An Selling Point Of Cilengitide
On each trial, participants were presented with either a food or a non-food cue (Figures 1A,B). The cue was either a picture of a food item, a household item or a stationery item and 10 different pictures per category were used AMD3100 during both tasks. A trial started with a central fixation cross for 600 ms, followed by a cue for 500 ms. After the cue, a fixation cross appeared for 200�C1000 ms (randomly chosen), followed by the search array, which consisted of a target (a circle) and a distractor (a square) that appeared randomly to the left or right of fixation (see Figure ?Figure1A1A for an example of a trial in the priming and working memory task). Participants had to press ��c�� if the circle appeared on the left and ��m�� if it appeared on the right, with the maximum response time set at 800 ms. The target and the distractor Tacedinaline ic50 were each flanked by a picture of a food item, a household or a stationery object. The inter-trial interval was 400 ms. In the working memory task, 20% of the trials ended with a memory probe that followed the search display to check that the participants were performing the task correctly and had remembered the cue as instructed. On the memory probe trials an item from the same category as the cue appeared for 3000 ms and the participants indicated whether the item was the same or different to the cue. Participants pressed ��c�� if the item matched the cue or ��m�� if it was different. No memory probes were presented for the priming task; however, in the priming task the cue disappeared after 250 ms on 20% of the trials and a different image appeared in its place. On these trials, participants were required to withhold their response to the search the task. FIGURE 1 (A) Design for priming and working memory tasks. (B) Example of working memory task, representing a food valid, food neutral and food invalid trial. On valid trials, the target was flanked by an image that was the same as the cue and the distractor in the search display was flanked by an image from one of the other cue categories. On invalid trials, the distractor was flanked by an image that was the same as the cue and the target was flanked Cilengitide by an image from one of the other cue categories. On neutral trials, both the target and distractor were flanked by images from categories different from the cue (see Figure ?Figure1B1B for an example of the working memory task, representing food valid, food neutral, and food invalid trials). The trials occurred randomly with equal probability. All pictures were matched on visual characteristics, presented in black and white, sized 480 �� 480 pixels and appeared in the middle of the screen with a black background. A preliminary analysis failed to find any differences in reaction times (RTs) according to whether stationery or household items flanked targets and distractors, on neutral trials (P
