The relationship was explored between the ability to understand nonverbal metaphoric similarity and the ability to produce verbal metaphors to talk about that similarity. Subjects, 45 college students, were shown filmed scenes that depicted both metaphoric and literal similarity. Half of the scenes were of stationary objects and half of moving…

The author urges art educators to contribute to holistic education by emphasizing the unique and alternative modes of thinking and acting which are intrinsic to visual arts. He presents two exercises to help students develop a perceptual rather than conceptual or linguistic mode. (Author/SJL)

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)

Eleven tests of reading comprehension, language skills, and cognitive processes were administered to 20 high school readers with learning disabilities and 20 controls. The variance on nonverbal tests was greater for the group with LD than for the controls; some individuals with learning disabilities performed as well as the controls. (Author/DB)

Comparison of cognitive performance of 51 students with hearing loss and 64 hearing students indicated that, at age 10, students with hearing loss performed better on nonverbal tasks and worse on verbal tasks. At age 13, students with hearing loss performed poorly in both verbal and nonverbal tasks. (Author/SW)

Language is shown to be an inappropriate tool for developing a child's mind, based on a Piaget-derived theory of intelligence in which thinking is not primarily language-based. Implications for teachers of normal and deaf students in terms of classroom activities to develop students' thought processes are considered. (KW)

Acetylcholine release in sensory neocortex contributes to higher-order sensory function, in part by activating nicotinic acetylcholine receptors (nAChRs). Molecular studies have revealed a bewildering array of nAChR subtypes and cellular actions; however, there is some consensus emerging about the major nAChR subtypes and their functions in…

The involvement of different subregions of the striatum in place and response learning was examined using a T-maze. Rats were given NMDA lesions of the dorsolateral striatum (DLS), anterior dorsomedial striatum (ADMS), posterior dorsomedial striatum (PDMS), or sham surgery. They were then trained to retrieve food from the west arm of the maze,…

The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

Combined activation of dopamine D1- and NMDA-glutamate receptors in the nucleus accumbens has been strongly implicated in instrumental learning, the process in which an individual learns that a specific action has a wanted outcome. To assess dopaminergic activity, we presented rats with two sessions (30 trials each) of a one-lever appetitive…

Despite their purported neuroanatomic and functional isolation, empirical evidence suggests that sometimes conscious explicit processes can influence implicit motor skill learning. Our goal was to determine if the provision of explicit information affected implicit motor-sequence learning after damage to the basal ganglia. Individuals with stroke…

In two experiments subjects were required to determine whether a random, angular form, presented at any of a number of picture-plane orientations was a "standard" or "reflected" version. Average time required to make this determination increased linearly with the angular departure of the form from a previously learned orientation. (Author/BJG)

In this study, representational thought, which involves the child's ability to function in terms of nonpresent reality, is viewed within a cognitive-developmental framework. To see if disadvantaged children would function in the same way as advantaged children on tasks which required representational thought rather than verbalization, children…
