Attention Flashcards
Theoretical Importance of Attention
Attention underlies the process of memory and learning
Practical Importance of Attention
Attention has a central role in almost all facets of motor skill execution
Defining Attention
Attention has elusive definitions, there are several perspectives for defining attention
Attention as Consciousness
- Attention is an internal and external awareness of the environment
- There are conscious and unconscious neural processes
Attention as Effort or Arousal
- Attention requires mental effort
- Attention can be measured through physiological measures
Attention as a Limited Resource
- People have a limited capacity for processing information from the environment
- Because of this limitation, we have selective attention
Single-Channel/Bottleneck Theories
- Cognitive processes occur in serial order
- There are stages in processing, narrowing what we can pay attention to
Broadbent’s Filter Model
Central-Resource Theories
- We can pay attention to multiple tasks or situations at one time
- First proposed by Daniel Kahneman
- Basic Assumption of Theory
- There’s a central reserve of attentional resources
- There’s a flexible attentional capacity
Factors affecting availability of attentional resources
- Arousal
- Anxiety
Effect of arousal on attentional resources
Positive effect on attention
Effect of anxiety on attentional resources
Negative effect on attention
Competiton for Attention
We have selective attention based upon learning, interests, habits, and needs
Incidental Competition Factors
Sudden capturing of our attention
Intentional Competition Factors
Purposeful direction of attention
Stroop Effect
- Evidence for central-resource theories
- A mental experiment showing that humans are able to process 2 stimuli in parallel during the stimulus-identification stage
Cocktail Party Effect
- The ability to be in a noisy room and listen to the person next to us
- We are able to attend to a stimulus even if we don’t draw attention to it
- Happens when we hear our name
Change Blindness
- We only take in the meaning of what’s going on
- We easily miss lots of possibly important stuff
