20 Cards in this Set

  • Front
  • Back

Attention

The mental process of concentrating effort on a stimulus or mental event; the limited mental energy or resource that powers the mental system

Explicit Processing

Involving 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 of conscious awareness (reflex)

Orienting Reflex (Orienting Response)

The reflexive redirection of attention that orients you toward the unexpected stimulus (ex. Sudden noise in a quiet library)

Habituation

A gradual reduction of the orienting response back to baseline with repeated stimulation (ex. Getting used to the noise of the fan in the library)

Spotlight Attention

The covert focusing of attention that prepares you to encode stimulus information

Inhibition

A mental process that restrains behaviour or impedes another mental process; we are slower to return to a location where attention has recently been drawn to move to a new location

Foveation

An eye movement that places the region of a scene that requires fine, detailed processing onto the sensitive fovea

Controlled Attention

The deliberate, voluntary allocation of mental effort or concentration

Selective Attention

The ability to attend to one source of information while ignoring or excluding ongoing messages

Filtering (Selecting)

Especially in auditory perceptions, unwanted, unattended messages are filtered or screened out so that only the attended message is encoded into the central processing mechanism (e.x. Broadbent's filter theory)

Dual Task Procedure

A method in which two tasks are performed simultaneously, such that the attentional and processing demands of one or both tasks can be accessed and varied

Shadowing Task

A task in which the subjects hear a spoken message and must repeat the message out loud in a very short time; often used as one of the two tasks in a dual task method

Pertinence

The momentary importance of information, whether caused by permanent or transitory factors, especially in Norma's theory of selective attention

Attentional Blink (Psychological Refractory Period)

Temporary slow-down in mental processing due to having recently and actively processed another task relevant event

Automatic, Automaticity

Occurring without conscious awareness or intention and consuming little if any of the available mental resources; that point where an instance always win the race with the algorithm

Priming

Mental activation of a concept by some means, or the spread of that activation form one concept to another; also, the activation of some target information by action or a previously presented prime; sometimes loosely synonymous with the notion of accessing information in memory (seeing the colour red)

Hemineglect (Hemi-inattention)

A disorder of attention in which half of the perceptual world, often the left, is neglected to some degree or cannot be attended to

Interference

The incongruent condition (RED) is slower than the neutral/ control condition (XXX)

Facilitation

The congruent condition where (GREEN) is faster than the neutral/ control condition (XXX)
