An extension of component analysis to longitudinal or cross-sectional data is presented. In this method, components are derived under the restriction of invariant and/or stationary compositing weights. Optimal compositing weights are found numerically. The method can be generalized to allow differential weighting of the observed variables in deriving the component solution. Some choices of weightings are discussed. An illustration of the method using real data is presented.Preparation of this article was supported in part by PSC-CUNY Grant #665365 to Roger E.

A closed form estimator of the uniqueness (unique variance) in factor analysis is proposed. It has analytically desirable properties—consistency, asymptotic normality and scale invariance. The estimation procedure is given through the application to the two sets of Emmett's data and Holzinger and Swineford's data. The new estimator is shown to lead to values rather close to the maximum likelihood estimator. 相似文献

According to the theory of Universal Grammar, the primary linguistic data guides children through an innately specified space of hypotheses. On this view, similarities between child-English and adult-German are as unsurprising as similarities between cousins who have never met. By contrast, experience-based approaches to language acquisition contend that child language matches the input, with nonadult forms being simply less articulated versions of the forms produced by adults. This paper reports several studies that provide support for the theory of Universal grammar, and resist explanation on experience-based accounts. Two studies investigate English-speaking children’s productions, and a third examines the interpretation of sentences by Japanese speaking children. When considered against the input children are exposed to, the findings of these and other studies are consistent with the continuity hypothesis, which supposes that child language can differ from the language spoken by adults only in ways that adult languages can differ from each other. 相似文献

On cyclic-interval reinforcement schedules, animals typically show a postreinforcement pause that is a function of the immediately preceding time interval (temporal tracking). Animals, however, do not track single-alternation schedules-when two different intervals are presented in strict alternation on successive trials. In this experiment, pigeons were first trained with a cyclic schedule consisting of alternating blocks of 12 short intervals (5 s or 30 s) and 12 long intervals (180 s), followed by three different single-alternation interval schedules: (a) 30 s and 180 s, (b) 5 s and 180 s, and (c) 5 s and 30 s. Pigeons tracked both schedules with alternating blocks of 12 intervals. With the single-alternation schedules, when the short interval duration was 5 s, regardless of the duration of the longer interval, pigeons learned the alternation pattern, and their pause anticipated the upcoming interval. When the shorter interval was 30 s, even when the ratio of short to long intervals was kept at 6:1, pigeons did not initially show anticipatory pausing-a violation of the principle of timescale invariance. 相似文献

Fantasy-prone personalities and generalized states of pessimism and hopelessness have been linked to various behavioural, cognitive, and health related outcomes in the general population. Nevertheless, to date, knowledge of sport-specific fantasy proneness and athletes’ perception of deflated reality in sport is scarce, possibly due to a lack of appropriate psychometric instruments to examine these two important context-specific constructs. In this research, we developed the Sport Fantasy Proneness Scale (SFPS) and the Deflated Reality in Sport Scale (DRSS), first assessing the content validity of items for the instruments following a rigorous process. Through two cross-sectional samples (Study 1: Sample 1 N = 255, Sample 2 N = 260) and one longitudinal sample (Study 2: Sample 3 N = 118) of competitive athletes in the UK, we then examined factorial, convergent, discriminant, and concurrent validity and measurement invariance (Study 1), as well as internal consistency, and test-retest reliability (Study 2) of the two new scales. Results revealed robust construct validity and reliability of scores on the two instruments and suggested very good invariance when implementing the new scales to athletes from different sports and competitive levels and good invariance for cross-gender comparisons. The new scales fill a gap in the sport psychology literature and provide researchers and practitioners with robust psychometric instruments to examine new research questions and tackle issues relevant to athletes’ sport-specific fantasy proneness and perceptions of deflated reality. 相似文献

Research on national identity distinguishes between national glorification and attachment. We tested whether glorification and attachment differentially predicted support for military and diplomatic conflict resolution strategies (CRS) in response to international conflicts. Using data collected in seven countries (Australia, United States, United Kingdom, France, Germany, Israel, China; total N = 1784), we investigated whether glorification and attachment can be equivalently measured (using tests of measurement invariance) and whether their relationships with CRS were generalizable across countries. The results revealed metric, but not scalar, measurement invariance of the two-factor structure of national identification across six countries, excluding China. Among these six countries, glorification predicted more support for military CRS, whereas attachment predicted more support for diplomatic CRS. Our study is novel in scrutinizing the cross-cultural generalizability of the bi-dimensional model of national identification. Implications for studying national identification and intergroup conflict cross-culturally are discussed. 相似文献

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19. 相似文献

A reparameterization is formulated that yields estimates of scale-invariant parameters in recursive path models with latent variables, and (asymptotically) correct standard errors, without the use of constrained optimization. The method is based on the logical structure of the reticular action model. 相似文献

This study investigates the measurement equivalence of a Five Factor measure of personality between applicant and non-applicant samples. The Big Five Questionnaire-2 was administered in two samples: A group of volunteers (n = 903), who completed the test for research purposes, and a group applying for jobs, who completed the test during hiring procedures (n = 401). Multiple-group confirmatory factor analysis on item composites was conducted to test for the equivalence of factor covariance and mean structures of twenty facets of the Five Factors. Item-level analyses were carried out through analysis of variance to further examine the issue of measurement invariance. Findings suggested that personality facets have the same measurement unit across applicants and non-applicants, while a lack of equivalence was found in the origin of the scales. Similar results were found at the item-level. Implications for personality assessment are advanced and discussed. 相似文献
