The experience of agency refers to the feeling that we control our own actions, and through them the outside world. In many contexts, sense of agency has strong implications for moral responsibility. For example, a sense of agency may allow people to choose between right and wrong actions, either immediately, or on subsequent occasions through learning about the moral consequences of their actions. In this study we investigate the relation between the experience of operant action, and responsibility for action outcomes using the intentional binding effect (Haggard, Clark, & Kalogeras, 2002) as an implicit, quantitative measure related to sense of agency. We studied the time at which people perceived simple manual actions and their effects, when these actions were embedded in scenarios where their actions had unpredictable consequences that could be either moral or merely economic. We found an enhanced binding of effects back towards the actions that caused them, implying an enhanced sense of agency, in moral compared to non-moral contexts. We also found stronger binding for effects with severely negative, compared to moderately negative, values. A tight temporal association between action and effect may be a low-level phenomenal marker of the sense of responsibility.  相似文献

When feedback follows a sequence of decisions, relationships between actions and outcomes can be difficult to learn. We used event-related potentials (ERPs) to understand how people overcome this temporal credit assignment problem. Participants performed a sequential decision task that required two decisions on each trial. The first decision led to an intermediate state that was predictive of the trial outcome, and the second decision was followed by positive or negative trial feedback. The feedback-related negativity (fERN), a component thought to reflect reward prediction error, followed negative feedback and negative intermediate states. This suggests that participants evaluated intermediate states in terms of expected future reward, and that these evaluations supported learning of earlier actions within sequences. We examine the predictions of several temporal-difference models to determine whether the behavioral and ERP results reflected a reinforcement-learning process.  相似文献

Multiple-cue probability learning (MCPL) involves learning to predict a criterion when outcome feedback is provided for multiple cues. A great deal of research suggests that working memory capacity (WMC) is involved in a wide range of tasks that draw on higher level cognitive processes. In three experiments, we examined the role of WMC in MCPL by introducing measures of working memory capacity, as well as other task manipulations. While individual differences in WMC positively predicted performance in some kinds of multiple-cue tasks, performance on other tasks was entirely unrelated to these differences. Performance on tasks that contained negative cues was correlated with working memory capacity, as well as measures of explicit knowledge obtained in the learning process. When the relevant cues predicted positively, however, WMC became irrelevant. The results are discussed in terms of controlled and automatic processes in learning and judgement.  相似文献

Background and Objectives: Simultaneous exposure to time, cognitive, and emotional demands is a feature of the work environment for healthcare workers, yet effects of these common stressors in combination are not well established. Design: Survey data were collected from 125 hospital employees (Sample 1, Study 1), 93 ambulance service employees (Sample 2, Study 1), and 380 aged care/disability workers (Study 2). Methods: Hierarchical multiple regressions were conducted. Results: In Sample 1, high cognitive demand exacerbated high emotional demand on psychological strain and job burnout, whereas the negative effect of high emotional demand was not present at low cognitive demand. In Sample 2, a similar pattern between emotional demand and time demand on stress-remedial intentions was observed. In Study 2, emotional demand?×?time demand and time demand?×?cognitive demand interactions again revealed that high levels of two demands were stress-exacerbating and low levels of one demand neutralized the other. A three-way interaction on job satisfaction showed the negative impact of emotional demand was exacerbated when both time and cognitive demands were high, creating a “triple disadvantage” of job demands. Conclusions: The results demonstrate that reducing some job demands helps attenuate the stressful effects of other job demands on different employee outcomes.  相似文献

In-depth interviews were conducted to examine gender-related patterns of adaptation and maladaptation, and the relationship between adaptation and relationships (parents, friends, and romantic partners) for 34 emerging adult immigrants from the Former Soviet Union in Israel. Qualitative analysis highlighted gender-related needs, difficulties, and challenges following the immigration experience. Women’s adaptation was connected to mutually supportive and empathic relationships with parents, friends, and romantic partners. Maladaption for women was connected to overly close, nonmutual, and enmeshed relationships with parents, which led to feelings of guilt or to distant relationships that lacked support and intimacy. Adaptation for men was connected to inner strengths that enabled achievement and success in acculturative tasks, which led to feelings of mastery, competence, and self-definition combined with respect and valuing the relationship they have with their family. In contrast, maladaption among men was not connected to relationships but to a lack of inner strengths needed to succeed in developmental and immigration-related tasks. Despite the gender-related distinction found among less adaptive individuals, adaptive young immigrants, women and men alike, were more characterized by an ability to balance between needs of self and needs of others in their family relationships. As such, narratives of adaptive emerging adult immigrants emphasized gender similarities, whereas those of less adaptive immigrants emphasized gender differences.  相似文献

The call of the Second Vatican Council for the renewal of moral theology has received very divergent responses. This article identifies and compares three such proposals. The underlying presupposition for this analysis is that each proposal begins with a divergent understanding of where the tradition went awry. Hence, the proposed cures ended up irreconcilable. This article seeks to describe ‘as precisely as possible the nature of the confusion and its sources, showing where attention must be directed if a solution is to be discovered.’ 1 1 The anonymous referee of the Heythrop Journal.

The ability of neurons to modify their synaptic strength in an activity-dependent manner has a crucial role in learning and memory processes. It has been proposed that homeostatic forms of plasticity might provide the global regulation necessary to maintain synaptic strength and plasticity within a functional dynamic range. Similarly, it is considered that the capacity of synapses to express plastic changes is itself subject to variation dependent on previous experience. In particular, training in several behavioral tasks modifies the possibility to induce long-term potentiation (LTP). Our previous studies in the insular cortex (IC) have shown that induction of LTP in the basolateral amygdaloid nucleus (Bla)-IC projection previous to conditioned taste aversion (CTA) training enhances the retention of this task. The aim of the present study was to analyze whether CTA training modifies the ability to induce subsequent LTP in the Bla-IC projection in vivo. Thus, CTA trained rats received high frequency stimulation in the Bla-IC projection in order to induce LTP 48, 72, 96 and 120 h after the aversion test. Our results show that CTA training prevents the subsequent induction of LTP in the Bla-IC projection, for at least 120 h after CTA training. We also showed that pharmacological inhibition of CTA consolidation with anisomycin (1 μl/side; 100 μg/μl) prevents the CTA effect on IC-LTP. These findings reveal that CTA training produces a persistent change in the ability to induce subsequent LTP in the Bla-IC projection in a protein-synthesis dependent manner, suggesting that changes in the ability to induce subsequent synaptic plasticity contribute to the formation and persistence of aversive memories.  相似文献

Gestational surrogacy, in which the surrogate mother is not biologically related to the child she is carrying, is the most common type of surrogacy today. Although technologically well-developed and legal in many countries, it is stigmatized socially because it provokes and even contradicts basic traditional concepts of family, motherhood, and gender roles. The present study examines the types and expressions of the surrogacy stigma in Russia, applying a dual-pathway stigma model to a qualitative content analysis of 15,602 posts on a Russian-language online forum for surrogate mothers. Our findings reveal that the women’s choice to become surrogate mothers initiated a social process in which these women experienced four types of stigma: Bad mothers, bad wives, pathetic losers, and greedy women. Surrogate mothers described the experience and internalization of stigma as threatening their social roles in the traditional family and financial realm alike. Our study places surrogacy stigma in the context of the post-Soviet financial and social climate as experienced and expressed by participants. Furthermore, understandings of the essence of perceived surrogacy stigma may help professionals develop a more nuanced and accurate approach for psychological and social care and may lead to increased accuracy in media, law, and political representation of members of this vulnerable group.

Previous research suggests that exposure to accent variability can affect toddlers’ familiar word recognition and word comprehension. The current preregistered study addressed the gap in knowledge on early language development in infants exposed to two dialects from birth and assessed the role of dialect similarity in infants’ word recognition and comprehension. A 12-month-old Norwegian-learning infants, exposed to native Norwegian parents speaking the same or two Norwegian dialects, took part in two eye-tracking tasks, assessing familiar word form recognition and word comprehension. Their parents’ speech was assessed for similarity by native Norwegian speakers. First, in contrast to previous research, our results revealed no listening preference for words over nonwords in both monodialectal and bidialectal infants, suggesting potential language-specific differences in the onset of word recognition. Second, the results showed evidence for word comprehension in monodialectal infants, but not in bidialectal infants, suggesting that exposure to dialectal variability impacts early word acquisition. Third, perceptual similarity between parental dialects tendentially facilitated bidialectal infants’ word recognition and comprehension. Forth, the results revealed a strong correlation between the raters and parents’ assessment of similarity between dialects, indicating that parental estimations can be reliably used to assess infants’ speech variability at home. Finally, our results revealed a strong relationship between word recognition and comprehension in monodialectal infants and the absence of such a relationship in bidialectal infants, suggesting that either these two skills do not necessarily align in infants exposed to more variable input, or that the alignment might occur at a later stage.  相似文献
