Limitations on Performance

Question 1

what is attention

when attention demands are low

when attention demands are high

Answer 1

Attention is a limited cognitive resource or pool or resources that is available and can be used for different tasks or purposes

When the attentional demands of a task are low, performing a secondary task may not detract from
performance. Example: Washing plates and talking on the phone.

When the attentional demands of a task are high, performance of a secondary task likely has a negative impact on both tasks.
Examples:
1. Texting and driving.
2. Chopping vegetables and holding a conversation

Question 2

Stimulus ID
Parallel processing of sensory info

interference

Answer 2

The ability to process two streams of sensory
information simultaneously.
Different streams of sensory information can be often be processed simultaneously and independently.

Question 3

Response selection
2 types of processing

can practice help with pressure

Answer 3

• • • Controlled processing
      Slow
      Deliberate
      Consciously aware
      High attention demand
      “Novices”
• • • -Automatic Processing
      Fast
      Smooth
      Unconscious performance
      Low attention demand
      “Experts”

Practice can help automatize motor skills performance and free attentional resources for motor decisions.
Pressure can reduce the availability of attentional resources for motor decisions and lead to controlled processing

Question 4

Response programming

Spatially and temporally compatible movements

Answer 4

arms and legs moving independently of each other

Drumming requires the limbs to perform independent
actions while maintaining different rhythms

This task is difficult because the two arms must perform
independent actions. This causes movement
interference.

Question 5

Arousal definition

how does arousal affect performance

Inverted U principle
when arousal is low

Tasks with high, middle, low complexity
why

Answer 5

Arousal refers to the level of excitement produced under stress

Arousal is a key determinant of performance in tasks where the speed or accuracy of motor decisions is important

most people work best at moderate levels of arousal
IZOF-where an individual works the best, individual zone of optimal functioning

when arousal is low, performance is better in complex tasks with high precision demands

High- low arousal, medium- medium arousal. low complexity, high arousal

high complexity, need more resources for and demand for other tasks, so focus can’t be taken up by stress

low complexity, heavy weightlifting, divert more resources to CNS drive
