Human categorization research is dominated by work in classification learning. The field may be in danger of equating the classification learning paradigm with the more general phenomenon of category learning. This paper compares classification and inference learning and finds that different patterns of behavior emerge depending on which learning mode is engaged. Inference learning tends to foc...

An event contingent diary method compared the rated salience of ambient external and internal cues reported in association with instances of feeling hungry and ill, to test whether environmental and psychological factors might be differentially identified in conjunction with these states. In cases of hunger but not illness, external and internal events were equally salient cues. However, within...

Research on the internal structure of categories has shown that central tendency, frequency of instantiation, and ideals are determinants of graded structure (Barsalou, 1985). Vast differences in the relative roles of these factors have been observed depending on the type of category, the immediate context of evaluation, and the domain knowledge or experiential history of the individual. In two...

Category-specific semantic deficits refer to the inability to name objects from a particular category while the naming of words outside that category remains relatively unimpaired. We suggest that such semantic deficits arise from the random lesioning of a unified semantic network in which internal category representations reflect the variability of the categories themselves. This is demonstrat...

We give here some examples of non pointed protomodular categories C satisfying a property similar to the property of representation of actions which holds for the pointed protomodular category Gp of groups: any slice category of Gp, any category of groupoids with a fixed set of objects, any essentially affine category. This property gives rise to an internal construction of the center of any ob...

identifying the influential factors in sustainable competitive advantage through a resource based view (rbv) is one of the main and most important ways of creating a sustainable competitive position. the purpose of this paper, therefore, is to identify the csf in gaining sustainable competitive advantage in bank mellat based on a resource based view. in order to do this, a conceptual model was ...

We investigate /xpoint operators for domain equations. It is routine to verify that if every endofunctor on a category has an initial algebra, then one can construct a /xpoint operator from the category of endofunctors to the category. That construction does not lift routinely to enriched categories, using the usual enriched notion of initiality of an endofunctor. We show that by embedding the ...

in this article, we have shown, for the add-point monad t, thepartial morphism category set*is isomorphic to the kleisli category sett. alsowe have proved that the category, sett, of t-algebras is isomorphic to thecategory set of pointed sets. finally we have established commutative squaresinvolving these categories.

The internal size of an objectM inside a given category is, roughly, the least infinite cardinal λ such that any morphism from M into the colimit of a λ+-directed system factors through one of the components of the system. The existence spectrum of a category is the class of cardinals λ such that the category has an object of internal size λ. We study the existence spectrum in μ-abstract elemen...
