The Influence of Mesolimbic-hippocampal Interactions on Episodic Memory During Active Information Seeking
Temple University
Summary
Participants will complete a treasure task during neuroimaging where they have to learn which keys open a treasure chest, and then they are tested on the contents of the treasure chest.
Description
Study 2 will use a treasure task (employed in C.2.1.1), in which participants select amongst 3 keys to learn which feature of keys unlocks the treasure chest, revealing a trial unique object image (Fig. 8b). On each encoding trial participants view three multi-featural keys and a treasure chest. Each key varies on three dimensions: color (red, blue, yellow), shape of the handle (square, circle, triangle), and number of ridges (one, two, three). On each trial, all 9 dimensions of the keys are represented, but the dimensions represented on each key are randomized across trials. During hypothesis…
