Cards

Term
obersvational learning
Definition
ex. Bandura's Bobo Doll- Vicarious reinforcement-ex2.lab raised monkey's vs. wild monkeys-tendency toward believing an authority or popular figure
Term
social cognitivist (cognitive theory)
Definition
learning is a measurable behavior-ppl learn from one another by modeling/imitating
Term
Experiments
Definition
Pavlovs-Dogs
Pfungst-Hans the Clever Horse
Little Albert-Conditioning of Fear
Thorndikes-Puzzlebox
Skinner- Box experiment
Bandura- Bobo Doll
Term
classical V. Operant
Definition
Classic- Bell/ learned association btwn one stim UCS and aonther CS - organism is passive - involuntary reflex

Operant-Beep/ learned association btwn behavior and a consequence-organism is active-voluntary behavior
Term
Law of effect
Definition
behavior changes because of its consequences
Term
determinism
Definition
with knowledge of the past, present, environment and energetic disposition we can conclude that the thoughts, beliefs and emotions are because of our environment
Term
controlling/changing behavior
Definition
-scientific method
-find correlations
-use info/ test hypothesis
-conclude what needs to be changed or controlled
Term
Predicting Behavior
Definition
correlational methods->relationship btwn 2 methods

Correlation does not equal causation..ex, class attendance and grade

3rd Variable Problem- Something other than the two variables accounts for the relationship

Reverse Casuality-cannot determine which variable cause what
Term
3 Descriptive Research Methods
Definition
Case Study
-too narrow->cant determine effect

Naturalistic Observation
P->difft times /samplings
C-> cant control variables/ dtermin cause and efffect

Survey Research
P-Large Groug\p/ easy convenient
C-dishonesty/bias
Term
4 goals of Psychology
Definition
Describe-Predict-Explain-Control/Change
Term
hippocampus
Definition
spatial memory
Term
Thalamus
Definition
Sensory and motor relay station
Term
Hypothalumus and Limbic System
Definition
involved in motivation/emotions
Term
classical conditioning/conditioned stimulus
Definition
ex--> after many mornings of drinking coffee, just the smell of coffe can wake you up
Term
Nativism
Definition
The view that elementary ideas are innate to the human mind and are not gained through experience
Term
Variability
Definition
The standard dev. of the mean/medium
Term
Dendrites vs. axon Terminals
Definition
Dendrites->Part of the nueron specialized to recieve signals from other nuerons

Axon Terminals-->send signals to other nuerons
Term
Gestalt
Definition
The whole is greater than the sum of its parts
Term
Lateral Inhibition
Definition
-heightens the perceived contrast in lightness at contours

-allows us to see shape
Term
cones vs. rods
Definition
cones-> color vision/ acuity BRIGHT LIGHT

rods-> vision DIM LIGHT

+neural convergence helps explain the greater sensitivity and lower acuity of rod vision compared to cone vision
Term
left brain vs right brain
Definition
left--> Language(Interprets behavior)

Right-->Visuospatial taks
Term
corpus callosum
Definition
-connects 2 hemispheres

-is a massive bundles of axons
Term
Testing Brain behavioral Function
Definition
TMS-disrupts/triggers activity in specific cortical areas by magnetic field

EEg-records electrical activity in the brain via electrodes

PET/FMRI-produce images that show changes in activity in the brain by measuring blood flow
Term
operant conditioning
Definition
reflects the impact of an action's consequences on it's recurrance
(shaping occurs when successive approximation to the desired response are enforced)

*Reinforcement increases increases response rate..punishment decreases response rate.

-reward increases rate of operant conditioning
Term
Positive/Negative Reinforcement
Definition
positive->praise is given

negative->pain goes away
Term
positive/ negative Punishment
Definition
positive->a reprimandi is given

negative->privileges are taken away
Term
Behaviorism
Definition
only deals w/observable behavior/ events not the mind
Term
Classical Conditioning (Pavlovs Dogs)
Definition
(the process involved in learning new reflex)

1. unconditioned reflex-food-->salivation
2 nuetral stim--> is added (bell) before the unconditional stim (food)

3 After pairing food w/bell->produce a conditional response eventually bell-->salivation
Term
inferential statistics
Definition
helps us asses the likelihood that relationships are observed are real/ repeatable or due to chance

significant not equal due to change of statistics
Term
Correlation does not equal...
Definition
CAUSATION
Term
Descriptive Studies
Definition
designed only to characterize/record what is observed

NOT..to test hypothesis about variable relationships
Term
independent variable vs. dependent variable
Definition
IDV- the one being manipulated
...>while looking for corresponding differences in the DV-> the variable being affected
Term
Wernicke's Aphasia Vs. Broca's Aphasia
Definition
Wernicke's->impaired language comprehension--fluent but meaningless speech

Broca's-> clear meaning but grammatical purposes are missing
Term
Parts of the Brain (your dooome)
Definition
4 lobes POT F -corpus collosum-hippocampus-amygdala-hypothalamus-thalamus-medulla/pons-cerebellum
Term
split brain
Definition
corpus collosum is cut... flash of word+ right brain processes

-Language (left) side didn't process signal from the right so he could not articulate the word, just interpret his drawing of the word
Term
4 lobes
Definition
occipital-primary visual cortex (color and shape)

temporal-auditory cortex/ hearing
-memory/understanding meanings

Parietal- Sensory Organs

Frontal-PLanning and reasoning and deciding
-Judgement, balance,emotion
-inhibition
