Abstract. I selectively and critically review the state of knowledge about human evolution and the place of humans vis‐à‐vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven. 相似文献

We examined the influence of extrapersonal associations (Olson & Fazio, 2004)—associations that neither form the basis of the attitude nor become activated automatically in response to the object—on the Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) by experimentally creating both attitudes and extrapersonal associations. The results revealed that participants who were given extrapersonal information that was inconsistent with their own attitudes were affected by this information when they later performed an IAT. They exhibited significantly reduced IAT scores compared to participants who were provided attitude-consistent extrapersonal information. This attenuation of the IAT effect occurred despite the fact that participants rated the source of the attitude-inconsistent extrapersonal information as irrational and foolish. On the other hand, the extrapersonal associations did not influence a subliminal priming measure in Experiment 1, nor a personalized version of the IAT (Olson & Fazio, 2004) in Experiment 2. These measures proved sensitive to the attitude, regardless of the congruency of the extrapersonal information. 相似文献

Scientific research on facial attractiveness has focused primarily on elucidating universal factors to which all raters respond consistently. However, recent work has shown that there is also substantial disagreement between raters, highlighting the importance of determining how attractiveness preferences vary among different individuals. We conducted a typical attractiveness ratings study, but took the unusual step of recruiting pairs of subjects who were spouses, siblings, or close friends. The agreement between pairs of affiliated friends, siblings, and spouses was significantly greater than between pairs of strangers drawn from the same race and culture, providing evidence that facial-attractiveness preferences are socially organized. 相似文献

The face recognition task we perform [corrected] most often in everyday experience is the identification of people with whom we are familiar. However, because of logistical challenges, most studies focus on unfamiliar-face recognition, wherein subjects are asked to match or remember images of unfamiliar people's faces. Here we explore the importance of two facial attributes -shape and surface reflectance-in the context of a familiar-face recognition task. In our experiment, subjects were asked to recognise color images of the faces of their friends. The images were manipulated such that only reflectance or only shape information was useful for recognizing any particular face. Subjects were actually better at recognizing their friends' faces from reflectance information than from shape information. This provides evidence that reflectance information is important for face recognition in ecologically relevant contexts. 相似文献

Training, coaching, and consulting with people in leadership roles can be a primary consulting function for clinicians. In
this paper, the authors describe their model of leadership, and what they believe to be the central personality or character
components of leadership necessary for producing extraordinary results. Throughout they will show where and how REBT skills
can make a significant contribution. 相似文献

It has been hypothesized that cognitive mechanisms underlying lateralized complex motor actions associated with tool use in chimpanzees may have set the stage for the evolution of left-hemisphere specialization for language and speech in humans. Here we report evidence that asymmetries in the homologues to Broca's and Wernicke's areas are associated with handedness for tool use in chimpanzees. These results suggest that the neural substrates of tool use may have served as a preadaptation for the evolution of language and speech in modern humans. 相似文献

It is well recognized that performance changes over time. However, the effect of these changes on overall assessments of performance is largely unknown. In a laboratory experiment, we examined the influence of salient Gestalt characteristics of a dynamic performance profile on supervisory ratings. We manipulated performance trend (flat, linear-improving, linear-deteriorating, U-shaped, and inverted U-shaped), performance variation (small, large), and performance mean (negative, zero, positive) within subjects and display format (graphic, tabular) between subjects. Participants received and evaluated information about the weekly performance of different employees over a simulated 26-week period. Results showed strong main effects on performance ratings of both performance mean and performance trend, as well as interactions with display format. Theoretical and practical implications of the results are discussed. 相似文献
