Evaluation of the validity of the Wechsler Intelligence Scale for Children--Third Edition comprehension and picture arrangement subtests as measures of social intelligence

Clinical lore suggests that the Wechsler Intelligence Scale for Children--Third Edition (D. M. Wechsler, 1991) Comprehension and Picture Arrangement scores may be used as indices of social intelligence. This study evaluated this supposition by comparing these subtest scores with mother- and teacher-reported social functioning in 142 children with ADHD and 30 control children. After general intelligence was partialled out, the Comprehension subtest related to some aspects of social functioning, but the clinical significance of this was limited. The Picture Arrangement subtest was unrelated to social functioning, once general intelligence was controlled. These findings were consistent across study groups.     

An investigation of somatic anxiety and intelligence in children using the Kaufman-ABC and an Apple IIe program measuring heart rate

Somatic anxiety during intelligence testing was examined for 43 children in Grades K through 5 by assessing each child's heart rate with an Apple IIe computer program during an administration of the Kaufman-ABC. Heart rate (a measure of somatic anxiety) decreased steadily during the course of the test administration, except for an increase when the one timed subtest (Triangles) was administered. Heart rate during each separate subtest did not correlate significantly with performance on any task. Implications of these preliminary findings are discussed.     

WASI profile variability in a sample of psychiatric inpatients

This study examined the variability of Wechsler Abbreviated Scale of Intelligence profiles using the subtest range and profile variability index in a sample of 70 psychiatric inpatients. The subtest range and profile variability index were correlated .93 (p<.001), indicating that either measure may be used to assess profile variance. Comparison of profile variability on this abbreviated scale with other Wechsler intelligence scales in similar populations suggests that variability measures are not comparable across the tests.     

THE BRITISH ABILITY SCALES SPEED OF INFORMATION PROCESSING SUBTEST: WHAT DOES IT MEASURE?

Summary . Recent theory and research has focused on the relationship between speed of performing elementary cognitive operations and general intelligence. The developers of the British Ability Scales (BAS) included the Speed of Information Processing (SOIP) subtest as a measure of mental processing speed. To test the validity of the SOIP subtest, a group of 12-year-old children were given the BAS short-form, including the SOIP subtest, and a series of electronically timed reaction time (RT) tasks. Correlations between RT and SOIP were higher than correlations between RT and other BAS subtests, suggesting convergent and discriminant validity. A hierarchical factor analysis of the data shows that the BAS SOIP subtest is related more to speed of apprehension (RT) than to speed of making the motor response, or movement time (MT).     

Ego development and intelligence in a psychiatric population: Wechsler subtest scores

The relationship between Loevinger's measure of ego development and the Wechsler Intelligence Scales subtest scores was investigated in 91 adolescent and young adult psychiatric inpatients. Correlations with Verbal IQ and verbal subtests in general were positive and significant. The correlation with the Comprehension subtest was the highest and remained significant when Full Scale IQ was partialled. Post-conformists obtained the highest mean scores on Picture Arrangement; however, there was no difference among the lower stages on this subtest. The results lend support to a social reasoning component of ego development.     

Speed of emotional information processing and emotional intelligence

The present study aimed to investigate the relationship between the speed of emotional information processing and emotional intelligence (EI). To evaluate individual differences in the speed of emotional information processing, a recognition memory task consisted of two subtests similar in design but differing in the emotionality of the stimuli. The first subtest required judgment about whether an emotional facial expression in the test face was identical to one of the four emotional expressions of the same individual previously presented. The second subtest required deciding whether the test face with a neutral emotional expression was identical to one of the four neutral faces of different individuals previously presented. Mean response latencies were calculated for “Yes” and “No” responses. All latencies were correlated with other measures of processing speed such as discrimination time and time of figure recognition. However, the emotional expression recognition subtest was hypothesized to require the processing of emotional information in addition to that of facial identity. Latencies in this subtest were longer than those in the face recognition subtest. To obtain a measure of the additional processing that was called for by the emotionality of the stimuli, a subtraction method and regression analysis were employed. In both cases, measures calculated for “No” responses were related to ability EI, as assessed via a self‐report questionnaire. According to structural equation modeling, there was a moderately negative association between latent EI and the latency of “No” responses in the subtest with emotional stimuli. These relationships were not observed for “Yes” responses in the same subtest or for responses in the subtest with neutral face stimuli. Although the differences between “Yes” and “No” responses in their associations with EI require further investigation, the results suggest that, in general, individuals with higher EI are also more efficient in the processing of emotional information.     

Supplementary WMS-III tables for determining primary subtest strengths and weaknesses

It is common practice to evaluate the age-adjusted subtest scores from the Wechsler intelligence scales to determine strengths and weaknesses within a profile. The Wechsler Memory Scale-III (WMS-III; D. Wechsler, 1997a) represents a significant improvement over its predecessors and, for the first time, provides age-adjusted subtest scores for interpretation, just as the Wechsler intelligence scales have done for 60 years. It is reasonable to assume that examiners will evaluate the WMS-III subtest profiles for strengths and weaknesses. However, the WMS-III Administration and Scoring Manual and the WAIS-III-WMS-III Technical Manual (The Psychological Corporation, 1997) provide no assistance for accomplishing this goal. Data from the WMS-III standardization sample, as described in the WAIS-III-WMS-III Technical Manual, were used to develop tables for determining both confidence levels and infrequency of differences between individual subtest scores and the means of 5 subtest combinations that may be clinically relevant for individual cases.     

The Tromsø Social Intelligence Scale, a self-report measure of social intelligence

Social intelligence is a construct that not only appeals to laymen as a relevant individual difference but also has shown promising practical applications. Nevertheless, the use of social intelligence in research and applied settings has been limited by definitional problems, difficulties in empirically differentiating social intelligence from related constructs, and the complexity of most existing measures of social intelligence. The goal of the present research was to address some of these obstacles by designing a multi‐faceted social intelligence measure that is short and easy to administer. Three studies were conducted to develop and validate the Tromsø Social Intelligence Scale (TSIS). Study 1 examined professional psychologists’ interpretations of social intelligence to derive a consensually agreed‐upon definition of the construct. In Study 2, a large pool of social intelligence items were tested, and a 3‐factor, 21‐item scale was identified. In Study 3, the stability of this measure was confirmed.     

Self-reported leadership experiences in relation to inventoried social and emotional intelligence

Leadership has both social and emotional components. Social intelligence appears to tap the social component found in leadership. Recently, emotional intelligence has surfaced as a stable individual difference variable and appears to tap the emotional component of leadership. Mayer and Salovey (1993) suggested that the emotional intelligence and social intelligence constructs overlap. This study examined the power of both emotional and social intelligence to account for variance in self-reported leadership experiences. One hundred ninety-two university students completed measures of social and emotional intelligence and a measure of leadership experiences. Regression analyses showed that both social intelligence and emotional intelligence accounted for variance in leadership experiences. Although emotional intelligence was found to account for variance in leadership, it did not add unique variance beyond social intelligence. Social intelligence appears to play a principal role in leadership.

Factor analysis of the Wechsler adult intelligence scale-revised (WAIS-R): An examination of the standardization sample

Orthogonal and oblique factor analyses were performed using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample (Wechsler, 1981). Using objective criteria, it was decided to retain two factors. Evidence for a strong general intelligence (g) factor was found from both the orthogonal and oblique rotations. Whereas the verbal IQ provided an acceptable estimate of the Verbal Comprehension factor, a purer measure was found in the form of a Verbal Comprehension Deviation Quotient containing only the Information, Vocabulary, Comprehension, and Similarities subtests. The performance IQ was found to be an inadequate measure of the Perceptual Organization factor. A Perceptual Organization Deviation Quotient, containing only the Block Design and Object Assembly subtests, was recommended as an effective alternative. Analysis of the variance components for each subtest at every age level revealed that a substantial proportion of subtests at a wide range of age levels evidence either high or intermediate levels of specific variance. These results are discussed in terms of interpreting individual subtest scores and patterns. Each of the study's major findings are compared with prior work done with the Wechsler Adult Intelligence Scale (WAIS) (Wechsler, 1955).     

Intelligence and teachers' ratings as predictors of abstract and concrete learning

This study concerned the prediction of children's learning with an individual measure of intelligence and teachers' evaluations. Eight abstract and eight concrete nouns were paired with nonsense geometric figures and presented to 60 elementary school children in a three-trial paired-associate (PA) learning task. Subjects' IQ scores on the Wechsler Intelligence Scale for Children-Revised and teachers' ratings of learning proficiency were used to predict children's performance on the PA task. Multiple correlations favored abstract learning with verbal scale intelligence, accounting for the majority of the variability. Teachers' ratings provided a surprising degree of predictive efficiency for abstract recall which was redundant with verbal intelligence.     

Kindergarten predictors of three aspects of reading achievement

Kindergarten measures of intelligence, auditory perception, visual perception, and associative learning were used to predict three aspects of reading achievement (word attack, word recognition, and comprehension) at the end of Grades 1,2, and 3 for 79 subjects. The predictability of each measure was a function not only of grade, but also of the aspect of reading achievement being predicted. Multiple correlations of the predictors tended to increase across grade levels and were highest for the comprehension aspect of reading. The Number Facility subtest of the PMA was the over-all best predictor or reading achievement. Possible reasons for this and other findings are discussed.     

The WAIS Picture Arrangement Subtest as a Measure of Anticipation

Summary

Recent research and theory has stressed the importance of future extension as a parameter in psychological development and in psychopathology. One of the primary methods for assessing future extension has been through fantasy productions to TAT cards or to story stems. Both of these methods have been useful but they are limited because they are dependent in part on verbal fluency. It has been suggested that the Picture Arrangement (PA) subtest of the Wechsler Adult Intelligence Scale assesses anticipation and planning and, as such, it provides a non-verbal measure of future extension. PA scores were found in a pilot study to have a positive and significant relationship to future extension as measured in stories told to story roots, and in the present study to future extension as measured in TAT stories.     

Intelligence and regional brain volumes in normal controls

The relationship between brain size and intelligence was examined in a large sample of healthy normal volunteers (N = 90). In addition to confirmation of the small but significant relationship between IQ and whole brain volume (r = 0.25, p < .05) using magnetic resonance imaging, regional differences were examined using a completely automated procedure to generate lobar volumes to address questions related to regional specificity and its relationship to intelligence. A significant positive relationship was found between measures of full scale IQ and frontal (r = 0.25, p < .05) and temporal (r = 0.28, p < .01) regions, although when correlations across different brain regions were tested against each other, there was no evidence of regional specificity. In addition, no laterality effects were seen. Correlations between WAIS-R subtest scores and brain regions indicated few correlations between verbal subtest scores and brain size, but several significant correlations between the performance subtest scores and frontal, temporal, parietal, and cerebellar brain regions. These results support the notion of a modest relationship between brain size and measures of global intelligence and suggest diffuse brain involvement on performance tasks which require integration and use of multiple cognitive domains.     

The role of verbal and nonverbal memory in the Family Pictures Subtest: Data from children with specific language impairment

This study examined the contribution of verbal and visual memory to performance on the Family Pictures subtest of the Children’s Memory Scale. This subtest purports to assess declarative memory functioning in the visual/nonverbal domain. A total of 115 nine-year-old children participated in this study. Fifty-eight had specific language impairment (SLI), whilst the remaining 57 were typically developing (TD), with no history of language difficulties. Results showed that the children with SLI, who had intact declarative memory for visual but not verbal information, obtained significantly lower scores on the Family Pictures subtest when compared to the TD group. Regression analyses revealed that across the entire sample, individual differences on the Family Pictures subtest was best predicted by a measure of verbal working memory. These results question whether the Family Pictures subtest can be considered a measure of visual memory in pediatric populations. These results have implications for the interpretation of scores on this subtest regarding the nature of the types of neurocognitive difficulties children may exhibit.     

Associations between cortical thickness and general intelligence in children,adolescents and young adults

Neuroimaging research indicates that human intellectual ability is related to brain structure including the thickness of the cerebral cortex. Most studies indicate that general intelligence is positively associated with cortical thickness in areas of association cortex distributed throughout both brain hemispheres. In this study, we performed a cortical thickness mapping analysis on data from 182 healthy typically developing males and females ages 9 to 24 years to identify correlates of general intelligence (g) scores. To determine if these correlates also mediate associations of specific cognitive abilities with cortical thickness, we regressed specific cognitive test scores on g scores and analyzed the residuals with respect to cortical thickness. The effect of age on the association between cortical thickness and intelligence was examined. We found a widely distributed pattern of positive associations between cortical thickness and g scores, as derived from the first unrotated principal factor of a factor analysis of Wechsler Abbreviated Scale of Intelligence (WASI) subtest scores. After WASI specific cognitive subtest scores were regressed on g factor scores, the residual score variances did not correlate significantly with cortical thickness in the full sample with age covaried. When participants were grouped at the age median, significant positive associations of cortical thickness were obtained in the older group for g-residualized scores on Block Design (a measure of visual-motor integrative processing) while significant negative associations of cortical thickness were observed in the younger group for g-residualized Vocabulary scores. These results regarding correlates of general intelligence are concordant with the existing literature, while the findings from younger versus older subgroups have implications for future research on brain structural correlates of specific cognitive abilities, as well as the cognitive domain specificity of behavioral performance correlates of normative gray matter thinning during adolescence.     

Romantic love: What’s emotional intelligence (EI) got to do with it?

The study examined the role of EI in romantic love among newlywed couples. In addition, we set out to assess to what degree outcomes depend on the specific EI measure employed, i.e., maximal performance (ability-based) vs. typical performance (self-report). In the dyadic design implemented in this research, 100 young heterosexual married couples independently completed the Mayer–Salovey–Caruso emotional intelligence test (MSCEIT), the Schutte self-report inventory (SSRI), and a vocabulary subtest of the MILTA group intelligence battery. EI, assessed via an ability and a self-report measure, showed significant ‘actor effects’, but failed to show significant ‘partner effects’, thus only partially supporting the hypothesis that EI predicts romantic love. Whereas ability-based and self-report measures show the same pattern of relationship with romantic love in dyadic assessments, the magnitudes of outcome relationships as well as the correlations of EI with verbal ability are measure-dependent. Marital partners were not correlated on EI, thus providing little evidence for assortative mating for EI.     

An investigation of Kaufman''s method for determining scatter on the WISC-R

Kaufman's procedures (Journal of Learning Disabilities, 9, 160–168, 1976) for determining intersubtest scatter on the WISC-R were investigated by means of J. M. Sattler's revised tables (Assessment of children's intelligence and special abilities (2nd ed.), Boston, Allyn and Bacon, 1982) for determining significant subtest fluctuations. Data from the standardization sample were analyzed and new normative tables for interpreting subtest scatter were produced. The results indicated that Sattler's revised tables yielded more conservative estimates of subtest scatter than those originally reported by Kaufman. McNemar chi squares indicated that, in almost every instance, a significant number of subtests switched from being significantly discrepant by Kaufman's ±3 criterion to nonsignificant by Sattler's revised values. It was concluded that Kaufman's ±3 rule of thumb is no longer defensible on any reasonable statistical grounds and that the clinician should utilize Sattler's revised table of critical values when determining whether a subtest deviates significantly from the mean Verbal or Performance scaled score. The normative tables generated in the present study should be consulted when assessing whether the overall amount of scatter observed in a particular child's profile represents “unusual” scatter.
