CHAPTER 1 — “Evolution of a Field of
Study”
1. The Importance of Movement
● Movement is essential for human survival and interaction.
● It allows: manipulating objects, navigating the environment, communication, and
performing daily tasks.
● Studying movement means understanding:
○ Motor control → how the nervous system organizes movement
○ Motor learning → how movement improves with practice/experience
BIG IDEA: Movement isn’t just physical — it reflects cognitive, sensory, and environmental
processes.
2. Levels of Analysis in Studying
Movement
Behavioral Level (main focus of this book)
● What movements look like, how skilled they are, how they change with practice.
Other levels
● Physiological/neural — brain, spinal cord, sensory pathways
● Environmental/task constraints — how context shapes movement
Key point: Skilled movement emerges from environment × individual × task interactions.
3. Essential Definitions
Motor Performance
Observable behavior at a specific moment in time.
Motor Learning
Relatively permanent change due to practice or experience.
Skill (Guthrie, 1952)
Ability to achieve a goal:
● with maximum certainty
● with minimum energy
● with minimum time
4. Early Foundations (1800s–early 1900s)
Ernst Weber & Gustav Fechner
● Sensory psychophysics.
● Relationship between physical stimulus and perception.
Donders
● Mental chronometry (reaction time).
● Broke RT into stages → important for later information-processing models.
Helmholtz
● Speed of nerve conduction.
Bryan & Harter (1897)
● Learning curves; skill development over time.
Thorndike
● Law of Effect — practice strengthens stimulus–response connections.
Woodworth (1899)
● Identified two components of aiming:
○ Initial impulse
○ Hom feedback-based correction
5. Key Figures in Motor Behavior (Mid-20th
Century)
Nikolai Bernstein (pp. 8–9)
● Introduced degrees of freedom (DOF) problem → how does the body coordinate many
joints/muscles?
● Movement is not reflex chains (contradicted Pavlov).
● Emphasized variability, context, and coordinative structures.
Edwin A. Fleishman (p. 10)
● Created taxonomies of perceptual-motor abilities.
● Used factor analysis to link abilities → performance.
● Important for pilot training and performance prediction.
Paul Fitts (p. 12)
● Fitts’ Law — speed–accuracy tradeoff.
● Movement time increases with task difficulty (distance/target size).
Franklin M. Henry (p. 13)
● “Father of motor behavior in physical education.”
● Proposed specificity of motor abilities (skills don’t rely on one general athletic ability).
● Pushed for laboratory tasks and RT studies.
Jack A. Adams (p. 14)
● Closed-Loop Theory of Motor Learning (1971).
● Emphasized feedback, error correction, and memory.
● One of the most influential learning theories pre–1980.
Steve Keele (p. 15)
● Major contributor to motor program theory.
● Studied timing, reaction time, and cognitive aspects of movement.
H.T.A. (John) Whiting (p. 18)
● Ecological approach.
● Emphasized perception–action coupling in sports performance.
Esther Thelen (p. 19)
● Pioneer of dynamic systems theory in infant development.
● Movement emerges from self-organization, NOT fixed stages.
● Famous for research on infant stepping reflex.
6. Major Theoretical Movements in the
Field
1960s — Cognitive Revolution
● Shift from behaviorism → cognition.
● Information processing becomes dominant.
● Reaction time tasks used to study mental operations.
1970s — Information Processing Model
● Humans process input → choose a response → execute output.
● Strong influence from computer science.
● Basis for motor-program theories.
Motor Program Theories (Keele, Schmidt, etc.)
● Movements are controlled by pre-structured programs.
● Generalized Motor Program (GMP) introduced later.
Dynamic Systems Theory (1980s+)
● Thelen leads the movement.
● Focuses on:
○ self-organization
○ variability
○ attractors
○ constraints (task, organism, environment)
Ecological Approach
● Whiting, Gibson.
● Movement arises from real-world information → affordances.
7. Research Trends (1970s–1990s)
Late 1970s–early 1980s
● Decline in motor learning research.
● Shift toward motor control + cognitive processes.
Late 20th century
● Innovation: motion capture, EMG, computers.
● Renewed interest + more precise experiments.
