Effects of persuasive messages, responsibility denial (RD), and attitude-accessing on blood-giving attitudes, intentions, moral obligations, and behavior were examined. In Study 1, participants (n= 84) who heard a message emphasizing moral reasons for donating indicated a more favorable postmessage attitude and stronger moral obligation to donate than participants exposed to a message aimed at reducing fear, a combined moral and fear- reduction message, or no message. Combined message participants showed greatest intent to donate, yet only 14% of all participants attended a campus drive. In Study 2, low (n= 52) and high (n= 60) RD individuals heard the message arguments and were asked to access their attitudes. Low compared to high RD individuals stated a stronger sense of moral obligation, particularly when they accessed their thoughts relevant to blood donating, and behavioral intention, especially in the combined message condition. Few participants attended a blood drive (12.5%), yet most were low RD individuals from the nonaccessed attitude condition (83%). Results suggest that few individuals will engage in the altruistic act of blood donating, despite the experimental use of persuasive messages and accessing issue-relevant attitudes.  相似文献

This article addresses the relationship between religious affiliation and a very specific form of firearms ownership, that is, handgun ownership. Literature is reviewed relative to explanations of gun ownership. A test of the hypothesized relationship between religious affiliation and handgun ownership demonstrated a statistically significant ( p < 0.03) association. Protestants were found to have a disproportionately high level of handgun ownership compared to other religious groups. Speculation for this finding is reviewed relative to other recent research on this topic.  相似文献

The concept of developmental amnesia is proposed to describe the impairment of normal memories during a person's school age life. One hundred psychotherapy patients were interviewed and the age of earliest memories ranged from 1–12 years, with a mode of 5 years. Memory was continuous for 53% of patients by 1st grade, while 18% reported life memory was still episodic at age 18 or later. Parental alcohol problems were associated with delay of continuous memories.  相似文献

Since valuing is a process grounded in the organizational tendency of human behavior, the characteristics of a highly valued object should reflect the experience of the individual who selects it. This research compared the favorite songs of fourteen individuals diagnosed with schizophrenia to their inner experience as assessed in a standard interview. Many relationships were revealed between the two, often pertaining to important issues identified in theories of schizophrenia. Results may have therapeutic applications and shed light on processes through which psychological difficulties persist.  相似文献

This article comments on a recent article by Heatherton, Herman, and Polivy (1991) in which they suggest that ego threats are a prerequisite to affectively induced disinhibition of food intake in restrained eaters and current dieters. In contrast, the present review suggests that mood induction procedures that involve no apparent threat (e.g., viewing a frightening film) can also prompt disinhibition in restrained eaters. Thus, any mood induction procedure that does not directly physically threaten the S may disinhibit restrained eaters. It is concluded that recommendations to focus future research on ego threats are premature and may serve to obscure the mechanisms by which changes in affective state influence food intake in dieters.  相似文献

Defensive reactions to aid in the context of a close relationship were studied. Young adult siblings reported on their self-esteem, the quality of the sibling relationship, relevant demographic variables, and a variety of components of defensiveness to aid. Consistent with theory, the components of defensiveness were interrelated. A large percentage (52%) of the variance in defensiveness was accounted for by conflict between siblings, dominance relative to one's sibling, low global self-esteem, high self-esteem when comparing oneself with one's sibling, and low levels of feelings of entitlement. Siblings were least defensive in reaction to aid from older and female siblings. Corroboration from a subset of benefactor siblings was obtained. The results are discussed in relation to recent thinking about the nature of receiving support in close relationships and recipients' reactions to aid.  相似文献
