This article examines the professional valorisation of gender-typed traits. In the study, participants should assess masculine, feminine and androgynous profiles in a set of professional contexts obtained by the crossing of social status (high versus low), gender (masculine versus feminine) and sector (production versus maintenance) of occupations. Consistent with a gender- typed trait matching model, the results showed that masculine profiles were the most valued ones in the most masculine occupations, feminine profiles were mostly valued in the most feminine occupations while androgynous profiles were the most valued in gender ambiguous occupations. Of particular interest was the fact that the perception of occupations’ gender was a function of the interaction between the gender and the sector of occupations (i.e.: the most masculine occupations were those that were stereotypically masculine and belonging to the production sector; the most feminine were those that were stereotypically feminine and belonging to the maintenance sector; the stereotypically masculine and maintenance occupations as the stereotypically feminine and production occupations were perceived as less gender typed). 相似文献

决策策略与个性特征关系的模拟实验 总被引:3,自引:0,他引:3
本研究以实验室模拟实验和现场模拟实验为手段,以大学本科生和工厂管理人员为被试,分两部分进行。第一部分,以企业新产品开发为决策内容,考察这类决策情景的不确定性和决策策略的关系。结果发现,决策策略随不确定状态而改变;决策情景的不确定程度和决策策略没有严格的一一对应关系;在四类不确定决策情景下,都有被试采用混合型策略,从而验证了先前研究的结果。第二部分,我们考察了决策策略与个性特征的关系。结果发现,偏离决策策略的规定性理论所预测的被试同没有偏离的被试在CPI量表的三种个性特征上,即成熟度、成就动机与管理潜能,有显著性差异;对实验室实验被试和现场实验被试而言,均发现管理潜能这一个性特征一致性的显著影响。文章最后提出了有待进一步探索的课题。 相似文献

In tailored testing, it is important to determine the optimal difficulty of the next item to present to the examinee. This paper shows that the difference that maximizes information for the three-parameter normal ogive response model is approximately 1.7 times the optimal difference –b for the three-parameter logistic model. Under the normal model, calculation of the optimal difficulty for minimizing the Bayes risk is equivalent to maximizing an associated information function.The views expressed herein, are those of the author and do not necessarily reflect those of the Department of the Navy. 相似文献

Samejima has recently given an approximation for the bias function for the maximum likelihood estimate of the latent trait in the general case where item responses are discrete, generalizing Lord's bias function in the three-parameter logistic model for the dichotomous response level. In the present paper, observations are made about the behavior of this bias function for the dichotomous response level in general, and also with respect to several widely used mathematical models. Some empirical examples are given. 相似文献

Lord developed an approximation for the bias function for the maximum likelihood estimate in the context of the three-parameter logistic model. Using Taylor's expansion of the likelihood equation, he obtained an equation that includes the conditional expectation, given true ability, of the discrepancy between the maximum likelihood estimate and true ability. All terms of orders higher thann ?1 are ignored wheren indicates the number of items. Lord assumed that all item and individual parameters are bounded, all item parameters are known or well-estimated, and the number of items is reasonably large. In the present paper, an approximation for the bias function of the maximum likelihood estimate of the latent trait, or ability, will be developed using the same assumptions for the more general case where item responses are discrete. This will include the dichotomous response level, for which the three-parameter logistic model has been discussed, the graded response level and the nominal response level. Some observations will be made for both dichotomous and graded response levels. 相似文献

在经典真分数模型中,信度系数R=D(T)/D(X)。通常认为,信度系数与项目反应理论没有什么联系。事实上,信度系数恰好等于考生观测分数与潜在特质分数的非线性相关比η_(xθ)~2=1-MD(x|θ)/D(X),据此我们得出估计信度系数的一种新途径,同时讨论了x、θ的相关系数与相关比η_(xθ)~2的关系。 相似文献

本研究采用经典内隐联想测验任务,研究了现在享乐、现在宿命和未来三种时间洞察力特质中学生的健康行为选择内隐偏好以及未来情景性思维在时间洞察力类型与健康行为选择内隐偏好中的调节作用。结果发现:未来特质中学生的健康行为选择内隐偏好高于现在享乐和现在宿命特质中学生;未来情景性思维水平在中学生时间洞察力类型与健康行为选择内隐偏好的关系中起调节作用,即未来情景性思维显著提高现在享乐和未来特质中学生的健康行为选择内隐偏好,而对现在宿命特质的作用不显著。本研究的发现表明未来时间洞察力特质是中学生选择健康行为的积极因素;未来情景性思维能促进现在享乐和未来时间洞察力特质中学生的健康行为选择内隐偏好。 相似文献

In their comprehensive review of research on impressions from faces, Sutherland and Young (this issue) highlight both the remarkable progress and the many challenges facing the field. We focus on two of the challenges: the need for generative, powerful models of impressions and the idiosyncratic nature of complex impressions. 相似文献
