Investigates the role active, self-produced movement might play in the type of rotation task typically used to assess spatial orientation in children 12 months to 18 months of age. Results indicated that, at least at 12 months, spatial orientation was indeed facilitated by allowing the infants (n = 13) to move through space on their own. (RH)

Discusses three experiments which provide evidence for the conclusions that hypermnesia (increased recall with repeated testing) does not depend on the encoding of material in an imaginal format but is related to the level of recall across conditions within an experiment. (EKN)

Examines sources available for developing a theory of visual literacy and attempts to clarify the meaning of the term. Suggests that visual thinking, a concept supported by recent research on mental imagery, visualization, and dual coding, ought to be the emphasis for future theory development. (FL)

Discusses teachers' use of mental imagery and metaphors in classroom planning. Topics include visualizing, analogies, educational technology as metaphor, malapropisms and mixing theoretical metaphors, designing instruction for the acquisition of abstract concepts, and examples of metaphors of novice and experienced teachers. (LRW)

Investigates how mode of imagery affects imagined interactions and the relationship between affective processing and imagined interaction. Shows that (1) verbal imagery is associated with self-dominance, rehearsal, and understanding whereas visual imagery is associated with more pleasantness; and (2) pleasant imagined interactions are lower in…

Demonstrates visualization techniques using the tuple frequency method that helps organize data generated in computational studies of literary style. Two-dimensional representations of the style of the authors of "The Federalist Papers" are explained that were used to determine the authorship of unattributed papers. (Contains 13…

Finds that people with communication apprehension (CA) who were exposed to visualization reported lower trait and state CA as well as higher attraction levels than those in control or placebo conditions. (SR)

Compares the effects of imagery control and vividness, separately and in combination, on self-report measures of public speaking apprehension (PSA), state communication apprehension (CA), negative thinking, and behavioral disruption. Links imagery control and vividness to reductions in PSA, state CA, negative thinking, and behavioral disruption.…

Examples of imagery and visualization in medicine, sports, and preservice teaching explore the potential of these techniques in mentoring relationships. They help proteges develop a positive self-image in a new role, make mentors' experience more explicit, and depict possible selves toward which proteges can work. (SK)

We have developed an "in vitro assay" for following the interaction between the [alpha][subscript i2] subunit and [beta][subscript 1[gamma]2] dimer from sf9 cells. This method is suitable for education purposes because it is easy, reliable, nonexpensive, can be applied for a big class of 20 students, and avoid the commonly used kinetic approach,…

A study is conducted to prove Kaprekar's conjecture with the help of mathematical concepts such as iteration, fixed points, limit cycles, equivalence cases and basic number theory. The experimental approaches, the different ways in which they reduced the problem to a simpler form and the use of tables and graphs to visualize the problem are…

This article describes how spatial instruction with preservice teachers can be implemented in a middle-grades mathematics methods class. A "Reflect and Discuss" section is included for professional development study. (Contains 4 figures.)

As well as being important for school mathematics, spatial thinking is a big component of advanced mathematical studies too. As Jones (2001:55) points out, "Much of the thinking that is required in higher mathematics is spatial in nature. Einstein's comments on thinking in images are well known. Numerous mathematicians report using spatial…
