The sensory enhancement theory assumes that attentional resources will spread until they reach the boundaries of a cued object, [1] [2] including regions that may be obstructed or are overlapping other objects. [3] [4] It has been suggested that sensory enhancement is an essential mechanism that underlies object-based attention.
Object-based attentional effects are attributed to the improved sensory representation of the object that results from attentional spread (an object-guided spatial selection). [ 8 ] : 1 [ 9 ] : 1 When attention is directed to a location within an object, other locations within that object also acquire an attentional advantage (via enhanced ...
Perhaps one of the most studied sensory integrations is the relationship between vision and audition. [16] These two senses perceive the same objects in the world in different ways, and by combining the two, they help us understand this information better. [17] Vision dominates our perception of the world around us.
Researchers in psychology and cognitive science study perceptual vigilance to understand how attentional mechanisms operate and how they can be influenced by internal and external factors. By investigating the cognitive processes underlying perceptual vigilance, researchers gain insights into human perception, behavior and decision-making. [4]
Automatic and controlled processes (ACP) are the two categories of cognitive processing.All cognitive processes fall into one or both of those two categories. The amounts of "processing power", attention, and effort a process requires is the primary factor used to determine whether it's a controlled or an automatic process.
Areas of active investigation involve determining the source of the sensory cues and signals that generate attention, the effects of these sensory cues and signals on the tuning properties of sensory neurons, and the relationship between attention and other behavioral and cognitive processes, which may include working memory and psychological ...
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.
Sensory modalities may include visual, auditory, tactile, olfactory, and taste. Perceptual learning forms important foundations of complex cognitive processes (i.e., language) and interacts with other kinds of learning to produce perceptual expertise. [1] [2] Underlying perceptual learning are changes in the neural circuitry. The ability for ...
