The assumption in some current theories of probabilistic categorization is that people gradually attenuate their learning in response to unavoidable error. However, existing evidence for this error discounting is sparse and open to alternative interpretations. We report 2 probabilistic-categorization experiments in which we investigated error discounting by shifting feedback probabilities to new values after different amounts of training. In both experiments, responding gradually became less…

Feedback Discounting in Probabilistic Categorization: Converging Evidence from EEG and Cognitive Modeling
In simple probabilistic learning environments, the informational value of corrective feedback gradually declines over time. This is because prediction errors persist despite learners acquiring the
Combining error-driven models of associative learning with evidence accumulation models of decision-making
This work reports a model-based analysis of changes in the shapes of RT distributions for different category responses at the level of individual stimuli over the course of learning, and develops a new model that combines an associative learning front end with a sequential sampling model of the decision process, showing that the model provides a good account of all aspects of the learning data.
Learning-Induced Changes in Attentional Allocation during Categorization: A Sizable Catalog of Attention Change as Measured by Eye Movements
Five measures relating to the overt allocation of attention across category learning experiments are reported, suggesting that eye-movements are not substantially connected to error in most cases and that aggregate trial-by-trial attention change is generally stable across a number of changing task variables.
Metacognitive monitoring during category learning: how success affects future behaviour
The results indicate that success is generally identified as being the biggest determinant of learning, but do not always recognise cues, such as variability, that enhance learning.
High Cognitive Flexibility Learners Perform Better in Probabilistic Rule Learning
It is demonstrated that cognitive flexibility is associated with the performance after the rule acquisition during the probabilistic rule task, and the accuracy during the post-learning stage was significantly higher than the low flexibility group.
LAG-1: A dynamic, integrative model of learning, attention, and gaze
LAG-1, a dynamic neural field model of learning, attention and gaze that is fit to human learning and eye-movement data from two category learning experiments, produces qualitatively correct fits for learning, behavioural timing and eye movement measures, and also for previously unmodelled empirical phenomena.
Children with autism do not show sequence effects with auditory stimuli.
The data suggest that this finding cannot be attributed readily to participant group differences in discrimination sensitivity, perseveration, difficulties on the associated binary categorization task, or greater reliance on long-term memory.


A model of probabilistic category learning.
A new connectionist model (named RASHNL) accounts for many "irrational" phenomena found in nonmetric multiple-cue probability learning, wherein people learn to utilize a number of discrete-valued
Better learning with more error: probabilistic feedback increases sensitivity to correlated cues in categorization.
2 experiments are reported that demonstrate that using probabilistic feedback in an intentional categorization task leads to sensitivity to correlations among nondiagnostic cues and Computational modeling reveals that exemplar storage coupled with selective attention is necessary to explain this effect.
Recency effects as a window to generalization: separating decisional and perceptual sequential effects in category learning.
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
Rules and exemplars in category learning.
2 experiments are presented that show evidence of both rule induction and exemplar encoding as well as a connectionist model, ATRIUM, that specifies a mechanism for combining rule-and- exemplar-based representation.
ALCOVE: an exemplar-based connectionist model of category learning.
Alcove selectively attends to relevant stimulus dimensions, can account for a form of base-rate neglect, does not suffer catastrophic forgetting, and can exhibit 3-stage learning of high-frequency exceptions to rules, whereas such effects are not easily accounted for by models using other combinations of representation and learning method.
From conditioning to category learning: an adaptive network model.
We used adaptive network theory to extend the Rescorla-Wagner (1972) least mean squares (LMS) model of associative learning to phenomena of human learning and judgment. In three experiments subjects
Cue abstraction and exemplar memory in categorization.
3 generic models of the cognitive processes in a categorization task are compared: cue abstraction model implies abstraction in training of explicit cue-criterion relations that are mentally integrated to form a judgment, lexicographic heuristic uses only the most valid cue, and the exemplar-based model relies on retrieval of exemplars.
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.

The results revealed that participants can integrate new information into their categorization cue set, and some participants demonstrated the ability to discard information previously used when new, more accurate information was introduced.

It is concluded that choice performance is controlled by a mixture of local feedback, in a manner described by the learning model, and more global information encoded in an abstract memory representation, with the balance of the influence shifting toward the latter when local feedback becomes uninformative.
