Intellectual and adaptive functioning in Sturge-Weber Syndrome

The present study examined the intellectual and adaptive functioning in a sample of children and young adults with Sturge-Weber Syndrome (SWS). A total of 80 research participants from a SWS study database underwent full neurological evaluation as part of their participation or concurrent medical care. Twenty-nine of the participants received neuropsychological evaluations. Analyses indicated no significant demographic or neurological differences between those who did and did not receive neuropsychological evaluations. Overall, the neuropsychological evaluation sample displayed significantly lower functioning relative to published normative data across domains of intellectual and adaptive functioning. Thirty-two percent of the sample displayed impaired performance (standard score ≤ 75) in intellectual functioning and 58% displayed impaired performance in adaptive functioning. Hemiparesis status independently predicted overall adaptive functioning while seizure frequency independently predicted overall intellectual functioning. Younger participants displayed significantly higher (more intact) ratings in adaptive functioning compared to older participants, specifically in overall adaptive functioning, motor skills, and community living skills. A composite measure of neurological status (SWS-NRS) incorporating seizure and hemiparesis status effectively distinguished between individuals with impaired or nonimpaired adaptive and intellectual functioning and showed promise as a screening method for identifying individuals with more involved intellectual and/or adaptive needs.     

The effects of sport dance on brain connectivity and body intelligence

Dancing is characterised by physical movement in accordance with rhythm perception. Twelve sport dancers and 12 age- and sex-matched young adults who had no dance experience (control group) were recruited. Body intelligence and brain activity were assessed in both groups using the Body Intelligence Scale (BIS) and resting state functional magnetic resonance imaging. BIS scores of dancers were higher than those of control subjects. The dancer group showed increased functional connectivity from the precentral gyrus to the right cingulate gyrus, right occipital fusiform gyrus, right inferior frontal gyrus, right medial frontal gyrus, left inferior frontal gyrus, right parietal postcentral gyrus, and right frontal lobe compared with control subjects. Sport dancers had increased body intelligence sensitivity compared with matched controls. In addition, the characteristics of dance, including physical movement in accordance with rhythm perception, might be associated with increased brain activity in the somatosensory and rhythm perception networks.     

Perceptions of the family, delinquency, and emotional adjustment among youth

This study explored the relationships between perceived family processes (parental bonding and parental discipline styles) and adolescent emotional and behavioural adjustment among a sample of youth. Respondents were 92 (53 female, 39 male) high school students, aged 13–17 years. Significant sex differences were noted regarding levels of self-reported delinquency and parental induction style. After controlling for sex, perceptions of low care and love withdrawal were significantly related to delinquency, while low care, overprotectiveness and love withdrawal were found to be related to poor well being. Structural equation modelling was used to further assess the relationships between perceptions of family life and the outcome variables. It was concluded that adolescent perceptions of family processes form a coherent and integrated network with implications for behavioural and emotional adjustment.     

Relationships between factors of intelligence and brain volume

The recent explosion of studies aimed at determining the biological basis of intelligence has revealed that cognitive ability has a strong biological substrate. This study expands on this literature by examining the relation between cognitive ability and MRI-measured brain volume and head size in a sample of adult male siblings recruited from the London, Ontario community in Canada. It was found that brain volume correlated with IQ at 0.35 (P<0.01), thus replicating the results of past studies. Corrections for restriction of range and attenuation in both this and past studies suggest that the population value of the brain volume-IQ correlation is closer to 0.50. Head size variables, with one exception, also showed the expected positive correlations with IQ. The results of a vector analysis on factor scores indicated that the more highly g-loaded a test was the more highly it correlated with brain volume (r=0.59, P<0.01). The sum of the data suggested that although brain volume (and to a lesser extent, head size) is predictive of g, fluid ability, and memory, it does not predict crystallized ability. Unexpectedly, the higher the spatial imaging loading of a test, the less its correlation with brain volume (vector correlation=−0.84, P<0.001).     

The relationship between morningness–eveningness, time-of-day, speed of information processing, and intelligence

Morningness–Eveningness refers to individual differences in circadian phase position of spontaneous sleep–wake rhythms and to subject alertness. There is some evidence indicating that performance on cognitive tasks may be influenced by Morningness–Eveningness and time-of-day. Given the potential importance of such a finding for the assessment of cognitive ability we conducted a study assessing the relationship between Morningness–Eveningness, time-of-day, and performance on the Multidimensional Aptitude Battery IQ (MAB-IQ) and Inspection Time (IT) task. Twenty male and 50 female participants classified according to their scores on the Morningness–Eveningness dimension (Horne & Östberg, 1976) were administered the MAB and IT tasks in the morning (0900 h) and in the late afternoon (1500 h). No significant effect of time of testing, and Morningness–Eveningness was observed except for the Spatial subtest of the MAB. Morning Type-participants performed significantly worse in the morning session in Spatial subtest and better in the late afternoon session and Evening Type-participants performed significantly better in the morning than in the late afternoon session. These results do not support the hypothesis that there is a reliable relationship between Morningness–Eveningness, time-of-day and cognitive ability.     

Assessing emotional processing difficulties in normotensive individuals with high and isolated blood pressure elevations

This study examined the effect of sense modality (auditory/visual) on emotional dampening (reduced responsiveness to emotions with elevation in blood pressure). Fifty‐six normotensive participants were assessed on tasks requiring labelling and matching of emotions in faces and voices. Based on median split of systolic and diastolic blood pressures (SBP and DBP, respectively), participants were divided into low BP, high BP and isolated BP groups. On emotion‐labelling tasks, analysis revealed reduced emotion recognition in the high BP than the low BP group. On emotion‐matching tasks, reduced emotion recognition was noted in high and also isolated BP group as compared to low BP group for the task that required matching a visual target with one of the four auditory distractors. Our findings show for the first time that even isolated elevations in either SBP or DBP may result in emotional dampening. Furthermore, the study highlights that the emotional dampening effect generalises to explicit processing (labelling) of emotional information in both faces and voices—and that these effects tentatively occur during more pragmatic and covert (matching) emotion recognition processes too. These findings require replication in clinical hypertensives.     

Toxic Environment of war: Maternal prenatal heavy metal load predicts infant emotional development

BackgroundPeople in war zones are exposed to heavy metal contamination deriving from new-generation weapons, in addition to exposure to psychologically traumatizing war events. Pregnant women and their children-to-be are particularly vulnerable to both biological and psychological war effects.ObjectiveThe aim of the current study was to analyse the impact of maternal prenatal heavy metal contamination on infant emotional development and to examine the potential moderating role of maternal symptoms of post-traumatic stress disorder (PTSD) in the association between heavy metal load and infant emotional development.MethodsThe participants were 502 Palestinian mothers, pregnant in their first trimester during the 2014 War on Gaza. The mothers were recruited at their delivery (T1) and followed at the infants’ age of 6–7 months (T2; N = 392). The load of five weapon-related heavy metals (chromium, mercury, vanadium, strontium, and uranium) was analysed by Inductively Coupled Plasma Mass Spectrometry (ICP/MS) from mothers’ hair samples at childbirth (T1). Assessment of maternal PTSD symptoms was based on the Harvard Trauma Questionnaire (HTQ) and infant emotional development on the Infant Behavior Questionnaire (IBQ), both reported by mothers (T2).ResultsTwo of the analysed metals, chromium and uranium, adversely predicted children’s early emotional development, indicated by decreased positive affectivity, increased negative emotionality, and problems in early orientation and regulation. Mother’s PTSD did not moderate the impact of heavy metal contamination on children’s emotional development.ConclusionsAdverse impact of war is not limited to those who experience it directly, but is passed on to future generations through multiple mechanisms. International organizations are obliged to protect parents and infants from the modern weaponry in wars.     

Cross-cultural validation of a French version of the Emotional Processing Scale (EPS-25)

IntroductionThe Emotional Processing Scale (EPS) is a self-report questionnaire consisting of 25 items designed to identify emotional processing styles and impairments. The aim was to develop a French version of the scale and to test its preliminary validity and reliability in French community and clinical samples.MethodAfter translation and back-translation, a validation study was conducted with 1176 adults [215 from a community sample, 251 undergraduate psychology students, 686 people with a range of physical health conditions (HIV, multiple sclerosis, chronic pain, leukaemia) and 24 people with bipolar disorder hospitalised for depression].ResultsThe internal reliability of the French EPS was good, with a Cronbach's alpha of .91. The five-factor structure of the original English version of the scale was closely reproduced.ConclusionsThe French EPS demonstrated good reliability and validity. Correlations with other conceptually similar scales (e.g., TAS-20, CERQ, STAXI) were as predicted. EPS scores distinguished between groups (clinical samples vs. a community sample) that would be expected to differ.
