Neuropsychological correlates of impaired emotion recognition following traumatic brain injury

Previous research has shown that individuals with traumatic brain injury (TBI) are significantly impaired on emotion recognition tasks. In this study, the relationship between neuropsychological functioning and emotion recognition was examined in 11 individuals with moderate to severe TBI and a control group of 13 individuals matched for age,sex, and education. Emotion recognition stimuli were from Ekman and Friesen's pictures of facial affect. The group with TBI showed neuropsychological deficits consistent with those commonly found following moderate to severe TBI. The group with TBI also identified significantly fewer emotion recognition stimuli than the control group.The number of correctly identified emotion recognition stimuli was significantly correlated with measures of verbal cognitive processing in the group with TBI. These findings suggest that the role of left hemisphere brain mechanisms in the recognition of facial (nonverbal)emotion may be more important than previously recognized.     

The Most Agreeable of All Vices: Nietzsche as Virtue Epistemologist

It has been argued with some justice by commentators from Walter Kaufmann to Thomas Hurka that Nietzsche's positive ethical position is best understood as a variety of virtue theory – in particular, as a brand of perfectionism. For Nietzsche, value flows from character. Less attention has been paid, however, to the details of the virtues he identifies for himself and his type. This neglect, along with Nietzsche's frequent irony and non-standard usage, has obscured the fact that almost all the virtues he praises are intellectual rather than moral. The vices he most despises include dogmatism, intellectual partisanship, faith, boredom, the desire for certainty and pity. The virtues he most appreciates include curiosity, honesty, scepticism, creativity, the historical sense, intellectual courage and intellectual fastidiousness. These tables of values place Nietzsche squarely among so-called responsibilist virtue epistemologists, such as Lorraine Code and Linda Zagzebski, who emphasize that knowledge is infused with desire and affect. I argue that curiosity construed as the specification of the will to power in the domain of epistemology is the cardinal Nietzschean virtue, and that the others – especially intellectual courage and honesty – are presupposed by curiosity. Thus, Nietzsche turns out to accept his own peculiar brand of the thesis of the unity of virtue.     

Prevalence of Anxiety and Depression in Australian Adolescents: Comparisons with Worldwide Data

Data from two Australian studies were combined so that the prevalence of anxiety and depression in a large, normative sample of Australian adolescents could be investigated. The combined sample comprised 1,299 adolescents randomly selected from metropolitan and country schools in Melbourne, a large Australian city. The data were examined in order to ascertain the percentages of adolescents who scored above the clinical cut-off on two self-report instruments-the Revised Children's Manifest Anxiety Scale (C. R. Reynolds & B. 0. Richmond, 1985) and the Reynolds Adolescent Depression Scale (W. M. Reynolds, 1986). The results of these analyses were then compared with previously reported prevalence rates from studies worldwide. This comparison revealed striking differences in the prevalence of anxiety and depression across different countries and cultures. Limitations attributable to different self-report measures and imposed-etic approaches are discussed. Issues pertaining to social and political climate are also raised.     

Hemifacial preferences for the perception of emotion and attractiveness differ with the gender of the one beheld

Though the left cheek appears more emotive, perceptions of attractiveness vary with gender. For the first time, this study assessed the relationship between perceptions of emotion (happiness) and attractiveness in naturalistic photographic portraits. One hundred ninety-two participants (63 male; 129 female) viewed pairs of left and right cheek poses, and made a forced-choice decision indicating which image appeared (a) more emotive and (b) more attractive (order counterbalanced). Half the images were mirror-reversed to control for perceptual biases. Results indicated a striking gender difference: for males, the left cheek appears both more emotive and more attractive; for females, preferences are subject to stronger perceptual influences, with the right cheek bias for emotion and attractiveness reversing to a left cheek bias when images are mirror-reversed. These findings suggest that if you want to show the world your “best side”, men should lead with the left but for women, the right cheek is right.
