What is an example of stimulus-driven attention?
Stimulus-driven attention includes aspects of both bottom-up and top-down attention. For example, stimuli that contain novel characteristics such as a unique color or motion trajectory are likely to interrupt the goal-directed deployment of attention in a bottom-up manner (i.e., “pure” salience; Yantis 1993).
What is stimulus-driven processing?
In a stimulus-driven process, a stimulus activates an association between the representation of stimulus features (S) and the representation of a response (R). The latter representation can also be called an action tendency.
What is attention stimulus?
Attention can be thought of as the allocation of limited processing resources: your brain can only devote attention to a limited number of stimuli. Attention comes into play in many psychological topics, including memory (stimuli that are more attended to are better remembered), vision, and cognitive load.
What are the mechanisms of attention?
Using paradigms without structural uncertainty, we found converging evidence from psychophysics, neurophysiology, and function imaging that attention improves performance via two major mechanisms: Stimulus enhancement and External noise exclusion.
What is stimulus discrimination distinction?
Stimulus discrimination is a term used in both classical and operant conditioning. It involves the ability to distinguish between one stimulus and similar stimuli. In both cases, it means responding only to certain stimuli, and not responding to those that are similar.
What is stimulus salience?
the importance, intensity, and detectability of a stimulus. Higher salience is usually associated with quicker learning.
What is conceptually driven processing?
By. a cognitive process which centers mostly on the significant facets of a stimulant instead of its perceptual facets. This is top-down processing wherein synthesizing of sensory inputs are led by ideas obtained from enduring events or learning.
What is an example of stimulus discrimination training?
For example, if a child responds “4” in the presence of the question “What is 2 + 2,” the behavior of saying “4” will be reinforced, but saying “4” will not be reinforced in the presence of the question “What is 2 + 5?” Accordingly, the child is trained to discriminate between those stimuli that do and do not signal …
What is stimulus generalization example?
Stimulus generalization is the tendency of a new stimulus to evoke responses or behaviors similar to those elicited by another stimulus. For example, Ivan Pavlov conditioned dogs to salivate using the sound of a bell and food powder.
