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

one subject's behavior will effect another subject's
P-Value

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

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
