Kin 166 Exam 2 Flashcards

Effector and Receptor Anticipation

• Effector anticipation involves timing personal movements in stable environments and is linked to closed skills.
• Receptor anticipation requires predicting spatial and temporal aspects for success, exemplified by a catcher timing their catch to thwart a runner.

Perceptual Anticipation and Reaction Time

• Perceptual anticipation is the ability to time movements in a sequence, such as in a gymnastic routine.
• Reaction time reflects the duration from stimulus input to the onset of movement. It includes simple, choice, and discrimination reaction types.

Factors Affecting Stimulus Identification

• Stimulus clarity impacts how clearly a stimulus is perceived.
• Brightness and loudness influence stimulus identification.
• Peripheral vision enhances the ability to perceive multiple stimuli simultaneously.

Inverted U-Hypothesis

• The inverted U-hypothesis presents a relationship between arousal levels and performance: low arousal can indicate fatigue, while high arousal can impede performance.
• Optimal performance occurs at moderate arousal levels.

Influencers of the Inverted U-Hypothesis

• Individual differences (inter and intra) affect optimal arousal levels.
• The meaningfulness of tasks can influence arousal and performance.
• Task complexity requires appropriate levels of arousal to facilitate learning and execution.
• Variation in teaching styles and the uncertainty of movements can impact performance and arousal.

Perception and Signal Detection Theory

• Perception involves detecting, comparing, and recognizing information.
• Signal Detection Theory defines the cutoff point for responding to stimuli, indicating detection capacity and the impact of noise on response accuracy.

Components of Signal Detection Theory

• The left curve represents internal noise affecting perception: hunger, pain, anxiety, etc., which can distract individuals.
• The right curve incorporates external signals, with higher intensities and clearer signals improving detection.

States of Arousal

• Underaroused individuals may lack motivation or energy; they recognize stimuli but remain disengaged.
• Overaroused individuals may react intensely to minor stimuli, highlighting the balance needed for optimal performance.

Information Processing Metrics

• Information comparison is analyzed by presenting two stimuli of different intensities for detection.
• Just Noticeable Difference (JND) refers to the minimum difference needed to discern between stimuli accurately.

Memory and Judgment

• Absolute judgment relates to an individual's capacity to match sensory input to stored memories.
• Short-term memory and perception are constrained by time (20-60 seconds) and capacity (7±2 items).

Chunking and Detection in Motor Behavior

• Chunking involves grouping information into meaningful units to aid memory.
• Detection in motor behavior is influenced by activation levels, uncertainty, noise, and arousal.

Adam's Closed Loop Theory

• The theory outlines a process:
  • Memory trace sets intentions,
  • Movement organizer creates motor programs,
  • Movement execution occurs,
  • Error detection compares planned and actual movements.
