The current study used archival data to evaluate the fit of six latent variable models, originally generated by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395406. [CSA][Taylor &; Francis Online], [Web of Science ®] [Google Scholar], for the California Verbal Learning Test-Children's Version (CVLT-C; Delis, Kramer, Kaplan, &; Ober, 1994 Delis, D. C., Kramer, J. H., Kaplan, E. and Ober, B. A. 1994. California Verbal Learning Test—Children's Version, San Antonio, TX: Psychological Corporation.  [Google Scholar]) in a large (N = 289) sample of pediatric epilepsy cases presenting at three tertiary treatment centers. Using confirmatory factor analysis, we found that a model including factors of Attention Span, Learning Efficiency, Free Delayed Recall, Cued Delayed Recall, and Inaccurate Recall demonstrated the best relative fit for our data. These findings are consistent with those reported by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395406. [CSA][Taylor &; Francis Online], [Web of Science ®] [Google Scholar] in his reanalysis of the CVLT-C standardization sample data, supporting the validity of this factorial model in pediatric epilepsy populations.  相似文献

There are currently two computational accounts of how the time to read pseudohomophones (like BRANE) and their nonword controls (like FRANE) varies with changes in context. In Reynolds and Besner's (2005) account, readers vary the breadth of lexical activation in response to changes in context. A competing account proposed by Kwantes and Marmurek (2007 Kwantes, P. and Marmurek, H. 2007. Controlling lexical contributions to the reading of pseudohomophones. Psychonomic Bulletin & Review, 14: 373378. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and independently by Perry, Ziegler, and Zorzi (2007 Perry, C., Ziegler, J. C. and Zorzi, M. 2007. Nested incremental modeling in the development of computational theories: The CDP+ model of reading aloud. Psychological Review, 114: 273315. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) has readers varying their response criterion in response to changes in context. The present work adjudicates between these two accounts by examining how the effect of neighbourhood density changes as a function of list context when reading pseudohomophones aloud. The results of an experiment and simulations from a leading computational model support the lexical breadth account, but are inconsistent with the response criterion account.  相似文献

Second-order latent growth curve models (S. C. Duncan &; Duncan, 1996 Duncan, S. C. and Duncan, T. E. 1996. A multivariate growth curve analysis of adolescent substance use.. Structural Equation Modeling, 3: 323347. [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]; McArdle, 1988 McArdle, J. J. 1988. “Dynamic but structural equation modeling of repeated measures data.”. In Handbook of multivariate experimental psychology, , 2nd ed. Edited by: Cattell, R. B. and Nesselroade, J. 564614. New York: Plenum.. [Crossref] [Google Scholar]) can be used to study group differences in change in latent constructs. We give exact formulas for the covariance matrix of the parameter estimates and an algebraic expression for the estimation of slope differences. Formulas for calculations of the required sample size are presented, illustrated, and discussed. They are checked by Monte Carlo simulations in Mplus and also by Satorra and Saris's (1985) Satorra, A. and Saris, W. E. 1985. The power of the likelihood ratio test in covariance structure analysis.. Psychometrika, 50: 8390. [Crossref], [Web of Science ®] [Google Scholar] power approximation techniques for small and medium effect sizes (Cohen, 1988 Cohen, J. 1988. Statistical power analysis for the behavioral sciences. Hillsdale, NJ: Erlbaum..  [Google Scholar]). Results are similar across methods. Not surprisingly, sample sizes decrease with effect sizes, indicator reliabilities, number of indicators, frequency of observation, and duration of study. The relative importance of these factors is also discussed, alone and in combination. The use of the sample size formula is illustrated using a modification of empirical results from Stoel, Peetsma, and Roeleveld (2003) Stoel, R. D., Peetsma, T. T. and Roeleveld, J. 2003. Relations between the development of school investment, self-confidence, and language achievement in elementary education: A multivariate latent growth curve approach..

This study addresses the reasons for the anti-Muslim sentiments held by some South Koreans. The research was motivated by the fact that, although previous studies have paid much attention to this issue in Western regions, such as Europe and the USA, little research has examined the perceptions of Muslims held by people in Asian countries. This empirical study of the nature of anti-Muslim sentiment in South Korea was aided by two theoretical frameworks that relate prejudice to (i) deprivation and (ii) religion. This study analysed data taken from the ‘International Social Survey Programme (ISSP) Topical Module: Religion (2008)’ [ISSP Research Group 2012 ISSP Research Group. 2012. “International Social Survey Programme: Religion III – ISSP 2008.” GESIS Data Archive, Cologne. ZA4950 Data file Version 2.2.0. doi:10.4232/1.11334 Study No. ZA4950.[Crossref] [Google Scholar]. ‘International Social Survey Programme: Religion III – ISSP 2008.’ GESIS Data Archive, Cologne. ZA4950 Data file Version 2.2.0, doi:10.4232/1.11334 Study No. ZA4950]. The results showed that deprivation did not significantly influence South Korean attitudes toward Muslims, whereas prejudice toward Muslims among South Koreans included a distinctly religious component.  相似文献

Studies in the Proteus Effect (N. Yee & J. Bailenson, 2007 Yee, N. and Bailenson, J. 2007. The proteus effect: The effect of transformed self-representation on behavior. Human Communication Research, 33: 271290. [Crossref], [Web of Science ®] [Google Scholar]) have shown that the appearance of avatars (i.e., digital representations of ourselves) can lead to behavioral changes in users. For example, participants in attractive avatars became friendlier to confederate strangers than participants in unattractive avatars. While the Proteus Effect is premised on self-perception theory (D. Bem, 1972 Bem, D. 1972. “Self-perception theory.”. In Advances in experimental social psychology Edited by: Berkowitz, L. Vol. 6, New York: Academic Press. [Crossref] [Google Scholar])—the notion that we infer our own attitudes by observing ourselves as if from a third party—it is also possible that the previous findings were caused by priming (i.e., behavioral assimilation; J. Bargh, M. Chen, & L. Burrows, 1996 Bargh, J., Chen, M. and Burrows, L. 1996. The automaticity of social behaviour: Direct effects of trait concept and stereotype activation on action. Journal of Personality and Social Psychology, 71: 230244. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). In our study, we used immersive virtual environment technology to experimentally tease apart embodiment from perception of the same visual stimulus. Our results showed that embodiment produced significantly larger behavioral changes than mere observation of the same visual stimuli. These findings support the claim that our avatars provide a unique lever to behavioral change; however, more work is needed to pin down the exact mechanism behind the effect.  相似文献

Valedictory     
Contingentism, generally contrasted with law necessitarianism, is the view that the laws of nature are contingent. It is often coupled with the claim that their contingency is knowable a priori. This paper considers Bird's [2001 Bird, Alexander 2001. Necessarily, Salt Dissolves In Water, Analysis 61/4: 26774.[Crossref], [Web of Science ®] [Google Scholar], 2002 Bird, Alexander 2002. On Whether Some Laws Are Necessary, Analysis 62/3: 25770.[Crossref], [Web of Science ®] [Google Scholar], 2005 Bird, Alexander 2005. Unexpected A Posteriori Necessary Laws of Nature, Australasian Journal of Philosophy 83/4: 53348.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar], 2007 Bird, Alexander 2007. Nature's Metaphysics: Laws and Properties, Oxford: Clarendon Press.[Crossref] [Google Scholar]] arguments for the thesis that, necessarily, salt dissolves in water; and it defends his view against Beebee's [2001] and Psillos's [2002 Psillos, Stathis 2002. Salt Does Dissolve In Water, But Not Necessarily, Analysis 62/3: 2557.[Crossref], [Web of Science ®] [Google Scholar]] contingentist objections. A new contingentist objection is offered and several reasons for scepticism about its success are raised. It is concluded that certain higher-level laws describing the behaviours of molecular compounds may be necessary due to their dependence on underlying physical laws, and that the modal status of laws of nature cannot be determined a priori, as the structural features of the substances and properties they govern must first be investigated.  相似文献

Maxwell, Cole, and Mitchell (2011) extended the work of Maxwell and Cole (2007) Maxwell, S. E. and Cole, D. A. 2007. Bias in cross-sectional analyses of longitudinal mediation. Psychological Methods, 12: 2344. [Crossref], [PubMed], [Web of Science ®] [Google Scholar], which raised important questions about whether mediation analyses based on cross-sectional data can shed light on longitudinal mediation process. The latest article considers longitudinal processes that can only be partially explained by an intervening variable, and Maxwell et al. showed that the same general conclusions are obtained, namely that analyses of cross-sectional data will not reveal the longitudinal mediation process. While applauding the advances of the target article, this comment encourages the detailed exploration of alternate causal models in psychology beyond the autoregressive model considered by Maxwell et al. When inferences based on cross-sectional analyses are compared to alternate models, different patterns of bias are likely to be observed. I illustrate how different models of the causal process can be derived using examples from research on psychopathology.  相似文献

Determining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990 Atran , S. (1990). Cognitive foundations of natural history: Towards an anthropology of science . New York , NY : Cambridge University Press. [Google Scholar]; Gil-White, 2001 Gil-White , F. J. ( 2001 ). Are ethnic groups biological ‘species’ to the human brain? Essentialism in our cognition of some social categories . Current Anthropology , 42 , 515554 .[Crossref], [Web of Science ®] [Google Scholar]), whereas others point to the role of noun labels as more general promoters of kind-based reasoning (Bigler &; Liben, 2007 Bigler , R. S. , &; Liben , L. S. ( 2007 ). Developmental intergroup theory: Explaining and reducing children's social stereotyping and prejudice . Current Directions in Psychological Science , 16 , 162166 .[Crossref], [Web of Science ®] [Google Scholar]; Gelman, 2003 Gelman , S. A. ( 2003 ). The essential child: Origins of essentialism in everyday thought . New York , NY : Oxford University Press .[Crossref] [Google Scholar]). A novel groups procedure was employed to examine the independent effects of noun labels and visual cues on social categorization. Experiment 1 demonstrated that in the absence of a visual cue, a noun label supported social categorization among 4-year-olds and 7-year-olds. Experiments 2 and 3 demonstrated that children and adults fail to differentiate between intrinsic and nonintrinsic visual cues to category membership, suggesting that this distinction is not central to the acquisition of social category concepts. Experiments 2 and 3 also showed that in the absence of a shared noun label, visual cues were not sufficient for younger children to form social categories. Experiment 4 ruled out a potential demand characteristic in the previous experiments. Together, these results reveal the primacy of verbal labels over visual cues for social categorization in young children and suggest a developmental change between ages 4 and 7 in the ability to construct new representations of social category concepts.  相似文献

Maxwell and Cole (2007) Maxwell, S. E. and Cole, D. A. 2007. Bias in cross-sectional analyses of longitudinal mediation. Psychological Methods, 12: 2344. [Crossref], [PubMed], [Web of Science ®] [Google Scholar] showed that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters in the special case of complete mediation. However, their results did not apply to the more typical case of partial mediation. We extend their previous work by showing that substantial bias can also occur with partial mediation. In particular, cross-sectional analyses can imply the existence of a substantial indirect effect even when the true longitudinal indirect effect is zero. Thus, a variable that is found to be a strong mediator in a cross-sectional analysis may not be a mediator at all in a longitudinal analysis. In addition, we show that very different combinations of longitudinal parameter values can lead to essentially identical cross-sectional correlations, raising serious questions about the interpretability of cross-sectional mediation data. More generally, researchers are encouraged to consider a wide variety of possible mediation models beyond simple cross-sectional models, including but not restricted to autoregressive models of change.  相似文献

The Open Science Collaboration’s 2015 Open Science Collaboration. (2015). Estimating the reproducibility of psychological science. Science, 349, aac4716. doi:10.1126/science.aac4716[Crossref], [PubMed], [Web of Science ®] [Google Scholar] report suggests that replication effect sizes in psychology are modest. However, closer inspection reveals serious problems. When plotting replication effects are against original effects, the regression trap is lurking: Expecting replication effects to be equally strong as original effects is logically unwarranted; they are inevitably subject to regressive shrinkage. To control for regression, the reliability of original and replication studies must be taken into account. Further problems arise from missing manipulation checks and sampling biases. Our critical comment highlights the need for replication science to live up to the same methodological scrutiny as other research.  相似文献

During the past three decades, researchers interested in emotions and cognition have attempted to understand the relationship that affect and emotions have with cognitive outcomes such as judgement and decision-making. Recent research has revealed the importance of examining more discrete emotions, showing that same-valence emotions (e.g., anger and fear) differentially impact judgement and decision-making outcomes. Narrative reviews of the literature (Lerner & Tiedens, 2006 Lerner, J. S. and Tiedens, L. Z. 2006. Portrait of the angry decision maker: How appraisal tendencies shape anger's influence on cognition. Journal of Behavioral Decision-Making, 19: 115137. [Crossref], [Web of Science ®] [Google Scholar]; Pham, 2007 Pham, M. T. 2007. Emotion and rationality: A critical review and interpretation of empirical evidence. Review of General Psychology, 11(2): 155178. [Crossref], [Web of Science ®] [Google Scholar]) have identified some under-researched topics, but provide a limited synthesis of findings. The purpose of this study was to review the research examining the influence of discrete emotions on judgement and decision-making outcomes and provide an assessment of the observed effects using a meta-analytic approach. Results, overall, show that discrete emotions have moderate to large effects on judgement and decision-making outcomes. However, moderator analyses revealed differential effects for study-design characteristics and emotion-manipulation characteristics by emotion type. Implications are discussed.  相似文献

ABSTRACT

Recent research has suggested that age-related positivity effects are eliminated under conditions of dual-task load (Knight et al., 2007 Knight, M., Seymour, T. L., Gaunt, J. T., Baker, C., Nesmith, K. and Mather, M. 2007. Aging and goal directed emotional attention: Distraction reverses emotional biases. Emotion, 7: 705714. [Crossref], [PubMed], [Web of Science ®] [Google Scholar], Emotion, 7, 705; Mather & Knight, 2005 Mather, M. and Knight, M. 2005. Goal directed memory: The role of cognitive control in older adults' emotional memory. Psychology and Aging, 20: 554570. [PubMed], [Web of Science ®] [Google Scholar], Psychology and Aging, 20, 554), because the cognitive control resources necessary to enact such preferences are not available when individuals are distracted by competing information. We further examined how older adults' emotional information processing preferences are affected by distracting information by utilizing a within-subjects dual-task measure. Younger and older adults viewed a series of positive, negative, and neutral images both in conditions of full and divided attention. Fixation preferences to valenced images were assessed through eye tracking. Regardless of whether images were viewed in full or divided attention conditions, older adults demonstrated a preference in their fixation for positive and neutral in comparison to negative images. These results provide evidence that older adults' positive fixation preferences may not always necessitate full, cognitive control.  相似文献

Although the proportion of women who patronize sexually oriented book-video-novelty stores appears to be growing, little is known about the phenomenon generally or about male–female differences. In the only studies of “female patrons of porn,” both Hefley (2007 Hefley , Kristen . 2007 . “Stigma Management of Male and Female Customers in to Non-Urban Adult Novelty Store.” Deviant Behavior 28 : 79109 .[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) and Berkowitz (2006 Berkowitz , Dana . 2006 . “Consuming Eroticism: Gender Performances and Presentations in Pornographic Establishments.” Journal of Contemporary Ethnography 35 : 583606 . [Google Scholar]) report that half of the customers that they observed entering two stores were women. Compared to men, women were less likely to enter alone. To further investigate this phenomenon, we observed customers entering 33 stores for 162 hours over a two-year period. Whereas the observations of Hefley (2007 Hefley , Kristen . 2007 . “Stigma Management of Male and Female Customers in to Non-Urban Adult Novelty Store.” Deviant Behavior 28 : 79109 .[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) and Berkowitz (2006 Berkowitz , Dana . 2006 . “Consuming Eroticism: Gender Performances and Presentations in Pornographic Establishments.” Journal of Contemporary Ethnography 35 : 583606 . [Google Scholar]) were limited to a few of the busiest hours, our observations span all seven weekdays and all hours. Seventeen percent of the patrons who entered the stores were women. This proportion varied over time and across the 33 stores. Women prefer to shop on weekend evenings in stores that provide visible security.  相似文献

Reading-specific and general color-shape cognitive flexibility were assessed in 68 first and second graders to examine: 1) the development of graphophonological-semantic cognitive flexibility (the ability to process concurrently phonological and semantic aspects of print) in comparison to color-shape cognitive flexibility, 2) the contribution of reading experience to graphophonological-semantic flexibility, and 3) the unique contribution of graphophonological-semantic flexibility to reading comprehension. Second graders scored significantly higher than first graders on both cognitive flexibility tasks; the general flexibility task was easier for all children than the graphophonological-semantic flexibility task; reading experience contributed uniquely to children's graphophonological-semantic flexibility; and graphophonological-semantic flexibility contributed significant, unique variance to children's reading comprehension, consistent with Cartwright's (2002 Cartwright , K. B. ( 2002 ). Cognitive development and reading: The relation of reading-specific multiple classification skill to reading comprehension in elementary school children . Journal of Educational Psychology , 94 , 5663 .[Crossref], [Web of Science ®] [Google Scholar]) work with second- to fourth-grade students and adults (2007 Cartwright , K. B. ( 2007 ).

Section 35(1)(c) of the Health Practitioner Regulation National Law Act (2009 Health Practitioner Regulation National Law Act of 2009. (Queensland).  [Google Scholar]) requires the newly formed Psychology Board of Australia (PsyBA) “to develop or approve standards, codes and guidelines.” In 2010 the PsyBA decided to initially adopt the Australian Psychological Society's (APS) Code of Ethics (2007 Australian Psychological Society. 2007. Code of ethics, Melbourne, , Australia: Author.  [Google Scholar]) and develop a new code in the future with the involvement of key stakeholders without deciding what the nature of this code will be. The PsyBA now has to decide exactly how it will proceed in future. My aim in this article is to examine the options available to the PsyBA by exploring the definition and function of codes; presenting a history of the APS Code; and considering approaches that had been followed in Europe, Israel, New Zealand, and South Africa.  相似文献

Recent case studies have demonstrated the potential benefits of Finn's Therapeutic Assessment (TA) model with families (e.g., Handler, 2007 Handler, L. 2007. “The use of therapeutic assessment with children and adolescents”. In The clinical assessment of children and adolescents: A practitioner's handbook, Edited by: Smith, S. R. and Handler, L. 5372. Mahwah, NJ: Lawrence Erlbaum Associates.  [Google Scholar]; Tharinger, Finn, Wilkinson, &; Schaber, 2007 Tharinger, D. J., Finn, S. E., Wilkinson, A. D. and Schaber, P. M. 2007. Therapeutic assessment with a child as a family intervention: A clinical and research case study. Psychology in the Schools, 44: 293309. [Crossref], [Web of Science ®] [Google Scholar]). This case study of a 6-year-old girl and her family follows the Therapeutic Assessment (TA) model, focusing on the specified goals of each session and how those goals were accomplished. In this article, we illustrate the flexibility afforded by the TA model to tailor an appropriate intervention for a specific family and also show that extensive experience with the TA model is not necessary for this approach to yield clinically significant results.  相似文献

Prior research indicates that dimensions of adolescent narcissism differ in their associations with indicators of positive and negative psychological functioning (e.g., Barry, Frick, Adler, &; Grafeman, 2007 Barry, C. T., Frick, P. J., Adler, K. K. and Grafeman, S. J. 2007. The predictive utility of narcissism among children and adolescents: Evidence for a distinction between adaptive and maladaptive narcissism. Journal of Child and Family Studies, 16: 508521. [Crossref] [Google Scholar]; Barry &; Wallace, 2010 Barry, C. T. and Wallace, M. T. 2010. Current considerations in the assessment of youth narcissism: Indicators of pathological and normative development. Journal of Psychopathology and Behavioral Assessment, 32: 479489. [Crossref], [Web of Science ®] [Google Scholar]). This study investigated correlates of 2 empirically derived factors of adolescent narcissism (i.e., pathological and nonpathological narcissism) from 2 measures thought to differ based on their inclusion of pathological versus nonpathological content. In a sample of 188 at-risk adolescents ages 16 to 18, pathological narcissism was associated with various indicators of maladjustment, including aggression, low self-esteem, internalizing problems, and poor perceived interpersonal relationships. On the other hand, nonpathological narcissism was positively associated with self-esteem and aggression but negatively associated with internalizing problems. The implications for the conceptualization of adolescent narcissism are discussed.  相似文献

Mentalization includes the ability to apprehend and reflect upon one's subjective state, as well as an appreciation of one's agency (Fonagy & Target, 2006 Fonagy, P. and Target, M. 2006. The mentalization-focused approach to self pathology. Journal of Personality Disorders, 20(6): 544576. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Masochism is a character pattern that is traditionally defined as pleasure in pain or suffering (Million, 1996 Million, T. M. 1996. Disorders of personality: DSM-IV and beyond , 2nd, New York: John Wiley and Sons.  [Google Scholar]). In some cases the etiology of this character pattern may mirror failures on the part of the caregiving surround that contribute to deficits in the ability to mentalize self (Fonagy, Gergely, & Target, 2007 Fonagy, P., Gergely, G. and Target, M. 2007. The parent-infant dyad and the construction of the subjective self. Journal of Child Psychology and Psychiatry, 48(3/4): 288328. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Benjamin, 1988 Benjamin, J. 1988. The bonds of love: Psychoanalysis, feminism, and the problem of domination, New York: Pantheon Books.  [Google Scholar]). When this occurs masochism may be more profitably understood as an inability to register pain, rather than pleasure in pain. A case example demonstrates that when a deficit in mentalization underlies masochistic functioning, treatment may include interventions aimed at helping the patient improve the ability to reflect upon his or her mental state, especially negative affect such as pain and anger, and connect to a sense of agency.  相似文献

The aim of this study was to examine coping with loneliness during early, middle, and late childhood, which is a highly neglected research issue. Children's perceptions of coping with loneliness and coping with real loneliness experiences in the past were investigated. Interviews were conducted with 180 second, fourth, and sixth graders from Athens, Greece. Qualitative analyses of children's responses were done on the basis of a recent conceptualization of coping with stress in childhood and adolescence (Skinner & Zimmer-Gembeck, 2007 Skinner, E. A. and Zimmer-Gembeck, M. J. 2007. The development of coping. Annual Review of Psychology, 58: 119144. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]), which was supported by the data. Statistically significant age and gender differences were found. Results are discussed from the viewpoint of the two literatures—coping and loneliness—that this study attempted to bring together, and suggestions for future research are made.  相似文献

In this paper, I use an autoethnographic sketch (Rambo, 2007 Rambo, C. (2007). Sketching as autoethnographic practice. Symbolic Interaction, 30(4), 531542. doi:10.1525/si.2007.30.4.531[Crossref], [Web of Science ®] [Google Scholar]) to offer a definition of trauma. This paper is broadly inspired by my research (Gloviczki, 2015 Gloviczki, P. J. (2015). Journalism and memorialization in the age of social media. New York, NY: Palgrave Macmillan.[Crossref] [Google Scholar]) using case study methods (Yin, 2003 Yin, R. K. (2003). Case study research: Design and methods (Vol. 3). Thousand Oaks, CA: Sage. [Google Scholar]) about online memorial groups. In pairing autoethnography and case study methods, I write to inspire a discussion about form, definition, and trauma. I also embrace the challenge of writing an entire scholarly paper within 140 characters, the standard length of a tweet on Twitter. I hope this approach opens fresh avenues for understanding research as well.  相似文献
