Transcript of Understanding Motor Development

Chapter 1
Understanding Motor Development
A continuous change in motor behavior throughout the life cycle.
Integration of Disciplines
1. Physiology
2. Biomechanics
3. Motor Learning
4. Developmental & Social Psychologies
Life Span & Motor Development
How Do We Understand Development?
In Class Reflection
Describe a movement or sport skill that you have mastered.

Provide an abbreviated list of the Individual, Environmental, and Task Restraints
Change occurs through:
1. Biology of individual
2. Environment
3. Requirements of movement task
1. Fundamental to understanding how we live in a dynamic system.

2. Allows for construction of "best practices" in teaching and learning strategies.

3. Underpinnings of rehabilitation, therapy, intervention.

4. Streamline training choices for successful/ optimized development
Why Study Motor Development?
Motor Development understood via:
What is Motor Development?
Transactional View of Causation in Motor Development
- Physical & Mental Factors
- Heredity
- Biology
- Nature
- Intrinsic Factors
- Experience
- Learning
- Nurture
- Extrinsic Factors
Development artificially separated into stages or "age periods".........

1. Infancy
2. Childhood
3. Adolescence

However, development is age-related but not not age-dependent......

Just typical periods of development based on observation.

Traditional Approach
Acquired Development
Movement Abilities: Maturationally based actions of early infancy.

Movement Skills: Experientially based actions of early childhood and beyond.
Unique to the learner
Types of Research
Longitudinal Design
: Attempts to explain behavior changes over time. Chart various aspects of motor behavior of a group of individuals who are of same age for several years.

Cross-Sectional Method
: Researcher collects data on different groups of people at varying age levels at same point in time. Purpose is to measure age-related differences in behavior.

Mixed-Longitudinal Method
: Combines both previously mentioned methods... follows a cross-section of ages over a long period of time.
**** Serves to validate or refute age-related changes with true developmental changes.
Research-Based Classifications of Development
Chronological Age
: Person's age in month or years

Morphological Age
: Comparison of one's height and weight to normative standards.

Skeletal Age
: Utilizes x-ray to determine skeletal development via carpal bones of hand/wrist.

Dental Age
: Accurate/ Rare method.... Records sequence of tooth development from appearance of first cusp to root closure.

Biological Age
: Progress toward maturity.
a. includes morphological, biological, skeletal, dental, and sexual ages.
Terminology in the Psychomotor Domain
: Underlying biological & mechanical factors that influence movement.

: Internal process that results in consistent changes in behavior seen as evidence of its occurence. Based on experience, education, training, and biology.

Motor Learning
: Aspect of learning in which movement plays a major part. Typically thought of as a permanent change in motor behavior.

Motor Skill
: A learned, goal-oriented, voluntary movement task or action of one or more of the body parts.

Motor Control
: Deals with the study of the neural & physical mechanisms that underlie movement.
Terminology of Movement
: Observable change in the position of any part of the body.

Movement Pattern
: Organized series of related movements.

Fundamental Movement Pattern
: A basic locomotor, manipulative movement. Involves combination of movement patterns of 2 or more body segments. (running, jumping, throwing).

Movement Skill
: Similar to motor skill however more refined control required (accuracy).... popular in coaching sciences.

Sport Skill
: Refinement of combination of movement skills to accomplish a sport/ competitive task.
Very Fundamental Movement Pattern
