Abstract:
The differential outcome effect is when learning is enhanced through the application of different outcomes to different conditions of a task. Here we explore whether one difference in learning with differential outcomes is an enhanced categorisation of objects. We demonstrate that participants learning conditional discriminations are better able to identify previously unpaired objects as belonging to the same category when differential outcomes were used in learning these stimuli.

Real-World Application of Classical Conditioning
Higher-order, or second-order, conditioning occurs when a neutral stimulus becomes associated with an already established conditioned stimulus through repeated pairings. For instance, if a dog has been...

Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

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...
