Paying Attention (CH. 5) Flashcards
Overt Attention
- Spatial visual selection through overt eye movements
- Foveal information tends to be processed more deeply than peripheral information
Covert Attention
Changes in attention without eye movements
Measuring Bottom-Up Covert Attention
- Cue is a salient stimulus event
- Cue is not predictive of target location (50/50), so it should be ignored
- Endogenous (top-down) vs. exogenous (bottom-attention)
Endogenous Control of Attention
A mechanism through which a person chooses (often, on the basis of some meaningful signal) where to focus attention
Exogenous Control of Attention
A mechanism through which attention is automatically directed, essentially as a reflex response to some “attention-grabbing” input
Inhibition of Return
Slower responses at the cued location for long cue/target stimulus onset asynchronies (SOAs), suggesting location is inhibited
Divided Attention
Our complex environment often demands that we perform multiple tasks simultaneously
Executive Control
The mental resources and processes that are used to set goals, choose task priorities, and avoid conflict among competing habits or responses
Conductor of the Mind: Prefrontal Cortex
- Control one’s thoughts
- Keep goals in mind
- Organize mental steps
- Shift plans and change strategy
- Inhibit automatic responses
- Working memory
Feature Integration Theory
A proposal about the function of attention in “gluing” together elements and features that are in view
Selective Attention
The skill through which a person focuses on one input or one task while ignoring other stimuli that are on the scene
Biased Competition Theory
A proposal that attention functions by shifting neurons’ priorities, so that the neurons are more responsive to inputs that have properties associated with the desired or relevant input
Dichotic Listening
A task in which research participants hear two simultaneous verbal messages; one presented via headphones to the left ear and a second one presented to the right ear. In typical experiments, participants are asked to pay attention to one of these inputs (the attended channel) and are urged to ignore the other (the unattended channel)
Spatial Attention
The mechanism through which people allocate processing resources to particular positions in space, so that they more efficiently process any inputs from that region in space
