Multiple external representations (MERs) are central to the practice and learning of science, mathematics and engineering, as the phenomena and entities investigated and controlled in these domains are often not available for perception and action. MERs therefore play a twofold constitutive role in reasoning in these domains. Firstly, MERs stand…

Learners studying mechanical or technical processes via dynamic visualizations often fail to build an accurate mental representation of the system's movements. Based on embodied theories of cognition assuming that action, perception, and cognition are closely intertwined, this paper proposes that the learning effectiveness of dynamic…

This article reviews studies investigating segmentation of dynamic visualizations (i.e., showing dynamic visualizations in pieces with pauses in between) and discusses two not mutually exclusive processes that might underlie the effectiveness of segmentation. First, cognitive activities needed for dealing with the transience of dynamic…

This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension of visualizations. Three theories were evaluated: Ericsson and Kintsch's ("Psychol Rev" 102:211-245, 1995) theory of long-term working memory, Haider and Frensch's ("J Exp Psychol Learn Mem Cognit" 25:172-190, 1999)…

The generation manipulation has been critical in delineating differences between implicit and explicit memory. In contrast to past research, the present experiments indicate that generating from a rhyme cue produces as much perceptual priming as does reading. This is demonstrated for 3 visual priming tasks: perceptual identification, word-fragment…

It is important to incorporate visual thinking into science instruction. Imagination and perception play vital roles in scientific inquiry. Metaphors, like perceptions, are drawn from common experiences and are a means to anchor scientists' thought processes in generating a pattern that bridges the gap between the seen and the unseen. Metaphors…

Using the metaphoric story device of two tribes, one that builds their culture around words and the other which depends primarily on visual perception, this paper suggests a distinctive mental paradigm at work within the society of artists, who pursue visual literacy through graphic ideation. The author discusses his education in art and his…
