association
a connection between the representations of two events (two stimuli or a stimulus and a response) such that the occurrence of one of the events activates the representation of the other
dualism
the view of behavior according to which actions can be separated into two categories: voluntary behavior controlled by the mind and involuntary behavior controlled by reflex mechanisms
empiricism
a philosophy according to which all ideas in the mind arise from experience
fatigue
a temporary decrease in behavior caused by repeated or excessive use of the muscles involved in the behavior
hedonism
the philosophy proposed by Hobbes according to which the actions of organisms are determined by the pursuit of pleasure and the avoidance of pain
learning
an enduring change in the mechanisms of behavior involving specific stimuli and/or responses that results from prior experience with similar stimuli and responses
maturation
a change in behavior caused by physical or physiological development of the organism in the absence of experience with particular environmental events
nativism
the philosophical position adopted by pavlov that all behavioral and physiological processes are regulated by the nervous system
nonsense syllable
a three-letter combo (two consonants separated by a vowel) that has no meaning
performance
an organism's activities at a particular time
reflex
a mechanism that enables a specific environmental event to elicit a specific response
primary process
the first process in the opponent process theory of motivation that is elicited by biologically significant events -responsible for the quality of the emotional state that occurs in the presence of the stimulus -"a"
opponent process
causes physiological and behavioral changes that are the opposite of those caused by the primary process -"b"
afferent neuron
a neuron that transmits messages from sense organs to the central nervous system -also called sensory neuron
appetite behavior
behavior that occurs early in a natural behavior sequence and serves to bring the organism in contact with a releasing stimulus
consummatory behavior
behavior that serves to bring a natural sequence of behavior to consummation or completion -usually series-typical modal action patterns
drug tolerance
reduction in the effectiveness of a drug as a result of repeated use of the drug
efferent neuron
a neuron that transmits impulses to muscles -"motor neuron"
focal search mode
the second component of the feeding behavior sequence following general search, in which the organism engages in behavior focused on a particular location/stimulus that is indicative of the presence of food
food handling and ingestion mode
the last component of the feeding behavior sequence, in which the organism engages in nondirected locomotor behavior
habituation effect
a progressive decrease in the vigor of elicited behavior that may occur with repeated presentations of the eliciting stimulus
habituation process
a neural mechanism activated by repetitions of a stimulus that reduces the magnitude of responses elicited by that stimulus
interneuron
a neuron in the spinal cord that transmits impulses from afferent (sensory) to efferent (motor) neurons
modal action pattern
A response pattern exhibited by most, if not all, members of a species, used as basic units of behavior in ethological investigations of behavior
sensitization effect
an increase in the vigor of elicited behavior that may result from repeated presentations of the eliciting stimulus or from exposure to a strong extraneous stimulus
sensitization process
a neural mechanism that increases the magnitude of responses elicited by a stimulus
sensory adaptation
a temporary reduction in the sensitivity of sense organs caused by repeated or excessive stimulus
sign stimulus
a specific feature of an object or animal that elicits a modal action pattern -"releasing stimulus"
spontaneous recorvery
return of responding to baseline levels produced by a period of rest after habituation or sensitization
SR system
the shortest neural pathway that connects the sense organs stimulated by an eliciting stimulus and the muscles involved in making the elicited response
state system
neural structures that determine the general level of responsiveness, or arousal of the organism
supernormal stimulus
a sign stimulus whose features have been artificially enhanced or exaggerated to produce an abnormally large modal action pattern
