چکیده
Between-trial effects in Stroop-like interference tasks are linked to differences in the amount of cognitive control. Trials following an incongruent trial show less interference, an effect suggested to result from the increased control caused by the incongruent previous trial (known as the Gratton effect). In this study we show that cognitive control not only results in a different amount of interference, but also in a different locus of the interference. That is, the stage of the task that shows the most interference changes as a function of the preceding trial. Using computational cognitive modeling we explain these effects by a difference in the amount of processing of the irrelevant dimension of the stimulus. Locus of the Gratton Effect 3

متن کاملTHE EFFECT OF LOCUS CERULEUS LESIONING ON TONIC AND PHASIC PAIN
Bulbospinal noradrenergic pathways are shown to have an important role in descending inhibition of pain sensation. Locus ceruleus (LC), as a rich noradrenergic nucleus in the brain stem which has projections into the dorsal horn of the spinal cord, was evaluated for antinociceptive activity by using tonic and phasic pain models in the rat. LC-lesioned rats demonstrated moderate increase in ...
