Psychology

the study of the behavior of humans and animals

Behavior

anything that a subject does involving action or stimulation

Theory

the analysis of a set of facts and their relation with one another

Hypothesis

assumption that can be tested

Empirical

observed

Data

measurement/results of experiment

Independent Variable

conditions the researcher decides on; factor

Dependent Variable

what you measure; result

Positive Reinforcer

increases likelihood of a behavior by adding something

Negative Reinforcer

increases likelihood of a behavior by taking something away

Punisher

anything that decreases a behavior

case study

study of a single subject

control subject

don't have IV apply to them

Yoked Control

one subject's behavior will effect another subject's

P-Value

probability that a result will occur at ranom

Inferential

relationship between two variables

Rene Decartes

Dualism-I think therefore I am

Herman von Helmoltz

physiology and psychology, the scientific method, hypothesis testing, nerve impulses and neural communication

William James

functionalism-principles of psychology (1890)- based on natural selection

Sigmund Freud

Intro to Psychoanalysis (1917); neuroses, hypnosis, the unconscious

Ivan Pavlov

conditioned reflex, classical conditioning, behavior modification

John Watson

Behaviorist Manifesto (1913), life and the behavior of living organisms could be explained entirely by chemistry and physics without recourse to a supposed "vital force"; scientific approach: study of the relationship between environmental events and the behavior of the organism

B.F. Skinner

Harvard behaviorist-operant coniditioning chamber (Skinner Box); Experimental Analysis of Behavior

Concept of Neuron

Camillo Golgi and Ramon y Cajal (staining)

Discovery of the first neurotransmitter

Otto Loewi- frog hearts- discovered acetylcholine released from one heart could slow the other heart

Cell Soma

Body of neuron-contains the nucleus

Dendrites

Often concentrated on the cell soma- receive infrmation

Axon

Transports materials and conducts impulse to nerve terminal where transmitter is released

Synapse

structure that permits a neuron to pass an electrical or chemical signal to another cell (neural or otherwise).

Presynaptic neuron

where neurotransmitter is released

Neurotransmitter

stored in synaptic vesicles

Postsynaptic neuron

where neurotransmitter signal is received

Neurotransmitter

Binds to receptors to produce its effects

Action Potential

Dendrites receive incoming signals that produce postsynaptic potentials (ISPs, ESPs)
Potentials build up to a threshold to produce an action potential
Impulse travels down the axon to the nerve terminal to produce neurotransmitter releases

GABA

Major inhibitory transmitter in the brain: ISPs keep brain cells quiet/under control/ at rease

A boost in GABA: Alcohol, sleeping pils , general anesthetics

Glutamate

Major excitatory neurotransmitter in the brain: ESPs
too much glutamate: seizures
not enough: schizophrenia

Dopamine

initiation of voluntary motor sequences; motivated behaviors

Boost: attention/alertness- cocaine, adderall
Not Enough: Parkinson's disease
Block: treatment of scizophrenia

Serotonin

behavioral inhibition
Boost: SSRIs as antidepressants
Low: Migrane
Controls impulsivity

Forebrain, Midbrain, Hindbrain

Major Brain Lobes

Occipital, Parietal, Temporal, Frontal

Forebrain

Cerebrum- sensory, motor, executive functions
Hypothalamus- hormone regulation

The relationship between physical characteristics of stimuli and our perception of those timuli

Grouping

Act of putting objects together in categories to more easily process information based on proximity and similarity

Acquisition

an increase in probability that a conditioned stimulus will illicit a conditioned response

Habituation

Decrease in response to a stimulus after repeated presentations

Extinction

Decrease of a conditioned stimulus over time

Second-Order Conditioning

After original conditioning a second CS follows the first CS many time, eventually the second CS will elicit the same response as the first CS

Passive/Classical Conditioning

Pavlov's Dogs/Little Albert

Operant/Instrumental Conditioning

Reinforce after appropriate response

Law of Effect

Performance is strengthened if it's followed by a reward and weakened if it's not

Garcia Effect

the aversion to a CS can occur after just a single trial and over a large delay

Generalization

A conditioned response can also be elicited by stimuli that is similar to the original conditioned stimulus

Ratio Schedules

Reinforcer is presented after a number of responses
Fixed Ratio- reward for amount of productivity
Variable Ratio- steady rates of behavior over time

Interval Schedules

Reinforcer is presented after behavior is done over time.
Fixed Interval- Measuring interval behavior of reward
Variable Interval- steady intervals of behavior

Encoding

Entering Items into Memory

Storage

Retaining Items in memory

Retrieval

Recovering items from memory

Sensory Memory

Large Capacity from 0.5 seconds (iconic) to 2-3 seconds (echoic). Briefly stores impressions so they overlap and appear continuous.

Short Term Memory

2-7 Memories from 30 seconds. Temporary storage for information in use; "working memory"

Long Term Memory

Limitless capacity; stores huge quantities of information, experiences and skills

Procedural Memory

Sleep Stages

Stages 1, 2, 3 and REM

Stage 1 Sleep

beginning of sleep- THETA

Stage 2 Sleep

similar to and just after REM- dreaming is rare

Stage 3 Sleep
