What is the inhibition of return effect?

Definition of Inhibition Of Return (IOR): Inhibition Of Return (IOR) is a well-investigated phenomenon in experimental cognitive psychology: People respond more slowerly to stimuli at locations where they previously (at least 300 ms earlier) viewed a task-irrelevant stimulus (see Klein for review, 2000).

What causes inhibition of return?

Causes of IOR IOR follows the facilitation associated with attentional capture by an event in the periphery but it does not follow a voluntary shift of attention (Posner & Cohen, 1984; Rafal, Calabresi, Brennan, & Sciolto, 1989) in the absence of peripheral stimulation.

How long does inhibition of return last?

Inhibition of return (IOR) refers to an orientation mechanism that briefly enhances (for approximately 100–300 milliseconds (ms)) the speed and accuracy with which an object is detected after the object is attended, but then impairs detection speed and accuracy (for approximately 500–3000 milliseconds).

What is meant by inhibition of return quizlet?

inhibition of return: We find that exogenous cues can improve responding as long as the cue happens immediately, so really close in time to what’s going on. as long as the stimulus happens at a point really close in time, really close to the target experience, you lose performance.

What is the pop out phenomenon?

Visual “pop-out” refers to the phenomenon in which a unique visual target (e.g. a feature singleton) can be rapidly detected among a set of homogeneous distractors (Treisman, 1985; Wolfe, 1994).

What do neglect and Blindsight have in common?

common. With blindsight, a patients KNOWS they are blind in one/both visual field and can turn their HEAD to see the blind visual field. NEGLECT patients cannot do this because they don’t realize they are failing to attend to one side of their visual field.

What is meant by negative priming?

Negative priming is a slow down in response speed and an increase in error rate when responding to an object that had to be ignored previously (Tipper, 1985). In a review paper by Mayr & Buchner, (2007), it is argued that this phenomenon is not just related to the topic “attention”, but also to “memory”.

What is Treisman’s feature integration theory?

Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are “registered early, automatically, and in parallel, while objects are identified separately” and at a later stage in processing.

What is parallel processing in the brain?

In cognitive psychology, parallel processing refers to our ability to deal with multiple stimuli simultaneously.

What does blindsight tell us about consciousness?

As this area is damaged in people with blindsight, light picked up by the eyes is not fully processed, and thus does not make it into the person’s conscious awareness. The information does still get processed however, by other parts of the visual system.

What does blindsight reveal about unconsciousness?

Blindsight is a phenomenon that shows that even when the primary visual cortex is damaged or removed a person can still perform actions guided by unconscious visual information.
