PS102 Study Guide - Final Guide: Fetal Alcohol Spectrum Disorder, Olfactory Bulb, Cocktail Party
Document Summary
Naturalistic, surveys, case studies, experiments & quasi-experiments (not completely controlled) are some ways of testing hypothesis. Descriptive stats give basic info about data, such as the mean, median, mode & standard deviation (variability). A correlation is: positive (both variable goes up w each other, negative (variables go opposite ways) Ex: when there is < pay, goods also > Ex: when < alcohol is consumed, fetal alcohol syndrome is < The + or - sign shows the direction, not strength, of correlations. Periods of development are: critical (must occur in this time frame, sensitive (optimal range) Discontinuous change is qualitative (run, run fast, run smart) & quantitative (crawl, walk, run) Processing info is: bottom-up (enviro, neurons, brain) Then: top-down (brain, neurons, reaction to enviro) Goes to olfactory bulb, not thalamus: somatosensory. Nerve endings are hot & cold, pain & temperature. Touch travels from sensory receptors - spinal cord - cross brainstem - thalamus - somatosensory in parietal lobe.
