Developmental psychologists have not traditionally documented the psychometric properties of their observational instruments, partly because such concepts as reliability and validity are associated mainly with paper-and-pencil tests. A multitrait-multimethod correlation matrix (MTMM) was presented as a useful method for the psychometric evaluation…

THE STIMULATION OF BRIGHT UNDERACHIEVERS WAS THE GOAL OF A PROJECT CONDUCTED IN NINE FLORIDA HIGH SCHOOLS WITH A SAMPLE OF 44 EXPERIMENTAL AND 40 CONTROL GROUP STUDENTS. BRIGHT UNDERACHIEVERS WERE DEFINED AS STUDENTS WHO HAD SCORED ABOVE THE 75TH PERCENTILE ON THE SCHOOL AND COLLEGE ABILITY TEST IN THE NINTH GRADE, BUT WHOSE GRADES AVERAGED…

A THIRD AND FINAL PHASE OF A THREE-PHASE PSYCHOLOGICAL SERVICE PROGRAM WAS COMPLETED DURING THE SUMMER OF 1967. THIS "CHILD STUDY" SERVICE WAS CARRIED OUT IN THE HEAD START CENTERS OF THE DELTA REGION OF SOUTHEAST MISSOURI. THE CHILDREN ATTENDING THE HEAD START PROGRAM WERE ABOUT EQUALLY REPRESENTED BY CAUCASIANS AND NEGROES. AN AVERAGE…

An experimental course was devised for 36 law enforcement administrators which provided for contact periods spread over eight months and a final retraining session in the 12th month. The course integrated study of the behavioral sciences and communications, executive and professional skills, speeches and informal discussion for professional…

Hypotheses about the effects of anxiety on performance in computer-assisted instruction (CAI) were formulated and then tested. High school students and college students were used in the experiments. Learning materials used were in the subjects of science, mathematics, psychology, physics, and educational research. Two settings were compared: a…

This paper repudiates Jensen's hypothesis that differences in IQ scores and scholastic achievement in Negro and white children are genetically based. Specifically, Jensen's identification of IQ scores as a measure of abstract reasoning and problem solving and of levels of ability, and his evaluation of the magnitude of the genetic component in IQ…

An adaptation of a technique devised by Mischel (1958) was used in the longitudinal study to measure delay of gratification. Adaptations involved (1) asking the child to identify the larger of two pieces of candy to facilitate comprehension of the rewards, (2) specifying a standard time limit for receipt of the delayed reward which would be…

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…

Some stochastic approximation procedures are considered in relation to the problem of choosing a sequence of test questions to accurately estimate a given examinee's standing on a psychological dimension. Illustrations are given evaluating certain procedures in a specific context. (Author/CK)

The activities of the Nucleus Testing Committee of the Madison County (Wisconsin) Schools in developing a new student testing program are discussed, and suggestions for the development of appropriate testing procedures are given. An individualized learning packet, developed by the author, using the psychological and educational modalities of…

This study determines the effect a secondary school humanities program had upon the personal-social adjustment of its students as indicated by response to selected items in a problem checklist. The Mooney Problem Checklist, Form H (1950) was administered to 936 respondents, 454 males and 482 females. Response to all items (330) in the checklist…

The Behavioral Dimensions Rating Scale was administered to both emotionally disturbed and normal students. The factor structure was found, using confirmatory factor analysis, to be invariant over these groups. Thus, the construct validity of the instrument was supported as a measure of disturbance of school age children. (Author/KS)

The rapid increase in the United States' racial and ethnic minority populations has accompanied a mental health revolution. Traditional models previously used to explain normality and abnormality are being questioned. Therefore, ways in which school psychologists can become more aware of their own cultural background, and thus provide caring,…

Korean schoolchildren referred for psychological evaluation because of behavioral/emotional problems were subjected to a battery of tests, and half of the subjects were found to need special placement, while the other half were handicapped only by English-language difficulties. The bilingual evaluation was found useful in planning individual…

Two studies (N=4,261 persons) illustrate an inverse relationship between ability level and correlations among IQ measures. Low IQ subjects showed higher correlations than did high IQ subjects. Intercorrelations of IQ subtests, intercorrelations of cognitive ability measures, and correlations of IQ with measures of cognitive ability displayed the…
