Partridge and Lerner (2007), in a secondary analysis of the New York Longitudinal Study, employed a chronometric polynomial growth curve model to argue that the developmental course of difficult temperament follows a non‐linear trajectory over the first 5 years of life. The free curve slope intercept (FCSI) growth curve model of Meredith and Tisak (1990) is presented as a preferable conceptual alternative because it contains a number of currently popular statistical models, including repeated measures multivariate analysis of variance, factor mean, linear growth, linear factor analysis, and hierarchical linear models as special cases. As such, researchers can compare the fit of each of these models relative to the FCSI model, and, at times, to each other. The present paper conducts a re‐analysis of the data, and establishes that fit of the FCSI model is arguably better than other statistical alternatives. The FCSI model is also used as the basis for identifying subgroups of individuals with their qualitatively distinct growth patterns within a growth mixture modeling framework.

We examine the influence of contrast categories on the internal graded membership structure of everyday concepts using computational models proposed in the artificial category learning tradition. In particular, the generalized context model (Nosofsky, 1986), which assumes that only members of a given category contribute to the typicality of a category member, is contrasted to the similarity–dissimilarity generalized context model (SD-GCM; Stewart & Brown, 2005), which assumes that members of other categories are also influential in determining typicality. The models are compared in a hierarchical Bayesian framework in their account of the typicality gradient of five animal categories and six artefact categories. For each target category, we consider all possible relevant contrast categories. Three separate issue are examined: (a) whether contrast effects can be found, (b) which categories are responsible for these effects, and (c) whether more than one category influences the typicality. Results indicate that the internal category structure is codetermined by dissimilarity towards potential contrast categories. In most cases, only a single contrast category contributed to the typicality. The present findings suggest that contrast effects might be more widespread than has previously been assumed. Further, they stress the importance of characteristics particular of everyday concepts, which require careful consideration when applying computational models of representation of the artificial category learning tradition to everyday concepts. 相似文献

The present study examined the prevalence of cross-race interactions occurring in daily life using wearable camera technology that captures photographs of a participants’ immediate environment and social interactions. Coders used appearance-based cues to identify the number of interaction partners captured in the photos who appeared to be White or a racial minority. We found that 29.6% of Whites’ social interactions were with racial minorities and 23.9% of racial minorities’ social interactions were with Whites. Furthermore, we examined whether personality and other individual differences correlated with being captured in more cross-race interactions. We found that Whites who used more emotion-focused coping and less emotional suppression were more likely to be captured engaging in cross-race interactions. 相似文献

Functional analysis results for multiple topographies of aberrant behavior were graphed in an aggregate fashion and then separately for 48 clients. The results indicated that multiple topographies of behavior may be maintained by different contingencies. These results indicate that graphing functional analysis data in an aggregate fashion and then separately may improve the accuracy of their interpretation. 相似文献

Multilevel covariance structure models have become increasingly popular in the psychometric literature in the past few years
to account for population heterogeneity and complex study designs. We develop practical simulation based procedures for Bayesian
inference of multilevel binary factor analysis models. We illustrate how Markov Chain Monte Carlo procedures such as Gibbs
sampling and Metropolis-Hastings methods can be used to perform Bayesian inference, model checking and model comparison without
the need for multidimensional numerical integration. We illustrate the proposed estimation methods using three simulation
studies and an application involving student's achievement results in different areas of mathematics.

This study aimed to assess the longitudinal associations between the 1973 Israeli-Arab War ex-prisoners of war’s (ex-POWs) posttraumatic stress disorder symptoms (PTSS) and dyadic adjustment (DAS) and their adult offspring’s secondary PTSS and DAS. A sample of 124 Israeli father–child dyads has been examined (fathers at 2003 and 2008; offspring at 2013–2014). Results show that fathers’ PTSS and DAS mediated the link between war captivity and offspring’s secondary PTSS and DAS, respectively. The intergenerational transmission of captivity trauma is indirectly explained by the long-term effects of the fathers’ PTSS on their offspring’s secondary PTSS and DAS. 相似文献
