AP Psychology Exam Review - Units 0-5
The tendency to believe, after hearing about
Hindsight Bias research findings, that one would have foreseen
it ('I knew it all along' phenomenon).
Directly observable and measurable descriptions
Operational Definitions of variables used in research to allow for
replication.
The process of assigning participants to
experimental and control groups by chance,
Random Assignment
thus minimizing preexisting differences between
those groups.
A computed measure of how much scores vary
Standard Deviation around the mean score; the square root of the
variance.
A statistic that provides the probability that the
difference between groups is due to chance; in
P-value
psychology, a value of .05 or less is considered
statistically significant.
Chemical messengers that traverse the synaptic
Neurotransmitters gaps between neurons, binding to receptor sites
on the receiving neuron.
The law that the neuron either fires at $100\%$
All-or-None Principle or not at all; there is no such thing as a 'weak' or
'strong' action potential.
The division of the autonomic nervous system
Sympathetic Nervous System that arouses the body, mobilizing its energy in
stressful situations (fight-or-flight).
The intricate fabric of interconnected neural cells
covering the cerebral hemispheres; the body's
Cerebral Cortex
ultimate control and information-processing
center.
The brain's ability to change, especially during
Neuroplasticity childhood, by reorganizing after damage or by
building new pathways based on experience.
