沉没成本效应是指决策者的决策行为因受沉没成本影响而产生的一种非理性决策现象。针对这一决策偏差的产生根源,研究者从认知、动机和神经三个角度提出了解释。沉没成本效应的影响因素包括沉没成本特性、情境因素、个体差异和文化差异等。基于先前研究存在的问题和不足,沉没成本效应的未来研究应着眼于改进研究方法,探究产生根源,关注行为沉没成本和加强应用研究。  相似文献

Do skilled readers of opaque and transparent orthographies make differential use of lexical and sublexical processes when converting words from print to sound? Two experiments are reported, which address that question, using effects of letter length on naming latencies as an index of the involvement of sublexical letter–sound conversion. Adult native speakers of English (Experiment 1) and Spanish (Experiment 2) read aloud four- and seven-letter high-frequency words, low-frequency words, and nonwords in their native language. The stimuli were interleaved and presented 10 times in a first testing session and 10 more times in a second session 28 days later. Effects of lexicality were observed in both languages, indicating the deployment of lexical representations in word naming. Naming latencies to both words and nonwords reduced across repetitions on Day 1, with those savings being retained to Day 28. Length effects were, however, greater for Spanish than English word naming. Reaction times to long and short nonwords converged with repeated presentations in both languages, but less in Spanish than in English. The results support the hypothesis that reading in opaque orthographies favours the rapid creation and use of lexical representations, while reading in transparent orthographies makes more use of a combination of lexical and sublexical processing.  相似文献

Although recent studies have shown cross-cultural differences in theory of mind (ToM) between children in Western and Eastern cultures, little is known about cross-cultural differences pertaining to social correlates. The present research investigated cultural variations in the relationship between sensitivity to criticism and ToM. Japanese (n = 76) and Italian (n = 76) 6-year-olds completed a sensitivity-to-criticism task (either the teacher condition or the peer condition), second-order false-belief tasks, and a verbal ability test. The results replicated previous findings of an association between ability rating after teacher criticism and ToM in both countries. Cultural variation was found in emotional response and motivation after teacher, but nor peer, criticism. Japanese children responded to teacher criticism more positively than did Italian children. Moreover, Japanese children who failed the second-order false-belief task were more motivated after teacher criticism than were Italian children. These results are discussed in relation to differences in cultural factors.  相似文献

Abstract

Research on the relationship of client hope to successful therapy outcome underlines the need to discover the processes and conditions when hope flourishes. Snyder’s Hope Theory has been applied to psychotherapy but client subjective experiences are needed to illuminate nuances in the process. The present study examined the trajectory of hope development in psychotherapy using interviews with 18 counseling clients, analyzed using grounded theory methodology. Findings were synthesized into a dynamic model titled hope as empowerment model (HEM) that shares features of Snyder’s Hope Theory. HEM introduces patterns of particular salience to psychotherapy. The compatibility of client preferences with therapist input raised faith in the process of counseling and, in turn, hope in a positive outcome. A number of conditions, including the flexibility of client role preferences and the directiveness of hope-inspiring therapeutic strategies, influenced the nature and strength of client hope. Implications for therapy and positive psychology are considered.  相似文献

Career adaptivity is the first factor in a chain of putative effects posited in the career construction theory (CCT): Adaptivity → Adaptability → Adapting  Adaptation. Hitherto, research on adaptivity has chiefly used variable-centered strategies to investigate the independent effects of adaptivity-related traits on adaptability, adapting, and adaptation averaged over all individuals constituting a sample. The present research, comprising two studies, seeks to extend this work by using person-centered analytic strategies to identify distinct profiles of adaptivity based on combinations of the Big-Five personality dimensions. We also examine the associations of profile membership with adaptability, adapting, and adaptation from the CCT perspective. Latent profile analyses revealed that a comparable 3-profile solution, comprising so-called “adaptive ready”, “ordinary”, and “rigid” adaptivity profiles, fit best in both studies using distinct measures of the Big-Five. Furthermore, across both studies, the latent subgroups were found to differ on levels of adaptability measured using two distinct instruments. Adaptability was highest in the “adaptive ready” subgroup followed by the “ordinary” and “rigid” subgroups, respectively. Finally, Study 2 showed that the adaptivity profiles differed with respect to indices of adapting (viz., organized study behaviors) and adaptation (viz., academic and career-choice satisfaction) in line with expectations from the CCT. The present findings constitute the first evidence showing that career adaptivity can be adequately represented via trait interactions. The findings also add to the empirical literature underpinning the CCT. Furthermore, this research is an informative demonstration of the utility of finite mixture analyses.  相似文献

Considering the impostor phenomenon (IP) as an important psychological construct in the context of career development requires a theoretical grounding. Using the career construction model of adaptation as a guiding framework, we investigated how the IP is related to adaptive readiness (represented by core self-evaluations), career adaptability resources, and adapting responses, namely, career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. We used parallel multiple mediation modeling to investigate specific indirect effects through concern, control, curiosity, confidence, and the IP. We conducted an online study with 289 university students. Results indicated a positive effect of core self-evaluations on career planning, career exploration, and occupational self-efficacy and a negative effect on career decision-making difficulties through adaptability resources. The IP emerged as a “maladaptability” resource: That is, it might be a hindrance to adaptive coping and behavior and consequently promote maladaptive coping and behavior by decreasing career planning and occupational self-efficacy and increasing career decision-making difficulties. Supplementary negative effects of the IP on adaptability resources are discussed.  相似文献

Some environmental ethicists and economists argue that attributing infinite value to the environment is a good way to represent an absolute obligation to protect it. Others argue against modelling the value of the environment in this way: the assignment of infinite value leads to immense technical and philosophical difficulties that undermine the environmentalist project. First, there is a problem of discrimination: saving a large region of habitat is better than saving a small region; yet if both outcomes have infinite value, then decision theory prescribes indifference. Second, there is a problem of swamping probabilities: an act with a small but positive probability of saving an endangered species appears to be on par with an act that has a high probability of achieving this outcome, since both have infinite expected value. Our paper shows that a relative (rather than absolute) concept of infinite value can be meaningfully defined, and provides a good model for securing the priority of the natural environment while avoiding the failures noted by sceptics about infinite value. Our claim is not that the relative infinity utility model gets every detail correct, but rather that it provides a rigorous philosophical framework for thinking about decisions affecting the environment.  相似文献

Examinee‐selected item (ESI) design, in which examinees are required to respond to a fixed number of items in a given set, always yields incomplete data (i.e., when only the selected items are answered, data are missing for the others) that are likely non‐ignorable in likelihood inference. Standard item response theory (IRT) models become infeasible when ESI data are missing not at random (MNAR). To solve this problem, the authors propose a two‐dimensional IRT model that posits one unidimensional IRT model for observed data and another for nominal selection patterns. The two latent variables are assumed to follow a bivariate normal distribution. In this study, the mirt freeware package was adopted to estimate parameters. The authors conduct an experiment to demonstrate that ESI data are often non‐ignorable and to determine how to apply the new model to the data collected. Two follow‐up simulation studies are conducted to assess the parameter recovery of the new model and the consequences for parameter estimation of ignoring MNAR data. The results of the two simulation studies indicate good parameter recovery of the new model and poor parameter recovery when non‐ignorable missing data were mistakenly treated as ignorable.  相似文献
