In S. Kanazawa's (see record 2004-12248-010) evolutionary theory of general intelligence (g), g is presented as a species-typical information-processing mechanism. This conceptualization of g departs radically from the accepted conceptualization of g as a source of individual differences that is manifest in the positive manifold. Kanazawa's theory…

Modularity has been the subject of intense debate in the cognitive sciences for more than 2 decades. In some cases, misunderstandings have impeded conceptual progress. Here the authors identify arguments about modularity that either have been abandoned or were never held by proponents of modular views of the mind. The authors review arguments that…

The author concentrates on two components of memory which contribute to the reproduction and recognition of melodies, namely, melodic contour and musical scale. A new experiment is reported that shows the interdependence of both components. (Author/RK)

It is proposed that many phenomena of human hypothesis testing can be understood in terms of a general positive test strategy. With this strategy, there is a tendency to test cases that are expected to have the property of interest rather than those expected to lack that property. (Author/LMO)

A view of cognitive development emphasizing the formal properties of cognitive structures and processes that remain invariant throughout development is described. Cognitive development is guided by complex sets of constraints, specific sets are tailored for particular cognitive domains, and constraints limit the class of naturally learnable…

The author analyzes some recent developments in the debate over the status of mental imagery. He attempts to specify what a propositional theory is, and considers arguments for and against the imagery position, i.e., whether visual imagery is encoded in terms of properties that are quite spatial and modality specific. (Author/RK)

A theory for the visual and cognitive processing, which accounts for slower naming of pictures than reading of words, is introduced. Two experiments assessed the differences distinguishing word reading and picture naming, using 58 undergraduates. The coding of the mind is neither intrinsically linguistic nor imagistic; it is abstract. (TJH)
