Two studies provided evidence that a decision to report an ambiguous case of child abuse affected subsequent memory of the case information, such that participants falsely recognized details that were not presented in the original information, but that are schematically associated with child abuse. Moreover, post‐decision information that the child had later died from abuse influenced the memory reports of participants who had chosen not to report the case, increasing their reports of false schema‐consistent details. This suggests that false decision‐consistent memories are primarily due to sense‐making, schematic processing rather than the motivation to justify the decision. The present findings points to an important mechanism by which decision information can become distorted in retrospect, and emphasize the difficulties of improving future decision‐making by contemplating past decisions. The results also indicate that decisions may generate false memories in the apparent absence of external suggestion or misleading information. Implications for decision‐making theory, and applied practices are discussed. 相似文献

Here we identify the core properties of genetic evolution with the intention of providing a unified definition of evolving systems that applies unequivocally in the natural and social sciences. Our definition is: evolution sustains organized systems through high fidelity replication of information. This definition can be broken down into five essential components: (1) high fidelity replication of information with 0% < survival rate < 100%; (2) expendable replication technology distinct from the replication information; (3) inert information that provides no kinetic energy to the replication process; (4) demonstrates a quantifiable resistance to entropy; (5) demonstrates intentionality. 相似文献

Employing an event-related potential (ERP)-based concealed information test (CIT), the present study investigated (1) the neurocognitive processes when people received feedbacks regarding their deceptive/truthful responses and (2) whether such feedback-related ERP activities can be used to detect concealed information above and beyond the recognition-related P300. During the CIT, participants were presented with rare, meaningful probes (their own names) embedded within a series of frequent yet meaningless irrelevants (others’ names). Participants were instructed to deny their recognition of the probes. Critically, following participants’ responses, they were provided with feedbacks regarding whether they succeeded or failed in the CIT. Replicating previous ERP-based CITs, we found a larger P300 elicited by probe compared to irrelevant. Regarding feedback-related ERPs, a temporospatial Principle Component Analyses found two ERP components that were not only sensitive to feedback manipulations but also can discriminate probe from irrelevant: an earlier, central-distributed positivity that was elicited by “success” feedbacks peaked around 219 ms; and a later, right central-distributed positivity that was also elicited by “success” feedbacks, peaked around 400 ms. Importantly, the feedback ERPs were not correlated with P300 that was elicited by probe/irrelevant, suggesting that these two ERPs reflect independent processes underlying memory concealment. These findings illustrate the feasibility and promise of using feedback-related ERPs to detect concealed memory and thus deception. 相似文献

This paper presents the results of an exploratory, mixed-method study on imams in Flanders. The research question was mainly who are they?, in an attempt to draw the first picture of their socio-demographic background, ethnicity, functions, and expectations with respect to their position in Flanders, or in Belgium more broadly speaking. The first three sections give context information about Muslims, Islam, and mosques in Belgium and Flanders. In the next sections, the research design and the results are presented. This presentation focuses on four issues: imams as immigrants; their tasks and workload; their job situation and attitude towards official recognition and payment; and finally their ambiguous attitudes towards government initiatives. We give also some reflections in dialogue with research on imams in other Western European countries. The conclusion discusses the challenges for imams and the government to become real partners within the further integration process of the Muslim community in Flanders and Belgium. 相似文献

The rubber hand illusion is a perceptual illusion in which a model hand is experienced as part of one’s own body. In the present study we directly compared the classical illusion, based on visuotactile stimulation, with a rubber hand illusion based on active and passive movements. We examined the question of which combinations of sensory and motor cues are the most potent in inducing the illusion by subjective ratings and an objective measure (proprioceptive drift). In particular, we were interested in whether the combination of afferent and efferent signals in active movements results in the same illusion as in the purely passive modes. Our results show that the illusion is equally strong in all three cases. This demonstrates that different combinations of sensory input can lead to a very similar phenomenological experience and indicates that the illusion can be induced by any combination of multisensory information. 相似文献

Embodiment, as measured through the rubber-hand illusion (RHI), depends on the similarity between object to be embodied and part of the body it replaces. We compared a fake hand similar to a real hand, and one matched in size but made of wires (mechanical). Left and right versions were tested to investigate whether the effect of appearance was stronger in the left hand. We found that the mechanical hand induced embodiment, though to a reduced degree relative to the realistic hand (N = 120). Left and right versions of the mechanical hand did not differ in strength of the illusion. However, with the left realistic hand there was a stronger relationship between drift (an objective measure of the illusion) and agreement on the questionnaire (subjective experience). With the mechanical hand, objective and subjective measures were unrelated. We discuss the results in relation to factors that influence the RHI and hemispheric differences. 相似文献

Being socially integrated is regarded as a protective factor enabling people to cope with adversity. The stress-buffering effect reflects an interaction between stress and a social coping resource factor on subsequent outcomes. This study, based on 2943 police officers, examines mental health outcomes among officers who responded to the 9/11 terrorist attack on the World Trade Center. The Wave 1 data collection took place between September 2003 and November 2004 with a follow-up study (Wave 2) conducted from November 2006 through December 2007. A moderated mediation model was specified that uses event exposure as a distal predictor, earlier stress response as a mediator, and later stress response as an outcome, and social integration as a moderator of this relationship. The mediation hypothesis was confirmed, and moderation occurred at two stages. First, there was a multiplicative relationship between exposure levels and social integration: The higher the exposure level, the more stress responses occur, but this effect was buffered by a high level of social integration. Second, Wave 1 stress interacted with social integration on Wave 2 stress: The more the police officers were socially integrated, the lower the Wave 2 stress, which happened in a synergistic manner. The findings contribute to the understanding of mediating and moderating mechanisms that result in health outcomes such as posttraumatic stress disorder or resilience. 相似文献

同一性风格:青少年自我同一性研究的新视角 总被引:4,自引:0,他引:4
近年来,自我同一性问题的研究由关注同一性状态转向关注同一性风格。同一性风格是指个体在建立与维持同一性时表现出的社会认知策略方面的偏好,包括信息风格、规范风格和扩散/逃避风格。研究者围绕同一性风格与社会认知加工策略、人格、家庭环境、心理健康、学业表现等方面关系展开了丰富的研究。未来的研究方法和被试样本应该更加多样化,跨文化比较研究及干预性研究也有待进一步开展。 相似文献
