Attitudinal ambivalence is generally construed as existing when the same attitude object is evaluated simultaneously as both positive and negative. The present research examined the moderating role of attitudinal ambivalence (as assessed by split‐semantic differential measure) on the relationship between bipolar semantic differential measures of attitude and subsequent behaviour using moderated regression analysis. In Study 1, higher levels of attitudinal ambivalence were shown to result in weaker attitude–behaviour relationships for eating a low‐fat diet (N = 140) and eating 5 portions of fruit and vegetables per day (N = 142). Study 2 (N = 361) replicated this effect when also including a measure of past behaviour for eating a low‐fat diet. Implications for understanding the relationship between attitudes and behaviour are discussed. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

A Defining Presidential Moment: 9/11 and the Rally Effect   总被引:1,自引:0,他引:1  
Public approval ratings of George W. Bush surged after the 11 September 2001 terrorist attacks. This study used a quasi–experimental, within–respondents design to investigate the relative contribution of five factors to this classic rally effect: the stimulus event itself, Bush's speech that evening, media exposure, partisan support, and gender effects. Respondents were pretested on the morning of the attacks; one group was posttested immediately after the speech, another group 41 hours later. Stability of effects was examined through an additional study of Bush's 20 September 2001 speech to a joint session of Congress. The findings indicate that Bush's 11 September speech was the critical factor in this rally effect; none of the other factors contributed significantly.  相似文献

Concepts from the health belief, transtheoretical, and dual process models were used to examine how siblings of individuals diagnosed with colorectal cancer (CRC) before age 56 made decisions about CRC screening. Siblings (N = 504) were assessed for CRC screening practices and intentions, pros, cons, processes-of-change, perceived risk of CRC, perceived severity of CRC, preventability of CRC, cancer-related distress, and sibling relationship closeness. Physician and family recommendation and knowledge were also assessed. Fifty-seven percent of participants (n = 287) were compliant with CRC screening. Logistic regression indicated that perceived pros and cons, perceived risk, commitment to screening, health care avoidance, and sibling closeness were associated with screening compliance. Physician and family recommendation were also strong correlates. A similar set of factors was associated with stage of adoption of CRC screening.  相似文献

The science-and-religion dialogue has so often assumed that the key issues for discussion are those that have arisen within the Western Christian religious and intellectual tradition that little interest has been devoted to the possible insights that the presence of non-Christian voices in the dialogue might bring. In the following I explore the benefits of a truly multireligious dialogue on science and religion and offer a model for integrating various religious perspectives into the science-and-religion dialogue. Of course, taking the multifaith perspectives of the religions seriously also means making a dialogue between religions a component of the science-and-religion dialogue, and I discuss how such a dialogue might unfold along with key ideas that might emerge in ever more interesting ways once the dialogue begins.  相似文献

I respond herein to reviews of my recent book by Ann Pederson and Stuart Kurtz. With respect to Pederson's concerns, a constructive theology formulated from the ideas of communication theory need not necessarily neglect pressing historical issues of the poor and powerless. The potential for such relevance remains strong. This is true as well for the application of the system to particular myths and rituals. Also, while I speak positively of computers as instruments of disclosure and the theories upon with they are based as resources for theological construction, this should not be construed as an endorsement of just any application of information technology in a world that tends to distort all good things. With respect to Kurtz's concerns, while thermodynamics plays a role in discussions of the primordial chaos, notions from communication theory are far more central. Also, the use of the language of the theory for theology does not necessarily require theological relevance for all of Claude Shannon's technical conclusions. My uses of infinity are taken from traditional theology and analytic geometry rather than from pure mathematics, although fruitful development along those lines is entirely possible. Pederson and Kurtz are generous with both their praise and concerns. The praise will encourage me to further this project along lines provided by the concerns.  相似文献

Adults recalled the order of the letters in one of two four-letter segments following a distractor task. They knew in advance the identity of the letters in each segment. A letter was made distinctive by replacing it with a red dash. This unusual form of distinctiveness generally had negative effects on recall of both the segment containing the missing letter and the absent letter within the segment. Encoding and output processes were manipulated by varying precue information and recall order instructions, respectively. Informing participants in advance whether or not a trial would contain a distinctive (i.e., missing) letter depressed recall. Constraining output order eliminated the disadvantage for the absent letter. The results are discussed in terms of encoding and output order processes in short-term recall of order information.  相似文献

Consistent with calls for a dynamical social psychology (Jacoby et al., 1987; Nowak, Lewenstein, & Vallacher, 1994), attitude formation was studied using a recently developed, computer‐based simulation technique termed Higher Order Cognitive Tracing (see Jacoby et al., 1994). Participants’ attitudes toward 12 different products in 3 product categories were investigated as a function of incremental information input. As opposed to traditional memory‐based models of attitude formation, the study explored online processing models. Results indicate that the impact of information tends to decrease the later in the sequence that information is accessed. In addition, new information that is affectively inconsistent with prior information tends to have a greater impact on attitudes than information that is affectively redundant. This effect is more pronounced earlier rather than later in the sequence of information acquisition. Implications and suggestions for future research are discussed.  相似文献

The behavioral and public health sciences both have a long and rich history supporting basic, translational, and applied research aimed at improving human lives and reducing human suffering. Through the complementary expertise of these disciplines, investigators have contributed to significant, worldwide improvements in mental and physical health. Further gains can be achieved through collaborative research among scientists in these 2 fields. Unfortunately, there are a number of barriers to such collaboration originating in different intellectual traditions, research methods, and the structure and values of academia. We identify these barriers and potential strategies for overcoming them. Several areas for future collaborative research appear promising, especially comorbid mental and physical disorders, adherence to interventions, stigma, and emotional processes. Theory-guided preventive interventions may represent especially fertile areas of collaborative effort.  相似文献

This study investigated the interrelationships among temperament, social self-efficacy, social competence, and life satisfaction in a sample of 160 early adolescents. A model was proposed based on previous research by Argyle and Lu (1990, Personality and Individual Differences 11, pp. 1255–1261) in which social competence mediates the relationship between temperament (i.e. extraversion and neuroticism) and life satisfaction. However, this study extended the work of Argyle and Lu by including an objective measure of social competence, in addition to a measure of social self-efficacy, to test as a potential mediator between temperament and life satisfaction. Results indicated that social self-efficacy mediated the relationship between extraversion and life satisfaction, but not between neuroticism and life satisfaction. Teacher-rated social competence did not mediate the effects of temperament on life satisfaction. The importance of integrating theories of trait psychology and cognitive psychology in adolescent life satisfaction research is discussed.  相似文献
