Confidence intervals for the 80, 85, 90, and 95 percent levels of confidence are presented for the Peabody Picture Vocabulary Test-Revised (PPVT-R) using the estimated true score and obtained score based methods. Separate tables are provided for ages 2-1/2 to 18 and ages 19 and above. (Author/VW)

By comparing the profile of "g" loadings for a set of psychometric test scores, it is shown that general intelligence is related to timed performance measures from perceptual-motor tasks, more strongly on more complex tasks. The profile of the "g" loadings was predictable from the response-time (RT) psychometric test time correlations for four RT…

Analysis of Wechsler Intelligence Scale for Children-Revised protocols for identified gifted, high IQ, and average children (total N=599 and ages 5-16) identified a four-factor solution for the gifted sample (Perceptual Organization, Verbal Comprehension, Acquisition of Knowledge, and Spatial Memory). Results suggested gifted children process…

Concludes that intelligence scores are consistently lower for adults who are heavy television viewers. (FL)

This study is a concurrent validation of Level II of the Wide Range Achievement Test-Revised (WRAT-R) using the Wechsler Adult Intelligence Scale (WAIS) Verbal, Performance, and Full Scale IQ scores as criterion measures. Forty-five subjects were administered the WAIS-R and WRAT-R and their scores correlated. (Author/LMO)

Reports on the relatively new field of artificial intelligence and its relationship to vocational education. Compares human intelligence with artificial intelligence. Discusses expert systems, natural language technology, and current trends. Lists potential applications for vocational education. (CH)

This article examines the feasibility of developing expert systems for use in education. Some intelligent computer-assisted instruction systems have been developed to teach or tutor various subjects. Development of expert systems is in the prototype stage. Difficulties of systems development are discussed. (MT)

Examines the past, present, and future status of Artificial Intelligence (AI). Acknowledges the limitations of AI but proposes possible areas of application and further development. Urges a concentration on the unique strengths of machine intelligence rather than a copying of human intelligence. (ML)

Seventeen mildly retarded adolescents who participated in an Instrumental Enrichment program which stresses cognitive and metacognitive processes demonstrated significant gains in measured IQ following intervention and at a 6-month followup. Control Ss maintained or declined in intelligence level. (CL)

The controversy over whether or not machines can think has attracted the attention of philosophers, psychologists, neurologists, computer scientists, and writers of science fiction. Various topics and issues related to this controversy are discussed, including turing machines and the relationship between computer history and mathematical…

Describes expert systems which are computer programs which use inference schemes to apply generalized human expertise to the facts of a specific case. Basic concepts, potentials and implications are presented along with the issues involved in their development and use. A simple expert system, written in BASIC, is included to illustrate the…

Responses of high IQ students and moderate IQ students to a set of questions about friendships were compared. Ss preferred friends of their own sex. More high IQ Ss reported their friends to be older than themselves, that they did not have enough friends, and that being smart made it harder to make friends. (CL)

Children with visual impairments who participated in a 10-year survey were compared with peers on measures of intelligence, reading, mathematics, and sporting ability. Results are consistent with earlier findings of increased intelligence among Ss with myopia and slightly reduced intelligence among Ss with amblyopia. It was concluded that the…

Twelve elementary children talented in music and 12 talented in fine arts were matched with controls and given tests of personality, intelligence, verbal fluency, and an interest questionnaire. Despite little difference in general intelligence or reported development for the two groups, differences were found in self-confidence and home…

Argues that, although expert systems--which are supposed to give users all the advantages of consulting with human experts--can be useful for medical diagnosis, where tests tend to be reliable, they can be hazardous in such areas as psychological testing, where test reliability is difficult to measure.
