Document Summary

Critical periods time frames in which certain kinds of experiences are essential for normal development. Organisms go through systematic changes in anatomical &physiological systems across the course of development from conception to maturity: biological underpinnings of psychological development. Development characterized by common patterns: critical periods &tendency for vital systems to develop earlier than systems that are less important for survival. Inputs organisms genes, its environment, &resulting patterns of gene-environment interactions: genes contain inherited instructions (dna) for producing proteins &regulating expression of other genes &the enviro that influences gene expression. Constraints need for viability throughout development, the need for specialized cells to serve particular functions in the body &the need for certain sequential processes to occur at just the right times. Environmental niches different local environments into which people are born &for which people have evolved special adaptations. Dna is stored in chromosomes, found in cell nucleus: occur in pairs in humans w/each parent contributing 1 chromosome containing gene variants (alleles)
