This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge, behavioral skills, or condom use. Results indicated that across the sample of studies, communications taught recipients about facts related to HIV and also induced favorable attitudes and expectancies, greater control perceptions, and stronger intentions to use condoms in the future. Moreover, messages that presented attitudinal information and modeled behavioral skills led to increased condom use. Results are discussed in the context of theories of human behavior and change and in reference to HIV-prevention interventions. 相似文献

The proposed model for consciousness, called a dyadic model, is based upon reexamination of traditional thought structures in the light of modern experimental evidence from a number of scientific fields. It is an evolutionary cosmological model using energy and information as fundamental concepts. It proposes that the antecedent attributes of anthropic consciousness find their roots in the field of zero point quantum potential which gave rise to the Big Bang. In this model consciousness has both a fundamental aspect and an evolutionary aspect in the same sense that quantized energy manifests fundamentally as wave/particles and is observed in more complex form as molecular matter. Physical existence evolved through natural process into ever more complex organizations of matter; so also must anthropic consciousness have evolved from more fundamental antecedent characteristics. The dyadic model proposes a scenario for this evolution that corresponds to the appearance of the universe we seem to inhabit. 相似文献

There are high rates of suicide ideation and/or behavior in severely obese individuals. The potential contributors to suicide ideation in a sample of 334 severely obese bariatric surgery candidates was explored. Lack of college education, a history of suicide ideation and/or behavior, psychological distress, hopelessness, loneliness, history of physical and/or sexual abuse, and lifetime major depression were associated with current suicide ideation. Some of the correlates of suicide ideation in severely obese bariatric surgery‐seeking samples are similar to those found in the general community and this knowledge may serve to improve the psychological assessment and care for this group. 相似文献

A new model for predicting the frequencies of apparent reversals in rotating trapezia, proposed by the authors in 1983, is validated and extended in two studies. Experiment 1 showed that the model retained its predictive efficiency over an increased range of shapes and viewing distances, and with trapezia made of sheet metal and not, as previously, of wire. Experiment 2 was designed to investigate an unexpected effect, in which the specificity of prediction was found to decrease as the corners of the stimulus objects were slightly rounded. 相似文献
