Inattentional Blindness
Inability to perceive info outside the attentional spotlight
Change Blindness
Inability to detect differences in alternating flashed images
Selective Attention
Focusing on one thing at the expense of all others
Attention as a filter
Desired info passes through; other info is discarded
Cocktail Party Effect
Ability to attend to a specific voice among many (Can notice your name though)
Dichotic Listening Task

Attention Filtering Mechanism
People don’t recall unattended information because it is not processed beyond its simple meaning
Attenuation Model
Suggests that the mind doesn’t fully block unattended information but instead weakens (attenuates) it through a filter-like mechanism
Attentional Load
Amount of cognitive resources a task requires
Low-Load Task
Low difficulty task leaves left-over cognitive resources, that then process extra “flanker” stimuli even when not wanted.
High-Load Task
No cognitive resources left for distractors
Attention and Video Games
Gamers can better distribute their attention outside of the central task.
Automatic Processing
Familiar tasks requiring little/no attention - reading, driving
Divided Attention
Splitting attention across tasks; performance usually suffers
Task Switching
Raid, sequential execution of two or more tasks
Split Attention
Simultaneously processing information from different sources.
Pre-activating/ Readying
Becoming attuned to expected stimuli; quicker responses
Feature-Integration Theory
Attention binds features (colour, shape, motion) into coherent objects
Conjunction Errors
Mistakes in combining features when attention is lacking
Exogenous Control
Attention captured by environment (flashing light)
Endogenous Control
Attention directed by goals/intentions (reading)
