Evolutionary School of Psychology
theoretical approach to psychology that attempts to explain mental and psychological traits—such as memory, perception, or language—as adaptations, i.e., as the functional products of natural selection or sexual selection.
Cognitive School of Psychology
Focuses on the important role of mental processes in how people process information, develop language, solve problems and think. Interested in how people understand, diagnose, and solve problems
Clinical Psychologist
assess and treat mental, emotional, and behavioral disorders. These range from short-term crises, such as difficulties resulting from adolescent rebellion, to more severe, chronic conditions such as schizophrenia.

explore the relationships between brain systems and behavior. EX: may study the way the brain creates and stores memories, or how various diseases and injuries of the brain affect emotion, perception, and behavior.
Quantitative and measurement psychologist
focus on methods and techniques for designing experiments and analyzing psychological data. They develop and evaluate mathematical models for psychological tests, among many other things
School Psychologist
work directly with public and private schools. They assess and counsel students, consult with parents and school staff, and conduct behavioral interventions when appropriate. Most school districts employ psychologists full time

psychiatrist
they can prescribe drugs unlike psychologists. Begin their careers in medical school, unlike psychologists that get bachelors in psychology. After earning their MD, they go on to four years of residency training in mental health
basic research
has as its objective the advancement of knowledge. It is exploratory and often driven by the researcher's curiosity, interest, and intuition. It is conducted without any practical end in mind, though it may later have an application

experimental method
the manipulation of an IV to understand its effect on a DV; Identifies Cause-effect
Control Condition
The condition of an experiment that contrasts with the experimental condition and serves as a comparison for evaluating the effect of the treatment.
Experimental Condition
The condition of an experiment that exposes participants to the treatment, that is, to one version of the independent variable.
independent variable
the factor in an experiment that is manipulated by the experimenter and is given to the experimental group. It's the one thing that is different between the experimental group and the control group.
Dependent Variable
The outcome factor; the variable may change in response to manipulations of the independent variable.
Confounding Variable
any possible variable- other than the IV - that may cause the observed effect; thus making it impossible to determine the actual cause of the change in the DV.
Random assignment
random placement of subjects into experimental or control groups;
within-group design
A _____ study is an experiment where all subjects test (and respond to) all treatment combinations. _____ design is the opposite of a between-subjects design.
between-subjects design
each participant participates in one and only one group. The results from each group are then compared to each other to examine differences, and thus, effect of the IV.
single blind
Term used to described a study in which either the investigator or the participant, but not both of them, is unaware of the nature of the treatment the participant is receiving. Also called single-masked
double blind study
a study in which both the investigator or the participant are blind to (unaware of) the nature of the treatment the participant is receiving. Prevents expectations of researcher or participant from influencing results
Experimenter Bias
the phenomenon in experimental science by which the outcome of an experiment tends to be biased towards a result expected by the human experimenter.
placebo

placebo effect
The beneficial effect in a patient following a particular treatment that arises from the patient's expectations concerning the treatment rather than from the treatment itself.
meta-analyses
The process or technique of synthesizing research results by using various statistical methods to retrieve, select, and combine results from previous separate but related studies
variance
The square of the standard deviation. Whereas the mean is a way to describe the location of a distribution, this is a way to capture its scale or degree of being spread out.
Standard Deviation
a measure of variation (or variability) that indicates the typical distance between the scores of a distribution and the mean.
Statistical Significance
A statistical statement of how likely it is that an obtained result occurred by chance. Numerically, 5% or (.05) is generally considered the cutoff.
three measures of central tendency
mean, mode, and the median. These measures tend to tell us something about the "center" of a set of statistics. On a curve of normal distribution, they all fall on the same point.
mode
most frequently occurring event
mean
average
median
midpoint
Operational Definition
A statement of the procedures (operations) used to define research variables.

biological psychology
a branch of psychology concerned with the links between biology and behavior. (Some biological psychologists call themselves neuroscientists, neuropsychologists, behavior geneticists, physiological psychologists, or biopsychologists.)
neuron
a nerve cell; the basic building block of the nervous system.
soma (AKA "cell body", "cyton")
the part of the neuron that contains cytoplasm and the nucleus, which directs synthesis of such substances as NTs
dendrite
branch-like structures on neurons that receive messages from the axons of other neurons and transmit them towards the cell body. Each neuron may have thousands of these structures.
axon
the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands.
myelin sheath
a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next.
action potential
a neural impulse; a brief electrical charge that travels down an axon. The action potential is generated by the movement of positively charged atoms in and out of channels in the axon's membrane.
threshold
the level of stimulation required to trigger a neural impulse.
synapse
the junction between the axon top of the sending neuron and the dendrite of cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft.
neurotransmitters
chemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, they travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
acetylcholine (ACh)
a neurotransmitter that enables learning and memory and also triggers muscle contraction.
endorphins
"morphine within" natural, opiate-like neurotransmitters linked to pain control and to pleasure.
Norepinephrine (AKA "noradrenaline")
Involved in making us feel alert (increases heartbeat and arousal); Also involved in learning and memory retrieval; EX: NE activates your bodies emergency response (heart rate up, sweat, blood pressure up)
Serotonin
Natural tranquilizer (deep dreamless sleep, reduces hunger, makes you calm, reduces pain); Also associated with moods and emotional states: Depression; We naturally get _____ from L-Tryptophan in our diet (ex: turkey)
GABA (gamma-aminobutyric acid)
Controls anxiety; Also involved in the area of our brain that controls daily sleep and wake cycles; EX: Most sedatives or tranquilizers (Valium and Xanax) increase _____, alcohol also increases; Overdose of this shuts down breathing
Dopamine
Important for movement control, attention, learning and pleasure/rewarding sensations; a deficiency is associated with Parkinson's disease, an excess may be associated with schizophrenia
nerves
neural "cables" containing many axons. These bundled axons, which are part of the peripheral nervous system, connect the central nervous system with muscles, glands, and sense organs.
sensory neurons

motor neurons
neurons that carry outgoing information from the central nervous system to the muscles and glands.
interneurons
central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs.
