Sleeping in a Creative Dream-Land: A Duo of Meta-Analyses on Sleep, Dream-Recall, and Creativity

This duo of meta-analyses explored relationships between creativity and sleep quality [Study 1], and creativity and dream recall [Study 2]. Studies on these topics noted personality influences in both creativity and sleep quality, as well as dream recall. Studies also identified potential connections between creativity, sleep, and dreaming by investigating the stage of sleep from which creative thinking could emerge. Twenty studies were eligible to code and analyze in Study 1 and 16 in Study 2. Analyses using two-level multivariate analyses showed a small and positive correlation between creativity and sleep (r = .147, 95% CI = [0.033, 0.257]), p = .012 [Study 1] as well as creativity and dream recall (r = 0.173, 95% CI = [0.089, 0.257]), p = .001) [Study 2]. Both Study 1 and Study 2 tested moderator variables via a meta-regression. Moderators were identified based on the nature of assessments used, sample characteristics, and study characteristics. Study 1 results indicated that the relationship between sleep and creativity was higher when creativity test modality was verbal than figural. Study 2 also found that test modality was a significant moderator, and conversely, the relationship was larger when creativity was measured by figural tests compared to the verbal …

Lasso Regularization for DIF Detection in Graded Response Models

Previous research has tested the lasso method for DIF detection in dichotomous items, but limited research is available on this technique for polytomous items. This simulation study compares the lasso method to hybrid ordinal logistic regression to test performance in terms of TP and FP rates when considering sample size, test length, number of response categories, group balance, DIF proportion, and DIF magnitude. Results showed better Type I error control with the lasso, with smaller sample sizes, unbalanced groups, and weak DIF. The lasso also exhibited more stable Type I error control when DIF was weak, and groups were unbalanced. Lastly, low DIF proportion contributed to better Type I error control and higher TP rates with both methods.

Parenting Highly and Profoundly Gifted Children: Perspectives on Competence, Belonging, and Support within a Sociocultural Context

Limited research exists regarding the experiences and perspectives of parents of highly and profoundly gifted children. The purpose of this qualitative study was to investigate the experiences and perspectives of parents of highly and profoundly gifted children in developmental and cultural contexts. Semi-structured interviews were followed by thematic analysis regarding parental efficacy and parents' perceived support in parenting and educational communities to provide rich insights and to illuminate the voices of parents. In seeking academic and/or social emotional support, parents join groups designed to connect parents with experts in the field of gifted education and parent advocates of gifted children. A purposive sample was selected from parents who are members of networks and organizations serving profoundly gifted students. A self-report survey was distributed to parents enrolled in networks and/or organizations serving gifted students and parents of gifted students (e.g., SENG, Davidson Institute). Participant interviews were transcribed and qualitatively analyzed using thematic analysis. A qualitative descriptive analysis identified areas in which parents of highly and profoundly gifted children express the need for support within developmental and cultural contexts. Implications from the study aim to bring attention to the lived experiences of these parents to inform educators, counselors, and communities of parents' …
