Individual Differences in Interpersonal Accuracy: A Multi-Level Meta-Analysis to Assess Whether Judging Other People is One Skill or Many

Research into individual differences in interpersonal accuracy (IPA; the ability to accurately judge others’ emotions, intentions, traits, truthfulness, and other social characteristics) has a long tradition and represents a growing area of interest in psychology. Measuring IPA has proved fruitful for uncovering correlates of this skill. However, despite this tradition and a considerable volume of research, very few efforts have been made to look collectively at the nature of the tests involved in assessing IPA, leaving questions of the broader structure of IPA unresolved. Is IPA a single skill or a clustering of many discrete skills or some combination of partially overlapping skills? In a multi-level meta-analysis of 103 published and unpublished participant samples (13,683 participants), we analyzed 622 correlations between pairs of IPA tests (135 different IPA tests altogether). The overall correlation between IPA tests was r = .19, corrected for the nesting of correlations within the studies that administered more than two IPA tests and reported several correlations for the same participant sample. Test domain and characteristics were evaluated to explain differences in effect sizes; in general, tests in similar domains and using similar methodologies were more highly correlated with each other, suggesting that there are domains within which individual differences cluster. Implications for future research and IPA measurement were discussed.     

The asymptotic behaviour of the residual sum of squares in models with multiple break points

ABSTRACT

Models with multiple discrete breaks in parameters are usually estimated via least squares. This paper, first, derives the asymptotic expectation of the residual sum of squares and shows that the number of estimated break points and the number of regression parameters affect the expectation differently. Second, we propose a statistic for testing the joint hypothesis that the breaks occur at specified points in the sample. Our analytical results cover models estimated by the ordinary, nonlinear, and two-stage least squares. An application to U.S. monetary policy rejects the assumption that breaks are associated with changes in the chair of the Fed.

Extended-family resources and racial inequality in the transition to homeownership

We use longitudinal data from the Panel Study of Income Dynamics to examine how access to financial resources in the extended family affects the accumulation of wealth among non-owners and how these resources subsequently affect transitioning into homeownership. Our findings show that economic conditions of the extended family have substantial effects on non-owners’ wealth accumulation and likelihood of becoming homeowners, even after adjusting for individual sociodemographic and economic characteristics. We find significant effects of extended-family wealth for both black and white households, but effects of extended-family income insufficiency for blacks only. Consequently, limited access to wealth and greater level of poverty in the extended family hamper blacks’ transition to homeownership. Our results show that the level of extended-family wealth necessary for black householders to equalize their likelihood of becoming homeowners with whites is very high. In fact, our findings indicate that white householders embedded in extended families with no net wealth are just as likely to make the transition to ownership as are black householders with affluent extended families. These findings support arguments related to the importance of extended-family resources in processes of residential attainment but also point to important racial differences in not only levels but also consequences of these family resources.     

Anti-Semitism and Identification of Jewish Group Membership from Photographs

Early literature found that holding more anti-Semitic attitudes positively predicted ability to discern whether a photograph was of a Jewish or non-Jewish person. This contradicts the well established finding that interpersonal sensitivity is generally associated with healthy psychological characteristics. In five new, previously unpublished studies we found that this relation was negative, such that more prejudiced individuals were now less accurate than less prejudiced individuals at a similar task, consistent with the general finding. A meta-analysis of all the studies showed that time was a significant moderator of the relation. Possible reasons for the temporal change are discussed.

Does Human Capital Raise Earnings for Immigrants in the Low-Skill Labor Market?

We use monthly Survey of Income and Program Participation data from 1996–1999 and 2001–2003 to estimate the determinants of differentiation in intercepts and slopes for age/earnings profiles of low-skill immigrant and native male workers. Our findings provide further depth of understanding to the“mixed” picture of earnings determination in the low-skill labor market that has been reported by others. On the positive side, many immigrants are employed in similar occupations and industries as natives. Both groups show substantial wage gains over time and generally receive similar returns to years of schooling completed. Immigrants also receive substantial returns to acculturation, measured as age at arrival and English language skill. These results cast doubt on the strong version of segmented labor market theory, in which low-skill immigrants are permanently consigned to dead-end jobs with no wage appreciation. On the negative side, immigrants earn approximately 24% less than natives and are less likely to occupy supervisory and managerial jobs. Latino immigrants receive lower returns to education than do white immigrants. Furthermore, age at arrival and language ability do not explain the lower returns to education experienced by Latino immigrants. These results suggest that Latino immigrants in particular may suffer from barriers to mobility and/or wage discrimination. Whether these negative labor market experiences occur primarily for illegal immigrants remains unknown.     

SEMIPARAMETRIC COMPARISON OF REGRESSION CURVES VIA NORMAL LIKELIHOODS

Härdle & Marron (1990) treated the problem of semiparametric comparison of nonparametric regression curves by proposing a kernel-based estimator derived by minimizing a version of weighted integrated squared error. The resulting estimators of unknown transformation parameters are n-consistent, which prompts a consideration of issues. of optimality. We show that when the unknown mean function is periodic, an optimal nonparametric estimator may be motivated by an elegantly simple argument based on maximum likelihood estimation in a parametric model with normal errors. Strikingly, the asymptotic variance of an optimal estimator of θ does not depend at all on the manner of estimating error variances, provided they are estimated n-consistently. The optimal kernel-based estimator derived via these considerations is asymptotically equivalent to a periodic version of that suggested by Härdle & Marron, and so the latter technique is in fact optimal in this sense. We discuss the implications of these conclusions for the aperiodic case.     

Occupational Cultures and the Embodiment of Masculinity: Hairdressing,Estate Agency and Firefighting

Drawing on data from an Economic and Social Research Council‐funded project, this article explores the implications of different occupational cultures for men's masculine identity. With a focus on embodiment and individual agency, it explores the argument that it is within ‘scenes of constraint’ that gendered identities are both ‘done’ and ‘undone’. In this article we examine embodied experience in occupational cultures commonly stereotyped as ‘masculine’ or ‘feminine’ (hairdressing, estate agency and firefighting), showing how men conform to, draw upon and resist the gendered stereotypes associated with these occupations. What we argue is that gendered conceptions of ‘the body’ need to be differentiated from individual men's embodiment. Instead, processes of identification can be shown to emerge via embodied experiences of particular kinds of gendered body, and in the ways in which men negotiate the perception of these bodies in different occupational contexts.
