Module 3 Flashcards
Attention
A resource that is available and that can be used for various purposes
Parallel Processing
2+ streams of info can enter the system and the same time and can be processed together without interfering with each other
Sustained Attention
Maintenance of attention over long periods of work
Cocktail-Party Effect
Humans can attend to a single conversation at a noisy gathering, neglecting most (if not all) other inputs
Looked-but-failed-to-see-accidents
Evidence that the driver looked, but he still drove into the path of a pedestrian/bicycle/other vehicle, causing an accident
Consistent-Mapping Condition
Practicing is most effective until the condition-response generated is related consistently to a particular stimulus pattern
Varied-Mapping Condition
A given stimulus sometimes leads to one response and sometimes to another response
Double Stimulation Paradigm
Subject is required to respond, with separate responses, to each of two stimuli presented very closely together in time
Psychological Refractory Period
The delay in responding to the second of 2 closely spaced stimuli
Psychological Refractory Period Effect Process
Motor system processes the first stimulus and generates the first response
Grouping
If a stimulus is very short (less than 40ms), the motor system responds differently (as if they were one)
The Probe-Task Technique
A method that uses a reaction time task as a secondary task during the performance of a primary, criterion task, to assess the attention demands of the criterion tasks
Arousal
The level of excitement produced under stress
Inverted-U Principle
Increasing the arousal level generally enhances performance but only to a point
Perceptual Narrowing
The tendency for the perceptual field to shrink under stress
