Midterm 2 Flashcards
attention
the mental process of concentrating effort on a stimulus or a mental event.
input attention
getting sensory information into the cognitive system
controlled attention
deliberate, allocation of mental effort
alertness and arousal
being prepared to attend to some incoming event and maintaining this attention
orientation reflex and response
What orients us?
- Important things
- objects and entities
- the unexpected
- habituation: gradual reduction of the orienting response back to baseline
-social factors
- language
default mode network
a brain system of interacting cerebral regions characterized by coordinated activations that are distinct from the activities of other brain networks
global local distinction
Distinction between levels of information processing focusing preferentially on either details of specific information (local) versus the whole (global)
sustained attention/vigilance
Sustained attention is the ability to focus on an activity or stimulus over a long period of time
Vigilance =
the action or state of keeping careful watch for possible danger or difficulties.
explicit processing
conscious processing, conscious awareness that a task is being performed, and usually conscious awareness of the outcome of that performance.
implicit processing
processing in which there is no necessary involvement or consciousness awareness
word stem completion task
In WSC tasks, participants are usually instructed to complete the stem with the first word that comes into their mind without knowing the number of letters in the target word.
attention capture
Attentional capture is a concept in the scientific literature used to refer to instances in which observers fail to ignore a task-irrelevant stimulus
habituation
a gradual reduction of the orienting response back to baseline
spotlight attention
is the mental attention-focusing mechanism that prepares you to encode stimulus information
feature search
the search for a simple feature
conjunction search
the search for the conjunction of two features.
controlled attention
deliberate, voluntary allocation of mental effort or concentration
inhibition of return
previously checked locations are mentally marked as checked and not returned to
facilitation of return
returning to a previously fixated location
hemineglect
inability to direct attention voluntarily to one side of space so the individual neglects the stimuli presented on that side
selective attention
the ability to attend to one source of information, while ignoring others.
filtering
ignoring distractions
selecting
the mental process of eliminating those distractions
the cocktail party effect
The cocktail-party effect refers to the ability to focus one’s attention a particular stimulus while filtering out a range of other stimuli
dual task method
two tasks are presented such that one task captures attention as completely as possible
shadowing task
to repeat the message out loud as soon as it was heard.
early selection
selection of filtering based on early phases of perception (eg. selection based on physical features of the message such as loudness or location)
late selection
selection of filtering based on the meaning and importance of information (eg. selection based on semantic relevance
divided attention
simultaneously performing multiple tasks (inattention blindness)
attention blink
a delay in a second decision or response cycle if it is required immediately after a preceding decision
automaticity
occurring without conscious awareness or intention and consuming very little resources.
stroop task
assess the ability to inhibit cognitive interference that occurs when processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute
declarative memory
(explicitly memory) long term memory for facts and events that can be consciously reflected upon
procedural memory
a type of non-declarative memory (implicit) that is memory for skill and habits
