Learning Exam 1 Definitions
Term | Definition |
---|---|
Control Systems Theory | A branch of science that analyzes goal-directed behaviors in both living creatures and inanimate objects. |
Comparator | In CST, a device that compares its goal state (reference input) with the current situation (actual input) and signals that action is necessary if the two are not equal. |
Learning | A more or less permanent change in behavior resulting from personal experiences in the environment. |
Ethologist | A scientist that studies how animals behave in their natural environment. |
Associationists | Philosophers who developed early theories about how people learn to associate separate thoughts or ideas as a result of their experiences. |
Nativism | The hypothesis that some ideas are innate (inborn) and do not depend on an individual's past experience. |
Independent Variable | In scientific research, a variable that the experimenter manipulates to determine how this affects the dependent variable. |
Dependent Variable | In psychological research, the behavior of a subject that is measured by the experimenter to see how it is affected by changes in the independent variable. |
Intervening Variable | A theoretical concept that cannot be observed directly, but is used in science to predict the relationship between the independent and dependent variables. |
Contiguity | One of Aristotle's principles of association, which states that two ideas will be associated if they tend to occur together in space or time. |
Similarity | One of Aristotle's principles of association, which states that the thought of one concept often leads to the thought of similar concepts. |
Contrast | One of Aristotle's principles of association, which states that the thought of one concept often leads to the thought of the opposite concept. |
Long-Term Potentiation | An increase in the strengths of the connections between neurons caused by electrical stimulation, which can last for weeks or months. |
Arborization | The branching of dendrites of neurons, a process that occurs especially rapidly before birth and during the first year of an child's life. |
Neurogenesis | The growth of new neurons. |
Reflex | An innate movement that can be reliably elicited by presenting the appropriate stimulus. |
Tropism | An innate movement of a creature's entire body in response to specific stimulus. The 2 major categories are kineses and taxes. |
Kinesis | A tropism in which the direction of the movement is random in relation to the stimulus. |
Taxis | A tropism in which the eliciting stimulus determines the direction of the creature's movement. |
Fixed Action Pattern | An innate sequence of behaviors that is elicited by a specific stimulus and, once started, continues to its end whether or not the behaviors are appropriate in the current situation. |
Unconditioned Stimulus | In classical conditioning, a stimulus that naturally elicits a specific response (an unconditioned response) |
Unconditioned Response | In classical conditioning, an innate response that is elicited by the unconditioned stimulus. |
Conditioned Stimulus | An initially neutral stimulus that develops the capacity to elicit a conditioned response after it is paired with an unconditioned stimulus |
Conditioned Response | The response that is elicited by a conditioned stimulus after classical conditioning has taken place |
Acquisition Phase | The period in the learning process when an individual is learning a new behavior. |
Extinction | In classical conditioning, presenting the conditioned stimulus without the unconditioned stimulus; responding decreases and eventually disappears. |
Spontaneous Recovery | In classical or operant conditioning, the reappearance of a response that has undergone extinction after a passage of time without further conditioning trials. |
Generalization | The transfer of a learned response from one stimulus to another, similar stimulus. |
