Topic 7- Part 2
Think about..?
• What cognitive and non-cognitive factors that limit attentional controls in the execution
of motor skills?
• What are the cortical region that supports basic attentional processes*** (3 final exam
question)
Attention as a filter
• Considers attention to be foxed and undifferentiated capacity, but mediated by:
• Arousal and anxiety level
• Specific task demands
• Selectivity
Arousal
• Level of activation or excitement of the CNS varies widely from very low during sleep to
very during threat to self
• You can moderate the levels of arousal
• People who can moderate their arousals are better math test takers
• Arousals in the middle → best performance
• Discrete motor tasks like power lifting→ people need higher arousal
• Chess player → lower level of arousal
• So the appropriate amount of arousal depends on the task you are performing
Specific task demands
• The environment of a performer can influence capacity of attentional resources
• In some situations you can modulate the amount of attention required for the task
• Golf players → attend only to the golf ball so amount of attention in their system is
shrunken down
• So now if anything else comes in the way it exceeds their attention pool and can throw
them off their game
• Size of attentional capacity can be influenced by the activity you are performing.
Sometimes its large, sometimes its small.
Selectivity
• How attention is modulated
• Conscious control- visual search
• Unconscious control – environmental stimuli (cueing)
• Exogenous orientation of attention is involuntary
• Endogenous orientation of attention is voluntary
• Endogenous-- > involves high level cognition
• Exogenous→ attention captures, your attention can be grasped → if you see a flash in
periphery

Document Summary
Topic 7- part 2: what cognitive and non-cognitive factors that limit attentional controls in the execution of motor skills, what are the cortical region that supports basic attentional processes*** (3 final exam question) Attention as a filter: considers attention to be foxed and undifferentiated capacity, but mediated by, arousal and anxiety level, specific task demands, selectivity. Specific task demands: the environment of a performer can influence capacity of attentional resources. Attentional capacity and instructions: attention directed towards the initiation (and sometimes termination) of a movement is critical, automate elementary components of a skill prior to integrating additional movement constraints. Putting to the test (leavitt, 1979: six age groups (6,8,10,11,14,19) performing in each of our experimental conditions, skating only, skating only and identifying geometric figures, skating and stickhandling, skating, stickhandling and identifying figures. It was about modulating attention: skating speed was examined in each age group in each experimental group.
