GABA - ✔️✔️chemical involved in inhibiting neural activity. inhibitory transmitter (slows
you down). too little --> anxiety
Dark adaptation - ✔️✔️the process by which our eyes adjust to darkness after being
exposed to light
Absolute threshold - ✔️✔️the intensity amount which is needed to detect the difference
between nothing and something (it is the lowest level at which an individual can
experience a sensation)
Acetylcholine - ✔️✔️chemical involved in memory. too little --> Alzheimer's
All or none principle - ✔️✔️the neuron either fires at full strength or not at all
Amygdala - ✔️✔️(limbic system) involved in fear responses and memory of fear
Autonomic nervous system - ✔️✔️(PNS)controls organs, glands, and involuntary
muscles
Axon - ✔️✔️transmits signal away from cell
Behaviorism - ✔️✔️John Watson-the study of behavior
Binocular cues - ✔️✔️using cues from both eyes to determine depth perception
Binocular disparity - ✔️✔️difference in images between two eyes
Biological perspective - ✔️✔️human and animal behavior is seen as a direct result of
events in the body
Blind spot - ✔️✔️where the optic nerve leaves the eye (no photoreceptor cells)
Broca's aphasia - ✔️✔️trouble producing language
Case study - ✔️✔️an in-depth report about the details of a specific case (single
participant)
Cerebellum - ✔️✔️(hindbrain) controls all involuntary, rapid, fine motor movement
Closure - ✔️✔️(Gestalt laws of grouping) completing figures
, Color blindness - ✔️✔️cause is the amount of pigment per cone is reduced or absent
Cones - ✔️✔️color vision and sharpness of vision
Continuity - ✔️✔️(Gestalt laws of grouping) we assume there is a continuous line
Control group - ✔️✔️similar subjects who don't receive special treatment
Cornea - ✔️✔️outer covering of the eye
Correlation - ✔️✔️prediction- takes a direction and has a magnitude (1 to -1)
Correlational coefficient - ✔️✔️numerical index of degree of relationship
Dendrite - ✔️✔️receives signals
Dependent variable - ✔️✔️variable affected by manipulation
Dopamine - ✔️✔️chemical involved in cognitive and motor control. too much -->
schizophrenia, too little --> Parkinson's disease
Double blind study - ✔️✔️neither the participants or experimenter knows the exact
treatment
Endorphins - ✔️✔️chemical involved in emotional behaviors (anxiety, fear)
Evolutionary perspective - ✔️✔️focuses on the biological bases for universal mental
characteristics that all humans share (seeks to explain general mental strategies and
traits)
Experiment - ✔️✔️manipulation of one variable under controlled conditions so that
resulting changes in another variable can be observed
Experimental group - ✔️✔️subjects who receive some special treatment in regard to
the independent variable
Experimenter bias - ✔️✔️where the scientists performing the research influence the
results, in order to portray a certain outcome.
Forea - ✔️✔️greatest concentration of photoreceptors
Forebrain - ✔️✔️emotion, complex thought
