experiments

helping individuals adapt to their environment.
TERM 4
Psychodynamic
DEFINITION 4
Freud *behavior reflects interplay between thoughts,
feelings, wishes *some are unconscious *processes may
conflict with each other --Therapist interpret motives, and
unearth unconscious processes --Falsifiability criterion-theory
cannot be tested and proven incorrect
TERM 5
Behaviorist
DEFINITION 5
Pavlov, Watson, Skinner *Controlled by objects and events in
the environment *Thoughts and feelings NOT involved
Cognitive
way people perceive, process and retrieve info (memory and
decision making) -Info processing-how we take input from
environment and transform it into meaningful output
TERM 7
Evolutionary
DEFINITION 7
Darwin -behavior must be understood in terms of
evolutionary and adaptive significance -nature vs. nurture
TERM 8
Variable
DEFINITION 8
phenomenon that changes across situations or varies among
individuals
TERM 9
Continuous Variable
DEFINITION 9
ranges from high to low (GPA)
TERM 10
Categorical Variable
DEFINITION 10
groupings or classifications --Male/Female, Yes/No
Predictive
measure predicts performance or scores future measures
TERM 17
multi-modal assessment
DEFINITION 17
using multiple measures of a construct
TERM 18
Experimental
Research
DEFINITION 18
research method that can establish causation
TERM 19
Independent Variable
DEFINITION 19
variable that the experiment manipulates (the conditions)
TERM 20
Dependent Variable
DEFINITION 20
variable examined to see how/if its influenced by the
independent
Condition
experimental--study group being tested -control--study group
that receives neutral treatment
TERM 22
Confounding Variable
DEFINITION 22
variable that interferes with relationship of IV and DV--timing,
external, characteristics
TERM 23
Inferential Stats
DEFINITION 23
Analyses that determine whether hypothesis is correct (hope
for possibility of .05 or less)
TERM 24
Correlational
Research
DEFINITION 24
research that assesses the degree to which two variables are
related
TERM 25
Correlational Coefficient
DEFINITION 25
index of extent to which 2 variables are related
Axon
extension from cell body of neuron- electrical impulses pass
myelin sheath-lipid protective coating of axons involved in
diseases such as MS
TERM 32
Terminal Button
DEFINITION 32
end of axon sends signals from neuron to adjacent cells
(contains neurotransmitters - NT)
TERM 33
Synapses
DEFINITION 33
space between neurons NTs pass/communicate with other
neurons
TERM 34
Resting Potential
DEFINITION 34
neuron at rest, not firing, negatively charged
TERM 35
Graded potential
DEFINITION 35
neuron stimulated by another causing voltage changes down
the axon
action potential
voltage changes-lead to positive charge-causes neuron to
fire -causes NT to release into "synaptic cleft" in between
neurons
TERM 37
Excitatory
DEFINITION 37
makes another action potential/firing likely
TERM 38
Inhibitory
DEFINITION 38
reduces likelihood of another cycle
TERM 39

DEFINITION 39
excitatory NT involves in widespread activity (MSG, Learning)
TERM 40

DEFINITION 40
Inhibitory NT -involved in anxiety regulation slows things
down

TERM 49
Somatic NS
DEFINITION 49
delivers sensory info to CNS--receptors throughout body -
carry out motor commands of CNS (fire alarm)
TERM 50
Automatic NS
DEFINITION 50
conveys info between CNS and bodily structures that carry
out life processes
Parasympathetic
Controls "normal" bodily activity
TERM 52
Sympathetic
