We examine the ethical, social, and regulatory barriers that may hinder research on therapeutic potential of certain controversial controlled substances like marijuana, heroin, or ketamine. Hazards for individuals and society and potential adverse effects on communities may be good reasons for limiting access and justify careful monitoring of these substances. Overly strict regulations, fear of legal consequences, stigma associated with abuse and populations using illicit drugs, and lack of funding may, however, limit research on their considerable therapeutic potential. We review the surprisingly sparse literature and address the particular ethical concerns pertinent to research with illicit and addictive substances, such as undue inducement, informed consent, therapeutic misconception, and risk to participants, researchers, and institutions. We consider the perspectives of key research stakeholders and explore whether they may be infected with bias. We conclude by proposing an empirical research agenda to provide an evidentiary basis for ethical reasoning. 相似文献

We examined links between sharing, respect for moral others, and sympathy in an ethnically diverse sample of 7‐ and 15‐year‐olds (N = 146). Sharing was assessed through children's allocation of resources in the dictator game. Children reported their respect towards hypothetical characters performing moral acts. Sympathy was evaluated via caregiver and child reports. Respect and caregiver‐reported sympathy interacted in predicting sharing: Higher levels of respect were associated with higher levels of sharing for children with low, but not medium or high, levels of sympathy. The motivational components of other‐oriented respect may compensate for low levels of sympathetic concern in the promotion of sharing. 相似文献

Eight studies (N=2,973) tested the theory that gratitude is related to fewer depressive symptoms through positive reframing and positive emotion. Study 1 found a direct path between gratitude and depressive symptoms. Studies 2–5 demonstrated that positive reframing mediated the relationship between gratitude and depressive symptoms. Studies 6–7 showed that positive emotion mediated the relationship between gratitude and depressive symptoms. Study 8 found that positive reframing and positive emotion simultaneously mediated the relationship between gratitude and depressive symptoms. In sum, these eight studies demonstrate that gratitude is related to fewer depressive symptoms, with positive reframing and positive emotion serving as mechanisms that account for this relationship. 相似文献

We investigated the causal relation between emotional awareness (EA) and suspiciousness, and whether this relation is moderated by gender. After inducing an unpleasant mood, we manipulated EA by having participants read one of two versions of a story (the high EA condition provided cues to what the participant was feeling and why, whereas the low EA condition did not). Following the manipulation, one sample of participants completed a measure of suspiciousness, and a second, independent sample of participants described their emotional state. Emotional Awareness Condition×Gender effects were obtained for suspiciousness and EA. Men in the low EA condition reported significantly higher levels of suspiciousness and lower levels of EA than men in the high EA condition. Women in both conditions reported equally high levels of EA, which were greater than those of men in both conditions, and the manipulation did not affect their levels of suspiciousness. 相似文献

Retributive justice theory has suggested two processes by which punishment is psychologically satisfying to victims of injustice: leveling the power imbalance caused by the transgression and revalidating social consensus over the importance of the rules, norms, and values violated by the offense. The current investigation proposes a third symbolic function that has not yet been identified as a psychological consequence of punishment: confirmation of the victim's membership status in the group (i.e., intragroup standing or respect). Three studies identified perceptions of intragroup membership status as following from third-party punishment, partly explaining the effect of punishment on a victim's group identification. Study 1 showed that, following the experience of an injustice, punishment prevented perceived membership status threats from resulting in victim disidentification. Study 2 showed that third-party desires to punish increased subsequent identification by symbolically communicating the ingroup's regard for the victim, even when the offender did not actually suffer the effects of third-party sanctions. Finally, Study 3 showed that punishment only implied membership status when the act of punishment was instigated by an ingroup authority and was thus identity-relevant. Taken together, these studies offer the first examination of membership status as a relevant concern underlying retributive justice. 相似文献

An inexpensive circuit is described for the control of light intensity. The control is obtained by a method that produces no color changes and may be programmed by any system that can express itself in four-digit binary numbers. 相似文献
