IB psych sl

maguire

taxi + posterior hippocampus - behavior/localization of function

draganski

juggling +grey matter in temporal love- neuro plasticity/neural pruning

antonova

game + scopolamine (hippocampus activity)- neurotransmitter/antagonist/agonist/inhibitory synapses

mcgaugh and cahill

family story + propanol (amygdala activity and adrenaline) - horomone behavior

wedekind

t shirt BO + MCH gene compatibility - pheromone/ evolution

kendler

twin depression - gene behavior/ genetic similarities/ kinship

glanzer and cunitz

list and interrupted recall (multi store model) - memory model

brewer and treyens

office - schema

englich and mussweiler

judges (dual process) - model of thinking/ bias

landry and bartling

letter list and voice suppression (working memory model) - model

loftus and palmer

car crash words - reconstructive memory

brown and kulik

mlk vs jfk death flashbulb - emotion effects

drury

vr fire and football fans (social identity) - social identity/ cultural groups

bandura

bobo doll (social cognitive theory) - social cognitive theory

sherif

boy summer camp - social identity theory/ social groups

berry

individual vs community culture - individual and the group/ cultural dimension/ cultural influence behavior

hamilton and gifford

majority vs minority (stereotypes) - formation of stereotypes

martin and halverson

child gender pic - stereotyping on behavior

miranda and mathany

latino acculturation - acculturation/ assimilation

social identity theory

assumption that individuals strive to improve their self-image by trying to enhance self esteem through social identities. social identity is salient. individuals identify themselves with a group in order to preserve ego.

social cognitive theory

assumption that humans learn behavior through observational learning (attention, retention, reproduction, motivation)

stereotype

social perception of an individual based on group membership or physical attributes that are given to all members of that group

cultural dimension

values within a culture that influence behavior and cognition. categorize behavior on a social level of analysis instead of individual. describe behavior of a group.

enculturation

learning and maintenance of behavior and norms of own culture

acculturation

adopting the norms and behaviors of the majority culture (assimilation, integration, separation, marginalization)

multi store model

proposed by atkinson and shittrin. describes memory as a flow of information through sensory registry, STM, LTM. SR (brief) → STM (short duration when rehearsal) → LTM (potentially unlimited duration)

schema

mental frameworks filled with biases due to categorized information. derived from prior experiences and knowledge. more effectively stores information.

dual process model

human thinking and decision making based on system 1 and system 2. system 1 default (intuitive, fast, unconscious) system 2 specific (analytical, slow, conscious)

working memory model

proposed by baddeley and hitch. short term memory composed of central executive (phonological loop [language], visuospatial sketchpad [visual semantics], episodic buffer [STM episodic memory linked to LTM])

anchoring bias

cognitive bias that causes people to rely on first piece of information given on a topic

MRI

3D image of brain structure using magnetic field and radio waves to map brain activity and what tissue is activated.

localization of function

specific parts of the brain have specific functions related to specific behavior. many parts working at the same time.

neurotransmitter

chemicals released into synapse after action potential released. reabsorbed by neuron.

agonist

neurotransmitters for receptor sites. acetylcholine for ACh

antagonist

drugs that block receptor site and block neurotransmitter (no action potential). scopolamine for ACh receptor site

neural network

dendrite branches formed when learning new information. more information increases density

neural pruning

neural branches not stimulated → pruned to make room for new information and new branches. removes unnecessary information

excitatory neurotransmitter

increase likelihood of neuron firing by depolarizing the neuron (acetylcholine)

inhibitory neurotransmitter

decrease likelihood of neuron firing by hyper polarizing the neuron (GABA)

horomone

chemical secreted by gland released into bloodstream. takes longer for behavior changes and last longer (adrenaline, cortisol)

adrenaline

secreted by adrenal gland. responsible for fight or flight. plays role in emotional memory formation.

testosterone

produced by testes. high levels of test more aggression

pheromone

chemical substance produced and released into surrounding environment to signal mating availability. no definite human proof

kinship

type of study regarding influence of genetics and environment. how emotional bonds are formed
