This article examined the applicability of the interpersonal circumplex (IC) to the observable social behaviors of children during parent-child interactions. In Study 1, the observational ratings of behaviors of 117 children (mean age = 9.88 years) were examined. Randomization tests of hypothesized order relations found that these behaviors tended to occur in the circular pattern predicted by the IC. To illustrate the applicability of the IC to children's behavior, Study 2 (n = 94) used the circular structure of children's behavior to longitudinally examine children's participation in two risk behaviors, smoking cigarettes and consuming alcohol. Results indicated that children who behaved in an arrogant-calculating manner were at risk for smoking cigarettes and children who behaved in an assured-dominate manner were at risk for drinking alcohol 1 year later. Implications of these results are discussed in terms of their relevance for helping researchers better understand and categorize children's interpersonal behaviors. 相似文献

The purpose of this article was to propose and test an integrative model on the role of perfectionism, academic motivation, and psychological adjustment difficulties in undergraduate students. The model posits that self-oriented perfectionism facilitates self-determined academic motivation, whereas socially prescribed perfectionism enhances non-self-determined academic motivation. In turn, self-determined and non-self-determined academic motivations, respectively, lead to lower and higher levels of psychological adjustment difficulties. Results from two studies using structural equation modeling analyses provided support for the model. 相似文献

We recorded participants' eye movements while they read sentences containing verb-phrase coordination. Results showed evidence of immediate processing disruption when a reflexive pronoun embedded in the conjoined verb phrase mismatched the sentence subject. We argue that this result is incompatible with models of human parsing that employ only bottom-up parsing procedures, even when flexible constituency is employed. Models need to incorporate a mechanism similar to the adjoining operation in Tree-Adjoining Grammar, in which one structure is inserted into another. 相似文献

The aim of this study was to examine differences in responses to the Caregiver Strain Questionnaire (CGSQ) between African American and White caregivers of children with emotional and behavioral challenges. Significant item- and scale-level differences were detected across groups with African Americans consistently reporting less strain. We examined whether these differences were more likely due to nonequivalent measurement than to real differences in the experience of caregiver strain. Confirmatory factor analysis showed that the model fit the data well for both racial groups, but there were some differences in structural components. Internal consistency was equivalent across the groups. In an examination of criterion validity, regression analyses showed that African American caregivers experienced a slower rate of increase in objective caregiver strain at a given increase in child internalizing problems. No other race differences were found in the regression analyses. In general, we conclude that the CGSQ can be useful for detecting caregiver strain and identifying family support needs for both White and African American caregivers. Differences across groups in reports of caregiver strain, however, call for more research on racial differences in the impact on the family of caring for a child with emotional and behavioral disorders. 相似文献

Key ethical issues arise in association with the conduct of stem cell research by research institutions in the United States.
These ethical issues, summarized in detail, receive no adequate translation into federal laws or regulations, also described
in this article. U.S. Federal policy takes a passive approach to these ethical issues, translating them simply into limitations
on taxpayer funding, and foregoes scientific and ethical leadership while protecting intellectual property interests through
a laissez faire approach to stem cell patents and licenses. Those patents and licenses, far from being scientifically and
ethically neutral in effect, virtually prohibit commercially sponsored research that could otherwise be a realistic alternative
to the federal funding gap. The lack of federal funding and related data-sharing principles, combined with the effect of U.S.
patent policy, the lack of key agency guidance, and the proliferation of divergent state laws arising from the lack of Federal
leadership, significantly impede ethical stem cell research in the United States, without coherently supporting any consensus
ethical vision. Research institutions must themselves implement steps, described in the article, to integrate addressing ethical
review with the many legal compliance issues U.S. federal and state laws create.

Tracking multiple targets with multifocal attention 总被引:8,自引:0,他引:8
Attention allows us to monitor objects or regions of visual space and select information from them for report or storage. Classical theories of attention assumed a single focus of selection but many everyday activities, such as video games, navigating busy intersections, or watching over children at a swimming pool, require attention to multiple regions of interest. Laboratory tracking tasks have indeed demonstrated the ability to track four or more targets simultaneously. Although the mechanisms by which attention maintains contact with several targets are not yet established, recent studies have identified several characteristics of the tracking process, including properties defining a 'trackable' target, the maximum number of targets that can be tracked, and the hemifield independence of the tracking process. This research also has implications for computer vision, where there is a growing demand for multiple-object tracking. 相似文献

Three-year-old children were tested on three categorization tasks of increasing levels of abstraction (used with adult baboons in an earlier study): the first was a conceptual categorization task (food vs toys), the second a perceptual matching task (same vs different objects), and the third a relational matching task in which the children had to sort pairs according to whether or not the two items belonged to the same or different categories. The children were tested using two different procedures, the first a replication of the procedure used with the baboons (pulling one rope for a category or a relationship between two objects, and another rope for the other category or relationship), the second a task based upon childrens prior experiences with sorting objects (putting in the same box objects belonging to the same category or a pair of objects exemplifying the same relation). The children were able to solve the first task (conceptual categorization) when tested with the sorting into boxes procedure, and the second task (perceptual matching) when tested with both procedures. The children were able to master the third task (relational matching) only when the rules were clearly explained to them, but not when they could only watch sorting examples. In fact, the relational matching task without explanation requires analogy abilities that do not seem to be fully developed at 3 years of age. The discrepancies in performances between children tested with the two procedures, with the task explained or not, and the discrepancies observed between children and baboons are discussed in relation to differences between species and/or problem-solving strategies. 相似文献

This article recalls a classic scheme for categorizing attitude measures. One particular group of measures, those that rely on respondents' interpretations of partially structured stimuli, has virtually disappeared from attitude research. An attitude measure based on respondents' interpretation of partially structured stimuli is considered. Four studies employing such a measure demonstrate that it predicts unique variance in self-reported and actual behavior, beyond that predicted by explicit and contemporary implicit measures and regardless of whether the attitude object under consideration is wrought with social desirability concerns. Implications for conceptualizing attitude measurement and attitude-behavior relations are discussed. 相似文献

A number of lines of study suggest that word meanings are not always fully exploited in comprehension. In two experiments,
we used a text-change paradigm to study depth of semantic processing during reading. Participants were instructed to detect
words that changed across two consecutive presentations of short texts. The results suggest that the full details of word
meanings are not always incorporated into the interpretation and that the degree of semantic detail in the representation
is a function of linguistic focus. The results provide evidence for the idea that representations are only good enough for
the purpose at hand (Ferreira, Bailey, & Ferraro, 2002). 相似文献

The integration of continuous and discrete latent variable models: potential problems and promising opportunities 总被引:3,自引:0,他引:3
Structural equation mixture modeling (SEMM) integrates continuous and discrete latent variable models. Drawing on prior research on the relationships between continuous and discrete latent variable models, the authors identify 3 conditions that may lead to the estimation of spurious latent classes in SEMM: misspecification of the structural model, nonnormal continuous measures, and nonlinear relationships among observed and/or latent variables. When the objective of a SEMM analysis is the identification of latent classes, these conditions should be considered as alternative hypotheses and results should be interpreted cautiously. However, armed with greater knowledge about the estimation of SEMMs in practice, researchers can exploit the flexibility of the model to gain a fuller understanding of the phenomenon under study. 相似文献
