psych test 1

operational definition

a statement of the procedures used to define research variables

replication

confirms a study by repeating it

descriptive studies

systematic opservations of people, goal is to provide a clear, accurate picture of peoples behavio, thoughts, and attributes. case study, naturalistic observation, survey and interview

correlational studies

look at two numeric variables that are erlated to eachother. correlation coefficient measures how closely two factors vary together

experiment studies

researches study effects by changing one thing. double blind, placebo, randam assignment.

case study

study one person in depth, provides ideas, results and conclusions cant be generalized

theory

combo of findings from studies, or an explanation using integrated set of principles that organize observations and predict behavior

hindsight bias

knew it all along, intuitionkind of thing

scientific method

observation, question, research hypotheses, experiment, collect data, analysis, conclusion, share it

hypothesis

A testable prediction, often implied by a theory

naturalistic observation

record behavior in natural environment, describes but doesnt explain behavior

survey and interview

examin many cases in less depth, but wording effect.

brain

gooey, 2% of body weight, 20% of energy

peripheral nervous system

autonomic vs somatic

central nerve system

-brain, spinal cord
-center of consciousness

autonomic

controls self regulated action of internal orans and glands, sympathetic arousing and parasympathetic calimg

somatic

sensory inut and motor output

corpus callosum

does nothing, connects two hemispheres

brainstem

most buried part of the brain. thalamus, pons, then medulla, controls baisc bodily functions

medulla

base, heartbeat and breathing

pons

coordinate movement, automatic moevemtn

thalamus

directs sensory messages to crotex and transmits replies to cerebellum and medulla. influences multitasking

reticular formation

nerve network running through brainstem and thalamus. involeved i controlling arousal.

cerebellum

baby brain. subconcious stuff, aids in judgement of time and sound and texture discrimination. coordinates coluntary movement and life sustaining functions. helps process and store information outside of awareness.

limbic system

middle of brain (hypothalamus, amygdala, pituitary glad, thalamus, hippocampus, thalamus). hormones, emotions, memoty, some behavior, smell, some speech

amygdala

two lima bean clusters. emltions, more ersponsibe to fear and anxiety. social info

hypothalamus

neural structure lying below thalamus. controls release of hormones throughout body. directs several maintanence activities bia hormones. helps govern endocrine system via pituitary. linked to emotion and reward.

hippocampus

process concious explicit memores. influential in learning. think inside out.

cerebral cortex

evolutionarily newest part of the brain. Brain is identical on both sides of the brain

frontal lobe

personality! conciousness, ecplciit memories. takes in outside siruation and tells everything what to do. control centerl. language too.

parietal lobe

somatosensory cortex, recieves messages from skin receptors (touch temperature, movement, spatial reasoning

occipital lobe

eyes

temporal lobe

ears

corpus collosum

neural fibers that connects left and right

left

speech and math

right

analysis and spacial vizualisation

fmri

measure blood flow ot briaing region by comapring mri scans continuously

mri

sit or lie down in chamber that uses magnetic fields and radio waves to provide a map of brain structure

pet

tracks where in the brain a temp radioactive form of glucose goes while a person given it performs a task

meg

a head coil records magnetic fields from the brain's natural electrical currents

eeg

electrodes placed on the scalp measure electrical activity in neurons

evolutionaty psychology

study of evolution behavior and mind using principles of natural selection

natural selection

you know it

Nature vs. Nurture

which is more influential on development? gentic influence or environment

twin studies

useful in determining stuff. seperated twins.

adoption

people more similar to bio parents than adopted parents

riddle

14% of college students, 15% of summer camp
