A field study exposed 235 high school students to anti‐smoking advertisements over a five‐month period to test the effectiveness of short‐term cosmetic versus long‐term health fear appeals in preventing or reducing smoking. The study was a longitudinal experiment with two experimental groups and a control group. Smoking behaviour was measured prior to message exposure on television, in magazines and on the internet, and at the end of the study period. The primary results were that average smoking declined for subjects exposed to either type of anti‐smoking fear appeal but not for the control group and short‐term cosmetic fear appeals were more effective for males but long‐term health fear appeals were more effective for females.

School bullying has become a topic of public concern and considerable research in various countries around the world in the last two decades. We summarise characteristics such as types and causes of school bullying, based on findings from various studies. We further review a variety of large-scale, school-based intervention programmes, implemented in different countries and school settings, that have been systematically evaluated. These programmes have varied substantially in their effectiveness in reducing levels of bullying at schools. Reasons for these mixed outcomes are discussed, together with suggestions for improving the effectiveness of future interventions. 相似文献

Because the way mothers play with their children may have significant impacts on children's social, cognitive, and linguistic development, researchers have become interested in potential predictors of maternal play. In the present study, 40 mother–infant dyads were followed from child age 5–20 months. Five‐month habituation rate and 13 and 20 month temperamental difficulty were found to be predictive of maternal play quality at 20 months. The most parsimonious theoretical model was one in which habituation was mediated by temperamental difficulty in predicting mother play. Consistent with prior speculation in the literature, these data support the possibility that mothers adjust some aspects of their play behaviors to fit their children's cognitive and temperamental capabilities.

The interplay between two perspectives that have recently been applied in the attitude area—the social identity approach to attitude‐behaviour relations (Terry & Hogg, 1996 ) and the MODE model (Fazio, 1990a )—was examined in the present research. Two experimental studies were conducted to examine the role of group norms, group identification, attitude accessibility, and mode of behavioural decision‐making in the attitude‐behaviour relationship. In Study 1 (N = 211), the effects of norms and identification on attitude‐behaviour consistency as a function of attitude accessibility and mood were investigated. Study 2 (N = 354) replicated and extended the first experiment by using time pressure to manipulate mode of behavioural decision‐making. As expected, the effects of norm congruency varied as a function of identification and mode of behavioural decision‐making. Under conditions assumed to promote deliberative processing (neutral mood/low time pressure), high identifiers behaved in a manner consistent with the norm. No effects emerged under positive mood and high time pressure conditions. In Study 2, there was evidence that exposure to an attitude‐incongruent norm resulted in attitude change only under low accessibility conditions. The results of these studies highlight the powerful role of group norms in directing individual behaviour and suggest limited support for the MODE model in this context.

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc. 相似文献

Activation of Political Attitudes: A Psychophysiological Examination of the Hot Cognition Hypothesis 总被引:1,自引:0,他引:1

The recording of event-related potentials (ERPs) in the brain has allowed for a better understanding of human sensory and cognitive processing. This technique may also prove useful in studying implicit social attitudes and their effects on information processing. Here, ERPs were used in a study of "hot cognition" in the context of political concepts. Hot cognition, as applied to the political domain, posits that all sociopolitical concepts that have been evaluated in the past are affectively charged, and that this affective charge is automatically activated from long-term memory within milliseconds of presentation of the political stimulus. During an evaluative priming task, ERP recordings showed that affectively incongruent prime/target pairs elicited an enhanced negativity with a peak latency of about 400 milliseconds relative to affectively congruent prime/target pairs. These differences suggest that automatic, implicit evaluations were made in response to strongly positive and negative political stimuli, and that these evaluations affected the subsequent processing of a high-valence adjective. Therefore, it appears that the emotional valence of a political prime is stored along with the concept itself, and that an affective response becomes active upon mere exposure to the political stimulus. 相似文献

The phenotypic and genetic factor structure of performance on five Multidimensional Aptitude Battery (MAB) subtests and one Wechsler Adult Intelligence Scale—Revised (WAIS-R) subtest was explored in 390 adolescent twin pairs (184 monozygotic [MZ]; 206 dizygotic (DZ)). The temporal stability of these measures was derived from a subsample of 49 twin pairs, with test–retest correlations ranging from .67 to .85. A phenotypic factor model, in which performance and verbal factors were correlated, provided a good fit to the data. Genetic modeling was based on the phenotypic factor structure, but also took into account the additive genetic (A), common environmental (C), and unique environmental (E) parameters derived from a fully saturated ACE model. The best fitting model was characterized by a genetic correlated two-factor structure with specific effects, a general common environmental factor, and overlapping unique environmental effects. Results are compared to multivariate genetic models reported in children and adults, with the most notable difference being the growing importance of common genes influencing diverse abilities in adolescence. 相似文献

Much of Western speculative metaphysics has subscribed to what has been called “explanatory rationalism,” which holds that there is a reason for everything that is and for the way everything is. Theodicies, or metaphysical attempts to solve the problem of evil, have relied on a special application of this principle of explanatory rationalism, namely, the principle of plenitude, which holds that the evil in the world is a necessary ingredient in the world's overall perfection or degree of reality. This essay argues that the principle of plenitude is aesthetically motivated, and that only in art and perhaps in revealed religion can the demands of explanatory rationalism be satisfied. 相似文献
