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 learned to categorize hypothetical patients with particular symptom patterns as having certain diseases. When one disease is far more likely than another, the model predicts that subjects will substantially overestimate the diagnosticity of the more valid symptom for the rare disease. The results of…

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
Perceptual Categorization: Connectionist Modelling and Decision Rules
Only the exponential ratio rule and the winner-take-all architecture, acting on the networks’ output activations that corresponded to responses available on test, were capable of fully predicting the mean response results.
Cue Competition in Human Categorization : Contingency or the Rescorla-Wagner Learning Rule ? Comment on Shanks ( 1991 )
Shanks (1991) reported experiments that show selective-learning effects in a categorization task, and presented simulations of his data using a connectionist network model implementing the
Cue Competition Effects: Theoretical Implications for Adaptive Network Learning Models
It is proved that cue competition effects obtained with statistically independent cues cannot be explained by many previous adaptive network learning models, including those based on the delta learning rule.
Stimulus Generalization and Representation in Adaptive Network Models of Category Learning
An exponential-decay relationship between the probability of generalization and psychological distance has received considerable support from studies of stimulus generalization (Shepard, 1958) and
Combining exemplar-based category representations and connectionist learning rules.
Only the exemplar-based network accounted for all the major qualitative phenomena; it also achieved good quantitative predictions of the learning and transfer data in both experiments.
Toward a unified model of attention in associative learning
The discussion summarizes how the approach accounts for a variety of other ‘‘irrational’’ phenomena in associative learning, including base rate effects, perseveration of attention through relevance shifts, overshadowing, and the extrapolation of rules near exceptions.
An adaptive approach to human decision making: Learning theory, decision theory, and human performance.
This article describes a general model of decision rule learning, the rule competition model, composed of 2 parts: an adaptive network model that describes how individuals learn to predict the
Learning in a changing environment.
3 experiments investigating learning in changing environments show that participants were responsive to both abrupt and gradual changes in cue-outcome relations, and in contrast to earlier claims that these tasks are learned implicitly, participants showed good insight into what they learned.
Modeling Probabilistic Categorization Data: Exemplar Memory and Connectionist Nets
In probabilistic categorization tasks, the correct category is determined only probabilistically by the stimulus pattern Data from such experiments have been successfully accounted for by a simple


Toward a modern theory of adaptive networks: expectation and prediction.
The adaptive element presented learns to increase its response rate in anticipation of increased stimulation, producing a conditioned response before the occurrence of the unconditioned stimulus, and is in strong agreement with the behavioral data regarding the effects of stimulus context.

Correlated symptoms and simulated medical classification.
Across four experiments, subjects proved to be sensitive to configural information and tended to choose the case that preserved the correlation over the cases that broke the correlation, even when the case with correlated symptoms contained fewer typical symptoms.
Context theory of classification learning.
A context theory of classificatio n is described in which judgments are assumed to derive exclusively from stored exemplar information, and the main idea is that a probe item acts as a retrieval cue to access information associated with stimuli similar to the probe.
Limitations of exemplar-based generalization and the abstraction of categorical information.
An evaluation of exemplar-based models of generalization was provided for illdefined categories in a category abstraction paradigm. Subjects initially classified 35 high-level distortions into three

A framework for classification learning is presented that assumes that learners use presented instances to infer the density functions of category exemplars over a feature space and that subsequent classification decisions employ a relative likelihood decision rule based on these inferred density functions.
On the psychology of prediction
In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. Two classes of
Forgetting in an association memory
Some modern experiments, involving the implantation and stimulation of microelectrodes in the brain, have suggested that experiences far removed in time can be evoked in great informational detail by appropriate stimulation of barin tissue.
Concepts and concept formation.
The idea that cohesive categories maximize the probability of particular properties given the category fares no better, and Sternberg suggests that the apparent naturalness of a concept increases with the familiarity of the concept, and decreases with the number of transformations specified in the concept.
