The relationships between processing speed, intelligence, and school achievement were analyzed on a sample of 184 Russian 16-year-old students. Two speeded tasks required the discrimination of simple geometrical shapes and the recognition of the presented meaningless figures. Raven's Advanced Progressive Matrices and the verbal subtests of…

Attempted to replicate the pitch discrimination findings of previous research and expand them to the modality of color discrimination in a sample of 899 teenagers and adults by correlating 2 sensory discrimination measures with the general factor from a battery of 13 cognitive ability tests. Results suggest that sensory discrimination is…

Performance on the Wechsler Intelligence Scale for Children-Revised was compared for reflective and impulsive children, aged 8-11. Reflective children scored higher on the attention-concentration and visual organization subtests. There were no significant differences in verbal comprehension. (Author/GDC)

Inspection times for both auditory and visual stimuli were correlated with verbal and nonverbal intelligence. Correlations were -.3188 and -.0929 for auditory and visual inspection times with verbal intelligence, and -.2322 and -.2676 with nonverbal intelligence. Results do not support claims that inspection time is closely related to…

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

Two experiments explored the behavior of 20 Asian elephants ("Elephas aximus") in simultaneous visual discrimination tasks. In Experiment 1, 7 Burmese logging elephants acquired a white+/black- discrimination, reaching criterion in a mean of 2.6 sessions and 117 discrete trials, whereas 4 elephants acquired a black+/white- discrimination in 5.3…

Statistically significant correlations of .37 and .57 were obtained between infant recognition memory scores obtained at four to seven months and later vocabulary tests of intelligence, for 54 children tested at four and for 39 children seen at seven years, respectively. Obtained values did not vary by sex. (Author/RD)

The few studies concentrating on adult age changes in discrimination shift behavior have reported that the performance of elderly adults on such tasks is inferior to that of younger adults and, in fact, similar to that of children. To determine whether verbal labeling, which has facilitated the performance of young children, would also reduce age…
