Abstract:

Temporal attention refers to the ability of individuals to prioritize information processing based on the timing of stimulus occurrence, which is critical for behavioral responses in daily life. However, whether rhythmic temporal attention is modulated by consciousness state remains unclear. In this study, we employed high-frequency flicker stimulation to manipulate the perceptual awareness level of visual rhythmic stimuli, integrating behavioral measures, hierarchical drift-diffusion model (HDDM) analysis, event-related potentials (ERP), and time-frequency analysis to systematically investigate the modulatory effects of consciousness state on rhythmic temporal attention, as well as the differential processing mechanisms of rhythmic cues at sub-second and supra-second timescales. Results from Experiment 1 showed that rhythmic cues elicited temporal attention effects under both conscious and unconscious states, but the effect was significantly attenuated in the unconscious condition. HDDM analysis further revealed that under conscious states, rhythmic cues reduced individuals’ decision boundaries, suggesting activation of endogenous processing at the decisional level, whereas this effect was absent in unconscious states. Building upon this, Experiment 2 found that the contingent negative variation (CNV) component and alpha oscillation suppression were more pronounced under conscious conditions, further supporting that consciousness state enhance temporal attention by modulating cognitive preparation and attention maintenance mechanisms. Moreover, although the inter-stimulus interval (ISI) of rhythmic cues did not affect the magnitude of temporal attention effects, overall responses were faster in supra-second interval conditions, consistent with predictions from the range-synthetic model of temporal cognition. Taken together, these findings suggest that rhythmic temporal attention is not only dependent on external rhythmic entrainment but may also involve endogenous decision-making mechanisms modulated by consciousness levels.
