Abstract:

This paper adopted the endogenous-exogenous spatial cue target paradigm, and three independent variables were manipulated: endogenous validities (valid, invalid), exogenous validities (valid, invalid), and target modalities (visual, auditory, audiovisual). Two experiments of different task difficulty (Experiment 1: Simple Orientation Task and Experiment 2: Complex Discrimination Task) were conducted to investigate the effects of endogenous and exogenous spatial attention on multisensory integration. The results of both experiments showed that exogenous spatial attention significantly decreased the effect of multisensory integration, while endogenous spatial attention did not significantly enhance the effect. In Experiment 2, we also found that endogenous spatial attention has an effect on the process by which exogenous spatial attention attenuates the effect of multisensory integration. The results showed that, different from endogenous spatial attention, the effect of exogenous spatial attention on multisensory integration was not easily regulated by task difficulty. When the task is difficult, endogenous spatial attention affects the process by which exogenous spatial attention decreases the effect of multisensory integration. It is inferred that the regulation of endogenous and exogenous spatial attention to multisensory integration is not independent of each other, but affects each other.

Key words: endogenous spatial attention, exogenous spatial attention, multisensory integration, endogenous-exogenous spatial cue target paradigm, task difficulty
