Reasons for Studying Developmental Psych
Raising Children, Choosing Social Policies, Understanding Human Nature
Plato Basic Views
Nurture, Boys are particular challenge, Self-Control and Discipline as most important goals of education, children have innate knowledge
Aristotle Basic Views
Nurture, fitting child rearing to the needs of the individual child, all knowledge comes from experience
Rousseau Basic Views
Nature, maximum freedom from beginning, children learn from their own interactions with objects and people (not from instruction), no formal education before 12
Locke Basic Views
Nurture, tabula rasa, development largely reflects the nurture given by parents and society, avoid indulging child
Reliability
the degree to which independent measurements using the same instruments are consistent
Inter-Rater
the amount of agreement in observations of different raters who witness the same behavior
Test-Restest
the degree of similarity of a participant’s performance on two or more occasions
Validity
does the test measure what it is intended to measure
Internal
the degree to which effects observed within experiments can be attributed to the factor that the researcher is testing
External
the degree to which results can be generalized beyond the particulars of the research
Themes of Development
Nature & Nurture: environment vs genes
Active Child: what role individuals play in their own development
Continuity & Discontinuity: steady or fast changes
Mechanisms of Developmental Change: how and why does change occur
Sociocultural Context: physical, social, cultural, economic and historical circumstances
Individual Differences: possible sources of variation
Children’s Welfare/Social Policy: practical benefits of developmental research
Gastrulation
single layer embryo folds itself into 3 layers, U-shaped groove down center to top layer, folds at top of groove fuse creating neural tube, neural tube then develops into the brained spinal cord
Cell Division
zygote divides into two equal parts, then continues to divide, continues over course of 38 weeks
Cell Migration
movement of newly formed cells away from their point of origin
Cell Differentiation
cells start to specialize, cell’s location influences its future development via chemicals and cell to cell contact with neighboring cells
Cell Death
apoptosis, cell suicide, the formation of fingers depends on cell death
Cephalocaudal Development
Head before Body
Trunk before Legs
Hands before Feet
genotype
inherited genetic material
Phenotype
observable expression of the genotype, including body characteristics and behavior
Why so much REM sleep early on
high level of of brain activity that occurs during REM sleep may help to make up for the natural deprivation of visual stimulation. the jerking movements that occur during REM sleep may give infants opportunities to build sensorimotor maps
