According to the generalized context model (GCM) (Nosofsky, 1986 ), people represent categories by storing individual exemplars (or examples) in memory, and classify objects based on their similarity to these stored exemplars. For example, the model assumes that people represent the category of ‘birds’ by storing in memory the vast collection of different sparrows, robins, eagles, ostriches (an...

Psychologists of concepts’ traditional assumption that there are many properties common to all concepts has been subject to devastating critiques in psychology and in the philosophy of psychology. However, it is currently unclear what approach to concepts is best suited to replace this traditional assumption. In this article, we compare two competing approaches, the Heterogeneity Hypothesis and...

per patient and year compared to SEK 4 710.9 in 2006 per patient and year. The budesonide/formoterol MART arm was also less costly compared to the FDC arm (SEK 4 163.2 per patient and year) and to the FAC arm (SEK 7 498.5 per patient and year) (Table 2). Similar results were found in Denmark where medication costs for the budesonide/formoterol MART arm (DuoResp® Spiromax®) were less in 2015 DKK...

One important property of human object categories is that they are the categories to which newly observed properties are likely to be generalized. Another is that such categories often exhibit theoretical coherence. This study examined the relationship between inductive generalization and theoretical coherence by manipulating the causal knowledge associated with novel categories and assessing t...

The role of feature correlations in semantic memory is a central issue in conceptual representation. In two versions of the feature verification task, subjects were faster to verify that a feature () is part of a concept (grapefruit) if it is strongly rather than weakly intercorrelated with the other features of that concept. Contrasting interactions between feature correlations and S...

Traditionally, thematic relatedness (chicken and egg) and similarity (chicken and turkey) have been thought of as distinct phenomena, the former the result of associative processes, and the latter reflecting comparison processes . However, recent studies (Bassok & Medin, 1996 ; Wisniewski & Bassok, 1996) suggest that similarity is a result of both association and comparison . This could call fo...

We present a framework for the rational analysis of elemental causal induction—learning about the existence of a relationship between a single cause and effect—based upon causal graphical models. This framework makes precise the distinction between causal structure and causal strength: the difference between asking whether a causal relationship exists and asking how strong that causal relations...

and the rest of the SDSC crew for help getting the hardware and software set up at IETF; Steve Coya and Megan Davies for logistics; and Van Jacobson for work on vat and help in searching for the packet losses. Walt Prue set up a special route for the tunnel from San Diego to DART-net at ISI, and Milo Medin and Jeff Burgan set up a connection from DARTnet to FIX-West for a clear shot to Hawaii a...

This paper illustrates how perception is achieved through interactions among the psychophysical functions of judged features of an object. The theory is that the perceiver places processed features in a multidimensional space of discriminal processes. Each dimension is scaled in units of discrimination performance. The zero coordinate of each feature is its level in an internal standard (norm) ...
