Previous studies have proposed that attention is not necessary for detecting simple features but is necessary for
binding them to spatial locations
. The present study tested this hypothesis, using the N2pc component of the event-related potential waveform as a measure of the allocation of attention.
Is feature binding dependent on attention?
In keeping with these proposals, Wheeler and Treisman
Does feature binding require attention?
Although feature integration theory was initially proposed for the visual modality, several reports evidence that
attention is essential for feature binding within the auditory modality
as well. … These behavioral data are in agreement with the view that feature binding is a nonautomatic attention-dependent process.
What is the feature integration theory of attention?
The feature-integration theory of attention suggests
that attention must be directed serially to each stimulus in a display whenever conjunctions of more than one separable feature are needed to
characterize or distinguish the possible objects presented.
What does feature binding mean?
Feature binding is
a process that creates an integrated representation of an object
. … Feature binding is the process by which different characteristics, such as, orientation, size, shape, color, and location, are integrated to create an object.
What is maintenance attention?
Attention maintenance has been described as
a form of cognitive self-regulation
. It refers to the infant’s growing ability to exercise control over his attention or concentration (Bronson 2000). … The ability to maintain attention/concentration is an important self-regulatory skill related to learning.
What is the neural evidence for 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 are the two steps in Treisman’s feature integration theory?
The pre-attention phase is an automatic process which happens unconsciously. The
second stage is focused attention in which an individual takes all of the observed features and combines them to make a complete perception
. This second stage process occurs if the object doesn’t stand out immediately.
What is feature detection theory?
the
theory that all complex stimuli can be broken down into individual parts (features)
, each of which is analyzed by a specific feature detector.
What is binding problem in psychology?
the theoretical issue of how the brain perceives and represents different features, or conjunctions of properties
, as one object or event.
What does the binding problem ask?
The segregation problem, also known as binding problem 1 (BP1), is
the problem of how brains segregate elements in complex patterns of sensory input so that they are allocated to discrete “objects”
.
What is the binding problem of consciousness?
Definition. The segregation problem, also known as binding problem 1 (BP1), is
the problem of how brains segregate elements in complex patterns of sensory input so that they are allocated to discrete “objects”
.
Where does feature binding occur?
Pre-attentive (bottom-up) binding of features can occur thanks to processes (i.e., coding of features conjunctions in single neurons and synchronized firing of separate neurons coding different features) that take place in
cortical regions involved in early steps of visual analysis
(as early as V1; e.g., Seymour et al. …
What are the symptoms of a plant in need of a good preventive maintenance department?
It
locates weak spots (such as bearing surfaces, parts under excessive vibrations, etc.) in all equipment
, provides them regular inspection and minor repairs thereby reducing the danger of unanticipated breakdown.
What is an example of feature integration theory?
Treisman’s Feature Integration theory was originally developed to explain a set of findings using stimuli in which target and distractors differ only in the conjunction of features. For example,
the target might be a horizontal blue line within a field of horizontal green lines and vertical blue lines
.
What is a divided attention task?
Divided attention occurs
when we are required to perform multiple tasks at the same time and attention is required for successful performance on all tasks at hand
(e.g. Trail making task part B (TMT-B)), while measures of sustained attention typically involve sequential presentation of stimuli over a period of time …
