Decision reversals often imply improved decisions. Yet, people show a strong resistance against changing their minds. These are well‐established findings, which suggest that changed decisions carry a subjective cost, perhaps by being more strongly regretted. Three studies were conducted to explore participants' regret when making reversible decisions and to test the hypothesis that changing one's mind will increase post‐outcome regret. The first two studies employed the Ultimatum game and the Trust game. The third study used a variant of the Monty Hall problem. All games were conducted by individual participants playing interactively against a computer. The outcomes were designed to capture a common characteristic of real‐life decisions: they varied from rather negative to fairly positive, and for every outcome, it was possible to imagine both more and less profitable outcomes. In all experiments, those who changed their minds reported much stronger post‐outcome regret than those who did not change, even if the final outcomes were equally good (Experiments 2 and 3) or better (Experiment 1).This finding was not because of individual differences with respect to gender, tendency to regret, or tendency to maximize. Previous studies have found that those who change from a correct to wrong option regret more than those who select a wrong option directly. This study indicates that this finding is a special case of a more general phenomenon: changing one's mind seems to come with a cost, even when one ends up with favorable outcomes.

Assessment of risk is one of the key issues in the field of responsible conduct of research which covers discourses of research ethics and research integrity. The principle of minimizing risks and balancing of risks and benefits is one of the main requirements of research ethics. In addition, the content of informed consent that is another fundamental principle of research ethics derives from the assessment of risks and benefits related to a particular research project. Risk assessment also plays a crucial role in methodological design of the research project. This is an important point where research ethics and research integrity discourses overlap. Firstly, because the choice of a control group (e.g., placebo control) is a key ethical issue related to the protection of the research subjects' interests. Secondly, because the quality of the research data, that is one of the key elements of research integrity, is closely connected to the choice of research methodology as well. The problem of biased interpretation or manipulation of risk related features of biomedical research should also be taken into account. Despite the importance of the concept of risk to the field of biomedical research, its relevance has not yet attracted a sufficient attention in the responsible conduct of research debate. 相似文献

An honor code is certainly a good place to start teaching engineering students about ethics, but teaching students to live
honorably requires far more effort than memorizing a code of ethics statement or applying it just to academic performance.
In the School of Engineering at Grand Valley State University, we have followed the model provided by the United States Military
Academy at West Point. For our students this involves an introduction to the Honor Code as part of a larger Honor Concept
at the very beginning of their studies and then making it an integral part of their preparation as engineers. The challenge
is significant because the culture at large does not support living with an Honor Concept. This paper will begin with a discussion
of the cultural context in which we must teach, because that context has changed significantly in the years since many faculty
members were students themselves. The rest of the paper will detail the approach that we have taken to teach ethics as an
engineer’s way of life.
“The shortest and surest way to live with honor in the world is to be in reality what we would appear to be. All human virtues
increase and strengthen themselves by the practice and experience of them.”

This study compared the disfluencies of German-speaking preschool children who stutter (CWS, N = 24) with those produced by age- and sex-matched comparison children who do not stutter (CWNS, N = 24). In accordance with Yairi and Ambrose's [Yairi, E., & Ambrose, N. (1992). A longitudinal study of stuttering in children: A preliminary report. Journal of Speech and Hearing Research, 35, 755-760] guidelines the CWS group had a narrow age range (2-5 years) and were seen close to the reported time of their stuttering onset (average of 8 months). Furthermore, over 95% of the CWS group had not received any type of speech therapy intervention. Consistent with previous findings for English-speaking preschool children, 'stuttering-like' disfluencies (prolongations, blocks, part- and one-syllable word repetitions) were significantly more frequent in CWS (mean = 9.2%) than in CWNS (mean = 1.2%), whereas no significant group differences occurred with respect to 'normal' disfluencies. The number of iterations in stuttering-like disfluencies was also significantly higher in CWS (mean = 1.28 iterations) than in CWNS (mean = 1.09 iterations). In contrast to previous findings, a sub-group of children who have been stuttering for a shorter time (1-5 months) did not differ from a sub-group who had stuttered for a longer period (8-22 months). EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe how German-speaking preschool children who stutter and who do not stutter display stuttering-like and normal disfluencies including number of iterations; (2) explain how powerful classification measures for the diagnosis of stuttering are for German-speaking preschool children; (3) discuss how disfluency patterns of native English- and German-speaking children close to onset of stuttering differ. 相似文献

The capacity to think about specific events that one might encounter in the future—episodic future thought— involves the flexible
(re)organization of memory. The present study demonstrates that implicit processes play an important role here. In two experiments
(N = 180), participants were asked to generate a personal event that they expected to plausibly occur in the following week.
The content of the participants’ responses was biased (i.e., primed) by recent thoughts about a specific category of experiences.
For instance, participants who had recently been induced to think about social experiences, in the context of an ostensibly
unrelated task, were more likely than nonprimed participants to generate similar events occurring in their immediate future.
Importantly, the participants were unaware of this unintentional influence of memory. The theoretical and practical implications
of these findings for understanding episodic future thought and its relation to memory are discussed. 相似文献
