System identification in Priming of Pop-Out
Inter-trial repetitions of a target's features in a visual search task reduce the time needed to find the target. Here I examine these sequential dependencies in the Priming of Pop-Out task (PoP) by means of system identification techniques. The results are as follows. Response time facilitation due to repetition of the target's features increases linearly with difficulty in segmenting the targ...
متن کاملPermeability of priming of pop out to expectations.
It is well established that repetition of the same target color across consecutive trials enhances search efficiency for pop-out targets; this phenomenon is known as Priming of Pop out (PoP). In three experiments, we addressed whether PoP interacts with top-down expectations in altering target visibility, which was manipulated via metacontrast masking. The target color either remained the same ...
متن کاملHuman Frontal Eye Fields and Spatial Priming of Pop-out
"Priming of pop-out" is a form of implicit memory that facilitates detection of a recently inspected search target. Repeated presentation of a target's features or its spatial position improves detection speed (feature/spatial priming). This study investigated a role for the human frontal eye fields (FEFs) in the priming of color pop-out. To test the hypothesis that the FEFs play a role in shor...
متن کاملPositional priming of pop-out: a relational-encoding account.
Three experiments examined whether positional priming of pop-out is modulated by target salience. In Experiment 1, the singleton target appeared among variable numbers of distractors (2, 3, 5, 7; blocked presentation). While facilitation of target locations was not influenced by distractor number, inhibition of distractor locations was evident only with two distractors in the display. In Experi...
متن کاملRepeated Electroconvulsive Shock Produces Long-lasting Increases
Electroconvulsive shock (ECS) is a highly effective therapy for the treatment of major depression, but its mechanisms of action are not known. We report that repeated ECS in rats produces enduring changes in two clinically relevant stress-responsive brain systems: (a) the hypothalamic-pituitary-adrenal axis regulated by corticotropin-releasing hormone (CRH) in the paraventricular nucleus; and (...
