A unique behavioral paradigm has been developed for "Periplaneta americana" that assesses the timing and success of memory consolidation leading to long-term memory of visual-olfactory associations. The brains of trained and control animals, removed at the critical consolidation period, were screened by two-directional suppression subtractive…

There is strong converging evidence suggesting that developmental dyslexia stems from a phonological processing deficit. However, this hypothesis has been challenged by the widely admitted heterogeneity of the dyslexic population, and by several reports of dyslexic individuals with no apparent phonological deficit. In this paper, we discuss the…

Sixty-two adults with mental retardation of heterogeneous etiology performed four facial emotion discrimination tasks and two facial nonemotion tasks. Staff members familiar with the participants completed measures of social adjustment (the Socialization and Communication domains of the Vineland Adaptive Behavior Scales and the Social Performance…

Previous research has shown that synchronized flicker can facilitate detection of a single Kanizsa square. The present study investigated the role of temporally structured priming in discrimination tasks involving perceptual relations between multiple Kanizsa-type figures. Results indicate that visual information presented as temporally structured…

Purpose: Investigations of the cognitive processes underlying specific language impairment (SLI) have implicated deficits in verbal short-term and working memory and in particular the storage and processing of phonological information. This study investigated short-term and working memory for visuospatial material for a group of children with SLI,…

Adults with Asperger Syndrome (AS) can recognise simple emotions and pass basic theory of mind tasks, but have difficulties recognising more complex emotions and mental states. This study describes a new battery of tasks, testing recognition of 20 complex emotions and mental states from faces and voices. The battery was given to males and females…

Language delay and impairment are salient features of autism. More specifically, there is evidence of atypical semantic organization in autism, but the functional brain correlates are not well understood. The current study used functional MRI to examine activation associated with semantic category decision. Ten high-functioning men with autism…

In this article, the authors describe Picture Power, a project they implemented during late spring in a full-day Montessori preschool-kindergarten program in Philadelphia. In this project, the authors set out to gather information about children's visual learning. The underlying question was whether artwork could provide useful clues to inform…

This study investigated the influence of the visual display of an instructional design (ID) model on preservice teachers' perceptions of the ID process. Forty-six undergraduate education majors (29 females and 17 males) enrolled in an introductory education class during the spring of 1995 at an institution in the United States' Rocky Mountain west…

Graphomotor output was assessed in children with attentional problems using the Repeated Patterns Test (RPT). Forty-eight subjects, ages 8 to 13, who met standard criteria for Attention Deficit Hyperactivity Disorder (ADHD), participated, of whom 24 had primarily Inattentive Type and 24 had Combined Type ADHD. Both groups had intact visuomotor…

"Exploring" is a magazine of science, art, and human perception that communicates ideas museum exhibits cannot demonstrate easily by using experiments and activities for the classroom. This issue concentrates on size, examining it from a variety of viewpoints. The focus allows students to investigate and discuss interconnections among…

Does a drawing embody the form and focus of what the artist actually sees, or instead, is it only after seeing the finished drawing that the artist knows the true meaning of his or her visual experience? It is the knowledge of the visual experience that drives the representation of it. Knowledge of the visual experience is present in varying…

The purpose of the study reported in this paper was to examine the effect of visuals possessing different amounts of realistic detail and the effects of integrating covert and overt rehearsal strategies into visually complemented prose instruction. A total of 128 university students participated in the study, which involved a prose text on the…

A few of the relationships between visual and verbal components are explored. Visuals are considered to be things that can be seen, visible things other than printed words that are used in a communication process. The term verbal applies to written or spoken words. The natural tendency for visual and verbal components to be mutually supportive has…

This study reviewed possibilities for looking at aesthetic perception in art using the D. E. Berlyne approach, identifying alternative methods, and reporting the results of a factor analytic study of preferences of young college adults for abstract art. The Berlyne approach used stimulus objects of simple to complex abstract components of the more…
