The effect of a commercial game on children's block design scores on the WISC-R IQ test

Two experiments investigated the extent to which 10-year old children's scores on the WISC-R Block Design subtest were affected by prior experience with a specific commercial game that involved blocks and matching patterns. Experiment 1 found that 12 10-year old children who happened to have experience with the particular commercial game scored approximately three scaled score points higher on the WISC-R Block Design subtest than 24 matched children without game experience. In Experiment 2, 24 children who did not have prior experience with this particular commercial game were randomly assigned either to a Game condition (involving two 15-minute sessions with the game) or to a No-Game condition (which involved no further game experience). Children in the Game condition subsequently increased their WISC-R Block Design scores more than children in the No-Game condition. Taken together, the experiments indicate that relatively brief interactions with a commercial game can cause a significant improvement in children's performance on an IQ subtest.     

Colombian street children: gamines and chupagruesos

Through the use of participant observations and the collection of standardized psychological test scores from a sample of 56 street children, their characteristics were examined. The Kohs Block Design measured their intelligence; the Human Figure Drawing and the Bender-Gestalt tests were used to measure emotional and neurological functioning. The data indicated that their mental health was adequate, which is postulated to be the result of intense friendships between the children. Two different styles of street life are presented--the gamines and chupagruesos. Because of their public lives and because they live without parental supervision, their developmental periods have been altered. The paper illustrates how child development is dependent on societal reactions to aberrant children.     

A Follow-up Evaluation of the Houston Parent-Child Development Center: Intelligence Test Results

The Houston Parent-Child Development Center is a 2 year parent-child education program for low income Mexican-American families. Families enter the program in annual cohorts when their child is 1 year old and complete the program when the child is 3 years old. End-of-program comparisons of randomly assigned groups have demonstrated that the program has been effective in changing mothers' and children's behaviors in positive ways. This report is a follow-up evaluation of the program's effect on children's intelligence test performance at ages 4 to 6 and 6 to 9. Few program effects were found. Program children scored higher on the WPPSI Geometric Design and the WISC-R Block Design. In addition, program boys achieved higher scores on the WPPSI Information test than control boys.     

Sex differences in spatial task performance of patients with and without unilateral cerebral lesions

Two visuospatial tasks, the WAIS Block Design and the Street Gestalt Completion Test, were administered to men and women with and without unilateral cerebral lesions. These two tasks represent different categories of visuospatial functions. The Street test is a visual-perceptual gestalt task, requiring the closure of fragmented pictures, whereas Block Design is an analytical, manipulospatial task requiring rotation of spatial coordinates. For the non-brain-damaged group, the men showed a nonsignificant trend toward better Block Design performance relative to the women, whereas there was no sex-related difference in Street performance. For the brain-damaged groups, patients with right hemisphere lesions performed significantly worse than patients with left hemisphere lesions on both the Street test and Block Design, indicating that both tasks were more sensitive to right hemisphere functioning. There was, however, a significant sex X side of lesion interaction on Block Design only, with the men showing a more asymmetrical pattern of scores. These results suggest that sex differences in functional lateralization may underlie sex differences in visuospatial ability, and that sex differences in functional lateralization may be present for only certain visuospatial processes.     

Children's Other-Oriented Behaviors in Distress Situations

Children’s other-oriented behaviors in distress situations, when observed, appear to be different depending on the kind of distress situations. The authors investigated developmental differences in children’s other-oriented behaviors by comparing two distress situations: participant-caused/other-victim and other-caused/participant-victim situations. The kinds of other-oriented behaviors younger and older children engaged in were observed under an experimental setting—two tasks that involved accidentally collapsing the object the other constructed. The results showed that other-oriented behaviors were observed irrespective of age and situations. However, the developmental changes of these behaviors were different between the two situations: Older children showed more kinds of other-oriented behaviors than younger children did in the participant-caused situation, whereas no differences between ages were observed in the participant-victim situation. Other-oriented behaviors toward the victim when the participants were at fault appeared to develop during the preschool years, whereas other-oriented behaviors toward those responsible for participants’ distress appeared to be difficult for preschoolers. The developmental origin of and changes in other-oriented behaviors in cases when children are victims should be further investigated, in additional age groups, as should the influence of cultural context.     

Comparison of counseling and clinical psychology graduates on the examination for professional practice in psychology

Doctoral recipients in clinical psychology scored higher than doctoral recipients in counseling psychology on the national licensing exam, the Examination for Professional Practice in Psychology. The largest discrepancies between the 2 groups were on Subtest I (diagnosis), Subtest II (intervention), and Subtest III (research). The differences were less large for Subtest IV (professional/ethical/legal issues) and for Subtest V (social application). The authors recommend that both counseling and clinical psychology graduate students take more course work in the department of the other discipline.     

Motor and cognitive proficiency of learning disabled and normal children

Motor and cognitive skills of learning disabled (N = 32) and normal (N = 32) boys were compared on the Modified Lincoln-Oseretsky Motor Development Scale and on the WISC-R Vocabulary and Block Design subtests. Eight learning disabled and eight normal boys were tested at four age levels from 8 to 11 years. All boys were of normal intelligence. Motor and cognitive skills of the learning disabled boys were significantly below those of the normal boys and below those of the normative group. Chronological age was not a significant factor in relationship to either motor or cognitive skills. Intercorrelations indicated that in the learning disabled group Block Design, but not Vocabulary, was significantly related to motor scores at the 8- and 9-year ages. These results suggest that a common factor relating to perceptual-motor coordination and efficiency may be involved on the Lincoln-Oseretsky and Block Design subtest for young learning disabled children but not for older learning disabled children or for normal children.     

Development of catching by children in kindergarten to grade 8: a multicohort longitudinal study

The purpose of this study was to examine developmental change associated with catching by children in Grades Kindergarten through 8. Children's performance was tested on the Catching Subtest of the Ohio State University Scale of Intra Gross Motor Assessment (OSU-SIGMA). More precisely, four cohorts of boys and girls in Grades K-8 (N = 340) from 1992 to 2000: in 1992 Grades K-8, in 1994 Grades 2-8, in 1996 Grades 4-8, and in 1998 Grades 6-8. In 2000, the original Kindergarten cohort was tested again. Data, analyzed by hierarchical nonlinear modeling, yielded significant differences in mean initial status (intercept) of all three cohorts, in mean growth rate (slope) for the K-8 cohort only, in initial status of the K-8 cohort, and for participants in baseball and softball.

Verbal Fluency Deficits in Children With Specific Language Impairment: Slow Rapid Naming or Slow to Name?

This study examined aspects of verbal fluency performance of children with Specific Language Impairment (SLI) and typically developing children matched on age and Block Design scores. While children with SLI showed deficits in verbal fluency compared to their peers, they showed the same pattern of performance on phonemic compared to semantic fluency trials. Children with SLI and normally developing children also demonstrated equivalent rates of clustering and switching, measures hypothesized to reflect aspects of frontal lobe functioning, when the overall number of exemplars was taken into account. The absence of a condition by group effect supports general processing limitation accounts of SLI, while the absence of group differences on cluster size and switches supports language-based processing accounts of SLI.

Cognitive Development of Lead Exposed Children from Ages 6 to 15 Years: An Application of Growth Curve Analysis

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.

The evolution of problem and social competence behaviors during toddlerhood: A prospective population‐based cohort survey

Research in developmental psychopathology has long been preoccupied with rather broad categories of behavior, but we know little about the specific behaviors that comprise these categories. The objective of this study was to: (a) estimate the prevalence of problem and social competence behaviors in the general population of children at 17 months of age, and (b) describe the continuity and discontinuity in the degree to which children exhibit these behaviors between 17 and 29 months of age. The results show that frequent problem behaviors are not typical of children under two years of age. Further, the results suggest that it is possible to distinguish between different types of problem behaviors before two years of age. In addition, the results show that gender differences in some problem behaviors are already present before two years of age, and increase in magnitude during toddlerhood. Finally, the results show that interindividual differences in problem behaviors observed before two years of age are stable. The predictive accuracy of frequent problem behaviors in children at 17 months of age was limited, however, with often a majority of toddlers not behaving this way a year later. Overall, our results suggest that toddlerhood represents a critical period when behavioral and emotional problems of potentially clinical significance emerge. Pediatricians should routinely ask parents to report the frequency of their young children's problem behaviors during child health supervision visits so that children whose frequent problem behaviors persist over time can be identified and possibly referred for treatment.     

An exploration into the creative abilities of children with ADHD

The purpose of this study is to explore whether ADHD is associated with high creative ability. Sixty-seven children, ages 10 to 12 (33 ADHD and 34 controls) completed the Torrance Tests of Creative Thinking (TTCT), Maier's Two-String Problem, and the Block Design and Vocabulary subsets of the Wechsler Intelligence Scale for Children (WISC-III). The results show that there is no significant difference between the ADHD group's and control group's performance on either the TTCT, Maier's Two-String Problem, or WISC-III, suggesting that children diagnosed with ADHD are no more creative than children without the diagnosis.     

Preservation of implicit memory in adult children of alcoholics

The authors investigated implicit memory in 21 adult children of alcoholics (ACAs) and 24 control individuals (all college undergraduates) who performed a serial reaction time task (SRT) to evaluate their implicit memory performance and their formation of new associations. Each group was presented with 5 blocks of 100 trials per block in which Blocks 1-4 contained a 10-item repeating sequence; Block 5 was a pseudo-random sequence. The latency difference between Block 4 and Block 5 presumably measure implicit memory. The amount of implicit memory did not differ (in ms) between the ACAs (M = 55 ms) and the controls (M = 67 ms). Implicit memory (at least as measured by the SRT task) appears to be preserved in ACAs.     

Developmental regression in autism spectrum disorders

The occurrence of developmental regression in autism is one of the more puzzling features of this disorder. Although several studies have documented the validity of parental reports of regression using home videos, accumulating data suggest that most children who demonstrate regression also demonstrated previous, subtle, developmental differences. Counter to clinical intuition, the earlier development of social, language, and attachment behaviors followed by regression does not seem to support later recovery of skills or better developmental outcomes compared to children who never had speech or typical social responsivity. In fact, this regressive group may have somewhat greater developmental impairment than the nonregressive group, though the two groups do not appear to present different behavioral phenotypes. Although autism is not the only condition in which regression occurs, it appears to be the most frequent condition. Other disorders that demonstrate an early regression with no known etiology include total blindness from birth and childhood disintegrative disorder, both of which demonstrate behavioral relations to autism. In addition, two biological conditions with known etiologies also involve regression with some behaviors resembling autism behavioral phenotype: Rett syndrome (a genetic disorder; see Glaze, this issue) and Landau-Kleffner syndrome (see McVicar and Shinnar, this issue), which involves a seizure disorder.     

Block design as a measure of everyday spatial ability: a study of ecological validity

This study investigated the effectiveness of the WAIS-R Block Design subtest to predict everyday spatial ability for 65 university undergraduates (15 men, 50 women) who were administered Block Design, the Standardized Road Map Test of Direction Sense, and the Everyday Spatial Activities Test. In addition, the verbally loaded National Adult Reading Test was administered to assess whether the more visuospatial Block Design subtest was a better predictor of spatial ability. Moderate support was found. When age and sex were accounted for, Block Design accounted for 36% of the variance in performance (r = -.62) on the Road Map Test and 19% of the variance on the performance of the Everyday Spatial Activities Test (r = .42). In contrast, the scores on the National Adult Reading Test did not predict performance on the Road Map Test or Everyday Spatial Abilities Test. This suggests that, with appropriate caution, Block Design could be used as a measure of everyday spatial abilities.     

Children with Autism and Their Friends: A Multidimensional Study of Friendship in High-Functioning Autism Spectrum Disorder

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n = 15), and were matched on SES, receptive language vocabulary, child age, and gender (each study group included one girl). Multidimensional assessments included: individual behaviors of target children and observed child-friend interactions during construction and drawing scenarios; target child's and friend's self-perceived mutual friendship qualities; and mother-reported characteristics (friendship's duration/frequency; friend's age/gender/disability status). Overall, children with HFASD displayed a number of differences on individual and dyadic friendship measures. Both age and verbal abilities affected friendship behaviors. Children with HFASD and their friends perceived friendship qualities similarly, suggesting that preadolescents with HFASD have capacities for interpersonal awareness. Between-group similarities also emerged on several complex social behaviors, suggesting that friendship follows a developmental trajectory in autism and may enhance social interaction skills in autism.
