Impairments of Theory of Mind (ToM) abilities occur in a wide range of brain disorders. Therefore, reliable and ecologically valid examination of these abilities is a crucial part of any comprehensive neuropsychological assessment. An established and ecologically valid, English-language test identifying deficits in ToM abilities is “The Awareness of Social Inference Test – Social Inference Minimal (TASIT-SIM)”. However, no comparable German-language ToM test currently exists. In this study, we aimed to develop the first German-language adaption of TASIT-SIM in healthy adults. We selected 13 scenes [four scenes per message type (i.e., honesty, simple sarcasm, paradoxical sarcasm) and one practice scene] out of the 30 TASIT-SIM scenes. In collaboration with a film institute, we filmed each scene at three different intensities. These intensity version scenes were then administered to 240 healthy adults, equally distributed in sex and age, ranging from 35 to 92 years. By applying Rasch analysis, we selected intensity versions that showed neither floor nor ceiling effects in the majority of ToM questions in participants whose ToM abilities were in the medium range. In conclusion, we have developed the first German-language adaption of TASIT-SIM, i.e., the “Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM)”. The BASIT-ToM incorporates the strengths of TASIT-SIM, while overcoming its limitations such as inconsistencies in cinematic realization and ceiling effects in healthy participants. Next, the BASIT-ToM needs to be validated in healthy people and clinical populations.  相似文献

Guided by the self-determination theory, this weekly diary study tested a process model in which week-to-week mother-reported interparental conflict and perceived partner responsiveness were associated with maternal autonomy support by means of maternal psychological need satisfaction. During six consecutive weeks, 258 mothers (Mage = 41.71 years) and their 157 adolescents (51.4% females, Mage = 14.92 years) from Turkey provided weekly reports of the study variables via an online survey. Multilevel analyses showed that maternal need satisfaction was predicted by lower levels of interparental conflict and greater levels of perceived partner responsiveness. Maternal need satisfaction, in turn, was positively associated with maternal and adolescent reports of maternal autonomy support. Further, these week-to-week associations were partly moderated by maternal perfectionism. The results underscore the dynamic nature of the intra-family relationships, the important role of particular conditions in which mothers may become more autonomy supportive, and the necessity to consider mother’s personal characteristics while examining these dynamics.  相似文献

The purpose of this study was to evaluate the role of prosocial behaviour against aggression in a school-based universal intervention adapted in two different (non-Western) countries, Colombia and Chile. Using a randomised pretest–post-test design (and controlling for participants' gender and parents' level of education), current results highlighted different effects of a similar programme in both sites. First, the school-based universal programme designed for promoting prosocial behaviours in the peer context obtained a positive cross-national effect on prosocial behaviour rated by three informants (i.e. self, peer and teacher reports). In Colombia, this effect was moderated by the initial level of prosociality of the participants and their level of education. Mediational two-wave model corroborated that the improvement on prosocial behaviours in both countries (moderated in the case of Colombia) predicted significantly lower level of physical aggression. Characteristics of the implementation considering different cultural and historical backgrounds were discussed.  相似文献

People rely on support from others to accomplish mundane and momentous tasks. When asking for assistance, is it beneficial to incentivize a helper by offering a motivated gift (i.e., a gift with the hope of getting support in return)? Six studies (N > 2,500) examine the frequency and potential costs of motivated gifts. In Study 1, a third of Americans indicated that they had given a motivated gift at least once, while nearly two‐thirds believed they had received one. In Studies 2a–d, most participants who imagined receiving a motivated gift before a favor request reported lower willingness to help and anticipated satisfaction from helping than participants who imagined simply being asked for a favor. Finally, Study 3 replicates these findings with actual help provided among friends in a laboratory setting. Findings suggest that motivated gifts are relatively common but may sometimes undermine the assistance that people hope to receive.  相似文献

Previous research indicates that manipulating dimensions of reinforcement during differential reinforcement of alternative behavior (DRA) for situations in which extinction cannot be implemented is a potential approach for treating destructive behavior. Therefore, we replicated and extended previous research by determining (a) the conditions under which DRA without extinction decreased and maintained low levels of destructive behavior and (b) whether intervention effects maintained during reinforcement schedule thinning for the alternative response (i.e., compliance). Results showed that effective treatments were developed in the absence of extinction by manipulating the quality of reinforcement for compliance for 2 participants and by combining manipulations of the magnitude and quality of reinforcement for compliance for the other 2 participants. However, maintaining treatment effects during reinforcement schedule thinning required combining the magnitude and quality of reinforcement for 3 of the 4 participants. We discuss the clinical utility of this approach, review limitations of the study, and suggest directions for future research.  相似文献

The long-term negative consequences of job insecurity on employees’ health and well-being have been demonstrated by several studies, but there is very little evidence on the daily experience of job insecurity and on the factors that may influence it. Therefore, we investigated whether short-term changes occur in the experience of job insecurity and whether these are influenced by daily co-worker conflicts. We carried out a diary study, in which 66 employees answered a questionnaire over the course of five working days. We conducted a multilevel analysis in which we included co-worker conflicts as a predictor, and type of contract, emotional stability, and aggregated job insecurity perceptions as control variables. Our results revealed that job insecurity varies on a daily level, and that 23 per cent of the variance could be explained at a within-person level. Co-worker conflicts were a significant positive predictor for perceived job insecurity in subsequent days after controlling for aggregated job insecurity perceptions at person level. Reversed causation was not found. Practical implications for organisations should focus on the promotion of positive social relations in the work environment in order to mitigate or avoid the negative consequences of social stressors in uncertain times.  相似文献

ABSTRACT

Forgiveness is a universal construct. A forgiveness measure should ensure good and diverse cultural representation and inclusivity in its development, validation and usage. The 15-item Bolton Forgiveness Scale (BFS) assesses dispositional forgiveness. Items came from interviews with 53 Nigerian and British people, existing scales and the research literature. Exploratory factor analysis with a student sample (n = 733) was followed by confirmatory factor analysis with a general sample (n = 2,017). This indicated a robust three-factor structure. Factors were, coming to terms and letting go (CLTG), developing positive feelings (DPF) and giving benefit of the doubt (GBD). Scale Validity was established and a new forgiveness definition emerged as a process that involves developing and strengthening the capacity to give benefit of the doubt that enables the offended come to terms with and let go of hurt with its negative affect thereby giving way gradually to positive feelings towards the transgressor.  相似文献

Protein synthesis-dependent, synapse input-specific late phases of long-term potentiation (LTP) and depression (LTD) may underlie memory formation at the cellular level. Recently, it was described that the induction of LTP can mark a specifically activated synapse by a synaptic tag to capture synapse non-specific plasticity-related proteins (PRPs) and thus maintaining input-specific LTP for prolonged periods. Here we show in rat hippocampal slices in vitro, that the induction of protein synthesis-dependent late-LTD is also characterized by synaptic tagging and that heterosynaptic induction of either LTD or LTP on two sets of independent synaptic inputs S1 and S2 can lead to late-associative interactions: early-LTD in S2 was transformed into a late-LTD, if late-LTP was induced in S1. The synthesis of process-independent PRPs by late-LTP in S1 was sufficient to transform early- into late-LTD in S2 when process-specific synaptic tags were set. We name this new associative property of cellular information processing 'cross-tagging.'  相似文献
