The Relationship

AbstractIn recent years, there has been a renewed interest in the relationship between intelligence and personality. Extraversion, in particular, has been suggested to influence intelligence, but the direction of this relationship has been controversial (Wolf & Ackerman, 2005). In a young adult sample, the NEO PI-R was completed by 103 pairs of monozygotic twins, 181 pairs of dizygotic twins and 210 of their nontwin siblings. IQ data (Multidimensional Aptitude Battery) were available for approximately three quarters of this sample, and were collected at 16 years as part of an ongoing study of cognition conducted by the Queensland Institute of Medical Research. All extraversion facets were significantly influenced by genes with both additive and nonadditive genetic effects being important (heritabilities ranged from .25 for activity to .54 for warmth). While a significant correlation between the extraversion domain score and IQ was not found, the extraversion facet of excitement-seeking (E5) was significantly negatively correlated with both verbal (r = −.15) and performance (r = −.11) IQ scores. The facet of gregariousness was significantly correlated with verbal IQ only (r = −.09). The relationship between excitement-seeking and IQ was further shown to be solely due to additive genetic influences. These common genetic effects may stem from a dependence on brain dopamine, a neurotransmitter that has been implicated in both personality and cognition.

Three Factor

In this study, 140 Belgian, 227 British, and 177 Slovakian students estimated their own multiple IQ scores as well as that of their parents (mother and father) and siblings (first and second brother and sister). Various factor analyses yielded a clear three-factor structure replicating previous studies. A sex × culture ANOVA on self-ratings of three factors that underline the seven intelligences (verbal, numerical, cultural) showed culture and sex effects as well as interactions. As predicted, males rated their own overall IQ, though not that of their parents or siblings, higher than females did. Males also rated their numerical IQ, but not their verbal or cultural IQ, higher than females did. There were few culture differences but many interactions, nearly all caused by Slovakian females, who rated aspects of their own and their fathers' IQ higher than Slovakian males, while the pattern for the Belgians was precisely the opposite. Participants believed their verbal IQ was higher than their numerical IQ and their cultural IQ. Males believed their verbal and numerical IQ score to be fairly similar, though much higher than their cultural IQ, while females believed their verbal IQ the highest, followed by numerical and cultural IQ. Females also believed they were more intelligent than both parents. Overall results showed consistency in the sex differences in ratings across cultures but differences in level of estimated IQ possibly as a result of cultural demands for modesty.

Personality Construct

Alexithymia is a multifaceted personality construct related to deficits in the recognition and verbalization of emotions. It is uncertain what causes alexithymia or which stage of emotion processing is first affected. The current study was designed to determine if trait alexithymia was associated with impaired early semantic decoding of facial emotion. Participants performed the Emostroop task, which varied the presentation time of faces depicting neutral, angry, or sad expressions before the classification of angry or sad adjectives. The Emostroop effect was replicated, represented by slowed responses when the classified word was incongruent with the background facial emotion. Individuals with high alexithymia were slower overall across all trials, particularly when classifying sad adjectives; however, they did not differ on the basic Emostroop effect. Our results suggest that alexithymia does not stem from lower-level problems detecting and categorizing others’ facial emotions. Moreover, their impairment does not appear to extend uniformly across negative emotions and is not specific to angry or threatening stimuli as previously reported, at least during early processing. Almost in contrast to the expected impairment, individuals with high alexithymia and lower verbal IQ scores had even more pronounced Emostroop effects, especially when the face was displayed longer.To better understand the nature of alexithymia, future research needs to further disentangle the precise phase of emotion processing and forms of affect most affected in this relatively common condition

Iq Scores

Intelligence tests continue to be the most widely used measures of cognitive aptitudes. Performance on such measures is usually expressed as an IQ score. Popular opinion to the contrary, relatively little is known about the long term measuring of IQ scores from group verbal and non-verbal intelligence tests, especially the latter. This study shows that, below ten years of age, stability in IQ scores from group verbal tests is considerably below that for the Stanford-Binet. Non-verbal IQ scores were found to have substantially less stability than Verbal IQs.

Iq Scores

The WISC-RIQ scores of 85 children between 7 and 12 years of age taken from the inpatient, outpatient and day care facilities of a Regional Treatment Centre were compared with the expected IQ scores of the standard normal population. In addition, analysis of variance techniques were used to test for an association between IQ variables and seven operationally defined symptom subtypes taken from the child's chart. Significant differences between the clinical sample and the standard normal population were found for the distribution and means for full scale IQ and verbal IQ but not performance IQ. In addition, significant associations were found between FSIQ and the level of aggressive symptoms, and between VIQ and the level of hyperkinetic and aggressive symptom subtypes. The importance of IQ variables and in particular VIQ in understanding the nature of childhood psychiatric disorder is emphasized. The implications of these findings for educational policy are discussed.

In this pilot study, we assessed the reliability of cognitive testing for kids and adolescents ages 8-19 years of age with narcolepsy or subjective daytime sleepiness compared to healthy controls. Forty-six participants took part in the study (n=18 with narcolepsy type 1, n=6 with subjective daytime sleepiness, and n= 22 healthy controls recruited from the community). Participants completed verbal (vocabulary testing) and non-verbal intelligence quotient (IQ) tasks (block design, matrix reasoning) from the Weschler Abbreviated Scale of Intelligence- Second Edition (WASI-II) in-person or remotely in their home through a HIPAA compliant telehealth web platform with conditions counterbalanced. We found that vocabulary T-scores showed good reliability with intraclass correlation coefficient (ICC) of 0.76 (95% CI: 0.64, 0.85) between remote and in-person testing conditions. Matrix Reasoning T-scores showed moderate reliability ( ICC 0.69, 95% CI: 0.68, 0.90) and Block Design T-scores was poor between testing conditions. Bland-Altman plots showed outliers on vocabulary and matrix reasoning tasks performed better on remote assessments. Overall, the results of this pilot study support the feasibility and reliability of verbal and non-verbal IQ scores collected by telehealth. Use of telehealth to collect verbal and non-verbal IQ scores may offer a means to acquire cognitive data for pediatric sleep research through the COVID-19 pandemic and beyond.

And Performance

45 9- to 14-yr.-old right-handed boys (IQ range: 85 to 115) with learning disabilities were distributed into three groups on the basis of their WISC Verbal IQ and Performance IQ scores: the high performance-low verbal (HP-LV) group, the verbal equal to performance (V = P) group, and the high verbal-low performance (HV-LP) group. The three groups were equated for age and Full Scale IQ. The performance of these Ss on 25 measures indicated clear superiority of the HP-LV group on most measures of complex motor and psychomotor abilities, regardless of the hand employed. Although expectations involving differential hand superiority of the HP-LV and HV-LP groups were not supported, the results were considered consistent with the view that WISC VIQ-PIQ discrepancies reflect the differential integrity of the two cerebral hemispheres in older children with learning disabilities.
