Flashcards in Chapter 4,5,6 Vocab Deck (294)
The fact that rats rarely venture away from the walls of the test chamber and rarely engage in such activities as rearing or grooming. (fearful rats become this)
The major psychoactive ingredient of tobacco
Typical patterns of aggression and defensive behavior can be observed and measured during combative encounters between the dominant rat of an established colony and a smaller male intruder.
A poisonous substance found in some mushrooms
Elevated Plus Maze
Four armed, plus-sign shaped maze that is a test of defensiveness that is commonly used to study in rats anxiolytic (anxiety-reducing) effects of drugs. Two arms have sides and two do not.
A receptor blocker that exerts an antagonistic effect at muscarinic receptors
Posture when a female is sexually receptive
An extract of a certain class of woody vines
When a male rat inserts his penis
Blocks the release of acetylcholine at neuromuscular junctions and is used cosmetically to treat wrinkles
Ejects his sperm
The gray matter around the cerebral aqueduct, which contains opiate receptors and activates a descending analgesia circuit
Proportion of mounts that elicit lordosis
Naturally occurring in the body
Pavlovian Conditioning Paradigm
Experimenter pairs an initially neutral stimulus, conditional stimulus, with an unconditioned stimulus?a stimulus that elicits an unconditional response. As a result of these pairings, the conditioned stimulus can elicit a conditional response
The first class of endogenous opiods to be discovered
Operant Conditioning Paradigm
The rate at which a particular voluntary response is emitted is increased by reinforcement or decreased by punishment.
A class of endogenous opiods
Animals press a lever to deliver electrical stimulation to particular sites in their own brains
Parts of the brain that support self-stimulation
Conditioned Taste Aversion
Avoidance response that develops to tastes of food whose consumption has been followed by illness
Afraid of new things
A term that indicates the closeness in time of two or more events. The temporal contiguity of events is important in learning.
Principle of Equipotentiality
The view that conditioning proceeds in basically the same manner regardless of the particular stimuli and responses under investigation.
Radial Arm Maze
An array of arms, usually eight arms, radiating from a central starting area. At the end of each arm is a food cup, which may or may not be baited(have food), depending on the purpose of the study.
Morris Water Maze
Rats are placed in a circular, featureless pool of cool, milky water, in which they must swim until they discover the escape platform. The rats learn to swim directly to the platform by using spatial cues.
Conditioned Defensive Burying
When rats receive a single aversive object mounted on the wall and the rats respond by flinging bedding material at it.
Billionths of a meter
Too long for humans to see
