Cards

Term
General Search Mode
Definition
the earliest component of the feeding sequence, in which the organism engages in non-directed locomotor behavior
-Form of appetitive behavior
Term
Focal Search Mode
Definition
the second component of the feeding behavior sequence following general search, in which organisms engage in behavior focused on a particular location or stimulus that is indicative of the presence of food
Term
Food Handling Mode
Definition
the last component of the feeding behavior sequence, in which the organism handles and consumes the food
-Similar to consummatory behavior
Term
Habitual Effect
Definition
a progressive decrease in the vigor of elicited behavior that may occur with repeated presentations of the eliciting stimulus
Term
Habituation Process
Definition
a neural mechanism activated by repetitions of a stimulus that reduces the magnitude of responses elicited by that stimulus
Term
Interneuron
Definition
a neuron in the spinal cord that transmits impulses from afferent (sensory) neurons to efferent (motor) neurons
Term
Modal Action Pattern (MAP)
Definition
a response pattern exhibited by most, if not all, members of a species in much the same way.
-used as basic units of behavior in ethological investigations of behavior
Term
Reflex Arc
Definition
neural structures consisting of the afferent (sensory) neurons, interneuron, and efferent (motor) neuron, that enable a stimulus to elicit a reflex response
Term
Sensitization Effect
Definition
an increase in the vigor of elicited behavior that may result from repeated presentations of the eliciting stimulus or from exposure to strong extraneous stimulus
Term
Sensitization Process
Definition
a neural mechanism that increases the magnitude of responses elicited by a stimulus
Term
Sensory Adaptation
Definition
a temporary reduction in the sensitivity of sense organs caused by repeated or excessive stimulation
Term
Sign Stimulus
Definition
a specific feature of an object or animal that elicits a modal action pattern in another organism

aka- releasing stimulus
Term
Spontaneous Recovery
Definition
recovery of a response produced by a period of rest after habituation or extinction
Term
S-R System
Definition
the shortest neural pathway that connects the sense organs stimulated by an eliciting stimulus and the muscles involved in making the elicited response
Term
State System
Definition
neural structures that determine the general level of responsiveness of the organism
Term
Supernormal Stimulus
Definition
an artificially enlarged or exaggerated sign stimulus that elicits an unusually vigorous response
Term
Nativism
Definition
a philosophy according to which human beings are born with innate ideas
Term
Empiricism
Definition
a philosophy according to which all ideas in the mind arise from experience
Term
Appetitive Behavior
Definition
behavior that occurs early in a natural behavior sequence and serves to bring the organism in contact with a releasing stimulus
Term
Procedural Learning
Definition
Learning ways of doing things rather than learning about specific events. Procedural learning is typically not governed by conscious controlled processes
Term
Learning
Definition
an enduring change in the mechanisms of behavior involving specific stimuli and/or responses that results from previous experience with similar stimuli and responses
Term
Declarative or Episodic Learning
Definition
Learning about a specific event or fact, usually accessible to conciousness
Term
Association
Definition
a connection or linkage between the representations of two events (two stimuli or a stimulus and a response) so that the occurrence of one of the events activates the representation of the other
Term
Dualism
Definition
the view of behavior according to which actions can be seperated into two categories: voluntary behavior controlled by the mind, and involuntary behavior controlled by reflex mechanisms
Term
Fatigue
Definition
a temporary decrease in behavior caused by repeated or excessive use of the muscles involved in the behavior
Term
Hedonism
Definition
the philosophy proposed by Hobbes according to which the actions of organisms are determined entirely by the pursuit of pleasure and the avoidance of pain
Term
Maturation
Definition
a change in behavior caused by physical or physiological development of the organism in the absence of experience with particular environmental events
Term
Nervism
Definition
the philosophical position adopted by Pavlov that all behavioral and physiological processes are regulated by the nervous system
Term
Nonsense Syllable
Definition
a three-letter combination (two consonants seperated by a vowel) that has no meaning
Term
Performance
Definition
an organism's activities at a particular time
Term
Reflex
Definition
a mechanism that enables a specific environmental event to elicit a specific response
Term
A Process/ Primary Process
Definition
the first process that is elicited by a biologically significant stimulus
Term
Afferent Neuron
Definition
a neuron that transmits messages from sense organs to the central nervous system

aka- sensory neuron
Term
B Process/ Opponent Process
Definition
a compensatory mechanism that occurs in response to the primary process elicited by biologically significant events -causes physiological and behavioral changes that are the opposite of those caused by the primary process
Term
Consummatory Behavior
Definition
behavior that serves to bring a natural sequence of behavior to consummation or completion
-usually species-typical modal action patterns
Term
Drug Tolerance
Definition
reduction in the effectiveness of a drug as a result of repeated use of the drug
Term
Efferent Neuron
Definition
a neuron that transmits impulses to muscles
aka- motor neuron
