Meta-analyses often include studies that report multiple effect sizes based on a common pool of subjects or that report effect sizes from several samples that were treated with very similar research protocols. The inclusion of such studies introduces dependence among the effect size estimates. When the number of studies is large, robust variance…

College students and military populations can have many similar yet very different characteristics related to their financial lives. Using social learning theory, this study examined factors that influence financial behavior outcomes of both populations using primary data. Findings indicate past behaviors and some personal factors play a…

Two experiments examined the extent to which erroneous recall blocks veridical recall using, as a vehicle for study, the disruptive impact of distractors that are semantically similar to a list of words presented for free recall. Instructing participants to avoid erroneous recall of to-be-ignored spoken distractors attenuated their recall but this…

This research examined the personality trait and personality disorder correlates of creative potential, as assessed by a divergent thinking (DT) test. Over 4,000 adult managers attending an assessment center completed a battery of tests including a "bright side," normal personality trait measures (NEO Personality Inventory-Revised, or…

Although previous research suggests that mood can influence creativity, the controversy about the effects of positive and negative moods has raged for years. This study investigated how the relationship between induced mood and creativity is moderated by dispositional and situational autonomy. It contrasted the different moderating effects of the…

Previous studies have established that higher test anxiety (TA) is related to achievement goals with an avoidance valence. However, comprehensive empirical examination of relations between the recently proposed 3 × 2 model of achievement goals (self, task, and other-referenced goals along an approach-avoidance dimension) and test anxiety has yet…

In the present study, equivalence-based instruction was used to teach 2 4-member classes representing high and low statistical variability to 10 college students. Computerized equivalence-based instruction with multiple-exemplar training was used to teach the classes. A pretest-training-posttest design evaluated performances on both computer-based…

Online purposive samples have unknown biases and may not strictly be used to make inferences about wider populations, yet such inferences continue to occur. We compared the demographic and drug use characteristics of Australian ecstasy users from a probability (National Drug Strategy Household Survey, n = 726) and purposive sample (online survey…

This article looks into the processes and outcomes of setting up and maintaining a probability-based longitudinal online survey, which is recruited face-to-face and representative of both the online and the offline population aged 16-75 in Germany. This German Internet Panel studies political and economic attitudes and reform preferences through…

Most intergenerational social mobility studies are based upon retrospective data, in which samples of individuals report socioeconomic information about their parents, an approach that provides representative data for offspring but not the parental generation. When available, prospective data on intergenerational mobility, which are based on a…

Calendar instruments incorporate aided recall techniques such as temporal landmarks and visual time lines that aim to reduce response error in retrospective surveys. Those calendar instruments have been used extensively in off-line research (e.g., computer-aided telephone interviews, computer assisted personal interviewing, and paper and pen…

Based on survey data from 14 representative universities in Jiangsu Province, logistic regression is used to analyze the impact of family capital on the quantity and quality of individuals obtaining higher education. The study found that on the whole, family capital has a clearly positive promoting role in the quantity and quality of higher…

This study assesses how scientists think about science communication training based on the argument that such training represents an important tool in improving the quality of interactions between scientists and the public. It specifically focuses on training related to five goals, including views about training to make science messages…

Recently, Tunmer and Chapman provided an alternative model of how decoding and listening comprehension affect reading comprehension that challenges the simple view of reading. They questioned the simple view's fundamental assumption that oral language comprehension and decoding make independent contributions to reading comprehension by arguing…

Family educational involvement has been identified as a particularly beneficial practice for the achievement and behavioral outcomes of all students, including ethnic-minority students from families who have low levels of income, education, and English language proficiency. Despite the associated benefits, however, not all families are involved in…
