an integrated approach that incorporates bio logical, psychological, and social cultural levels of analysis
hindsight bias
The tendency to believe, after learning an outcome, that one would have foreseen it.
placebo effect
experimental results caused by expectations alone; any effect of behavior caused by the administration of an intern substance or condition, which the recipient assumes is an active agent
case study

naturalistic observation
observing and recording behavior in naturally occurring situations without trying to manipulate or control the situation

plasticity
brains ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
phrenology
The study of bumps on the scull
axon
The extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands
dendrite
The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
frontal lobe
portion of the cerebral cortex lying just behind the four head; involved in speaking and muscle movements and in making plans and judgments
Occipital lobe
portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields
cocktail party effect
we can only truly concentrate on one voice in a crowd

we only see what we’d like to see
selective attention
The focusing on conscious awareness on a particular stimulus

narcolepsy
A sleep disorder characterized by uncontrollable sleep attacks.
melatonin

sleep deprivation
symptoms include irritability fatigue memory loss increase of appetite
biological versus adoptive influences
biological influences shaped our personality and physical appearances. Adopted influences our children’s attitudes, values, manners, faith, and politics
natural selection
The principle that among the range of inherited traits variations, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations
behavior genetics
The study of the relative power and limits of genetic and environmental influences on our behavior
chromosomes
threadlike structures made of DNA molecules that contain the genes
DNA
A complex molecule containing the genetic information that makes up chromosomes
identical twins
twins who develop from a single fertilized egg that splits into two, creating two genetically identical organisms
fraternal twins
twins who develop from separate fertilized eggs. They are genetically no closer than Brothers and sisters, but they share a fetal environment
embryo
The developing human organism from about two weeks after fertilization through the second month
piaget’s theory of cognitive development
from birth to nearly 2 years – sensorimotor: experiencing the world through senses and actions involves object permeance and stranger anxiety.
Two to about six or seven years – preoperational: representing things with words and images using intuitive rather than logical reasoning. Pretend play and egocentrism
about 7 to 11 years-concrete operational: thinking logically about concrete events grasping concrete analogies and performing arithmetic operations. Conversion and mathematical transformations appear
about 12 through adulthood-formal operational: abstract reasoning. potential for mature moral reasoning
Harlows attachment theory
infants need attachment from their parents. Touching is soothing to the child and is needed for healthy relationship
object permanence
The awareness that things continue to exist even when not perceived
theory of mind
peoples ideas about their own and others’ mental states. how they perceive their feelings, perceptions, and thoughts, and the behaviors these might predict
critical period
in optimal period Shortly after birth wear an organisms exposure to certain stimuli or experiences produces proper development
