The field of educational leadership has yet to develop a coherent knowledge base that reflects the global diversity of policies and practices. This disconnect -- for example between Asian and Western research, presents a major challenge, curtailing authentic knowledge production and transfer. Accordingly, a major objective for the field is the…

This study's aim is to measure the effect sizes of the quantitative studies that examined the effectiveness of brain-based learning on students' academic achievement and to examine with the meta-analytical method if there is a significant difference in effect in terms of the factors of education level, subject matter, sampling size, and the…

A recent meta-analysis of 164 terror management theory (TMT) papers indicated that mortality salience (MS) yields substantial effects (r = 0.35) on worldview and self-esteem-related dependent variables (B. L. Burke, A. Martens, & E. H. Faucher, 2010). This study reanalyzed the data to explore the researcher effects of TMT. By cluster-analyzing…

This meta-analysis addresses whether achievement goal researchers are using different labels for the same constructs or putting the same labels on different constructs. We systematically examined whether conceptual and methodological differences in the measurement of achievement goals moderated achievement goal intercorrelations and relationships…

Meta-analytic procedures were used to test the effects of violent video games on aggressive behavior, aggressive cognition, aggressive affect, physiological arousal, empathy/desensitization, and prosocial behavior. Unique features of this meta-analytic review include (a) more restrictive methodological quality inclusion criteria than in past…

Used meta-analytic procedures from 51 studies worldwide to assess the reliability of two self-report measures (Parent Acceptance-Rejection Questionnaire and Personality Assessment Questionnaire) which test the transcultural association between perceived parental acceptance/rejection and psychological adjustment. Both were found reliable for use…

Reports a meta-analysis of published cross-cultural self-construal research. Notes that the results across studies suggests that the evidence for the predicted cultural differences is weak, inconsistent, or nonexistent. Concludes that catastrophic validity problems exist in research involving the use of self-construal scales in cross-cultural…

Disagrees with Levine et al.'s conclusion (published in this issue, see CS 764 297) that the three self construal scales currently in use have "severe" or "fatal" flaws. Argues that the results of Levine et al.'s meta-analysis and priming studies do not raise problems with the validity of self construal scales. Concludes that the two-dimensional…

Addresses each of the three main areas of Levine et al.'s (see this issue, CS 764 297) validity testing: mean differences in self-construals between Asians and Westerners and within individuals; priming experiments; and factor analysis of self-construal scales. Suggests that Levine et al.'s conclusions on crucial aspects of validity are untenable.…

Offers a critical rejoinder in the discussion concerning the viability of self-construal scales. Disputes the arguments to the contrary offered by Gudykunst and Lee and Kim and Raja (see this issue, CS 764 298-299). Sees the potential utility in the self-construal construction, but the three primary scales fail to meet reasonable and accepted…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…
