Abstract: Several commentators have suggested that the attractiveness of average facial configurations could be due solely to associated changes in symmetry. If this symmetry hypothesis is correct, then averageness should not account for significant variance in attractiveness ratings when the effect of symmetry is partialed out. Furthermore, changes in attractiveness produced by manipulating the averageness of in idual faces should disappear when all the images are made perfectly symmetric. The experiments reported support neither prediction. Symmetry and averageness (or distinctiveness, the converse of averageness) made independent contributions to attractiveness (Experiments 1 and 2), and changes in attractiveness resulting from changes in averageness remained when the images were made perfectly symmetric (Experiment 2). These results allow us to reject the symmetry hypothesis, and strengthen the evidence that facial averageness is attractive.

Abstract: Little is known about how sex influences functional brain maturation. The current study investigated sex differences in the maturation of event-related potential (ERP) litudes during an auditory oddball task (N = 170 age = 6-17 years). Performance improved with age. N200 litude declined with age: parietal sites showed earlier development than temporal and frontal locations. Girls showed greater bilateral frontal P300 litude development, approaching the higher values observed in boys during childhood. After controlling for age, right frontal P300 litude was associated with reaction time in girls. The findings demonstrate sex differences in ERP maturation in line with behavioral and neuroimaging studies.

Abstract: Background: Evidence suggests that gamers can have varying experiences of disordered gaming behaviours due to coping mechanisms and how they can act as risk or protective factor in the development and/or maintenance of disordered behaviours. A particular area of interest is how this may manifest across different countries. Understanding the interplay of these potential risk and protective factors within different countries will aid identifying and preventing disordered behaviours. Methods: Three cohorts were recruited from Australia, New Zealand, and the United Kingdom. Each cohort was required to complete a battery of psychometric scales exploring problematic behaviours, problematic substance use, co-occurrence, coping styles, and personality. A latent profile analysis was conducted to examine the differences between cohorts and further investigated with additional analyses. Results: The findings suggested that a minority of gamers were affected by gaming disorder, and there appeared an at-risk cohort who utilise gaming as a maladaptive coping strategy. Other accompanying potentially addictive behaviour or substance use may be exacerbated as a result, the manifestation of which can be influenced by cultural elements. Conclusions: When considering gamers from countries which hold similar views, it is important to be cognisant of the variations found in the manifestations of disordered gaming and accompanying potentially addictive behaviours. This will allow for a more precise identification of at-risk behaviours, which will result in more favourable treatment outcomes for those who are considered at-risk or high-risk in iduals.

Abstract: Right frontal function, as indicated by the N200 component of the event-related potential during target detection, has previously been associated with excitement (excitement, impulsivity, hostility, uncooperativeness) in men with a long-term diagnosis of schizophrenia. The current study investigated excitement in relation to N200 in men who had recently experienced their first episode of psychosis. Twenty men who had recently suffered their first psychotic episode underwent a clinical interview and auditory oddball task. Multiple linear regression analysis showed that 58% of the variance in the excitement symptom cluster was explained by a positive association with frontal midline N200 litude and an inverse association with right frontal N200 litude. The latter was not apparent in the initial correlation, suggesting suppression by the midline activity. These associations were not explained by drug use, medication or negative symptoms. However, the correlation between excitement and midline N200 was stronger in drug users, and that between right frontal N200 and excitement was stronger in nonusers. Findings support the independent contributions to excitement of mechanisms reflected in midline and right frontal N200 litude respectively during the early stages of psychosis.

Abstract: Clinical depression is one of the most common psychiatric disorders in adults, yet non-clinical depression in the community may go unnoticed, despite high prevalence rates and significant psychosocial impairment. The aim of the current study was to classify 1,226 in iduals from a community s le on the basis of depression scores (using the Depression Anxiety Stress Scales, DASS) and to determine whether depression in a non-clinical s le differed significantly from healthy controls on a profile of multimodal measures. The data analyzed in this study included personality, emotional intelligence, cognition and psychophysiology. It was predicted that non-clinically depressed participants would differ from healthy controls on measures of personality (increased neuroticism decreased extraversion), emotional intelligence (decreased), cognition (impairments in executive dysfunction and memory impairment), psychophysiology (increased resting-state, right-frontal activation diminished skin conductance) after controlling for gender, age, handedness and years of education. Findings provide support for the majority of hypotheses, though no evidence was found for memory impairment or frontal hemispheric asymmetry. Longitudinal studies are needed to determine the extent to which of these findings will have utility for the prediction of depression onset and treatment response/non-response.

Abstract: The neurobiology of clinical characteristics -in particular depression, insight and negative symptoms- in recent-onset psychosis (ROP) was studied using event-related potentials (ERPs). Twenty right-handed ROP men and 20 controls completed an auditory-oddball task. ROP men had minimum exposure to antipsychotic medication. N100, N200 and P300 were studied to ascertain the effects of (a) diagnosis (patients versus controls), and (b) clinical characteristics. ROP men had significantly lower anterior N100, enhanced N200 at T3, and lower P300 at Pz than controls. Lower right-anterior N100 and enhanced right-anterior N200 litude explained 47.7% of negative symptoms. Left-central N100 litude explained 30.28% of negative symptoms. Lower left-posterior and higher right-posterior P300 litude explained 65.99% of total symptoms. Lower left-central N100, enhanced left-central N200 and depression explained 78.8% of impairments in insight and judgement. Impaired insight/judgement correlated positively with right-anterior N200 and was identified as the most significant co-efficient for depression. Disturbed selective-attention and executive function indexed by N100 and N200, respectively, are associated with poor insight and negative symptoms. A complex interaction exists between insight and depression. The current results demonstrate a biological basis of insight and depression and a complex interaction between the two, perhaps mediated by executive function, in early psychosis.
