Time-delay model of perceptual decision making in cortical networks - Fig 2
A: The set of stimuli. Each of the 40 distinct faces was morphed from male (1) to female (5). B: Experimental design. Each trial started with the word (man or vrouw) that was presented for 0.2[s]. After the fixation cross (0.25[s]), the face was briefly presented for the period of 0.5[s], followed by a randomized inter-stimulus interval (ISI) in the time range of 5 − 7[s].
