This paper reports on a 14-year follow-up study of two developmentally retarded Japanese children, a brother and sister, who had been kept shut up in a small shack before being rescued (at ages 5 and 6 respectively). Following birth they consistently suffered malnutrition, maternal deprivation, social isolation from adults, language deprivation,…

A study investigated the effects of nonverbal and verbal classification abilities on reading comprehension. Subjects, 104 fourth grade students, were tested on three measures of classification skill (a shifting of criteria task, a free sorting task, and a three-level hierarchical classification task) and on a measure of recall of relevant story…

This document (which has the form of a magazine) provides a variety of articles, stories, editorials, letters, interviews, and other types of magazine features (such as book reviews) which focus on human genetics. In addition to providing information about the principles of genetics, nearly all of the sections in the "magazine" address moral,…

The study investigated cultural bias in the verbal items of the Wechsler Intelligence Scale for Children-Revised (WISC-R). Six verbal subtests of the WISC-R were administered to 40 Anglo, 40 Mexican-American, and 40 Navajo intermediate grade students matched for grade level, sex, and socioeconomic status. The responses of three groups of subjects…

Advocates for minority students charge that special education placement of racially or culturally different students is unfair because the tests, standardized on white, middle-class children, do not accurately reflect the learning rate or potential achievement level of others. For this reason, reliance on IQ tests for placement of minority…

This paper discusses ways in which artificial intelligence (AI) technologies may be used to aid students for whom English is a second language in the development of language and reading skills, and asserts that the coupling of technology with close adult-teacher contacts within a context of cultural precedents and social rewards is an important…

A public school district in Alabama uses the Otis Lennon School Ability Test (OLSAT) in place of the Wechsler Intelligence Scale for Children (Revised) (WISC-R) as a screening device for students who are referred for possible special education placement. To determine the relationship between the two tests, Pearson product moment correlation…

This paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…

The study examined the perceptions of two gifted samples (n=54) and a nongifted control group (n=130) of preadolescent boys (ages 12-13) regarding their school and peer experiences, intrafamily roles, discipline and identification models, and career choices. Results of a 62-item questionnaire indicated that the group identified as having…

The concept of creativity has many attributes and is a significant factor in our lives. Creative persons are observant, express part-truths, see things as others do not, are independent in cognitive faculties, are motivated by their talent and values, can hold many ideas at once, have greater sex drive, see a complex world, and have strong egos.…

For the past two decades, increasing numbers of scientists have been optimistic about finding other intelligent life forms in our galaxy. On the other hand, as knowledge has grown regarding how life developed on earth, a scientific counterrevolution has evolved. Simply stated, it questions the inevitability of widespread life within our galaxy,…

Different aspects of human-machine interaction are discussed in the five brief papers that comprise this report. The first paper, "Some Observations on Mental Models," discusses the role of a person's mental model in the interaction with systems. The second paper, "A Psychologist Views Human Processing: Human Errors and Other…

A group of 24 14-year-old students were presented with sets of algebra tasks using the Leeds Modelling System (LMS), a computer-based modeling system. Four months later, these same students were given a paper-and-pencil test which covered comparable tasks set by LMS. In addition, certain students were given detailed diagnostic interviews. A…

This paper reports the results obtained with a group of 24 14-year-old students when presented with a set of algebra tasks by the Leeds Modelling System (LMS). These same students were given a comparable paper-and-pencil test and detailed interviews some 4 months later. The latter studies uncovered several kinds of student misunderstanding that…

This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…
