What is an example of exogenous attention?

Indeed, visual tasks exploring exogenous attention typically consist of asking participants to direct their endogenous attention to a particular element (e.g., “the orientation of the line within the green circle”) presented among other, irrelevant, endogenously unattended elements or distractors (e.g., green diamonds …

What is endogenous and exogenous control?

Endogenous factors are associated with top-down voluntary control, while exogenous factors are associated with stimulus-driven control that is thought to take place automatically.

Which of the following is a difference between focused and divided attention?

Focused attention is paying attention to one thing or task. Divided attention is paying attention to more than one thing or task.

What is the key difference between exogenous and endogenous attention in terms of where the brain circuits begin?

The brain circuit for exogenous attention begins in sensory areas such as the visual cortex, whereas the circuit for endogenous attention begins in the prefrontal cortex. Video 5 showed that there are several structures involved in selective attention, and therefore potentially implicated in the development of ADHD.

What does endogenous mean in psychology?

adj. originating within the body as a result of normal biochemical or physiological processes (e.g., endogenous opioids) or of predisposing biological or genetic influences (e.g., endogenous depression). Compare exogenous. —endogenously adv.

What is exogenous control of attention?

In endogenous control, attention is directed toward the stimulus voluntarily, usually by interpreting a cue that directs one to the target, whereas in exogenous control, attention is automatically drawn towards a stimulus The neural mechanisms in the brain have been shown to produce different patterns of activity for …

What is exogenous control?

Exogenous control – A control that is spiked in the sample. For example, DNAs with known concentrated and sequences added to samples as controls. Endogenous control – A control that is present in the sample. For example Actin RNA in a RNA sample.

What is the difference between focus attention and concentration?

Technically, focus relates to the (better definition of) lateral extent (breadth/ range/ coverage), while concentration is about depth. In other words, as you focus more and more, your attention is confined to a smaller and smaller area. When you concentrate on something, the depth of your attention is greater.

What is an example of divided attention?

Divided attention occurs when mental focus is directed towards multiple ideas, or tasks, at once. This skill is also known as multitasking, which people often carry out without realizing it. A great example of this would be singing along to a song while driving a car.

What is difference between attention and concentration?

Attention is an on and off activity and we can choose to pay attention to something or not. On the other hand, concentration has levels or degrees though it is hard to measure these levels. Paying attention to something or activity is like focusing the spotlight of a torch in the dark.

What is volitional attention?

Volitional (Voluntary Attention): Volitional attention exercises the will and demands our conscious effort for arriving at a solution or achieving certain goals. This kind of attention does not depend on the stimulus but depends essentially on the attentive capabilities of an observer.

What is the difference between endogenous and exogenous variables?

1. Endogenous variables: Variables that are explained by other variables within a model. 2. Exogenous variables: Variables that are not explained by other variables within a model. When using regression models, researchers are often interested in understanding the relationship between one or more explanatory variables and a response variable.

Do endogenous and exogenous attention have the same neural substrates?

With this evidence, it has been suggested that although endogenous and exogenous attention may rely on the same neural substrates, the former may be relying on frontal-to-parietal processes while the latter relies on parietal-to-frontal processes ( Baluch and Itti, 2011, Li et al., 2010 ).

Do fMRI results distinguish between reflexive and endogenous attention?

Despite behavioral and electrophysiological evidence for dissociations between endogenous (voluntary) and exogenous (reflexive) attention, fMRI results have yet to consistently and clearly differentiate neural activation patterns between these two types of attention. This study specifically aimed to …

Why is quantity the exogenous variable in this equation?

Because the relationship between price and quantity is known (it is the coefficient b) it is considered endogenous to the model. Quantity is on the left hand side so it is considered the dependent variable (but also endogenous). The exogenous are all considered within the a variable, which gives us the intercept.
