Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

This book examines recent theory and research concerning nonverbal experience and behavior and provides examples of the nonverbal experience in contemporary social expression (music, cartoons, fashion, etc.). Chapters include discussions of senses, biorhythms, body image, nonverbal messages from others, environmental factors in nonverbal…

Considered the fact that the scores of high school students taking the entrace tests for college acceptance have steadily declined. Author analyzed the validity of the testing process. (RK)

Behavior of one six year old is altered through the non-verbal cueing of another. (Author)

Study basically supports the Russian theory of the second signal system and its regulatory control of conscious behavior. (Author)

Argues that the child's learning experience should include nondiscursive experiences in addition to verbal learning. (Author/RB)

The role of subject verbalization in the generalization of verbal-nonverbal correspondence was investigated in 12 kindergarten children who underwent either correspondence training (subject verbalization) or performing a behavior verbalized by the experimenter. Pupils who received correspondence training demonstrated greater generalization.…

Ten language impaired and 10 language normal children, aged 3-5), were asked to solve verbal and nonverbal problems requiring color and size judgments. There were no group differences on the verbal tasks, but the language impaired children performed less well on the nonverbal tasks especially on problems dealing with size. (Author/DB)

Investigated whether sustained forms of nonverbal coordinated action facilitates toddlers' generation of verbal discourse with one another. Twenty-four 2-year-olds interacted with an adult, in 2 nonverbal interactive contexts: an imitation game and parallel play. Found that involvement in nonverbal imitation games facilitated toddlers responding…

The profile of spatial ability is of interest across autism spectrum disorders (ASD) because of reported spatial strengths in ASD and due to the recent association of Asperger's syndrome with Nonverbal Learning Disability. Spatial functions were examined in relation to two cognitive theories in autism: the central coherence and executive function…

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,…

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…

The cannabinoid CB1 receptor has been shown to be critically involved in the extinction of fear memory. Systemic injection of a CB1 receptor antagonist prior to extinction training blocked extinction. Conversely, administration of the cannabinoid uptake inhibitor AM404 facilitated extinction in a dose-dependent manner. Here we show that bilateral…
