Terms Definitions
An interdisciplinary field that combines the work of psychologists, biologists, biochemists, medical researchers, and others in the study of the structure and function of the nervous system.
The process by which neurotransmitters are taken from the synaptic cleft back into the axon terminal for later use, thus terminating their excitatory or inhibitory effect on the receiving neuron.
scientific method
The orderly, systematic procedures that researchers follow as they identify a research problem, design a study to investigate the problem, collect and analyze data, draw conclusions, and communicate their findings.
the slender, tail-like extension of the neuron that transmits signals to the dendrites or cell body of other neurons and to muscles, glands, and other parts of the body.
The endocrine gland responsible for regulating the amount of sugar in the bloodstream.
A neurotransmitter that affects the metabolism of glucose and nutrient energy stored in muscles to be released during strenuous exercise.
Survey, Question, Read, Recite, Review
A testable prediction about the conditions under which a particular behavior or mental process may occur
selection bias
The assignment of participants to experimental or control groups in such a way that systematic differences among the groups are present at the beginning of the experiment.
The scientific stoudy of behavior and mental processes.
The entire group of interest to researchers, to which they wish to generalize their findings; the group from which a sample is selected.
laboratory observation
A descriptive research method in which behavior is studied in a laboratory setting.
naturalistic observation
A descriptive research method in which researchers observe and record behavior in its natural setting, without attempting to influence or control it.
protein molecules on the surfaces of dendrites and cell bodies that have distinct shapes and will interact only with specific neurotransmitters.
The capability of being penetrated or passed through.
parathyroid glands
The endocrine glands that produce PTH, a hormone that helps the body absorb minerals from the diet.
The structure that begins at the point where the spinal cord enlarges as it enters the brain and handles functions critical to physical survival. It includes the medulla, the pons, and the reticular formation.
Research conducted to seek new knowledge and to explore and advance general scientific understanding
A part of a population that is studied to reach conclusions about the entire population.
Any condtion or factor that can be manipulated, controlled, or measured.
dependent variable
The factor or condition that is measured at the end of an experiment and is presumed to vary as a result of the manipulations of the indpendent variable(s).
biological psychology
The school of psychology that looks for links between specific behaviors and equally specific biological processes that often help explain individual differences.
double-blind technique
A procedure in which neither the participant nor the experimenter knows who is in the experimental and control groups until after the data have been gathered; a control for experimental bias.
The most comman cause of damage to adult brains, arising when blockage of an artery cuts off the blood supply to a particular area of the brain or when a blood vessel bursts.
Wernicke's cortex
The language area in the left temporal lobe involved in comprehending the spoken word and in formulating coherent speech and written language.
A small wire used to monitor the electrical activity of or simulate activity within a single neuron.
substantia nigra
The structure in the midbrain that controls unconscious motor movements.
frontal lobes
The largest of the brain's lobes, which contains the motor cortex, Broca's area, and the frontal association areas.
adrenal glands
A pair of endocrine glands that release hormones that prepare the body for emrgencies and stressful situations and also release corticoids and small amounts of the sex hormones.
General points of view used for explaining people's behavior and thinking, whether normal or abnormal
experimental sample
The only research method that can be used to identify cause-effect relationships between two or more conditions or variables.
peripheral nervous system (PNS)
