Action slips |
Performing unintended actions, particularly during automatic processes |

|
Automatic processing |
Processing that does not require any focused attention |
|
Bottom-up processing |
Pattern recognition based on features of the stimulus |
|
Closed loop |
Slow processing involving conscious and deliberate attention for learning and switching tasks |
|
Configuration |
Arrangement of features with respect to each other |
|
Controlled processing |
Processing that requires focused attention |
|
Dichotic listening task |
Method for investigating focused attention involving listening to two messages simultaneously |
|
Divided attention |
Attending to more than one stimulus simultaneously |
|
Feature detection model |
Pattern recognition based breaking down the stimulus into its component features |
|
Feature detectors |
Cells in the visual cortex that respond to lines or edges |
|
Focused attention |
Ability to selectively attend to some information stimuli whilst ignoring the rest |
|
Galvanic skin response |
Changes in skin resistance in response to changes in arousal |
|
Identikit |
Drawings of facial features combined to construct a face |
|
Open loop |
Fast processing involving no attentional control for well practised tasks |
|
Parallel processing |
Ability to process more than one stimulus simultaneously |
|
Pattern recognition |
Making sense of and identifying perceived objects |
|
Perception |
Process of making sensory inputs meaningful |
|
Schemata |
Memory sets for whole processes, things and events |
|
Serial processing |
Focusing attention on one stimulus at a time |
|
Shadowing |
Repetition of a message during a dichotic listening task |
|
Split-span procedure |
Method for investigating focused attention involving listening to different information in each ear and writing it down |
|
Stroop effect |
Demonstration of how automatic processes can interfere with tasks requiring controlled processing |
|
Template matching hypothesis |
Incoming stimuli are compared with templates in the long term memory |
|
Threshold level of intensity |
According to Triesman, this is reached if an attenuated channel is selected for attention |
|
Top-down processing |
Expectations and knowledge of a particular context influence the perception of patterns |
