Contexts in learning serve two main functions: eliciting responses like cues or modulating behavior as occasion setters. Understanding when each function dominates is key for future research on learning and memory.
Area of Science:
- Behavioral Neuroscience
- Learning and Memory
- Psychology
Background:
- Theories of learning have historically focused on discrete cues or modulatory roles of contexts.
- Contexts are known to influence learning and behavior during both training and testing phases.
Purpose of the Study:
- To review recent data on the two primary functions of contexts in learning.
- To explore the interrelationship between these contextual functions.
- To identify determinants influencing the dominance of each contextual function.
Main Methods:
- Selective review of existing research on contextual functions in learning.
- Analysis of evidence supporting cue-like and modulatory roles of contexts.
- Discussion of factors influencing contextual function dominance.
Main Results:
- Contexts can act as discrete cues to elicit conditioned responses.
- Contexts can function as occasion setters, modulating responses without eliciting them directly.
- Trial spacing, training amount, and contiguity influence the degree to which contexts serve each function.
Conclusions:
- The cue-like and modulatory functions of contexts are not mutually exclusive.
- Future research should investigate conditions favoring each contextual function.
- Clarifying contextual roles can resolve misconceptions in learning theories.

Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
