Arousal-related processes associated with heightened heart rate (HR) predict memory enhancement, especially for emotionally arousing stimuli. In addition, phasic HR deceleration reflects "orienting" and sensory receptivity during perception of stimuli. We hypothesized that both tonic elevations in HR as well as phasic HR deceleration during viewing of pictures would be associated with deeper encoding and better subsequent memory for stimuli. Emotional pictures are more memorable and cause greater HR deceleration than neutral pictures. Thus, we predicted that the relations between cardiac activity and memory enhancement would be most pronounced for emotionally-laden compared to neutral pictures. We measured HR in 53 males during viewing of unpleasant, neutral, and pleasant pictures, and tested memory for the pictures two days later. Phasic HR deceleration during viewing of individual pictures was greater for subsequently remembered than forgotten pictures across all three emotion categories. Elevated mean HR across the entire encoding epoch also predicted better memory performance, but only for emotionally arousing pictures. Elevated mean HR and phasic HR deceleration were associated, such that individuals with greater tonic HR also showed greater HR decelerations during picture viewing, but only for emotionally arousing pictures. Results suggest that tonic elevations in HR are associated both with greater orienting and heightened memory for emotionally arousing stimuli. 相似文献
Studies examining trends over time in mainstream magazines observe decreases in women's figure size, and increases in figure exposure and amount of diet/exercise content. Little is known, however, regarding the content of African American magazines. Utilizing methods from classic studies, this investigation examined content in Ebony, a magazine with wide African American readership, from 1969 to 2008. We included the full content of N = 462 issues, with a total of N = 539 cover images of women, of which N = 208 were full-body shots. Analyses indicated a curvilinear relationship between time and figure exposure, with a recent trend toward more full-body shots, similar to mainstream magazines. Contrary to previous studies, however, the majority of figures across time were average size, and a curvilinear relationship between time and diet/exercise content showed peak content in the early 1990s. Results are considered in context of research indicating African American women show less body dissatisfaction than other racial/ethnic groups. 相似文献

The purpose of the present research was to examine the perceptions of women who drink in social contexts through the lens of dehumanization (Haslam 2006). Across three experiments, we manipulated the presence of alcohol by depicting a woman at a bar with a bottle of beer or a bottle of water and measured dehumanization. As hypothesized, women were dehumanized more in the alcohol condition than in the water condition by men (Experiments 1–3) and women (Experiments 2 and 3). Notably, the presence of alcohol compared to water had no impact on dehumanization of men (Experiment 2). Also, as hypothesized, perceived intoxication emerged as a significant mediator of the link between alcohol condition and dehumanization in Experiments 1 and 2, and alcohol quantity predicted greater dehumanization in Experiment 3. Extending the present work to prior work in this area, Experiment 3 also examined the links among alcohol, perceived sexual availability, and dehumanization, revealing that perceived sexual availability mediated the link between alcohol and dehumanization. Implications for theories of dehumanization, alcohol, and social perception as well as practical implications of these findings are discussed.
Abstract. Evolution of the human capacity for beliefs is considered in relation to the emergence in human phylogeny of the ability to formulate propositions, evaluate their worth as bases for action, and make emotional attachments to them. Most of the relevant capabilities had appeared in primate evolution before the emergence of the Hominidae. The combination of capabilities peculiar to evolving hominines was that involved in the development of language, which ontogenetic evidence suggests began as a tool for implementing intentionality in social interaction and whose subsequent elaboration was associated with later reportorial and narrative uses. 相似文献
IQs were correlated with the z score of suicide rate minus z score of homicide rate using nine regions of the world--established market economies, formerly socialized Europe, India, China, other Asian nations, Sub-Saharan Africa, Latin America/Caribbean, Middle East Crescent, and the USA. Correlations were .85 and .83 with crude rates and age-adjusted rates, respectively. The homicide findings are consistent with previous research in individual countries showing that less intelligent persons commit homicide more often. However, the present findings of a positive correlation between IQ and suicide rates are the opposite of what has been found in the more definitive studies within countries. Explanations for the apparent paradox and for the findings more generally were offered. 相似文献
