Abstract
Current theories regarding factors that influence people’s awareness of their actions have underscored the role of peripheral signals eg proprioceptive feedback and central commands eg the intention to make a response The role of covert attention has been largely underexplored even though attention and awareness have been tightly linked The aim of the current study was to directly examine the impact of shifts of visual attention on people’s awareness of their eye movements as they performed the antisaccade task People tend to be unaware of a high percentage of erroneous eye movements on this task thus lending it to the study of variables that might modulate people’s awareness of their actions In addition this task provides the opportunity to compare two classes of actions voluntary antisaccade and involuntary erroneous prosaccade eye movements and thus to assess whether shifts of covert attention can or cannot override sources of information that may be present when people make voluntary but not reflexive responses We found that shifts of visual attention did indeed influence participants’ awareness of their own eye movements leading them to misperceive reflexive and voluntary movements alike suggesting that covert attention may override both peripheral and central signals to bias awareness
