Effects of Emotional Faces on Inhibition of Return in Three-Dimensional Space
The present study investigated the interaction between inhibition of return(IOR)and emotional faces processing in 3-D space by incorporating the Posner exogenous cueing paradigm into a virtual three-dimensional(3-D)space.Three independent variables of cue validity(valid vs.invalid),target depth(near vs.far)and valence of emotional face(positive vs.negative)were manipulated.In Experiment 1,emotional faces(positive/negative)were used as the target,and the participants were asked to judge the gender of emotional faces quickly and accurately.In Experiment 2,we used emotional faces(positive/negative)as the cue,and asked the participants to detect the location of the blue ball.The results showed that:1)When emotional faces were used as targets and appeared in near space,there was an interaction between the valence of emotional face and IOR,showing that IOR decreased under negative faces condition.2)When emotional faces were used as cues and the target appeared in far space,there was an interaction between the valence of emotional face and IOR,showing that IOR increased under negative faces condition.The results indicate that IOR is affected by the emotional face processing when attention is oriented or reoriented in the depth.
