This paper, part of an evaluation of the early intervention project at the Frank Porter Graham Child Development Center, deals primarily with results of the Bayley Mental Development Index (MDI). The MDI was administered to experimental and control infants from lower socioeconomic background at 6, 12 and 18 months of age. Results (discussed in…

Recent comprehensive analyses such as those by Harnishfeger and Wiley (1975) and Zajonc (1976) indicate the existence of a national and international downward trend in achievement and intelligence test scores. An analysis of the achievement and intelligence test scores in a small, upper middle class, New Jersey elementary school district showed an…

This article provides a tutorial introduction to Artificial Intelligence (AI) research for those involved in Computer Assisted Instruction (CAI). The general theme is that much of the current work in AI, particularly in the areas of natural language understanding systems, rule induction, programming languages, and socratic systems, has important…

The Fall, 1974 South Carolina Statewide Testing Program was administered to nearly all of South Carolina's fourth and seventh grade students and a sample of ninth and eleventh grade students participated in the testing program. There were 49,068 fourth graders, about 98 percent, and 53,662 seventh graders, about 99 percent, tested. A…

TORTIS (Toddler's Own Recursive Turtle Interpreter System) is a device which can be used to study or nurture the cognitive development of preschool children. The device consists of a "turtle" which the child can control by use of buttons on a control panel. The "turtle" can be made to move in prescribed directions, to take a…

The history of attempts by psychologists to determine the contribution of personality to intelligence has not been one of unqualified success. Part of the problem may be in the balance of granularity of analyses on the intelligence side and the personality side. A comprehensive analysis of the contributions of extraversion and neuroticism to…

Retardates, primary students, and college students were given either a reversal or an intradimensional shift after either a criterion of five or twenty correct on a pre-transfer problem. An automated two-choice apparatus projected planometric color and form cues from the rear onto panels that the subject was instructed to press. Both the…

This study attempted to discover the relative contribution to spelling achievement (the dependent variable) of each of the following independent variables: intelligence, visual memory, auditory memory, structural analysis, phonetic analysis, reading comprehension, and vocabulary. Participating in the study were 190 students from six seventh-grade…

This paper attempts to clarify some of the issues raised in the author's earlier paper, "A Theoretical Perspective on the Relationship between Bilingualism and Thought" (Working Papers on Bilingualism, No. 1), as a response to Gerald Neufeld's critique, which appeared in No. 2 of the same series. The present paper argues that Neufeld mistakenly…

The course in parsing English is essentially a survey and comparison of several of the principal systems used for understanding natural language. The basic procedure of parsing is described. The discussion of the principal systems is based on the idea that "meaning is procedures," that is, that the procedures of application give a parsed…

This paper examined the performance of kindergarten and first grade children in an inner-city school during the first full year of the Primary Education Project (PEP) Quantification (early mathematics) curriculum. The curriculum was based on a hierarchically sequenced set of objectives and accompanying criterion-referenced placement and diagnostic…

The effectiveness of test adaptation based on item selection and reordering of a Spanish (Mexican) version of the Peabody Picture Vocabulary Test (PPVT) was examined. Translated forms were administered to a sample of Mexican students. One item from each pair (A and B) was selected and reordered using a priori rules. The revised instrument was…

In this paper it is shown that one's conception of intelligence and its development profoundly affects the formulation of educational objectives. A mechanistic conception of intelligence leads to the definition of objectives as a collection of fragmented "cognitive skills" that have little to do with children's development of intelligence. A…

The relationship between geographic mobility and pupil achievement in reading was investigated for a sample of 2,072 sixth-grade children. A three-way analysis of variance design provided for the study of three levels of mobility when boys and girls were grouped into three levels of ability. Two additional covariates were employed to cause the…

Drawn from a 1967 conference on gerontology, these 11 papers consider the nature of age changes (for better or worse) in high grade intellectual work and decision making of the kind found in industrial management and comparable walks of life. The first paper draws implications for higher intellectual activities from existing knowledge of age…
