Control group | Group that is not exposed to the treatment (contrasts with the experimental group and serves as a comparison for evaluation effect of treatment) |
Double-blind procedure | An experimental procedure where both the research participants and the research staff are ignorant about whether participants have received treatment or a placebo |
Placebo effect | Any effect on behavior caused by administration of inert substance or condition, which the recipient assumes is an active agent. |

Biological Psychology | Scientific study of the links between biological and psychological processes. |
Neuron | A nerve cell; basic building block of the nervous system |
Dendrite | Neuron's bushy, branching extensions that receive messages and conduct impulses toward a cell body |
Axon | Neuron's extension that passes messages through its branching terminal fibers (forms junctions with other neurons, muscles, or glands) |
Action potential | A neural impulse; brief electrical charge that travels down an axon |
Threshold | Level of stimulation required to trigger a neural impulse |
Synapse | The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron |
Neurotransmitters | Chemical messengers that cross the synaptic clefts between neurons. Travel across and bind to receptor sites on the receiving neuron influencing whether neuron will generate neural impulse |
Endorphins | Natural, opiatelike neurotransmitters linked to pain control and to pleasure |
Nervous System | Speedy, electrochemical communication network consisting of all the nerve cells of the peripheral and central nervous systems |
Central Nervous System | Consists of the brain and spinal cord |
Peripheral Nervous System | Sensory and motor neurons that connect the central nervous system to the rest of the body |
Nerves | Bundled axons that form neural "cables" connecting the CNS with muscles, glands, and other sense organs |
Sensory Neurons | Neurons that carry incoming information from the sensory receptors to the brain and spinal cord |
Motor Neurons | Neurons that carry outgoing information from the brain and spinal cord to the muscles and glands |
Interneurons | Neurons in the brain and spinal cord that communicate internally and intervene between sensory and motor inputs |
Somatic Nervous System | Division of the peripheral nervous system that controls the body's skeletal muscles (skeletal nervous system) |
Autonomic Nervous System | Part of the peripheral nervous system that controls the glands and muscles of the internal organs |
Sympathetic Nervous System | Division of the autonomic nervous system that arouses the body (fight or flight) mobilizing energy in stressful situations |
Parasympathetic Nervous System | Division of the autonomic nervous system that calms the body and conserves energy (rest and recover) |
Reflex | A simple, automatic response to a sensory stimulus |
Endocrine System | "Slow" chemical communication system; a set of glands that secrete hormones into the bloodstream |
Hormones | Chemical messengers that are manufactured by the endocrine glands and travel through the bloodstream; affect other tissues |
Adrenal glands | Pair of endocrine glands that sit on top of the kidneys and secrete hormones (epinephrine and norepinehrine) that help arouse the body in times of stress |
