On emotionally intelligent time travel: individual differences in affective forecasting ability.

In two studies, the authors examined whether people who are high in emotional intelligence (EI) make more accurate forecasts about their own affective responses to future events. All participants completed a performance measure of EI (the Mayer-Salovey-Caruso Emotional Intelligence Test) as well as a self-report measure of EI. Affective forecasting ability was assessed using a longitudinal design in which participants were asked to predict how they would feel and report their actual feelings following three events in three different domains: politics and academics (Study 1) and sports (Study 2). Across these events, individual differences in forecasting ability were predicted by participants' scores on the performance measure, but not the self-report measure, of EI; high-EI individuals exhibited greater affective forecasting accuracy. Emotion Management, a subcomponent of EI, emerged as the strongest predictor of forecasting ability.

The relationship between nonverbal intelligence and Geschwind scores in left-handed subjects.

Under psycho motor hypothesis, the relationship between left-handedness and nonverbal intelligence was studied in left-handed male and female subjects. Handedness was assessed by the Edinburgh Handedness Questionnaire; Geschwind scores (GS) were calculated for each subject. A GS of - 100 indicated consistent left-handedness. Spatial reasoning (nonverbal intelligence) was assessed by the Cattle's Culture Fair Intelligence Test. In the male and female subjects, the IQs increased for GSs from weak up to moderate left-handedness (GSs: -5 to -60), and decreased from moderate up to strong left-handedness (GSs: -60 to -100) linearly; the regression coefficient were found to be statistically significant. Weak-, and strong left-handedness both were associated with lowest scores; the highest scores were found in the subjects with moderate left-handedness (GSs: -55 to -65). It was concluded that the prerequisite for well-developed spatial reasoning should be two-sided development of the brain instead of one-sided dominance, and well functioning parallel processing between two cerebral hemispheres.

Medical and social factors associated with cognitive outcome in individuals with myelomeningocele.

The interrelationship between biological and social risk factors and cognitive outcome in individuals with myelomeningocele was examined. The Kaufman Brief Intelligence Test (K-BIT) was administered to 65 children and young adults, age range 4 to 29 during a recent clinic visit. Unshunted individuals had scores in the average range and individuals with uncomplicated hydrocephalus in the low-average range. Although the level of lesion was found to be most strongly associated with total K-BIT score, examination of subscores indicated that socioeconomic status was the factor most strongly associated with Vocabulary score. The importance of both social and biological factors in predicting cognitive outcome in this population is useful in planning intervention strategies.

Testosterone and nonverbal intelligence in right-handed men with successful and unsuccessful educational levels.

The relationship between serum total testosterone (T) concentration and fluid intelligence (nonverbal, spatial) was studied in consistently right-handed men with successful (S) or unsuccessful educational levels (NS). Hand preference was assessed by the Edinburgh Handedness Inventory. Nonverbal intelligence was measured by Cattell's Culture Fair Intelligence Test. Serum T level was determined using chemiluminescence enzyme-immunoassay on hormone autoanalyzer. There was no significant difference between the mean T levels of the S subjects and NS subjects, although S-men tended to have higher T levels than NS-men. The mean IQ was found to be significantly higher in S-men than NS-men. In the total sample (S + NS men), the correlation between T to IQ was best described by a polynomial regression (3rd order), exhibiting an inverse U-shaped regression. In S-men, the relationship between T and IQ was best described by a polynomial regression equation of the 3rd order; however, the relationship was not U-shaped, but rather a positive correlation (low T: low IQ and high T high IQ). In NS-men, there was an inverse U-shaped correlation between T and IQ (low and very high T: low IQ and moderate T: high IQ). The present data suggest that (i) very low and very high serum T concentrations may be disadvantageous, (ii) moderate T levels may be advantageous for general fluid intelligence, and (iii) a prewired cerebral organization may be essential for the T effects on cognitive abilities.

[Effect of acupuncture at early stage on prognosis of the infantile of anoxic and ischemic cerebral injury].

OBJECTIVE: To study on the effect of acupuncture at early stage on prognosis of the infantile of anoxic and ischemic cerebral injury. METHODS: One hundred and forty-eight newborns of moderate and severe anoxic and ischemic encephalopathy after acute stage were randomly divided into an acupuncture group and a control group. The acupuncture group were treated with comprehensive interference with acupuncture as main after the acute stage, and the control group with a routine infanticulture measure after acute stage and were discharged from hospital. Intelligence test was conducted in age of 3, 6, 12 and 18 months. Results The average development quotient (DQ) in the: acupuncture group in age of 6, 12, 18 months increased by 14.54, 21.46, and 24.06 points as compared with the control group, respectively. After age of 18 months, the maim rate was 7.2% in the treatment group and 33.8% in the control group with a very significant difference between the two groups (P < 0.01). CONCLUSION: The comprehensive interference with acupuncture as main at early stage can effectively promote mental and motion development, and it is effective way for improving prognosis, reducing incidence rate of sequelae and increasing life quality in the infantile of anoxic and ischemic encephalopathy.

Assessment of the long-term effects of primary radiation therapy for brain tumors in children.

One-hundred-twelve children with primary brain tumors received definitive radiotherapy between the years 1958--1979. Sixty-nine patients were alive at intervals of 1--21 years. Thirty-eight patients underwent neurologic and endocrine evaluation, psychologic and intelligence testing, and assessement for second malignancy post-treatment. A second intracranial malignancy developed in one child, for an incidence of 1.6%. Performance status was good to excellent in 89% of the patients studied. Seventeen percent of the group were mentally retarded. Behavioral disorders were identified in 39% of the patients, 59% of the mothers, and 43% of the fathers. Of the 23 patients with nonparasellar tumors, six were found to have growth hormone deficiency, including two patients with panhypopituitarism. Disability was related to age under 3 years at the time of treatment and tumor extension to the hypothalamus.

Evaluation of two brief and reliable estimates of the WAIS-R.

Performance of 200 mixed neuropsychiatric patients on the WAIS-R were compared to the summary scores for Kaufman's Brief Intelligence Test (K-BIT) and a seven subtest short form of the WAIS-R. Correlations between verbal, non-verbal, and composite of the full WAIS-R with the K-BIT were significantly lower than the correlations with the WAIS-R shore form. The percentage of cases on the short forms that fell within 5 points of the full WAIS-R was higher for the seven subtest version of the WAIS-R than the K-BIT. Specifically, Verbal, Nonverbal/Performance, and Composite/Full Scale scores on the WAIS-R short form feel within 5 points for 89%, 74%, and 92% of the cases while on the K-BIT only 52%, 40%, and 50% fell within 5 points.

The prevalence of locomotor complaints in middle age and their relationship to health and socioeconomic factors.

The prevalence and coincidence of symptoms or signs or both of degenerative changes in the back, shoulders, hips, and knees were analyzed in 575, 55-year-old residents of Malmö, Sweden, and the relationship of these complaints to smoking and alcohol habits, nervous problems, body weight, social background, intelligence test in 1938, education, job satisfaction, income, life success, employment, and occupational workload were analyzed. Back pain was the most common complaint--nearly 1/3--in men and women. Locomotor discomfort coincided more often and was more frequent in women. Overweight was related to knee and back complaints in men. Men with shoulder complaints were more often smokers. Men with knee complaints had higher levels of serum glutamyl-transferase, indicating a higher alcohol intake. Sleeping disturbances were more common in subjects with shoulder, back, and knee complaints. Subjects with moderate or heavy work loads had more locomotor complaints, particularly in the back, hips, and knees. Job dissatisfaction was the variable with the strongest independent relation to locomotor discomfort in both genders.

Ageing memory: use versus impairment.

An uncued recall technique was used to compare recall of autobiographical events by two groups of elderly volunteers of equivalent general intelligence (assessed by unadjusted scores on the AH4 intelligence test). One group lived in residential care, and the other led independent lives. Residential care subjects recalled and spontaneously rehearsed more memories from their early than their recent lives, whereas the reverse was true for the independent elderly. The effects of senile confusional states were also investigated by testing a subgroup of cognitively impaired subjects, also in residential care. Although unimpaired elderly in care produced more early than recent memories, they were still able to produce substantial numbers of recent memories. Impaired subjects produced very few memories, those they did produce were mainly early ones. Frequency of rehearsal (or reminiscence) seemed to affect the probability of elicitation of a memory. People in institutions more often rehearse memories of early events. Frequency of rehearsal is thus a function of the use which people in different situations make of their memories. Cognitive impairment due to organic neurological changes in the elderly had a characteristic effect on the abundance of recall from recent life.

When a grandiose self-image is threatened: narcissism and self-concept clarity as predictors of negative emotions and aggression following ego-threat.

Two studies examined the relation between narcissism, self-concept clarity, negative emotions, and aggression based on theoretical assumptions proposed by Baumeister, Smart, and Boden (1996). Narcissism and self-concept clarity were examined as predictors for anger, depression, and verbal aggression following ego-threat, which was operationalized by a bogus performance feedback on an intelligence test. The second study also examined the mediating effects of participants' negative emotions to provide an additional explanation for the aggressive reactions after failure. As expected, narcissism and self-concept clarity were significant predictors of negative emotions and aggression after failure. In accordance with our hypothesis, high narcissists with low self-concept clarity reacted with anger and aggression after failure, whereas less narcissistic individuals with high self-concept clarity showed feelings of depression and no aggression. The results also indicated that aggression was always directed toward the source of the ego-threatening feedback. Additionally, anger and depression could predict the aggressive response after failure but they did not mediate the relation between narcissism, self-concept clarity, performance feedback, and aggression.

Effects of chronic epilepsy on intellectual functions.

Intractable epilepsy is related to various transient and chronic brain electric and neurochemical disturbances. There is increasing evidence that long-lasting chronic epilepsy may induce secondary neuronal loss and metabolic dysfunctions. Still a matter of controversy is, however, whether cognitive abilities of patients deteriorate with increasing duration of intractable epilepsy. We present results from two independent cross-sectional studies dealing with measures of global cognitive performance in two different ways. The first study investigated in 78 patients with refractory temporal lobe epilepsy (TLE) the influence of duration of epilepsy on the difference between an estimated measure of former or pre-morbid intelligence and the current performance in an intelligence test. The second study aimed at duration of epilepsy-dependent effects on current IQ measures of 209 patients with refractory TLE. Both studies showed that the duration of epilepsy contributes to the explanation of interindividual variability in IQ measures of adult TLE patients to a higher degree than age and age of epilepsy onset. Similar to several studies on hippocampal neuronal density, hippocampal volume, and glucose metabolism, the presented cross-sectional data demonstrate that a duration of chronic epilepsy exceeding two decades is associated with worse cognitive abilities. Consequently, refractory TLE seems to induce a very slow but ongoing cognitive deterioration. It is assumed that epilepsy-related noxious events and agents exhaust the compensatory capacity of brain functions. A high cognitive reserve capacity, however, might delay the onset of deterioration.

Correlation between computed tomographic brain scan abnormalities and neuropsychological function in children with symptomatic human immunodeficiency virus disease.

OBJECTIVE: To evaluate the clinical significance of computed tomographic brain scan abnormalities observed in children with symptomatic human immunodeficiency virus disease. PATIENTS: Eighty-seven previously untreated children with symptomatic human immunodeficiency virus type 1 disease. METHODS: General levels of cognitive functioning, obtained from age-appropriate intelligence tests, and social-emotional behavior were correlated with computed tomographic brain scan abnormality ratings. RESULTS: A significant relation between computed tomographic brain scan abnormalities and cognitive dysfunction as well as aberrant behavior was found, which appeared stronger in (younger) vertically infected children compared with transfusion-infected patients. Calcifications, independent from the degree of brain atrophy, were associated with significantly greater delays in neurocognitive development. CONCLUSION: Computed tomographic brain scan abnormalities, even when mild, were of clinical significance, suggesting that human immunodeficiency virus-associated central nervous system compromise is a continuous process and that scans may be helpful at baseline in defining patients at risk and for monitoring them during therapy.

Correlates of adjudicative competence among psychiatrically impaired juveniles.

This study examines the competence-related abilities of 120 psychiatrically hospitalized male juveniles age 10 to 17 years, using the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA), the Brief Psychiatric Rating Scale-Anchored (BPRS-A), the Massachusetts Youth Screening Instrument (MAYSI), the Kaufman Brief Intelligence Test (K-BIT), and discharge diagnoses derived from file review. The findings indicate significant age-related differences across adolescence with a relatively strong performance for most of the youths on the competence measure. While intellectual and psychiatric factors were found to contribute substantially to deficits in legal decisional ability, they were modulated by age and the developmental factors associated with it. These findings, replete with caveats concerning both the dimensional structure of competence as measured by the MacCAT-CA and the interplay with the mental status and developmental factors affecting it, underscore the multifarious nature of legal decisional capacity in youths of varying ages. The relevance of these findings to the structuring of restoration services and the application of legal theory to the competence standard in juvenile court are discussed.

The cognitive outcome of full-term small for gestational age infants at late adolescence.

OBJECTIVE: To assess the cognitive and academic performance of adolescents who were born small for gestational age (SGA) at term. METHODS: A 17-year historical prospective study was done by matching neonatal data of 1758 infants to the results of the medical and intelligence assessment performed at age 17 years at the army draft board medical examination in Israel. The results of children born SGA (weight at term birth below the third percentile) were compared to those of children who were born appropriate for gestational age (AGA). RESULTS: After adjustment by a multiple linear regression analysis, the mean (+/- standard error of the mean) intelligence test scores were 103.1 +/- 2.9 versus 105.8 +/- 1.5 (P = 0.3) for the males and 100.3 +/- 2.5 versus 104.7 +/- 1.6 (P < .03) for the females. Males born SGA at term were found to have lower educational achievements (having less than 12 years of schooling or attending a vocational school) compared with the AGA group. The odds ratio for this finding after adjustment by a logistic regression analysis was 2.40 (95% confidence interval 1.07-5.39; P < .03). Intranatal events were not found to have an effect on the measured neurodevelopmental outcome. CONCLUSION: Infants born SGA at term have an increased risk for lower cognitive performance and schooling achievements than those born AGA; this result seems to be unrelated to their intranatal course.

Multidimensional health locus of control beliefs and psychological health for a sample of mothers.

Five multidimensional health locus of control (MHLC) types for 772 women whose children are enrolled in a longitudinal study of their health and development were identified. The MHLC is composed of an internal and two external dimensions (chance and powerful others). The five independent MHLC clusters were: pure internal; believer in control; pure chance; yea-sayer; and nay-sayer. Women with high scores on the three dimensions of the MHLC (yea-sayer) compared with the rest of the sample were significantly more likely to be from a lower socio-economic status, score lower on a general verbal intelligence test and higher on the Neuroticism and Lie Scales of the Eysenck Personality Inventory. They rated their overall health as significantly poorer, and reported more symptoms of depression compared with the other groups. A pure internal locus of control was strongly associated with the report of good health. Women with a strong belief in internal and powerful other loci of control were significantly more likely to have received treatment for their depression compared with other groups. Help-seeking for children's problem behaviour did not vary significantly with MHLC groups. The present study replicated five out of six MHLC types identified in an earlier study, and established the external validity of the MHLC types on measures of health status. The findings support the use of MHLC types in future research on health locus of control.

Spectrum of cognitive, behavioural and emotional problems in children and young adults with Down syndrome.

In comparison to most other groups with intellectual disability individuals with Down syndrome are at lower risk for significant psychopathology, although relative to their typically developing peers they have higher rates of behavioural and emotional problems. A total of 43 Down syndrome patients (21 females and 22 males), who ranged in age from 5.33 to 30.58 years, were examined for the presence of age-related changes in the spectrum of externalizing and internalizing problems. Intelligence tests included Hamburg-Wechsler-Intelligenz Test für Kinder III (HAWIK-III), Hamburg-Wechsler-Intelligenz Test für Erwachsene (HAWIE-R) and Kaufman-Assessment-Battery for Children, German Version (K-ABC). Behavioural and emotional problems were assessed by the the Strengths and Difficulties Questionnaire for Parents, German Version (SDQ) and the Clinical Assessment Scale for Child and Adolescent Psychopathology (CASCAP). IQ was significantly inversly related to the age of patients. Externalizing behaviours (dominant, opposing/refusing, impulsiveness, inattention and increased motor activity) were significantly higher in the 5-10 years old group, whereas internalizing behaviours (shy/insecure, low self confidence, decreased motor activity) where more prevalent in adolescents and adults (10-30 years). Possible relationships between this age-related changes and increased risks of later-onset psychopathology (depression and dementia) are discussed.

Sibsize, family environment, cognitive performance, and affective characteristics.

The study examined to what extent relationships between sibsize and the cognitive and affective chaarcteristics of children were mediated by family environments. The Alice Heim nonverbal intelligence test (AH4), the Watts Vernon English test, and the Vernon graded mathematics test were used to assess the cognitive performance of 15-year-old children (383 boys and 396 girls). The Ss formed part of a longitudinal national study of English school children. Also schedules were administered to measure children's educational and occupational aspirations, self-concepts, and attitudes toward school. From parental interviews a family environment index consisting of both distal and proximal measures was constructed. The Jackknife technique was used in the analysis to adjust significance levels. Regression surface analysis indicated that at each environment level, sibsize was related only to the English achievement of girls and boys and to the aspirations of girls. However, the shapes of the surfaces suggest that if parents create differential learning environments for different siblings then the behaviors of the siblings are likely to vary, which provides tentative support for the confluence model of sibsize influences on the behaviors of children.

Predictive value of the Bayley mental scale in the early detection of cognitive delays in high-risk infants.

One of the most elusive developmental disabilities to diagnose during infancy is cognitive delay. Although infant intelligence tests have been identified repeatedly as poor predictors of future IQ, these predictions have typically been based on interage correlations. This retrospective study examined the sensitivity, specificity, and positive and negative predictive values of the Mental Scale of the Bayley Scales of Infant Development in detecting cognitive delay (IQ < 85) among a sample of 196 high-risk, mostly low birth weight, premature infants who were assessed initially at 4 months' corrected age and followed longitudinally to between 3 and 8 years' corrected age. As hypothesized, the Bayley Mental Scale was better at correctly identifying children with future normal IQs (specificity = 91.9%) than it was at identifying infants who would later show cognitive delays (sensitivity = 38.9%). The positive and negative predictive values were 51.9% and 87.0% respectively. Results of this study support recent assertions that cognitive delay, particularly in the mildest forms, is difficult to detect during early infancy.
