Unit 3 - 5: Attention Flashcards
Attention
Alerting focus to something
Vigilance
Global level of alertness of the individual
Overt attention
Direct our gaze to object we are thinking of
Covert attention
Paying attention to one place but focusing on another
Cocktail party affect
Ability to focus our attention on one stimulus among many
Inattentional blindness
Lack of perception of stimuli not being attended to
Voluntary attention
Top down: decide to attend to depending on our interests and goals
Spatial Cuing
Reveal voluntary attention improves processing/ reaction time
Processing pathway determines
Reaction time: complex stimuli take more time because it has more places to go to
Reflexive attention
Involuntary: bottom up (peripheral spatial cuing to test); improves processing time in info is given right away, worsens processing time of delay is too long
Complexity
Adds to reaction time
Feature search
Searching for one particular characteristic
Conjunction search
Searching for something with many specifics features; model real world; slower reaction time
Electrophysiology and attention
Used for high temporal resolution; event related potential (ERP)
ERP components (2)
- N1 peak - hallmark of attended stimulus
- Show plasticity
