Attention and Consciousness Flashcards
What are the four different types of attention?
signal detection and vigilance, search, selective attention and divided attention
The means by which we actively process a limited amount of information from the enormous amount of information available through our senses, our stored memories, and our other cognitive processes:
Attention
more directly concerned with awareness - it includes both the feeling of awareness and the content of awareness, some of which may be under the focus of attention:
consciousness
We try to detect the appearance of a particular stimulus. Air traffic controllers, for example, keep an eye on all traffic near and over the airport:
signal detection and vigilance
We try to find a signal amidst distracters, for example, when we are looking for our lost cell phone on an autumn leaf-filled hiking path.
search
We choose to attend to some stimuli and ignore others, as when we are involved in a conversation at a party:
selective attention
We prudently allocate our available attentional resources to coordinate our performance of more than one task at a time, as when we are cooking and engaged in a phone conversation at the same time:
divided attention
nontarget stimuli that divert our attention away from the target stimulus
distractors
Scan the environment for a specific feature:
feature search
Look for a particular combination of features:
conjunction search
Target is defined by a single feature, according to this theory the target should also “pop out”, no attention required, parallel search:
Treisman’s feature integration theory
Physical similarity between targets and distractors makes search harder:
similarity theory
This theory has 2 consecutive stages: activation of all target features (parallel) and then evaluate each of activated elements (serial)
Guided search theory
According to what theory of selective attention do we filter information right after we notice it at the sensory level?
Broadbent theory of attention
According to what theory of selective attention do we instead of blocking stimuli out, the filter weakens the strength of stimuli other than the target stimulus?
Treisman’s attenuation model of attention
According to what theory of selective attention are all stimuli processed to the level of meaning, but relevance determines further processing and action?
Deutsch & Deutsch late-filter model
automatic processes are rapid and occur in parallel. They can be used to notice only physical sensory characteristics of the unattended message. But they do not discern meaning or relationships:
pre-attentive processes
These processes occur later. They are executed serially and and consume time and attentional resources, such as working memory. Can also be used to observe relationships among features. Serve to synthesise fragments into a mental representation of an object:
attentive, controlled processes.
Being prepared to attend to some incoming event, and maintaining this attention:
alerting
The selection of stimuli to attend to
orienting
Processes for monitoring and resolving conflicts that arise among internal processes. These processes include thoughts, feelings, and responses:
Executive attention
an inability to detect changes in objects or scenes that are being viewed:
change blindness
An attentional dysfunction in which people ignore half of their visual field that is contralateral to (on the opposite side of) the hemisphere of the brain that has a lesion:
spatial neglect/ hemi-neglect
becoming accustomed to a stimulus so that we gradually pay less and less attention to it:
habituation
