Attention, similarity, and the identification-categorization relationship.

  • 1986
TLDR
A unified quantitative approach to modeling subjects' identification and categorization of multidimensional perceptual stimuli is proposed and tested and some support was gained for the hypothesis that subjects distribute attention among component dimensions so as to optimize categorization performance.

  • 1984
TLDR
It is suggested that the same basic choice processes may operate in the two paradigms but that the similarity parameters that determine performance change systematically according to the structure of the choice paradigm. Expand
Attention, similarity, and the identification-categorization relationship.
A unified quantitative approach to modeling subjects' identification and categorization of multidimensional perceptual stimuli is proposed and tested. Two subjects identified and categorized the sameExpand
Rule-plus-exception model of classification learning.
TLDR
The authors propose a rule-plus-exception model (RULEX) of classification learning, which accounts for numerous fundamental classification phenomena, including prototype and specific exemplar effects, sensitivity to correlational information, difficulty of learning linearly separables versus nonlinearly separable categories, selective attention effects, and difficulty oflearning concepts with rules of differing complexity.

An exemplar-based random walk model of speeded classification.
TLDR
An exemplar-based random walk model for predicting response times in tasks of speeded, multidimensional perceptual classification and builds bridges between the domains of categorization and automaticity is proposed and tested. Expand
Attention and learning processes in the identification and categorization of integral stimuli.

  • 1987
TLDR
Evidence was provided that similarity among exemplars decreased as a function of identification learning, and various alternative classification models, including prototype, multiple-prototype, average distance, and "value-on-dimensions" models, were unable to account for the results. Expand
A response-time approach to comparing generalized rational and take-the-best models of decision making.
TLDR
The authors develop and test generalized versions of take-the-best (TTB) and rational (RAT) models of multiattribute paired-comparison inference and suggest that the vast majority of subjects adopted the generalized TTB strategy. Expand
Exemplar-Based Accounts of Relations Between Classification, Recognition, and Typicality
Previously published sets of classification and old-new recognition memory data are reanalyzed within the framework of an exemplar-based generalization model. The key assumption in the model is that,Expand
Dissociations Between Categorization and Recognition in Amnesic and Normal Individuals: An Exemplar-Based Interpretation
In recent work, the finding of dissociations between categorization and recognition in amnesic and normal individuals has been taken as evidence of multiple memory systems mediating these tasks. TheExpand

  • 1 February 1991
TLDR
Evidence was provided that Ss allocated attention to the psychological dimensions differentially for classification and recognition, and the distribution of attention came close to the ideal-observer distribution for classification, and some tendencies in that direction were observed for recognition.
