Noting the lack of research comparing the Test of Nonverbal Intelligence (TONI) with other measures of intelligence, a study was conducted to ascertain concurrent validity. The TONI was compared to the Slosson Intelligence Test for Children and Adults (SIT) and the Wechsler Intelligence Scale for Children--Revised (WISC-R). Subjects, 43 males and…

Factors extracted from the normative samples of the Wechsler Intelligence Scale for Children Performance Scale (WISC PS), Wechsler Intelligence Scale for Children-Revised Performance Scale (WISC-R PS), and Hiskey Nebraska Test of Learning Aptitude (HNTLA) are compared to factors emerging from deaf normative samples on these nonverbal intelligence…

Administered the Peabody Picture Vocabulary Test-Revised, Peabody Picture Vocabulary Test, and Wechsler Adult Intelligence Scale-Revised to mildly retarded adults (N=21). Results indicated that the revised Peabody tended to yield significantly lower estimates of functioning than did the other measures. (Author/LLL)

A nonverbal assessment procedure was designed to characterize cognition using a Piagetian framework with six autistic children, five echolalic and one nonverbal, ranging in age from 4.8 to 15.2. All six children evidenced competence beyond sensorimotor Stage VI, and demonstrated cognitive functioning between the periods of early preoperational and…

Reports three experiments which examined kindergarteners' ability to conserve number in response to three forms of questioning: nonverbal, standard, and control. There was no indication that a full mastery of conservation could be elicited earlier by the nonverbal procedure. (Author/JMB)

A normative typology was developed and applied using multivariate profile analysis of subtest scores of the Universal Nonverbal Intelligence Test (UNIT) standardization sample. The results yielded a seven-profile cluster solution for the Extended Battery, and a six-profile cluster solution for the Standard Battery. Additionally, the results lend…

The cube imitation test was developed by Knox (1913) as a nonverbal test of intelligence. Many variants show satisfactory reliability, but performance is correlated both with Verbal IQ and with Performance IQ. Performance is impaired by cerebral lesions but unrelated to the side of lesion. Examinees describe both verbal and visuospatial…

The Test of Nonverbal Intelligence-3rd Edition (TONI-3) and the Analogic Reasoning (AR) subscale of the Universal Nonverbal Intelligence Test (UNIT) were administered to 35 individuals with autism to determine whether real-world-knowledge deficits affected intelligence scores. The 2 tests are similar in format; however, the TONI-3 includes only…

Lynn [Lynn, R., 2002. Sex differences on the progressive matrices among 15-16 year olds: some data from South Africa. "Personality and Individual Differences 33," 669-673.] proposed that biologically based developmental sex differences produce different IQ trajectories across childhood and adolescence. To test this theory we analyzed the…

Just as the Raven Progressive Matrices Test was uncorrelated in this sample with other measures of intelligence so was it much less well predicted from several information processing measures. It was found that verbal performance, indicated by a vocabulary score, was highly predictable from measures of information processing. While preserving…

Graphic design decision-makers assume that graphic design preferences vary among demographic groups. This assumption was tested on a population of 200 college students reflecting a valid demographic distribution in four categories: sex, community size, income, and occupational status. Subjects were asked to rank order their preferences for four…

Ten test films were developed to measure aspects of children's visual perception which are difficult to assess through conventional paper and pencil tests. The film medium was selected because it allows the presentation of temporal, as well as spacial, aspects of the stimuli. Four areas of perceptual performance covered in the films are: (1)…
