I&A; 102 – Study Notes Summary
Module Overview
•
•
•
Integrates knowledge from all HKE 1 modules to understand human health and performance.
Emphasizes: Human information processing, human-environment interaction (Work Systems
Model), applying anatomy, physiology & biomechanics to assess performance.
Assessment: Poster + Presentation.
Why Study HKE?
•
•
Humans are designed to move — locomotion, manipulation, communication.
Focus: Human-centered approach, understanding responses, optimizing interaction.
Task Demands vs Human Capabilities
•
Balance between task requirements and human abilities informs design, training, performance
optimization.
Centre-M Model
•
•
Psychological (why), Physiological (how), Biophysical (what).
Integrates anatomy & biomechanics, cardiovascular & respiratory systems, and human senses.
Human Information Processing (HIP) Stages
•
•
•
•
•
•
1. Sensory Input
2. Perceptual Mechanisms
3. Translatory Mechanism (Interpretation)
4. Decision-making (Effector Mechanism)
5. Motor Output
6. Feedback Mechanism
Sensory Input
•
•
•
Exteroceptors (external) and Interoceptors (internal).
Traditional: Vision, Hearing, Touch. Other: Vestibular, Proprioception.
80% of sensory info comes from vision.
Perceptual & Translatory Mechanisms
•
•
•
Interpret sensory input using working & long-term memory.
Influenced by experience, learned behavior, motivation.
Intersensory integration = combining multiple inputs for effective action.
Decision-making (Effector Mechanism)
•
•
Select motor response based on experience or random if none.
Create motor plan (order, timing, force of contractions).
Motor Output
•
•
Activates muscles with cardiovascular & respiratory support.
Afferent vs Efferent nerve pathways.
Skilled Motor Performance
•
•
Gross Motor Skills – large movements.
Fine Motor Skills – small precise movements.
Physical Fitness
•
Motor/Physical Fitness, Health-related Fitness, Skill-related Fitness.
Health-related Fitness Components
•
•
•
•
•
1. Muscular Strength
2. Cardiovascular Endurance
3. Muscular Endurance
4. Body Composition
5. Flexibility
Skill-related Fitness
•
•
•
•
•
•
1. Speed
2. Agility
3. Balance
4. Coordination
5. Power
6. Reaction Time
Feedback Mechanism
•
•
Internal (interoceptors) or External (exteroceptors) feedback.
Evaluates accuracy, speed, magnitude and adjusts actions.
Sensory–Motor Integration
•
•
Continuous loop between stimuli, sensory input, motor output, feedback.
Enables skill refinement.
Systems Thinking & Application
•
•
Humans as part of larger systems (micro, meso, macro).
Work Systems Model links performance with environment and tools.
