Extends the available information base on intellectural aging by collecting self-report data from 100 psychologists between 45 and 64 years of age. Subjects rated changes in intellectual functions, related present changes with past expectations, and answered questions about health problems affecting intellectual functioning. The importance of…

Major research findings relevant to use of the Wechsler Digit Span subtest in psychoeducational assessment are summarized. The cognitive processes and behavioral characteristics which determine performance on Digit Span are related to complex abilities. Recommendations and implications for research and assessment practice are presented.…

Examines and comments on Logo's educational rationale in light of Piagetian theory and recent studies in information-processing psychology. Two educational problems from which Logo theory has been derived and Logo's responses to these problems are discussed. (MBR)

Techniques for constructing short forms of tests are discussed, and an example is given using the Wechsler Adult Intelligence Scale-Revised. Reliability and validity estimation equations are presented. (GDC)

The Peabody Picture Vocabulary Test Revised (PPVT-R) and the Comprehensive Tests of Basic Skills (CTBS) (reading, mathematics, and language subtests) were administered to 61 elementary school students in semi-rural Louisiana. Moderate positive correlations were found between PPVT-R scores and all CTBS subtests except mathematics computation. (GDC)

Past research has suggested memory, writing speed, and paired-associate learning rate to be important in WISC-R (Wechsler Intelligence Scale for Children Revised) coding performance. Suggested that visual perceptual factors also may be important and that coding performance in right-handed persons may be especially sensitive to integrity of the…

Describes a study done to explore the impact of socioeconomic variables on ego-attitudes in second language learners, 12-16 years of age. There were significant differences between the children of professional and the children of working class parents in IQ and vocabulary but not in inferential comprehension.(SED)

Describes three themes that have informed research on cognitive development in sub-Sahara Africa over the past 10 years: (1) extending the range of generalizability of Western theories; (2) interpreting the uniqueness of the African situation; and (3) deriving implications for social policy. (Author/AS)

Concludes that the new Slosson Intelligence Test (SIT) serves reasonably well as a quick estimate of intellectual ability but that it should not be used as an extended substitute for the more rigorous WISC-R. (FL)

The Department of Administrative Programming Services of Clemson University investigated products available in user-friendly retrieval systems. The test of INTELLECT, a natural language query system written by Artifical Intelligence Corporation, is described. (Author/MLW)

Description of several computerized tutoring systems is organized around types of knowledge any tutor must possess--subject area, student's information, and how to teach and communicate. Data and control structures of Meno-tutor are described to illustrate use of artificial intelligence to model the student, a domain, and teaching strategies. (MBR)

Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

The concurrent validity of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) was assessed against the McCarthy Scales of Children's Abilities in a sample of 39 Mexican-American preschool children from low socioeconomic status background. Results indicated some specific support for the WPPSI's concurrent validity. (Author/BS)

Adult performance on verbal analogy and classification problems was assessed in terms of outcomes of process execution. Process-outcomes measures accounted for overall performance and were related to ability. Problem forms differed in terms of which measures predicted individual differences. Common process-outcome measures showed highest…

Studies medium- and long-effects of types of placement of children of lower class families. The progeny of 28 disadvantaged women was reconstituted. Results show increase in IQ and diminuition of scholastic futures for adopted children and diminuition of IQ and increase in scholastic failure among children reared by mother in disadvantaged…
