Perceived health contributes to the attractiveness of facial symmetry, averageness, and sexual dimorphism

Symmetry, averageness, and sexual dimorphism (femininity in female faces, masculinity in male faces) are attractive in faces. Many have suggested that preferences for these traits may be adaptations for identifying healthy mates. If they are, then the traits should be honest indicators of health and their attractiveness should result from their healthy appearance. Much research has focused on whether these traits honestly signal health. Here we focused on whether the appeal of these traits results from their healthy appearance. Specifically, we tested whether the attractiveness of symmetry, averageness, and sexual dimorphism is reduced or eliminated when perceived health is controlled, in two large samples of Western faces and a large sample of Japanese faces. The appeal of symmetric faces was largely due to their healthy appearance, with most associations between symmetry and attractiveness eliminated when perceived health was controlled. A healthy appearance also contributed to the appeal of averageness and femininity in female faces and masculinity in male faces, although it did not fully explain their appeal. These results show that perceptions of attractiveness are sensitive to a healthy appearance, and are consistent with the hypothesis that preferences may be adaptations for mate choice.     

Dysfunctional attitudes and episodes of major depression: Predictive validity and temporal stability in never-depressed, depressed, and recovered women

In a large, community-based sample of women (N = 750), the authors examined the nature of associations between dysfunctional attitudes and depression. Dysfunctional attitudes were evaluated both as a vulnerability factor for depression and as a consequence of depression. A link was found between past depression and baseline elevations in dysfunctional attitudes that was independent of current subsyndromal symptoms, but intensification of dysfunctional attitudes following prospectively evaluated episodes of depression (depressive "scarring") was not observed. Although baseline dysfunctional attitudes predicted an episode of major depression over 3 years of prospective study, this prediction, considered alone or in interaction with negative life events, was redundant with that offered by history of past depression. Further, no significant prediction was evident for the Dysfunctional Attitude Scale (A. N. Weissman & A. T. Beck, 1978) when the formerly depressed and never-depressed cohorts were considered separately. Implications for cognitive theories are discussed.     

German lexical personality factors: relations with the HEXACO model

We correlated the scales of the HEXACO Personality Inventory (HEXACO‐PI) with adjective scale markers of factors previously obtained in indigenous lexical studies of personality structure in the German language. Self‐ratings obtained from a sample of 323 German participants showed a pattern of strong convergent and weak discriminant correlations, supporting the content‐based interpretation of the German lexical factors in terms of the HEXACO dimensions. Notably, convergent correlations were strong for both the broader and the narrower variants of the Honesty‐Humility factor as observed in German lexical studies. Also, convergent correlations for HEXACO Openness to Experience were, as expected, stronger for German adjectives describing a creative and intellectual orientation than for German adjectives describing intellectual ability.

Does spreading activation summate?

Summary Network models of semantic memory assume implicitly or explicitly that the degree of activation of a node is a monotonic function of the total amount of excitation reaching that node from all sources. For example, the activation level of the node representing apple should be greater if it is receiving excitation due to the activation of the nodes for fruit and pear than if only one of these neighboring nodes is activated. This notion was tested by presenting semantic primes 80 ms or 320 ms before a letter string (e.g., apple or ipple) requiring a lexical decision. The prime stimuli consisted of a pair of simultaneous items that were identical in the single prime condition (e.g., fruit/fruit or pear/pear) or different in the double prime condition (e.g., fruit/pear or pear/fruit), and were either related (target = apple) or unrelated (target = copper) to the target, or neutral. As predicted by the summation of semantic activation assumption of network models there was a larger priming effect (in the 320 ms SOA condition) following the simultaneous activation of two related nodes than following the activation of only one node.This research was supported by grants to the first author from the Natural Sciences and Engineering Research Council of Canada.     

The development of memory for own- and other-race faces

This study demonstrates that experience and development interact to influence the "cross-race effect." In a multination study (n=245), Caucasian children and adults of European ancestry living in the United States, Norway, or South Africa, as well as biracial (Caucasian-African American) children and adults living in the United States, were tested for recognition of Asian, African, and Caucasian faces. Regardless of national or biracial background, 8- to 10-year-olds, 12- to 14-year-olds, and adults recognized own-race faces more accurately than other-race faces, and did so to a similar extent, whereas 5- to 7-year-olds recognized all face types equally well. This same developmental pattern emerged for biracial children and adults. Thus, early meaningful exposure did not substantially alter the developmental trajectory. During young childhood, developmental influences on face processing operate on a system sufficiently plastic to preclude, under certain conditions, the cross-race effect.     

How social connectedness affects guilt and shame: Mediation by hope and differentiation of self

We tested a mediation model of social connectedness and guilt and shame. Social connectedness was hypothesized to be related to greater hope and differentiation of self. Hope and differentiation of self, in turn, were expected to be related to less shame and more prosocial guilt. The results found that hope mediated the relationship between social connectedness and guilt, and differentiation of self mediated the relationship between social connectedness and shame. Alternative explanatory models were explored and taken into consideration in the interpretation of the results.     

The importance of the convex hull for human performance on the traveling salesman problem: a comment on MacGregor and Ormerod (1996)

MacGregor and Ormerod (1996) have presented results purporting to show that human performance on visually presented traveling salesman problems, as indexed by a measure of response uncertainty, is strongly determined by the number of points in the stimulus array falling inside the convex hull, as distinct from the total number of points. It is argued that this conclusion is artifactually determined by their constrained procedure for stimulus construction, and, even if true, would be limited to arrays with fewer than around 50 points.
