•KINE 3340.03 January 10, 2011 Growth, Maturation & Physical Activity L1- Overview Y.Munro York University Faculty of Health •Motor development is a continuous change in motor behaviour throughout the life cycle, brought about by interaction among the biology of the individual, the requirements of the movement task and the conditions of the environment (refer to Figure 1-1) Motor/Psychomotor (Terms used interchangeably) -Movement related behaviour -Interested in continuous  (ie: learning to walk throughout the life-cycle) -“psycho” because never purely a physical action •For example – are you a good dancer? •Individual (biological/genetic e.g. flexible hips) + environment (extrinsic e.g. skilled dance partner previous learning e.g. salsa lessons) + task factors (e.g. music, warmed up) •Note terms “motor” and “psychomotor” used interchangeably •As an area of study •Previously other developmental domains considered more important (e.g. physical, affective, cognitive) •Previously psychomotor development of significance only as an indicator of developmental concerns (e.g. neurological delay) Growing interest/significance •Alarmingly increasing rates of childhood obesity (obesity now tops tobacco as #1 health risk – American Journal of Preventative Medicine, Jan 2010) •Decreased rates in physical activity •Psychomotor ability/capacity may impact other developmental domains/academic performance •Life span approach to studying psychomotor development •Development is a lifelong process beginning at conception and ceasing only at death •Domains, stages and age periods are artificially separated concepts although they may follow a prescribed trajectory. Age periods are approximate or typical time ranges. •Learning takes place throughout one’s life •Rejects the old notion that one either possesses or does not possess ability •Individuality of the learner – each has a unique timetable for acquisition of movement abilities and movement skills (although it may happen in universal phases) •Environmental and sociological impacts •Adulthood no longer viewed as stable period following childhood/ adolescence. •Interaction between four domains – cognitive, affective, psychomotor and physical Physical  Weight, height, cell structure Affective  Social/emotional, sometimes psychological Cognitive  Intellectual Delay? The Study of Psychomotor Development – History Three distinct phases: 1 Maturational perspective 2 Normative/descriptive 3 Process-oriented Maturational perspective (pre-1940) •Psychomotor development is a function of inborn biological processes that result in universal sequences. •Development occurs through distinctly observable phases (immature to mature) •Johnny and Jimmy twin study – Myrtle McGraw (1935) •Throwing behaviour – Monica Wild (1938) -internally driven, innate -Some truth to that ie) Let’s say you have14 kids - can give them all best tools to learn to walk but they will learn without the crazy expense McGraw study  “Maybe is not just innate” Conclusion? -One child given special attention one more so left to own devices  Some differences but none really significant -Physical/intellectu
