Similar and different: The differentiation of basic-level categories
- Retrieval of exemplar and feature information in category learning. Hurwitz, Joshua B. // Journal of Experimental Psychology. Learning, Memory & Cognition;Jul94, Vol. 20 Issue 4, p887
Discusses experiments which manipulate the opportunity of using whole exemplars when categorizing test patterns by providing either whole or fragmented patterns. Assumptions on what information subjects use during category learning with independent features; Exemplar model; Feature-node network...
- Predicting features for members of natural categories when categorization is uncertain. Malt, Barbara C.; Ross, Brian H. // Journal of Experimental Psychology. Learning, Memory & Cognition;May95, Vol. 21 Issue 3, p646
Suggests that in feature prediction people consider all the categories an object could belong to when they judge the likelihood that the object has a feature. Consideration of the most likely category; Evidence on alternative categories with feature probabilities for familiar objects in...
- Associative and similarity-based processes in categorization decisions. Hampton, James A. // Memory & Cognition;Sep97, Vol. 25 Issue 5, p625
Focuses on a study which examined the associative and similarity-based processes of systematic differences in categorization time and different items in natural categories. How experiments were conducted; Materials used in experiments; Findings of the study.
- Event category learning. Kersten, Alan W.; Billman, Dorrit // Journal of Experimental Psychology. Learning, Memory & Cognition;May97, Vol. 23 Issue 3, p638
Examines the learning of event categories, in particular, categories of simple animated events, each involving a causal interaction between two characters. Selection of event attributes to reflect distinctions made by the verbs; Generation of internal feedback to adjust the salience of...
- Straight talk about linear separability. Smith, J. David; Murray Jr., Morgan J.; Minda, John Paul // Journal of Experimental Psychology. Learning, Memory & Cognition;May97, Vol. 23 Issue 3, p659
Studies linear separability in human categorization. Evaluation of the linear separability constraint; Exemplar-based models of categorization; Multiplicative calculations of similarity; Convergence of perspectives on categorization; Influence of prototypes and additive evidence rules on...
- Similarity-versus rule-based categorization. Smith, Edward E.; Sloman, Steven A. // Memory & Cognition;Jul94, Vol. 22 Issue 4, p377
Presents a study which supports the hypothesis that categorization can be done in two ways, by similarity and by rule. Evidence that categorization cannot be reduced to similarity in Rips study (1989); Dissociation between categorization and similarity; Occurrence of an exclusive reliance on...
- Essentialism and graded membership in animal and artifact categories. Kalish, Charles W. // Memory & Cognition;May95, Vol. 23 Issue 3, p335
Discusses studies on the use of graded membership in treating membership in animal and artifact categories. Difference between typicality and category membership; Essentialist structure of animal categories; Limitations of the study.
- Categorical denials. // U.S. Catholic;Jan98, Vol. 63 Issue 1, p6
Focuses on moral theologian Stanley Hauerwas' remarks on society's tendency to put people in categories.
- Comparison-based learning: Effects of comparing instances during category learning. Spalding, Thomas L.; Ross, Brian H. // Journal of Experimental Psychology. Learning, Memory & Cognition;Nov94, Vol. 20 Issue 6, p1251
Examines the comparison of new instances with similar old instances during category learning. Observation of features common to the compared instances; Importance of common features over equally frequent features that are not so common to compared instances; Goals of the experiments conducted;...
