Overconfidence and underconfidence: When and why people underestimate (and overestimate) the competition 总被引:5,自引:0,他引:5
Don A. Moore Daylian M. Cain 《Organizational behavior and human decision processes》2007,103(2):197-213
It is commonly held that people believe themselves to be better than others, especially for outcomes under their control. However, such overconfidence is not universal. This paper presents evidence showing that people believe that they are below average on skill-based tasks that are difficult. A simple Bayesian explanation can account for these effects and for their robustness: On skill-based tasks, people generally have better information about themselves than about others, so their beliefs about others’ performances tend to be more regressive (thus less extreme) than their beliefs about their own performances. This explanation is tested in two experiments that examine these effects’ robustness to experience, feedback, and market forces. The discussion explores the implications for strategic planning in general and entrepreneurial entry in particular. 相似文献

We reviewed the Spanish translation of the Youth Quality of Life Instrument-Research Version (YQOL-R) and culturally adapted
the measure with Puerto Rican and Mexican American children and adolescents. The YQOL-R is a self-reported measure that includes
four domains: Sense of Self, Social Relationships, Environment, and General Quality of Life. A total of 10 focus groups were
conducted with children aged 9 to 11, adolescents aged 12 to 17, their parents, and mental health providers. Five focus groups
were conducted in San Diego, California and five in San Juan, Puerto Rico. Eligible participants were recruited from children’s
outpatient psychiatry clinics. We followed an iterative and recursive process in reviewing changes and modifications to the
instrument using a bilingual committee and a Multi National Bilingual Committee. Greater semantic, content, and technical
equivalence of the Spanish and English versions for the YQOL-R was achieved for the two largest U.S. Latino subgroups: Mexican
Americans and Puerto Ricans. The cultural adaptation process revealed several important issues regarding the measurement of
quality of life in different age groups. Additional items for school, relationships (both family and friends) and spare time
suggested the need for a future children’s version of the instrument. For the adolescents, additional items were suggested
in the areas of sexuality, intergenerational conflict and acculturative stress. 相似文献

The article first rehearses three deflationary theories of reference, (1) disquotationalism, (2) propositionalism (Horwich),
and (3) the anaphoric theory (Brandom), and raises a number of objections against them. It turns out that each corresponds
to a closely related theory of truth, and that these are subject to analogous criticisms to a surprisingly high extent. I
then present a theory of my own, according to which the schema “That S(t) is about t” and the biconditional “S refers to x
iff S says something about x” are exhaustive of the notions of aboutness and reference. An account of the usefulness of “about”
is then given, which, I argue, is superior to that of Horwich. I close with a few considerations about how the advertised
theory relates to well-known issues of reference, the conclusions of which is (1) that the issues concern reference and aboutness
only insofar as the words “about” and “refer” serve to generalise over the claims that are really at issue, (2) that the theory
of reference will not settle the issues, and (3) that it follows from (2) that the issues do not concern the nature of aboutness
or reference. 相似文献

Two studies demonstrate that members of high-status groups (i.e., men and students of business administration) but not members of low-status groups (i.e., women and education students) react with an increase in state self-esteem after an alleged poor performance on a fictitious intelligence test. This Failure-as-an-Asset (FA) effect is only observed when the high-status ingroup (i.e., men) is outperformed by a low-status outgroup (i.e., women). In this case, a poor performance will lead to a strong identification with the ingroup due to high ingroup prototypicality. As predicted, the effects of experiencing success or failure on self-esteem were mediated by identification with the ingroup. 相似文献

Two studies investigated the role of beliefs about the acceptability of aggression (“normative beliefs”) against Jews in determining who would join an extremist group. In Study 1, students in a university in Pakistan (N=144) completed self‐report attitude measures, and were subsequently approached by a confederate who asked whether they wanted to join an extremist anti‐Semitic organization. Normative beliefs about aggression against Jews were very strong predictors of whether participants agreed to join. In Study 2, participants (N=92) were experimentally assigned to either a brief educational intervention, designed to improve inter‐group relations, or to a control group. They also filled in self‐report attitude measures pre and post intervention. Participants in the intervention group were much less likely to agree to join the extremist group, and this effect of the intervention on joining was mediated by changes in normative beliefs about aggression against Jews. The results have implications for theories of inter‐group aggression and interventions to prevent people from being recruited into extremist groups. Aggr.

There is a nascent, but growing, literature on Southeast Asian youth violence that focuses on the role of acculturation, portraying violence as a problem of maladaptation. However, scholars overlook the ways in which violence holds meaning for the youth who experience it and how violence may be related to racial and gender identity formation. We conducted a qualitative study with young Southeast Asian men to elicit the role violence plays in their understanding of what it means for them to be Southeast Asian and male. We conducted focus groups and semi-structured individual interviews with an ethnically diverse group of 21 young Southeast Asian men 13–17 years of age from Alameda and Contra Costa Counties, California. Data were analyzed using the extended case method approach. Our findings illustrate that violence and engagement with community-based organizations are situational tools that these young Southeast Asian men use to navigate their social contexts in an attempt to be resilient in ecological contexts marked by alienation and discrimination, as well as to construct accepted and successful racial and gender identities. Furthermore, we found that their actions were guided by gendered codes of conduct, such as a “code of the street.” 相似文献

The lattices of varieties were studied in many works (see [4], [5], [11], [24], [31]). In this paper we describe the lattice
of all subvarieties of the variety defined by so called externally compatible identities of Abelian groups and the identity x

This study examined what parents of children with disabilities and special needs found helpful about belonging to mutual support groups. Quantitative data (based on 56 parents from 6 groups) indicated that members found the groups very helpful and were very satisfied with the support they received from their groups; they also described the groups as high in cohesion, expressiveness, task orientation, and self-discovery. A grounded theory analysis of focus group data (based on 43 parents from 5 of the groups) indicated that such support was helpful in three broad domains: (1) the sociopolitical, which involved developing a sense of control and agency in the outside world; (2) the interpersonal, which involved asense of belonging to a community; and (3) the intraindividual, which involved self change. A central theme of identity change emerged as superordinate to these three categories. 相似文献

MAU程序和自由讨论的群体决策质量比较 总被引:5,自引:0,他引:5
采用实验室研究方法,比较了在信启、不分享条件下多特征效用模型(MAU)决策程序和自由讨论对群体决策质量的影响,并对影响MAU决策质量的主要因素进行了初步探讨。结果发现:(1)MAU程序可以较好地克服群体动力学方面的一些消极影响,表现出挖掘信息(尤其是非分享信息)的充分性。但MAU程序在被试的态度和社会交互作用等心理效标上并未显示出优势;(2)在MAU条件下,群体规模的增大对分享和非分享信息的讨论量无显著影响。而任务难度效应要和群体规模一起才能起到作用。 相似文献
