Document Summary
Differences in brain structure were observed in rats raised in either enriched or deprived environments. Could affect decisions to adopt: can lead parents to over-stimulate their children before they are even born, can lead people to not adopt older children. Experience-expectant brain growth: brain has evolved to expect a certain amount of environmental input and with this input it can develop normally. Experience-dependent brain growth: brain develops according to personal experiences. Brain maintains some residual capacity for change and growth in adulthood. Flexibility in the timing and type of stimulation required for normal development. Adaptation: biological traits (characteristics) that help an individual survive and reproduce in its habitat. Perform a specific function that makes an organism better suited to its environment. Biological adaptions include perceptual processes and behaviours. Natural selection: differential survival and reproduction of organisms as a result of heritable differences between them: discovered by charles darwin and alfred wallace.
