study of changes that occur as people/animals change & mature through interaction of nature & nurture continuity view –gradual development discontinuity view –succession of changes in STAGES
Developmental States : period of life initiated by distinct transitions (changes) in physical/psychological functioning Critical period : when an individual is most receptive to certain changes Ex: toilet training, crawling, walking, talking, reading
Definition: unfolding of genetically programmed processes of growth influenced by nature & nurture Process of learning to cope & react in an appropriate way Does not necessarily happen along with aging or physical growth a situation a person deals with helps prepare them for the next
1.) conception 2 weeks = ZYGOTE (fertilized egg) 2.) cell division attach to uterine wall (outer cells placenta, inner cells EMBRYO ) 3.) Nine weeks = fetus 4.) Placenta nourishes fetus & blocks TERATOGENS : substance capable of interfering with fetal development 5.) 250,000 neurons form each minute!
limited instincts/involuntary sensory behaviors grasping reflex – respond to touch rooting/sucking reflex – respond to touch near mouth & cheek postural reflex – sit with support
rapid, genetically programmed growth perceptual skills develop tremendously language acquisition – social interaction & hearing prepare infants to learn languages
inborn pattern of steps to understand vocab. & grammar (Chomsky – Broca’s area of brain is programmed) BABBLING – sequence of sounds; ALL sounds same! ONE-WORD STAGE – overextension is common (“doggie” refers to all animals) 18 mo. – learning accelerates – asking questions to learn new vocabulary: naming explosion TWO-WORD STAGE – range of meaning extends greatly & categories are common
TELEGRAPHIC SPEECH – short, simple sequences of nouns & verbs SYNTAX –sentence structure SEMANTICS – meaning of words (i.e. add “ed” for past tense, “s” for plural, “ing” for action, etc)
