We conducted an experiment in which children and adults were asked to learn a set of categories for which a single-feature rule (the criterial attribute) or overall family resemblance would allow for perfect performance. Test stimuli were presented after the category was learned and were designed such that the information provided by the rule conflicted with the information provided by the fami...

In contemporary aspectological researches, especially in those within the domain of category aspect verb lexemes formalized as a binary category, there are more and researches oriented to empirical verification claims about its non nature. This paper also has such orientation, precisely on example držati, reflexive form držati se, grammatical derivatives (e.g. udržati, sadrža(va)ti, podržati, p...

The definition of a category of (T,V)-algebras, where V is a unital commutative quantale and T is a Set-monad, requires the existence of a certain lax extension of T. In this article, we present a general construction of such an extension. This leads to the formation of two categories of (T,V)-algebras: the category Alg(T,V) of canonical (T,V)-algebras, and the category Alg(T′,V) of op-canonica...

Joyal and Street note in their paper on braided monoidal categories [9] that the 2–category V –Cat of categories enriched over a braided monoidal category V is not itself braided in any way that is based upon the braiding of V . The exception that they mention is the case in which V is symmetric, which leads to V –Cat being symmetric as well. The symmetry in V –Cat is based upon the symmetry of...

The ability to generate items belonging to categories in verbal fluency tasks has been attributed to frontal cortex. Nonverbal fluency (e.g., design fluency) has been assessed separately and found to rely on the right hemisphere or right frontal cortex. The current study assessed both verbal and nonverbal fluency in a single group of patients with focal, frontal lobe lesions and age- and educat...

Joyal and Street note in their paper on braided monoidal categories [10] that the 2–category V–Cat of categories enriched over a braided monoidal category V is not itself braided in any way that is based upon the braiding of V. What is meant by “based upon” here will be made more clear in the present paper. The exception that they mention is the case in which V is symmetric, which leads to V–Ca...

The influential competition between verbal and implicit systems (COVIS) model proposes that category learning is driven by two competing neural systems-an explicit, verbal, system, and a procedural-based, implicit, system. In the current fMRI study, participants learned either a conjunctive, rule-based (RB), category structure that is believed to engage the explicit system, or an information-in...

Perceptions of personal risk (i.e. risk likelihood) occupy a central role in theories of individual health behavior. There is no agreement, however, concerning the best approach for measuring these perceptions. We compared a percentage scale with a seven-point, verbally labeled scale. Data from college student subjects (N = 215) showed that the correlations between risk factors and risk likelih...
