Reversible memory disturbance and intelligence impairment induced by long-term anticholinergic therapy.

It is controversial whether long-term anticholinergic therapy (AC-T) can cause short-term memory disturbance, long-term memory disturbance or intelligence impairment. Ninety patients with Parkinson's disease were examined prospectively to clarify the existence of memory and intelligence impairment induced by long-term AC-T. Neuropsychological tests detected eight patients with at least one of four types of deficits; intelligence impairment in four patients, verbal delayed recall impairment in eight, verbal short-term memory disturbance in five, and verbal long-term memory disturbance in six. Two types of verbal memory disturbance (short-term one and long-term one) appeared with double dissociation, suggesting that there may be an independence between the two types of verbal memory system. Older patients were more prone to suffer from these reversible deficits. Moreover, all of the patients who resumed AC-T, showed recurrence of the deficits acutely. These observations should indicate the tight relation between long-term AC-T and neuropsychological deficits.

Acute hypoglycemia in humans causes attentional dysfunction while nonverbal intelligence is preserved.

OBJECTIVE: Experimentally induced hypoglycemia in humans causes progressive but reversible cognitive dysfunction, but it is not known to what extent neuropsychological tests index abilities of cognitive functioning that are important in everyday life. This study examines the effects of acute insulin-induced hypoglycemia on attention and intelligence in nondiabetic humans. RESEARCH DESIGN AND METHODS: A hyperinsulinemic glucose clamp was used to achieve controlled euglycemia (4.50 [0.22] mmol/l) and hypoglycemia (blood glucose 2.59 [0.19] mmol/l) in 20 healthy volunteers. Subjects were studied on two occasions in a counterbalanced order. During each study condition, subjects completed parallel tests of cognitive function. Cognitive function was assessed by the Test of Everyday Attention and Raven's Progressive Matrices. RESULTS: Hypoglycemia induced a significant deterioration in tests sensitive to both visual and auditory selective attention. During hypoglycemia, attentional flexibility deteriorated and speed of information processing was delayed. Sustained attention was preserved and intelligence scores did not deteriorate during hypoglycemia. CONCLUSIONS: During hypoglycemia, a significant deterioration occurs in attentional abilities, whereas fluid intelligence is preserved. On the basis of these results, it can be surmised that many complex attention tasks relevant to everyday life are impaired during moderate hypoglycemia.

Relationship of role identification, self-esteem, and intelligence to sex differences in field independence.

The relationships among perceptual field independence, biological sex, sex-role identity, self-esteem, and intelligence were explored. Tests measuring these variables were administered to 50 male and 50 female volunteers. The results, obtained by standard multiple regression and analysis of covariance procedures, indicate that (a) males are significantly more field-independent than females, (b) regardless of biological sex, subjects with relatively masculine role-identities are more field-independent than subjects with relatively feminine role-identities, (c) self-esteem is not significantly related to perceptual style, and (d) although intelligence has a significant positive relationship to perceptual field independence, intelligence does not account for the sex differential or for the role sex-identification plays in perceptual style.

Prediction of adults' reading performance as a function of auditory and visual cognitive styles and intelligence.

120 students were administered the Auditory Cognitive Styles Test and the Matching Familiar Figures Sequential Presentation Test to assess cognitive style. Estimates of intelligence were based on the California Test of Mental Maturity. Performances were used to predict achievement on the Diagnostic Reading Test: comprehension, vocabulary, and total reading. Canonical correlation indicated an over-all relationship between the cognitive style variables and intelligence in the predictor set and the three reading measures of the criterion set. Only intelligence and errors on the auditory test contributed significantly to the variance of the reading measures. Importance of auditory factors in understanding adults' reading is supported.

Effects of listeners' experience on two measures of intelligibility.

10 speech-language pathologists with extensive experience in judging speakers' intelligibility and 10 control subjects with no such previous experience provided written identification and magnitude-estimation scaling judgments of the intelligibility of nine audiotaped speech samples. Analysis indicated no significant main effect for experience on either the written identification or the magnitude-estimation scaling tasks. Implications for the continued use of magnitude-estimation scaling as a measure of speech intelligibility are discussed.

Intelligibility of speech in children with Down syndrome in natural settings: parents' perspective.

Data collected from 937 parent questionnaires regarding intelligibility of speech in children with Down syndrome were analyzed. Intelligibility was a wide-spread problem. Parents reported evidence of difficulties classified as oral motor skills, motor programming skills, and specific speech skills. Children experienced greater difficulty with sentences and in conversation than with single words. Intelligibility problems were more frequent when the child was conversing with unfamiliar adults. The implications of these findings for clinical assessment and remediation are discussed.

Relations between creativity and intelligence among Malaysian pupils.

This paper describes an empirical study of the relation between creativity and intelligence of 397 Malaysian secondary school pupils. The Torrance Tests of Creative Thinking, Figural Form A and Verbal Form A (Malay Language version), and the Cattell Culture Fair Intelligence Test were administered to 181 boys and 216 girls from five secondary schools located in the urban and suburban areas of Kuala Lumpur and Petaling Jaya in Malaysia. Analysis indicated that scores on verbal creativity were related to intelligence while those on figural creativity were not.

Sex differences in self-estimates of lay dimensions of intelligence.

260 participants rated themselves on 12 items that made up the three types of intelligence as noted by Sternberg, et al. in 1981. There were sex differences on two of the three standardized scores with men rating themselves higher than women on practical and verbal intelligence. This confirms previous studies of sex differences in the ratings of over-all (g) and multiple intelligences.

Sex differences in the personal conceptions of intelligence: particularities of the Portuguese cultural context.

Several empirical studies have implicated helplessness as a problem in girls' lack of achievement, generally associated with static conceptions of intelligence. Yet, two studies aiming to explore sex differences in personal conceptions of intelligence, carried out with Portuguese samples of 222 and 2,106 subjects, respectively, using a 15-item rating scale to measure personal conceptions of intelligence adapted for Portuguese adolescents (11 to 17 years old), did not find sex differences, suggesting that certain specific characteristics of the Portuguese cultural context and its underlying socialization processes may have altered the expected kind of differentiation. Researchers should investigate whether success is not stereotypically attributed to male role norms and the importance of arousal of standards of achievement for women in the Portuguese culture.

Judgments about length, weight, and width covariation as a function of intelligence and depth of processing in elementary school children: a preliminary study.

28 elementary school students were assessed for intelligence, then blindfolded and asked to explore objects manually before rendering judgments about how weight and width were related to length. Exploration time for each object was hypothesized to reflect the level of processing engaged in by the participants. It was also predicted that more intelligent children would produce the most accurate judgments. Inconsistent with the predictions, analysis indicated that children of higher intelligence did not produce the most accurate judgments. However, longer exploration times reflected a tendency to refrain from endorsing a negative correlation between length and width. Depth of processing is, therefore, presumed to aid in reasoning about covariation.

Relation of perceived emotional intelligence and health-related quality of life of middle-aged women.

This study examined the relationship between perceived emotional intelligence and health-related quality of life in middle-aged women. 99 middle-aged Spanish women, who studied in two adult schools, volunteered to participate. 49 were premenopausal and 45 were postmenopausal. These women completed the Trait Meta-Mood Scale and Health Survey SF-36. Scores were analyzed according to social, physical, and mental health, menopausal status, and scores on perceived emotional intelligence. Then, the data regarding the mental and physical health of the premenopausal and postmenopausal women were compared after controlling for age. No associations between menopausal status and health-related quality of life were found. Perceived skill at mood repair was significantly associated with scores on health-related quality of life in these middle-aged women. These findings provide empirical evidence that aspects of perceived emotional intelligence may account for the health-related quality of life in midlife including social, physical, and psychological symptoms.

Correlations for the Vineland Adaptive Behavior Scales with Kaufman Brief Intelligence Test in a forensic sample.

People with an intellectual disability are over-represented in the criminal justice system in many western countries. Identifying accused persons with intellectual disability is important if they are to receive protections available under the law. Accurate diagnosis is also relevant for correctional administrators, probation and parole services, and community services. Diagnosis of intellectual disability must be made on the basis of both cognitive skills (intelligence) and adaptive behavior. In this study, the Kaufman Brief Intelligence Test assessed intelligence, and the Vineland Adaptive Behavior Scales assessed adaptive behavior, through self-report. Tests were administered to 150 offenders, ranging in age from 13 to 53 years, in Australian prisons, juvenile detention centers, legal aid offices, and probation services. Pearson product-moment correlation coefficients calculated among all subtests and between total scores were significant. ROC curve analyses demonstrated that performance on each effectively predicted a standard score of less than 70 on the other one.

Development and application of a brief measure of emotional intelligence for vocational high school teachers.

To develop a psychometrically sound, self-report measure of emotional intelligence and examine the scores of vocational high school teachers by sex and age, 375 Taiwanese vocational high school teachers (186 men, 189 women) completed the 25-item Emotional Intelligence Scale of five domains: Self-awareness, Managing Emotions, Self-motivation, Empathy, and Handling Relationships. Analysis indicated that these teachers reported higher scores on Self-awareness and Empathy but slightly lower on Managing Emotions. The women gave higher self-ratings on Self-awareness and Empathy than the men. There were also significant differences across age groups on Self-awareness, Self-motivation, Empathy and the Total score for the Emotional Intelligence Scale.

Educational attainment, intelligence, interstate migration, and suicide rates in the United States: rejoinder to Abel and Kruger (2005).

Abel and Kruger (2005) reported a negative association of educational attainment and suicide rate across the United States. Given strong links between intelligence and educational attainment, this appears to be inconsistent with positive associations of intelligence and suicide rate reported in several other geographical studies. However, the apparent inconsistencies may reflect interstate migration within the U.S. adult population. Testing this hypothesis showed that interstate migration was more strongly related to state suicide rates than educational attainment. Thus, the different results obtained by Abel and Kruger could reflect migration effects, which for the U.S. might render adult-age indicators of educational attainment inappropriate to reflect regional variation in intelligence by place of birth.

Effects of whitening and peak-clipping on speech intelligibility in the presence of a competing message.

The purpose of this experiment was to determine the effects of peak clipping on speech intelligibility when both a target speech and a competing message were simultaneously peak-clipped. A competing message composed of 5 talkers was electrically mixed with CNC discrimination words. This composite signal was presented to normally hearing subjects in three ways: unmodified, whitened, and whitened and peak-clipped. Discrimination functions were obtained for the CNC material by varying the signal-to-competition ratio. Under these conditions, essentially identical discrimination functions were yielded by the unmodified and whitened speech, whereas substantially reduced discrimination scores were obtained with the whitened/clipped speech. These results would suggest that speech intelligibility is reduced by whitening and peak clipping when more than one talker is present. This is true even though earlier studies have shown that whitening and peak clipping do not reduce speech intelligibility when only a single talker is present. Such a finding has implications for wearable amplification.

Factor analysis of the Luria-Nebraska Neuropsychological Battery: IV. Intelligence and Pathognomonic Scales.

This paper examined the factor structure of the Luria-Nebraska Neuropsychological Battery Scales Intelligence and Pathognomonic. The subjects for the study were 270 patients, including 90 normal patients, 90 psychiatric patients, and 90 neurological patients. A principal factor analysis with communalities on the diagonal and iterated to the most ideal solution was used, followed by rotation to the simplest factor structure. The analysis yielded 4 subfactors for each of the two Luria scales. On the Intelligence scale, factors were general verbal intelligence, arithmetic, a frontal verbal factor, and a right frontal sequencing factor. Analysis of the Pathognomonic scale yielded a simple perceptual/expressive factor, a construction speed factor, a basic visual/spatial factor, and a higher cognitive factor. These results were generally in accord with Luria's theories.

Topography of human intelligence across race: factorial comparison of black-white WAIS-R profiles for criminal offenders.

Comparison of intellectual functioning across racial groups is an important scientific issue with broad interdisciplinary implications. A large random sample (N = 275) of Black and White incarcerated individuals were studied to evaluate the topography of intelligence across race. Principal factor analyses yielded the general intelligence-g factor along with specific Verbal Comprehension and Perceptual Organization dimensions. All three of these structural components were highly congruent between Whites and Blacks. Theoretical implications of these data include: (1) evidence of qualitatively equivalent intellectual functioning across race, (2) justification of a verbal-performance dichotomy of adult intelligence across racial groups, and (3) support for construct validity of adult intellectual assessment across race.

Relationships between verbal intelligence, educational level and reconstitution of linguistic messages in schizophrenia.

The authors studied the influence of educational and verbal intelligence levels on a linguistic messages reconstitution test with schizophrenics. The two studies undertaken showed significantly lower sentence completion test scores for schizophrenics than for control subjects matched for verbal intelligence, educational level, age and sex. There appears to be an alteration of the cognitive processes underlying the processing and reconstitution of simple messages. This alteration is neither affected by educational level nor verbal intelligence level.
