Previous research has found that physical characteristics in faces that influence perceptions of trustworthiness and dominance have context-contingent effects on leadership perceptions. People whose faces are perceived to be trustworthy are judged to be better leaders in peacetime contexts than wartime contexts. By contrast, people whose faces are perceived to be dominant are judged to be better leaders in wartime contexts than peacetime contexts. Here we tested for judgment-contingent (dominance versus trustworthiness) effects of head tilt on person perception and context-contingent (peacetime versus wartime) effects of head tilt on leadership judgments. Although we found that head tilt influenced trustworthiness and dominance (Study 1), head tilt did not influence leadership judgments (Study 2). Together, these results suggest that the context-contingent effects of physical characteristics on leadership judgments reported in previous work do not necessarily extend to head tilt, even though head tilt influences perceptions of trustworthiness and dominance.

Envy stems from a social comparison with a superior standard. Its 2 distinct forms are directed at changing this situation in different ways, either by becoming as successful as the envied person (in benign envy) or by lowering the envied person’s advantage (in malicious envy). In essence, envy is thus a social phenomenon. Nevertheless, most previous research has focused on its underlying intrapersonal processes, overlooking envy’s interpersonal core. In contrast, we show in 6 studies (N = 1,513) that envy and pride are intertwined in a social-functional relationship. Envy and pride often co-occur (Study 1) and pride displays enhance envious feelings (Studies 2 and 3). Specifically, authentic (success attributed to effort) and hubristic pride (success attributed to talent) modulate envious intentions and behavior toward their benign and malicious form (Study 2 to 6). This effect is mediated via liking, perceived prestige, and perceived dominance (Study 4). In accordance with a social-functional approach, the effects emerge only when authentic and hubristic pride are expressed by the superior person and not when the respective information about the superior person’s feelings is simply available in the environment (Study 5). These effects are present when participants recall envy situations (Study 1), when they imagine being in a competitive situation (Studies 3, 4, and 5), or when envy is elicited in situ (Studies 2 and 6). Our findings show the value of studying envy as a social phenomenon and open up numerous avenues for research on envy at the interpersonal and intergroup level.

Aims:The purpose of this study was to distinguish electroencephalographic possible typical features at left handed children as against to right children, and also to find out possible range aspects which can suggests the central dominance for language.Method:Electroencephalographic (EEG) band was recorded on an EEG device (Pegasus Digital EEG-EMS GmbH - Austria) according to the international standards.Subjects:Sample I: 8 left handed children (av. 9.38 SD 3.53 yrs); Sample II: 18 right handed children (av. 11.06 SD 2.48 yrs).Using the data obtained by Fast Fourier Transform (FFT), we performed comparisons regarding the index, and the average frequency for delta, theta, alpha, and beta bands. The comparisons was performed for each subject, for each band, and pair of electrode between left and right hemisphere, between left and right children for every electrode, and for the two hemispheres.Results:We have found significant differences on EEG features between left and right children regarding both index, and frequency of the main cerebral rhythm, the most meaningful been at alpha, and beta rhythms. For instance the beta frequency was higher on the left recordings, mostly at right children, where seven of the electrode pairs presents significant differences.Conclusions:In contrast with classical, and virtual analysis the Digital EEG, and FFT test is a method that can be useful to study the cerebral dominance. The advantage of this method pleads the fact that firstly it is a noninvasive method, and despite other sophisticated functional techniques remains the most inexpensive.

Detailed three-dimensional nonlinear finite element (FE) analyses and experimental moire studies are performed on a plate containing a moderately deep part-through surface crack to establish limits of HRR-dominance. The plate is subjected to predominantly far-field tensile loading. The material under investigation is ASTM A710 steel, which was constitutively modeled by large deformation J2 flow theory of plasticity. The FE mesh was carefully constructed to resolve both crack front fields (such as J-integral and CTOD) and global fields (such as surface displacements, strains). By comparing the J-integral and CTOD results with an earlier HRR-dominance study using (small strain) deformation theory of plasticity, we found little effect of the different formulations on the crack front fields. The global deformation fields from the numerical simulation are in good agreement with our experimental results. The eventual loss of HRR-dominance is intimately related to the interaction of the global plastic flow fields with those of the crack front.
