This study investigated the effect of preschool experience (two types of preschool: Madrasa and non-Madrasa) on the cognitive development of children in East Africa. In the three countries studied (Kenya, Uganda, and Tanzania/Zanzibar) preschool education is burgeoning and government standards are being set. This quasi experimental evaluation used…

Purpose: Using a sample of culturally/linguistically diverse children, we present data to illustrate the value of empirically derived combinations of tools and cutoffs for determining eligibility in child language impairment. Method: Data were from 95 4- and 6-year-olds (40 African American, 55 White; 18 with language impairment, 77 without) who…

Relational frame theory (RFT) explicitly suggests that derived relational responding underlies complex verbally-based cognitive performances. The current study investigated whether the ability to respond in accordance with temporal relations between stimuli was predictive of performance on the four indices of the Wechsler Adult Intelligence Scale,…

In 1989, Hallam Hurt, a neonatologist in Philadelphia, started recruiting poor inner-city women for a study of how cocaine use during pregnancy affects the developing fetus. Dr. Hurt enrolled women who had used cocaine while pregnant and balanced them against a control group of equally poor women who had not taken any drugs. Years later, when the…

A teacher is more near to students than any other during his school days. Students want to share each and every thing related to educational as well as personal matters with him. It reflects that a teacher has strong emotional bondage with students. In the light of above discussion researcher decided to carry out a research on trainee teachers to…

In this study, psychometric properties of the test of the three-mathematical minds (M3) were investigated. The M3 test was developed based on a multidimensional conception of giftedness to identify mathematically talented students. Participants included 291 middle-school students. Data analysis indicated that the M3 had a 0.73 coefficient as a…

In this meta-analysis of 75 studies on more than 3,888 children in 19 different countries, the intellectual development of children living in children's homes (orphanages) was compared with that of children living with their (foster) families. Children growing up in children's homes showed lower IQ's than did children growing up in a family…

Hartshorne and Ullman (2006 ) presented naturalistic language data from 25 children (15 boys, 10 girls) and showed that girls produced more past tense overregularization errors than did boys. In particular, girls were more likely to overregularize irregular verbs whose stems share phonological similarities with regular verbs. It was argued that…

Robert J. Sternberg often writes about a lecture-style psychology course he took as a college freshman in which he got a C. "There is a famous Sternberg in psychology," the professor told him at the time, "and it looks like there won't be another." To Mr. Sternberg, the vignette illustrates that conventional assessments do not measure all the…

Various taxonomies of Raven's Advanced Progressive Matrices (APM) items have been proposed in the literature to account for performance on the test. In the present article, three such taxonomies based on information processing, namely Carpenter, Just and Shell's [Carpenter, P.A., Just, M.A., & Shell, P., (1990). What one intelligence test…

Aims: To investigate cognitive abilities and adaptive skills in children and adolescents with myotonic dystrophy type 1 (DM1) and correlate the findings to the cytosine-thymine-guanine (CTG) repeat expansion size. Method: Cognitive level was assessed in 55 children and adolescents with DM1 (31 males, 24 females; mean age 12y 1mo, SD 5y 1mo; range…

THIS TEST WAS DEVELOPED TO MEASURE THE INTELLIGENCE OF BLIND ADOLESCENTS AND ADULTS. SIX HUNDRED AND THIRTY BLIND SUBJECTS 14 YEARS OF AGE AND OLDER WERE USED IN REFINING AND STANDARDIZING THE NONVERBAL, PERFORMANCE OHWAKI-KOHS BLOCK DESIGN TEST FOR USE BY BLIND INDIVIDUALS IN THE UNITED STATES. RESULTS INDICATED STATISTICALLY SIGNIFICANT…

A comparison of the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Kaufman Assessment Battery for Children (K-ABC) with 37 mentally retarded children revealed that the WISC-R Full Scale IQ resulted in scores significantly lower than the K-ABC Mental Processing Composite. (CL)

Examined the standard error for short forms of Wechsler's scales with deviant subjects (N=2000). Demonstrated that the standard error of estimate of a short form for the standardization sample is an excellent approximation to the standard error of a predicted IQ for a new, even markedly deviant, subject.
