Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

High functioning autistic individuals (N=16) were compared with age-matched normal control subjects on a visual recognition matching task. Autistic subjects performed particularly poorly on meaningless material, but were able to utilize meaning to aid their visual memory. Results did not support a simple parallel between autism and mediotemporal…

Compared was the visual memory of 18 deaf and 18 normal hearing children (7- to 12-years-old). Ss' visual discrimination and visual memory were tested with filmstrip materials from Project LIFE (Language Improvement to Facilitate Education). Time scores and error scores were used to measure the performances of both groups. Results showing that…

In a series of six experiments, undergraduate college students visually imagined letters or words and then classified as rapidly as possible the imagined letters for some physical property such as vertical height. This procedure allowed for a preliminary assessment of the temporal parameters of visual imagination. The results delineate a number of…

Two-letter stimulus displays, differing in the magnitude of the horizontal spatial separation between the letters, were presented tachistoscopically to 10 retarded and 1 nonretarded adults. (Author/CL)

The relationship between visual recognition memory and performance on a paired-associate task for good and poor readers was investigated. Subjects were three groups of 21, 21, and 22 children each, with mean IQ's of 98.2, 108.1, and 118.0, respectively. Three experimental tasks, individually administered to each subject, measured visual…

Presented is a test used to measure visual perception ability, which consists of 30 groups of forms that are similar to lines used in forming letters, but do not make letters. They are comparable to nonsense syllables used to simulate words. Each group includes four forms and is numbered. The test was used in Rodenborn's study to determine the…

Five experiments involving a total of 44 college students addressed the effects of intercomponent consistency on skill acquisition in a class of cognitively demanding tasks requiring rapid integration of information and rapid application of rules. The role of consistency of external stimulus-to-rule linkage in facilitating learning and performing…

Humans conduct visual search faster when the same display is presented for a 2nd time, showing implicit learning of repeated displays. This study examines whether learning of a spatial layout transfers to other layouts that are occupied by items of new shapes or colors. The authors show that spatial context learning is sometimes contingent on item…

Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…

Examines the development of young children's analysis of spatial patterns--specifically, hierarchical letter and geometric forms. Suggests that although children as young as four years of age demonstrated substantial analytic competence, their ability to integrate the parts of the spatial array to form a coherent whole was weaker and more easily…

Reviewed are findings from 60 research studies investigating the relationship of visual discrimination, spatial relations, memory, and auditory-visual integration to school learning. (Author/CL)

The patient's body is an image that medical students and residents use to process information. The classic use of images using the patient is qualitative and personal. The contemporary use of images is quantitative and impersonal. The contemporary use of imaging includes radiographic, nuclear, scintigraphic, and nuclear magnetic resonance…

This investigation of cognitive effort begins with a review of cognitive principles relating to memory and graphic encoding of information. The cognitive framework described allows explanation of improved memory due to reparsing of graphic representations. It also provides the basis for optimizing graphical material design to insure best retention…
