Attention Lecture Flashcards
Input Attention
- Alertness or arousal
- Orienting reflex or response
- Spotlight attention and search
- The nervous system must be awake and able to respond to the environment
- Arousal at the biological level is based on the reticular activating system (RAS)
Explicit Processing
Involves conscious processing; which is conscious awareness that a task is being preformed, and usually conscious awareness of the outcome of the performance
Implicit Processing
Processing with no necessary involvement of conscious awareness
Orienting Reflex or Orienting Response
the reflexive redirection of attention that orients you toward the unexpected stimulus
- We orient to what is different
- We can then divert conscious attention
Habituation
A gradual reduction of the orienting response (or performance) back to baseline
Spotlight Attention and Visual Search
Focused or controlled; not by eyes, but by the MIND
~Priming involves stimuli that are outside of the spotlight that provide a point to which we will orient our eyes
~Stimuli outside of the spotlight may be implicitly processed to some degree
Controlled Attention (Posner and colleagues)
Three distinct networks in the frontal lobe and parietal lobe involved in moving the spotlight.
- Alerting System
- Orienting System
- Executive System
Controlled, Voluntary ATTENTION (Controlled, Selective, and Filtering)
- Controlled Attention: a deliberate, voluntary allocation of mental effort or concentration
- Selective Attention: ability to attend to one source of information while ignoring or excluding other outgoing messages around us
- Filtering or Selecting: Mental processes of eliminating those distractions, eliminating unwanted messages
Assumptions of Attention
1) There is more information that we can pay attention to
2) WE have limits to what we can pay attention to
3) WE can do some things while paying very little attention
4) With practice some things do become automatic
Discrete Task
An experimental task in which the beginning and end are easily identified
Continuous Task
Involves actions which require sustained attention across a considerable amount of time
Bonebakker (1996)
- **Found that people had memory for words learned while under anesthesia
- Found this out by using a word stem completion task; patients were more likely used to words that were heard while they were under anesthesia
Signal Detection Theory
~ Explains how people can maintain vigilance over periods of time
- Prolonged tasks reduce vigilance
- frequency of target affects performance
Multitasking
Divided Attention: When preforming two (or more) tasks at the same time, both tasks reduced performance
Multiple Resource Theory
Describes the ways in which attention is divided:
1) the stages of attention involved
2) Modality of the codes used
3) Modes of output
