Does imagery impede or facilitate transfer of learning?

Assortative mating can impede or facilitate fixation of underdominant alleles.

Underdominant mutations have fixed between divergent species, yet classical models suggest that rare underdominant alleles are purged quickly except in small or subdivided populations. We predict that underdominant alleles that also influence mate choice, such as those affecting coloration patterns visible to mates and predators alike, can fix more readily. We analyze a mechanistic model of pos...

Does A Learning Organisation Facilitate Knowledge Acquisition And Transfer ?

Knowledge is seen by many as a key source of competitive advantage and innovation in organisations. It follows from this central role of knowledge, that learning is crucial to creating and disseminating knowledge throughout the organisation. The literature describes the learning organisation as an entity that deliberately and continuously acquires, processes and disseminates knowledge in order ...

Visual imagery can impede reasoning

Visual mental images are an important part of human cognition, and it is natural to suppose that they can help us to reason. Various sorts of evidence are compatible with this assumption, including the well-known studies of the mental rotation and the mental scanning of images (Kosslyn, 1980; Shepard & Cooper, 1982). The aim of the present article, however, is to reexamine this assumption, to r...

Visual imagery can impede reasoning.

Although it is natural to suppose that visual mental imagery is important in human deductive reasoning, the evidence is equivocal. This article argues that reasoning studies have not distinguished between ease of visualization and ease of constructing spatial models. Rating studies show that these factors can be separated. Their results yielded four sorts of relations: (1) visuospatial relation...
