Do attitudes towards persons with handicaps really shift over time? Comparison between 1975 and 1988.

A replication of a study by Spreen (1977) was conducted to assess whether a positive shift in attitudes towards persons with mental retardation has occurred. Undergraduate students (N = 191) were tested. Results compared to those of Spreen (1977) showed a positive shift over the 13-year period. We also tested the hypothesis that exposure to a course on developmental disabilities and contact with individuals with mental retardation would improve students' attitudes. Findings support this hypothesis, although results suggest the influence of a third variable, namely, public awareness.

The relationship between learning disability, emotional disorders, and neuropsychology; some results and observations.

Emotional disorders may precede learning disabilities, follow learning disabilities, or occur at the same time. This paper discusses evidence supporting each of these hypotheses, focussing on the possibility that both learning disabilities and emotional disorders, or at least some subforms of them, may have a common origin in neurological dysfunction. A model of interaction of the many factors involved in both the development and the persistence across age for both learning disabilities and emotional disorders is presented and avenues of research are discussed. Data from a 15-year follow-up study which illustrate some of these complex relationships are presented.

Fifteen-year stability of some neuropsychological tests in learning disabled subjects with and without neurological impairment.

The stability of the WISC/WAIS-R and seven other commonly used neuropsychological tests over a period of 15 years was investigated in 133 learning-disabled subjects, and for subgroups with hard neurological signs, soft neurological signs, and without neurological findings. Results showed high and significant correlation coefficients between time 1 (mean age 10 years) and time 2 (mean age 25 years), even though for some tests a change from the children's to the adult version occurred. Using a repeated-measures multivariate design, the three subgroups did not differ on this limited test battery. The correlation coefficients for the three subgroups provide an estimate of the range of stability in three different samples.

Psychometric properties of dichotic words tests.

The current study examined the reliability of a measure of ear advantage and the total scores derived from the dichotic listening task. The scores for both measures were found: (1) not to differ from the normal distribution, and (2) to be reliable over items, tests, and time. However, the total scores were dependent upon stimulus materials and experience. In addition, a psychometric classification model was proposed and it was found that the majority, at least 51.6% of the subjects, did not exhibit a truly measureable ear advantage. Finally, it was argued that total scores as well as ear advantage should be considered in the analysis of dichotic listening studies.
