What was the Schneider and shiffrin 1977 experiment?

Shiffrin and Schneider proposed a general theory of attention that postulates the existence of automatic and controlled search processes. They concluded that automatic processes develop when the mapping between stimuli and responses is consistent and controlled processing occurs when the mapping is varied.

Who developed the theory of automatic versus controlled processing?

Forster and Lavie found that the ability to focus on a task is influenced by processing capacity and perceptual load. Processing capacity is the amount of incoming information a person can process or handle at one time. Perceptual load is how difficult the task is.

What is automatic attention in psychology?

Introduction. Automatic attention is an adaptive tool for detecting and enhancing processing of salient events from an evolutionary perspective. Attention can be conceptualized to have two functions: voluntary (endogenous) attention, and automatic (exogenous) attention (Carretié, 2014).

What is object based attentional failure?

Lamy and Egeth found object-based attentional effects when attentional shifts during tasks were required, but no attentional effects when the shifts were not required. Attentional shifting theorises that the cost of switching between objects, rather than within objects, occurs due to three individual components.

What is selective attention in psychology?

Selective attention refers to the processes that allow an individual to select and focus on particular input for further processing while simultaneously suppressing irrelevant or distracting information.

What is the difference between automatic processing and controlled processing?

Automatic processing is quick, parallel, requires little effort, is not easily controlled, and is not sensitive to stressors. Controlled processing is slow, serial, requires attention and effort, is easily controlled, and is sensitive to stressors.

What are 3 examples of automatic processing?

Any information processing that occurs involuntarily and without conscious intention or control, as in the performance of well-practised activities such as seeing, reading, riding a bicycle, playing a game, or driving a car.

What was the main finding in the Egly driver and Rala 1994 experiment?

Egly, J. Driver, and R. D. Rafal (1994) provided evidence for an object-based component of visual orienting in a simple cued reaction time task.

Why is attention object-based?

Research into object-based attention suggests that attention improves the quality of the sensory representation of a selected object, and results in the enhanced processing of that object’s features.

What are the three theories of selective attention?

There are three models that are associated to selective attention. These are the models of attention by Broadbent, Treisman, and Deutsch and Deutsch. They are also referred to as bottleneck models of attention because they explain how we cannot attend to all sensory input at one time in the conscious level.

What is the main advantage of automatic processing?

The huge advantage of automatic processing is efficiency. When the filtering software is running automatically, it is making thousands of decisions for us without requiring us to expend any effort.
