Match to delayed sample task for visuospatial working memory. A fixation period of 2000–3000 ms is followed briefly by the indication arrow (200 ms), which informs participants of the hemifield that they should memorize. After the indication arrow disappears, a sample stimulus, which is an array of squares, is presented for 100 ms on both hemifields, which are separated by a fixation cross. A retention period lasting for 900 ms follows, and a match stimulus is subsequently presented for 2000 ms. During the presentation of the match stimulus, participants are asked to indicate whether the colors of the squares on the hemifield indicated by the indication arrow matched the colors of sample stimulus.
