It is hypothesized in this study that children reared with "concerned" mothers (N) will display significantly superior intellectual performance and less neurological impairment as compared with children reared with neglectful mothers (MN) and children diagnosed as failure to thrive (FTT, falling below the third percentile in height and weight). The FTT children will show significantly more deficits than both N and MN groups. The participants in this study were forty-five children rigidly matched on all possible variables. F-tests and Newman-Keuls' analyses reveal severe intellectual deficits in both MN and FTT groups. The FTT group displayed significantly more neurological deficits lending support for a nutritional basis of this syndrome as opposed to the traditional psychogenic explanation.

Advanced Placement and dual credit programs are designed for high school students and are used to earn college credit and possibly gain college admissions advantages. The present research examined the impact of participation in one or both programs on four-year college graduation rates. Findings indicated significant differences between the programs as well as with students who did not participate in either program. Students in AP achieved the highest four-year graduation rate, followed by students in dual credit, both programs, and neither program. These findings indicate the need for further study to determine whether the programs substantially contribute to four-year graduation rates and what the implications are.

The problem under investigation was the predictive value of a preschool screen. The subjects were 111 kindergartners. First, the need for a preschool screen was established. Second, the literature concerning other preschool devices was reviewed. Third, a specific screen was assessed in terms of validity. Fourth, a consideration of the predictive value of this screen in relation to scholastic achievement as indicated by the Metropolitan Readiness Test was made. A multiple regression analysis was performed, and the cross-validation of a number of prediction equations and cutoff scores was significant. Although statistical significance was achieved, high-risk youngsters could not be accurately identified. This research indicated that the instrument evaluated shows promise if refined by additional research.

Investigations of children's spatial ability have typically looked at performance on laboratory tasks, and none have examined differences between learning disabled and non-learning disabled children. The present study surveyed sixty-seven parents of third and sixth grade children about the types of spatial activities children engage in everyday. Parents of learning disabled and non-learning disabled children were included. Results provided information about the types of spatial activities children engage in and the relationships between participation and performance. Major findings included differences between learning disabled and non-learning disabled children in navigational ability and in the strategies employed in difficult or ambiguous spatial situations. Findings were discussed in terms of the influence learning disabled children's negative self evaluations have on their performance.
