Location-based attention is indicated by
the spatial-cueing effect
, a shorter reaction time (RT) when the target appears at the cued location than at the uncued locations, whereas object-based attention is indicated by the same-object advantage, a shorter RT when the target appears at the uncued end of the cued …
Is attention location space based or object-based?
Space-based attention is a process that allocates attention to a
specific region, or location(s)
, in the visual field, whereas object-based attention directs attention to coherent forms or objects in visual space. In object-based attention, all parts of the attended object are thought to be processed concurrently.
What is object-based attention in psychology?
Object-based attention refers
to the relationship between an ‘object’ representation and a person’s visually stimulated, selective attention
, as opposed to a relationship involving either a spatial or a feature representation; although these types of selective attention are not necessarily mutually exclusive.
What is an example of spatial attention?
For example,
observers were able to attend simultaneously to two different targets located in opposite hemifields
. Research has even suggested that humans are able to focus attention across two to four locations in the visual field. … This perspective suggests that the splitting of spatial attention is flexible.
Does visual attention select objects or locations?
Object-based selection from spatially-invariant representations: Evidence from a feature-report task. Attention
selects objects as well as locations
.
How an object can get attention?
One mechanism for object-based attention involves
attending to perceptual objects that are defined
in a spatial reference frame—a “grouped array.” The grouped array is a spatiotopic map in which locations or features are grouped according to gestalt principles such as similarity (e.g., features similar in color group …
What is covert attention?
Two types of attention are discussed: covert attention is defined
as paying attention without moving the eyes
; overt attention is defined as selectively processing one location over others by moving the eyes to point at that location.
What is spatial attention in deep learning?
A Spatial Attention Module is a module for spatial attention in convolutional neural networks. … Different from the channel attention, the spatial attention focuses
on where is an informative part
, which is complementary to the channel attention.
What is featured attention?
Feature-based attention (FBA)
enhances the representation of image characteristics throughout the visual field
, a mechanism that is particularly useful when searching for a specific stimulus feature.
What is load theory of attention?
Load Theory (Lavie, 1995, 2005) states that
the level of perceptual load in a task
(i.e., the amount of information involved in processing task-relevant stimuli) determines the efficiency of selective attention. … The current study is the first to assess the effect of perceptual load on eyewitness memory.
What causes spatial attention deficits?
The core spatial deficit, a bias in spatial attention and salience mapped in an egocentric coordinate frame, is caused by the
dysfunction of a dorsal frontal-parietal network
that controls attention and eye movements and represent stimulus saliency.
What is a spatial attention deficit?
Orienting deficit is
an index of time to orient attention computed from response at the cued location
as follows: (percent correct with 100 msec cue-to-target interval − percent correct with 1200 msec cue-to-target interval).
Why is visual attention important?
Natural visual scenes are cluttered and contain many different objects that cannot all be processed simultaneously. Therefore, from an operational perspective, visual attention is
a matter of organising multiple brain centres to act in concert to select relevant and to filter out irrelevant information
.
What is an object of affection?
n. 1 a tangible and visible thing. 2 a person or thing seen as a focus or target for feelings, thought, etc. an object of affection. 3 an aim, purpose, or objective.
What does the same object advantage suggest about attention?
The same-object advantage (SOA) effect is usually
cited as evidence for object-based attention
. However, the different-object advantage (DOA) effect, which appears to be the opposite of the SOA effect, has also been reported by some researchers. The present study was designed to resolve this apparent inconsistency.
Is object factor draw our attention quickly?
A moving object draws our attention more easily than a stationary object
. For example, flickering lights draw our attention than non-flickering lights. A moving vehicle draws our attention more than a stationed vehicle.
