phase more frequently employed refutational strategies. Furthermore, brain-to-brain synchrony under the refutational strategy was significantly higher than under the supportive strategy. Moreover, brain-to-brain synchrony gradually increased after, rather than before, the refutational strategy was employed. This finding confirms that refutational strategies are crucial for promoting persuasion, with the brain-to-brain synchrony between the persuader's left superior temporal gyrus and the persuadee's right frontal gyrus effectively tracking and identifying the use of this strategy.
    In summary, brain-to-brain synchrony serves as a critical neural mechanisms that drives the persuader and persuadee to reach cognitive consensus, thereby facilitating subsequent changes in the persuadee's attitudes and behaviors. The current study provides a novel perspective on how interactive feedback enhances interpersonal persuasion and contributes to a deeper understanding of the complex and authentic persuasion processes through interpersonal neuroscience.

    Threshold effects of distinctiveness: Psychological mechanisms underlying group identity
    KE Wenlin, WEN Fangfang, ZUO Bin
    2025, 57 (5):  820-837.  doi: 10.3724/SP.J.1041.2025.0820

    Our understanding of the self encompasses personal and social identities linked to the groups individuals belong. The way individuals navigate differences between themselves and others along with how this balance influences their identification with the group, have been a central question in the study of human social behavior. Previous studies have treated group assimilation and individual differentiation as separate aspects, yielding conflicting results. In contrast, Brewer's (1991) Optimal Distinctiveness Model defines distinctiveness as the degree to which an individual’s characteristics deviate from group norms, considering personal characteristics on a continuum (e.g., traits, abilities, and physical features). The Optimal Distinctiveness Model in the intergroup context proposes an inversely parabolic relationship between distinctiveness and group identity based on a continuum perspective. However, the influence of distinctiveness on group identity and the specific distinctiveness thresholds in intragroup contexts remain unclear. Building on this, our study systematically explores the impact of distinctiveness on group identity across hierarchical levels and group attributes using a continuum perspective.
    The study comprised three experiments. In Experiment 1, a baseline-level forced-choice task was employed to examine the effect patterns of the two hierarchical levels of distinctiveness on group identity. The independent variable, distinctiveness, ranged from 0 to 1 across 11 degrees, whereas the dependent variable was the dichotomous selection of group identity by participants at various distinctiveness levels. Two hierarchical levels were included to compare differences between self and group means, with the group's variability presented in dual experiment blocks, assuming a lower threshold for comparing levels with the group mean. Building on Experiment 1, Experiment 2 investigated the moderating role of specific group attributes maintaining the core experimental design while incorporating assessment protocols for surface- and deep-level group attributes. Experiment 3 explored the role of group cognitive dissonance, measuring the participants' cognitive dissonance degrees across discrimination levels.
    Adopting a continuum-based analytical perspective, the findings reveal that the impact of distinctiveness on group identity deviates from an inverted U-shape and linear negative model, instead conforming to a logistic regression function characterized by an “S-curve.” Overall, a nonlinear negative effect of distinctiveness on group identity was observed. As distinctiveness increases, group identity follows a pattern of “flat-sudden decline - maintain flat.” The threshold point with the steepest rate of decline in group identity emerged at the middle level of distinctiveness. Beyond this threshold, self-identification within a group diminished. Notably, comparisons with the group mean exhibited a lower distinctiveness threshold than those involving the group’s variability. Similarly, deep-level attributes had a lower distinctiveness threshold than surface-level attributes and aligned more closely with the logistic regression model. Additionally, group cognitive dissonance served a mediating role, with the degree increasing in alignment with distinctiveness following a logistic regression trend. A higher degree of group cognitive dissonance corresponded with a lower level of group identity. The findings showed that group identity does not decline linearly with increasing distinctiveness, but maintains a balance between self and group before the distinctiveness surpasses a threshold level, beyond which group identity declines abruptly and cognitive dissonance rises sharply.
    Adopting a continuum perspective, this research provides comprehensive insights into how distinctiveness influences group identity across various hierarchical levels and attributes, identifying a distinctiveness threshold effect. The effect of distinctiveness on group identity is consistent with an “x-shaped” pattern. The findings illuminate the balancing process between self and group in social identity formation, offering a comprehensive refinement and nuanced expansion of theories within the realm of self and group relations. Practically, this study offers novel insights for individuals to pragmatically navigate the differences between group and self-attributes, promote the maintenance of psychological boundaries, and safeguard mental health. Furthermore, the findings provide a foundation for targeted organizational strategies that foster coordination and cooperation within organizations that enhances team cohesion by identifying the distinctiveness threshold as an early warning signs.

    Are we more empathetic towards stray animals or homeless individuals? An attributional responsibility approach
    JI Tingting, WANG Jia, DING Yi
    2025, 57 (5):  838-859.  doi: 10.3724/SP.J.1041.2025.0838

    Empathy towards humans and animals varies significantly in societal contexts. While homeless individuals face severe survival challenges and social exclusion, public attitudes towards them are generally more negative compared to stray animals, who often receive greater attention, sympathy, and shelter. This research examines potential differences and mechanisms in empathetic responses towards stray animals and homeless individuals, within the framework of responsibility attribution. We hypothesize that participants are more likely to attribute internal responsibility to homeless people for their misfortunes than to stray animals, leading to lower empathetic responses toward homeless people. Furthermore, we propose that this effect is moderated by social dominance orientation (SDO). Specifically, individuals with high SDO are expected to perceive both targets (i.e., stray animals or homeless individuals) similarly, showing smaller differences in empathy and responsibility attribution toward homeless people and stray animals.
    Three experiments were conducted to test the hypotheses. Across all experiments, participants read news articles to manipulate the harsh living conditions or unfortunate events experienced by different empathy targets. Experiment 1 employed a within-subjects design (N = 296), where participants read articles describing the living conditions of stray animals and homeless individuals and subsequently reported their internal responsibility attributions and empathy responses. The results indicated that participants showed lower empathy responses toward homeless individuals compared to stray animals, and this difference was mediated by greater internal attributions of responsibility to homeless individuals. Experiment 2 used a between-subjects design to replicate these findings among members of an animal protection group (N = 208, Experiment 2a) and general population samples (Ns = 217 and 300, Experiments 2b and 2c), demonstrating the robustness of the results. Furthermore, Experiment 2 revealed a moderating role of SDO, showing that individuals with high SDO exhibited smaller differences in internal responsibility attributions and empathy responses between homeless individuals and stray animals. Finally, these empathy differences influenced participants’ donation intentions and behaviors, as they were more likely to donate to stray animals than to homeless individuals.
    To examine the causal mediating role of internal responsibility attribution, Experiment 3(Ns = 400 and 300, Experiments 3a and 3b) further manipulated internal responsibility attribution to test its effect on the differences in empathy responses towards homeless individuals and stray animals. The results revealed that participants showed less empathy towards homeless individuals than stray animals under the control condition. However, in a low or high internal responsibility attribution condition, there was no significant difference in empathy responses towards homeless individuals and stray animals. These findings further validate that internal responsibility attribution is the mechanism driving the differences in empathy responses towards homeless individuals and stray animals.
    In summary, the findings from the three experiments revealed that individuals attribute more internal responsibility to homeless people than to stray animals, leading to lower empathy responses and a reduced willingness to help the homeless. This effect was moderated by individual differences in SDO. Specifically, individuals with high SDO exhibited smaller differences in empathy responses between homeless individuals and stray animals. These findings provide deeper insights into differential empathy responses towards humans and animals and offer implications for welfare and assistance strategies for vulnerable human populations and animals.

    The effects of the menstrual cycle on women’s novel food preferences: The mechanism of food shortage perception
    JIN Chengwen, CHEN Rui, XU Ting
    2025, 57 (5):  860-882.  doi: 10.3724/SP.J.1041.2025.0860

    A woman’s menstrual cycle influences her psychology and consumption behavior. The classic menstrual cycle begins with menstrual onset and lasts approximately 28 days, comprising both the follicular phase (Days 1-14) and the luteal phase (Days 15-28). In particular, mating motivation increases during the follicular phase, and women are more likely to spend money on clothing to help them attract potential mates during the fertility window. During the luteal phase, women tend to spend more on food, and their preferences are characterized by a “desire for generalized food”, as well as “risk avoidance toward specific foods”. For example, women’s bodies are prepared for potential pregnancy, and they have a greater preference for high-calorie food (i.e., sweet foods) and tend to avoid risky food (i.e., genetically modified foods). Novel foods constitute an important category of food, as they have important value for the environment, consumer health, and well-being. Research findings have indicated that people’s preference for novel food is characterized by adaptability. In the present study, we focus on “food exploration behaviors” driven by “food desire” from an evolutionary perspective, examining the impact of the menstrual cycle on preferences for novel food.

    Too pretty to be healthy? The influence of food aesthetics on consumer perception of food healthiness
    ZHENG Xiaoying, ZHENG Lijing, LIU Chunlei, HAN Han
    2025, 57 (5):  883-895.  doi: 10.3724/SP.J.1041.2025.0883
    Abstract ( 883 )   PDF (719KB) ( 1268 )   Peer Review Comments
    In recent years, the impact of food aesthetics on consumer perceptions and preferences has garnered significant attention. Previous studies have largely demonstrated a “what is beautiful is good” effect, revealing that consumers favor foods with visually appealing features (e.g., symmetry, uniformity) while devaluing those with aesthetic flaws (e.g., deformities, blemishes). However, does beauty necessarily equate to healthiness? This research explores how high (versus normal) aesthetic appeal in food influences consumer perceptions, particularly regarding food healthiness. We propose that highly aesthetic foods evoke associations with hedonism and indulgence. Since indulgent foods are often perceived as unhealthy, consumers may view highly aesthetic foods as less healthy compared to those with standard appearances.
    Five studies were conducted to test these hypotheses. Studies 1A, 1B, and 1C (each N = 200) employed a one-way between-subjects design (food appearance: highly aesthetic vs. normal) across various food types (cupcake, steamed bun, banana toast). These studies examined the main effect of food appearance on healthiness perception, the mediating role of hedonism, and ruled out alternative explanations such as taste, price, freshness, and food processing. Study 2 (N = 220, cookie) utilized a moderation approach to further investigate the role of the hedonism-unhealthiness association. Study 3 (N = 100, Osmanthus Cake) examined the downstream consequences of healthiness perceptions induced by food appearance, with or without priming a health goal.
    The key findings are as follows: (1) Compared to foods with normal appearances, highly aesthetic foods evoke stronger associations with hedonism, which subsequently reduces perceived healthiness. (2) Disrupting the intuitive belief that “pleasure equals unhealthiness” mitigates the negative effect of high aesthetic appeal on healthiness perception. (3) When participants were primed with a health goal, their likelihood of choosing highly aesthetic (vs. normal-looking) food decreased, driven by reduced perceptions of healthiness.
    This research challenges the pervasive belief that “what is beautiful is good” by demonstrating that excessive aesthetic appeal in food can backfire, reducing its perceived healthiness. For food marketers, these insights underscore the importance of balancing aesthetic appeal with health-related messaging, especially when promoting products positioned as healthy options.

    Nowadays, billions of people frequently change their residence, and residential mobility has become an essential part of consumers’ lives all over the world. Researchers have recognized the importance of residential mobility and prior research mainly focused on how residential mobility affected individuals’ self-concept and their interactions with others. There are also some research investigating the long-term effects of residential mobility on individuals’ health and education. However, little is known about how residential mobility influences consumers’ product preferences. To fill this research void, this research focused on the feasible and desirable attributes of products and proposed that residential mobility strengthened consumers’ process focus mind-set, which in turn increased their preferences for feasible (rather than desirable) products. In addition, we believed that this effect would not be significant for maximizers, and this effect would also be attenuated when consumers made decisions for others rather than for themselves.
    We conducted ten studies (4 in appendix) to test our hypotheses. Study 1a used secondary data from CHFS to provide preliminary evidence for the relationship between residential mobility and preference for feasible product. Study 1b employed a single factor (residential mobility: high vs. low) between-subjects design and 150 Credamo workers were recruited. We manipulated participants’ residential mobility through a writing task and then measured their preferences for four pairs of products. The results showed that residential mobility increased consumers’ preference for feasible products. In Study 1c, we aimed to measure participants’ preference in a real product choice context to test the robustness of our main effect. This study employed a single factor (residential mobility: high vs. low) between-subjects design, and we randomly recruited university students. We manipulated residential mobility in a different way and told participants that they had the extra chance to win a puzzle to measure their real choice. The results further confirmed the robustness of the effect of residential mobility on the preference for feasible products in a real product choice context.
    In Study 2 we tried to explore the underlying mechanism. This study employed a single factor (residential mobility: high vs. low) between-subjects design. 400 Credamo workers participated in the study. The manipulation of mobility and measurement of preference for feasible products was similar to Study 1b. Then we measured participants’ process focus mind-set. This study not only showed that our proposed effect was driven by process focus, but also ruled out alternative explanations such as abstract thinking, primary focus, sense of control and anxiety. In Study 3a, we employed a single factor (residential mobility: high vs. low) between-subjects design and recruited 434 Credamo workers. We manipulated residential mobility same as Study 1b and measured whether participants were maximier or satisficeer. Results replicated the effect of residential mobility on preference for feasible products and showed the moderating role of maximizer. Finally, in Study 3b, we conducted a 2 (mobility: high vs. low) × 2 (object of decision: self vs. others). Results showed that the effect of residential mobility on preference for feasible products would be attenuated if participants made decisions for others rather than for themselves.
    Taken together, this research demonstrated that consumers with high residential mobility preferred feasible products, which was driven by process focus. For consumers who were maximizers or those who decide for others, this effect would not be significant. Our research not only reveals a novel downstream effect of residential mobility, but also enriches the literature on feasibility preference and process focus. Accordingly, this research yields strong practical implications for marketing strategies.

    Intensive longitudinal data (ILD) is increasing in fields such as psychology and management, yet research on analytical methods for ILD remains relatively scant. Traditionally, the ILD is statistically modeled as a two-level structure, with Level 1 being the time and Level 2 being individuals. Especially, existing analytical methods treat longitudinal moderated mediation as multilevel moderated mediation, without considering the lagged relationship between variables. A possible solution is to use dynamic structural equation modeling (DSEM) for ILD moderated mediation analysis.
    DSEM has recently been used for analyzing intensive longitudinal mediation (ILMed; Fang et al., 2024; McNeish & MacKinnon, 2022) and intensive longitudinal moderation (ILMod; Speyer et al., 2024). However, it remains unclear how DSEM can be employed in analyzing intensive longitudinal moderated mediation (ILMM). The purpose of this paper is to combine ILMed and ILMod based on DSEM and propose a method of moderated mediation analysis that takes into account the temporal order between variables.
    For the 1-1-1 ILMed model where all variables are measured at Level 1 (i.e., all variables are ILD), it might be moderated by variables of Level 1 or Level 2. However, for the 2-1-1 ILMed model (i.e., only the independent variable is measured at Level 2) and the 2-2-1 ILMed model (i.e., only the dependent variable is measured at Level 1), they could only be moderated by variables of Level 2. Therefore, there are four basic types of ILMM models: 2-1-1 ILMed moderated by a level 2 moderator, 2-2-1 ILMed moderated by a level 2 moderator, 1-1-1 ILMed moderated by a level 2 moderator, and 1-1-1 ILMed moderated by a level 1 moderator.
    This paper describes in detail how to construct the above four ILMM models with DSEM, so that empirical researchers can understand which kind of ILMM model meets their needs and how to analyze it. Mplus codes for analyzing all these ILMM models are provided.
    A simulation study is conducted to examine the estimation accuracy of the 1-1-1 ILMed moderated by a level 2 moderator, with the following factors taken into account: sample size (N), number of time points (T), indirect effect sizes, and Level-2 variances and covariances. Results show that the estimates for the average mediation effect components (a and b) and the average mediation effect are generally accurate when N≥100 and T≥10. However, a sufficiently large N and T (e.g., T≥20) are required in order to obtain accurate estimation of Level-2 variances.
    Lastly, we discuss assumptions and the extensions of ILMM based on DSEM. As usual, the models used in this paper are based on the assumption that the time series is stationary. Otherwise, residual DSEM can be employed to detrend in ILMM analysis.
