Accounts of learning and generalization typically focus on factors related to lasting changes in representation (i.e., long-term memory). The authors present evidence that shorter term effects also play a critical role in determining performance and that these recency effects can be subdivided into perceptual and decisional components. Experimental results based on a probabilistic category structure show that the previous stimulus exerts a contrastive effect on the current percept (perceptual…

Error discounting in probabilistic category learning.

It is concluded that error discounting is an important component of probabilistic learning.

Perceptual variability: Implications for learning and generalization

It is argued that accounting for perception in current generalization protocols will improve the precision of obtained generalization gradients and the ability to infer latent mechanisms and inspire future attempts to use generalizationGradients as a (clinical) predictor or to relate them to individual traits and neural correlates.

Classification response times in probabilistic rule-based category structures: Contrasting exemplar-retrieval and decision-boundary models

The studies add considerable generality to previous ones and suggest that, even in domains involving rule-based category structures, exemplar-retrieval processes play a significant role, and challenged models that posit that RT is a function solely of the distance of a stimulus from rule- based boundaries.

Sequential effects in response time reveal learning mechanisms and event representations.

It is concluded that sequential effects offer a powerful means for uncovering representations and learning mechanisms in animal learning, and research using sequential effects to determine mental representations is discussed.

Context-Gated Statistical Learning and Its Role in Visual-Saccadic Decisions

This work examined the mechanisms of adaptation in a nonstationary environment in the context of visual-saccadic inhibition of return (IOR), finding that adaptation occurred in the absence of contextual signals but was more pronounced in the presence of contextual cues.

The Sequence of Study Changes What Information Is Attended to, Encoded, and Remembered During Category Learning

These results provide support for the sequential attention theory proposing that inductive category learning takes place through a process of sequential comparisons between the current and previous items.

Limits in decision making arise from limits in memory retrieval

The best way to convey information to people is to present it in a distorted, idealized form, and these results suggest firm limits on human rationality and have broad implications for how to train humans tasked with important classification decisions.

Recency effects have been well established in memory and probability learning paradigms but have received little attention in category earning research, and a functional interpretation of REs predicts that people are able to learn sequential dependencies and incorporate this information into their responses.

Sequence effects in the categorization of tones varying in frequency.

A memory and contrast model, according to which only ordinal information about the differences between the current stimulus and recent preceding stimuli is used, best accounted for these data.

Sequence effects in categorization of simple perceptual stimuli.

It is argued that this category contrast effect cannot be accounted for by extant exemplar or decision-bound models of categorization and suggests the use of relative magnitude information in categorization.
