Meta‐analysis is a statistical tool for estimating the mean and variance of underlying population effects from a collection of empirical studies addressing ostensibly the same research question. Meta‐analysis has become an increasing popular and valuable tool in psychological research, and major review articles typically employ these methods. This article describes the process of conducting meta‐analysis: selecting articles, developing inclusion criteria, calculating effect sizes, conducting the actual analysis (including information on how to do the analysis on popular computer packages such as IBM SPSS and R) and estimating the effects of publication bias. Guidance is also given on how to write up a meta‐analysis. 相似文献
Background. Recent studies have investigated the causal attributions for difficult pupil behaviour made by teachers, pupils, and parents but none have investigated the temporal stability or predictive validity of these attributions. Aims. This study examines the causal attributions made for difficult classroom behaviour by students on two occasions 30 months apart. The longitudinal stability of these attributions is considered as is the predictive validity of the first set of attributions in relation to teachers' later judgments about individual students' behaviour. Sample. Two hundred and seventeen secondary school age pupils (114 males, 103 females) provided data on the two occasions. Teachers also rated each student's behaviour at the two times. Method. A questionnaire listing 63 possible causes of classroom misbehaviour was delivered to pupils firstly when they were in Year 7 (aged 11–12) and then again, 30 months later. Responses were analysed through exploratory factor analysis (EFA). Additionally, teachers were asked to rate the standard of behaviour of each of the students on the two occasions. Results. EFA of the Years 7 and 10 data indicated that pupils' attributions yielded broadly similar five‐factor models with the perceived relative importance of these factors remaining the same. Analysis also revealed a predictive relationship between pupils' attributions regarding the factor named culture of misbehaviour in Year 7, and teachers' judgments of their standard of behaviour in Year 10. Conclusion. The present study suggests that young adolescents' causal attributions for difficult classroom behaviour remain stable over time and are predictive of teachers' later judgments about their behaviour. 相似文献
The present paper shows that the usual factor analytic structured data dispersion matrix Λ Ψ Λ′ + Δ can readily arise from
a set of scores y = Λ η + ε, where the “common” (η) and “unique” (ε) factors have nonzero covariance: Γ = Covε,η) ≠ 0. Implications of this
finding are discussed for the indeterminacy of factor scores, and for the issue of invariance of factor analytic covariance
models. The size of the problem is explored with numerical examples.

There is a strong pull to the idea that there is some metaphysically interesting distinction between the fully real, objective, observer‐independent qualities of things as they are in themselves, and the less‐than‐fully‐real, subjective, observer‐dependent qualities of things as they are for us. Call this (putative) distinction the primary/secondary quality distinction. The distinction between primary and secondary qualities is philosophically interesting because it is (a) often quite attractive to draw such a distinction, and (b) incredibly hard to spell it out in any kind of satisfying and sensible way. I attempt such a spelling‐out after first trying to pin down in more detail what we want from the primary/secondary quality distinction, and saying a bit about why that is such a hard thing to get. 相似文献

Lesbian, gay, bisexual, and queer (LGBQ) students are a substantial minority group within U.S. elementary, middle, and high schools. Many LGBQ students face harassment and discrimination, which can contribute to educational and psychological problems. Teachers play key roles in students’ school experiences, and their attitudes about homosexuality can influence their behavior toward LGBQ students. The purpose of this study was to examine the prevalence of teachers’ positive and negative LGBQ-related attitudes, potential changes in attitudes over time, and demographic and social variables that may be related to teachers’ attitudes. This study uses data from 305 pre-kindergarten through 12th grade teachers, collected in waves 2006–2014 of the General Social Survey. Results indicate that teachers’ attitudes toward homosexuality have become more favorable over time; however, many teachers still hold negative attitudes. Just under half of teachers exhibited at least one negative LGBQ-related attitude. Age, political conservativeness, religious attendance, and carryover of religious beliefs were significantly associated with negative LGBQ attitudes. Teachers with a fundamentalist religious orientation tended to have more negative attitudes about homosexuality than teachers with more progressive religious orientations. Negative attitudes were more often found among teachers of color, compared to White teachers, and teachers in the South, Midwest, and Mountain regions tended toward more negative attitudes than teachers in the Northeast and Pacific regions. Teachers have an ethical responsibility to see that all students, regardless of sexual orientation, receive a quality education. Education and training are needed to address problematic attitudes that may negatively affect LGBQ students.
ABSTRACT— Contemporary theories of learning typically assume that learning is driven by prediction errors—in other words, that we learn more when our predictions turn out to be incorrect than we do when our predictions are correct. Results from the recording of electrical brain activity suggest one mechanism by which this might happen; we seem to direct visual attention toward the likely causes of previous prediction errors. This can happen very rapidly—within less than 200 milliseconds of the error-causing object being presented. It is tempting to infer that if learning is driven by prediction errors, then little can be learned in the absence of feedback. Such a conclusion is unwarranted. In fact, the substantial learning that is sometimes the result of simple exposure to objects can also be explained by processes of directing attention toward the likely causes of previous prediction errors. 相似文献
Anxiety disorders are known to run in families [Turner, S. M., Beidel, D. C., & Costello, A. (1987). Psychopathology in the offspring of anxiety disorder patients. Journal of Consulting and Clinical Psychology, 55(2), 229–235] and environmental factors may largely account for the concordance between parental and child anxieties. Cognitive psychology models emphasise the importance of interpretive biases towards threat in the maintenance of anxiety and it is well established that anxious adults and children display similar interpretive biases and that these biases in anxious parents and their children are correlated. This raises the question of whether anxious cognitions/cognitive style may be transmitted from parent to child. We propose that this is more likely if anxious parents demonstrate interpretive biases not only about potential threats in their own environment but also about potential threats in their child's environment. Forty parents completed a recognition memory measure of interpretation bias adapted from Eysenck, Mogg, May, Richards, and Mathews (1991) [Bias in interpretation of ambiguous sentences related to threat in anxiety. Journal of Abnormal Psychology, 100(2), 144–150] to measure biases in response to potentially threat provoking situations involving themselves and their child. The interpretive biases demonstrated by parents were similar across situations involving themselves and their children. As expected, parental interpretive biases were further modified by anxiety with higher levels of parental anxiety associated with more negative interpretive biases about situations in their own and their child's environment, although this association was significantly stronger for potentially threat provoking situations in their own environment. These results are consistent with parent's interpretive biases extending beyond their own environment into their child's environment, although future research should continue to consider the mechanisms by which anxious parents may transmit fear cognitions to their children. 相似文献
