PERIODS OF LIFE—SPAN DEVELOPM “Closely associated with the life—span a c to studylilrigxhe various aspects of motor development are designated perio s (stages) of life—spa development representing approximate chronological age behavior” (Gabbard, 2008, p. 11). 16. DEVELOPMENTAL CONTINUUM ‘ “The continuum depicts the phases and stages of lifelong motor development” (Gabbard, 2008, p. 13). 17. COHORT EFFECTS M “Researchers cannot be certain that the behavioral differences are due to age, because all individuals grow up under different circumstances, such as those related to education, nutrition, and habits of physical activity. These circumstances are referred to as cohort effects” (Gabbard, 2008, p. 17). “Lerner (2002), one of the originators, describes this View as part of the more general developmental systems perspective. As bases for behavior and developmental change, both focus on the integrative dynamic relationship between the developing person and the changing context within which he or she lives. However, while the developmental systems model is more comprehensive, with equal attention paid to the contributions of biological and environmental systems, contextualism gives more attention to how context influences personal developmen ” (Gabbard, 2008, p. 24).

These characteristics continue to be affected and modified by the individual’ 5 contextual surroundings” (Gabbard, 2008, p. 24). “Provides insight into an important question in motor development: How do individuals perceive and act on information in the environment? Proposed by Eleanor and James Gibson (1979, 2001), this View contends that infants, for example can directly perceive information in the environment and act with a reasonable response” (Gabbard, 2008, p. 26). AR 20. GIBSON’S ECOLOGICAL PERSPECTIVE fig 21. ECOLOGICAL TASK ANALYSIS MODEL “Providing unique insight into the mechanisms and processes involved in the development of coordinated movement. In brief, as the individual perceives information and desires to act with a motor response, voluntary movement requires the formulation of a motor program (a plan of action)” (Gabbard, 2008, pg. 27). 22.1NFORMATION—PROCESSING VIEW “The information—processing approach depicts the mind as a system through which information flows. Scientists who support this approach have drawn close analogies g between the human mind and a computer. That 1s that the brain and central nervouségggflé. MVTST 199— C1 DEFINITIONS ASSIGNMENT ...
