AI Article Synopsis

  • The study explores how attention works in the foveal area (the center of your vision) compared to perifoveal (the surrounding area) when using different types of cues.
  • The researchers conducted two experiments: one focused on exogenous cues (external, sudden signals) and the other on endogenous cues (internal, intentional signals).
  • Results showed that exogenous cues have a stronger inhibitory effect in the perifoveal region, while the endogenous cues facilitate attention similarly in both regions, suggesting distinct mechanisms for orienting attention in the foveal area.

Article Abstract

The effect of covert attention in perifoveal and peripheral locations has been studied extensively. However, it is less clear whether attention operates similarly in the foveal area itself. The present study aims to investigate whether the attentional orienting elicited by an exogenous or endogenous cue can operate within the foveal area and whether attentional orienting operates similarly between foveal and perifoveal regions. By manipulating exogenous orienting in Experiment 1 and endogenous orienting in Experiment 2, we observed both forms of cueing in the foveal area. Specifically, we observed a larger exogenous cue-induced inhibitory effect (i.e., inhibition of return effect) and a similar endogenous cue-elicited facilitatory effect for the perifoveal relative to the foveal targets. We conclude that exogenous and endogenous orienting subject to two independent attentional systems with distinct modulation patterns in the foveal area.
