Abstract
Eighteen subjects performed two visual searchtasks, characterized by different cognitive load,which required to identify a vertical segmentbetween other segments, all with the same orientation,and a distractor that could be presented ornot. By varying the orientation of both targets anddistractors, it was manipulated the salience and thesimilarity between them, deemed considerable forbottom-up and top-down components respectively.Results showed a salience by similarity interaction,suggesting that, while in high cognitive loadconditions endogenous and exogenous components can act independently, when the task requires mildattentional resources, the two processes give rise toan interaction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
