Abstract
Environmental context dependent effect refers to better memory performance of items when the study and test contexts (cf. backgrounds) are congruent than when they are incongruent. The present study examined the effect of congruency between study and test backgrounds on the false recognition. At the study, list of words (light, moon...) which related to a lure (sun) were presented on a background context. After 1 day, at the test, recognition test was conducted in the congruent condition in which the test words were presented on the same background as the study or in the incongruent condition in which the test words were presented on the different background. The results showed that old responses to the studied items and the lure increased when the backgrounds between study and test were congruent than when they were incongruent. This finding indicates that activation of items at the study mediates environmental context dependent effect.
