Document Summary
Important theme: movement patterns of the individual are uniquely dependent on the interaction between neural and musculoskeletal systems, neural. Integrity and development of neural systems and cognitive constructs: musculoskeletal. Tenets of life-span perspective: development is a lifelong process, development is multidimensional and multidirectional, biological development. Changes in an individual"s physical nature: cognitive development. Changes in an individual"s thought, intelligence, and language: socio-emotional development. Changes in in the individuals relationship with other people, changes in emotions, changes in personality. Independent and interconnected nature of the types of development: The brain"s development: number of neurons doesn"t change born with about 100 billion, changes in brain structure (learning/neuroplasticity) is a function of increasing and decreasing neural connections (synapses) Dendritic spreading peaks around 2 years old synaptic proliferation increases: synaptic density peaks (most connections) around 6 years old. Synaptic pruning increases (get rid of unnecessary synapses) as you age: fewer connections = more efficient processing system (generally)
