Examines the ability of infants to track and anticipate the final orientation of an object. Subjects were infants ranging from an average of four months to eight months old. Three experiments, with the last one as control, were carried out. Concludes that infants show some rudimentary mental rotation from four months of age. (MOK)

A test battery was designed to test the Baddeley and Hitch model of working memory. The battery was administered to 87 children aged 6 and 7 years. Correlations between subtest scores indicated high construct validity for the central executive and phonological loop measures, although not for the visuospatial measures. (Contains 100 references and…

We examined the performance of a group of people with moderately severe Alzheimer's type dementia on a naming task. We found that functional information plays an important role in determining naming performance on both living and non-living things. Perceptual information may play some role in naming living things. We also found some evidence that…

Background: The conclusion from a vast literature on literacy acquisition is that letter knowledge is one of the best predictors of literacy development. The question of the best way to teach children letter sounds has not, as yet, been answered satisfactorily. Aims: The aim of this study was the evaluation of a computer training program using…

Stroop dilution is the reduction of the Stroop effect in the presence of a neutral word. It has been attributed to competition for attention between the color word and neutral word, to competition between all stimuli in the visual field, and to perceptual interference. Five experiments tested these accounts. The critical manipulation was whether…

A study examined the nature of school culture information found in symbolic pictures of schools. One specific goal was to determine the nature of school culture information embedded in verbal interpretations of symbolic school drawings and the accuracy of reviewers' interpretations of the drawings. Another goal was to compare information from the…

It was found that on the color-word test the traditional interference score correlated significantly with the MMPI psychoticism index for females and with the defensive rigidity index for males, but not with the anxiety scores. (SE)

Karl Bruhn, professor of education at Helsinki University for almost 20 years, in addition to writing a history of education, concentrated particularly on carrying out further investigations with his Helsinki Test which was publicly released in 1953. The use of this test is presented in this posthumous article by Bruhn. The Helsinki Test is a…

This discussion of factors involved in the presentation of text, numeric data, and/or visuals using video display devices describes in some detail the following types of presentation: (1) visual displays, with attention to additive color combination; measurements, including luminance, radiance, brightness, and lightness; and standards, with…

This pilot study investigated some relationships between tested ability variables and processing parameters obtained from memory search and visual search tasks. The 25 undergraduates who participated had also participated in a previous investigation by Chiang and Atkinson. A battery of traditional ability tests and several film tests were…

A research study was designed to test the relationship between the number of eye fixations and amount of learning as determined by a criterion referenced posttest. The study sought to answer the following questions: (1) Are differences in eye movement indices related to the posttest score? (2) Do differences in eye movement indices of subjects…

This study was designed to examine relationships between three variables of analysis/integration skill in visual perception and the tendency to retain differentiated memories of sequential visual images in a sample of 206 university undergraduates. Correlation techniques and factor analysis were used to analyze relationships between the perceptual…

The value of H. Myklebust's Picture Story Language Test (PSLT) was examined in a study of differences in written expression between 85 learning disabled (LD) and 125 nonlearning disabled elementary grade children and characteristics of oral expression of the LD students. Using the PSLT, written and oral language samples were obtained from the…

A number of cultural and neurophysiological variables were studied to examine their relationship with sex differences in spatial ability. Five paper-and-pencil spatial ability tests were administered to a group of 50 male and 51 female college students, with approximately equal numbers for each sex being left- or right-handed and left- or…
