Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986) . The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well‐known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum‐likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E‐step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by‐products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example. 相似文献

The present study examined the role of prebirth parent characteristics as predictors of maternal gatekeeping (mothers' attempts to encourage or discourage fathers' interaction with their infant) and fathering behavior. Parents' idealization of their relationships within their families of origin, beliefs about the roles of fathers, and personality attributes (negative emotionality and communion) were assessed before their infant's birth. At 3.5 months postpartum, maternal gatekeeping behaviors (negative control, facilitation) and fathers' involvement and competence with their infants were assessed during observation of triadic play and child care. Results suggest reciprocal relations between maternal gatekeeping and fathering behavior. Furthermore, greater paternal communion was associated with greater paternal competence during play, whereas greater maternal communion was associated with lower paternal competence during child care. Greater maternal communion and greater maternal idealization related to fathers' lower relative involvement during play. As for maternal gatekeeping behavior, high negative emotionality in 1 parent was only accompanied by high levels of inhibitory maternal gatekeeping when the other parent had less progressive beliefs about the father's role. The implications of these findings for clinicians and practitioners are discussed. 相似文献

Firms allocate considerable resources to test job applicants' skills and to ensure that hiring decisions are nondiscriminatory. Interpreting selection output in light of preliminary information may undermine the impartiality of personnel selection decisions. In this study, human resource managers were presented preliminary information about a candidate's performance and asked to rate him according to a detailed assessment‐center report of his performance. We examined several interventions for reducing reliance on preliminary information: retrieving assessment‐center information, generating a rating model, or both. Participants (N = 167) excluded preliminary information from the interventions, but relied on it when rating the candidate. The documented failure to control for the effects of preliminary information on subsequent judgments can contribute to improved selection procedures. 相似文献

We examined the longitudinal effects of situationally induced 2‐dimensional state goal orientations (i.e., achievement goals) on perceptions, performance, and satisfaction. Results (N = 268) indicated that high state learning cues led to higher perceived challenge and, for higher ability individuals, greater performance gains. Further, high state performance cues led to higher perceived effort. However, results revealed that state learning and performance effects were more complex than expected. State learning effects on challenge and state performance effects on effort were both stronger with other cues absent. Additionally, increasingly beneficial state learning cue effects were stronger for higher ability individuals. Thus, results provided support that state learning and performance goals are separate dimensions, and their interactive effects need further examination. 相似文献

Two experiments examined reactions to line‐intrusion scenarios among fans of the rock group U2 waiting in overnight lines to obtain desirable concert floor spots. Commitment to the goal, time investment, and ambiguity of the line‐intrusion scenario were examined. Results showed that the queue is a social system influenced by norms of procedural justice (first‐come, first‐served). Violations of these norms were upsetting, even when the consequences did not directly influence personal outcomes (when line intrusions occurred behind a subject). Greater commitment to the goal led to more severe reactions to norm violations, whether the commitment was proximal (having waited in the line for awhile) or distal (being a committed fan). We discuss research on social norm violations. 相似文献

Age‐related differences in cognitive processes were used to understand age‐related declines in creativity. According to the Geneplore model (Finke, Ward, & Smith, 1992), there are two phases of creativity — generating an idea and exploring the implications of the idea — each with different underlying cognitive processes. These two phases are measured in the Creative Invention Task (CIT; Finke, 1990). Younger adults (n = 41) and older adults (n = 41) completed the CIT, the Torrance Tests of Creative Thinking (TTCT), and a measure of working memory capacity (Paper Folding test). In addition, the CIT was scored by both younger and older adults. There were age‐related declines on both phases of the CIT, but not on the TTCT. These declines were noted by both the younger and older raters. After adjusting for working memory capacity, however, age‐related differences on the CIT were nonsignificant. 相似文献

Research on the phenomenon of selective exposure to information demonstrates that after preliminary or final decisions, people show a preference for supporting rather than conflicting information (confirmation bias). In this article, we examine conditions that increase or decrease distortions in the search for information. We report on four experiments indicating that the confirmation bias is influenced by whether people focus on their decision or on the presented pieces of information during the information search. Focusing on the decision, for example, because a reward for a correct decision is promised or simply because participants repeatedly think of it, increases the confirmation bias. On the other hand, if participants focus on the available pieces of information because they have to invest money in order to search for information or because they have to evaluate the individual pieces of information, the confirmation bias decreases. Implications for theoretical understanding and interventions for decision-making situations are discussed. 相似文献
