PSYCH 130 Lecture Notes - Lecture 4: Ejaculation, Prefrontal Cortex, Spermarche
Document Summary
Reflexes are inborn, automatic responses to a form of stimulation: crying, grasping, walking, swimming. Motor development: development time varies, studies have shown that walker babies are late walkers compared to those who do(cid:374)"t spe(cid:374)d as (cid:373)u(cid:272)h ti(cid:373)e i(cid:374) the (cid:449)alker, gross vs fine. Easier to control legs, so instant reach is with their feet. Proteins, vitamins and mineral, carbohydrates, fats: bottle vs breast. Breast fed babies tend to accept new food more readily. Breast fed babies tend to have higher iqs. Brain development: myelination fatty insulation grows around axons to speed up messages, neurons specialized cells that process information and allow communication in the nervous system, synapses. Children have much more synapse growth until they go through synaptogenesis. The brain is more active as a young child and decreases as an adult. The young brain generates too many synapses that are redundant and useless. Physical and chemical damages to the brain are more easily recovered from at a younger age.
