Validation of data collection instruments is a necessary step in all research and should be regarded as an integral component in every stage of the research process; however, the validation process is often not accounted for in detail in published studies. The purpose of this paper is to describe the development and validation of the Ungspråk…

In this paper, the association between bilingualism and creativity is investigated. In the first part, the results of a literature review are reported. Previous research predominantly found that bilinguals outperform monolinguals on creativity tasks, which was explained by bilinguals' enhanced executive functioning compared to monolinguals, and…

Research into the role of individual difference (ID) factors in the process of second and foreign language (L2) learning and teaching has been one of the most robust lines of inquiry in the field of second language acquisition (SLA; Dörnyei & Ryan, 2015; Griffiths & Soruç, 2020; Pawlak & Kruk, 2022).

Dabrowski's theory of positive disintegration has been associated with the psychology of giftedness for four decades, and Sal Mendaglio has significantly contributed to the thoughtful understanding of the theory throughout those 40 years. In this interview, Mendaglio discusses the relationship between the theory of positive disintegration and the…

Bourdieu's thinking tool of habitus is helpful for understanding the relationship between the individual and the environment. Although habitus is often seen as something that an individual acquires in early life and is 'stuck with,' there are opportunities to develop a secondary habitus. Explicit pedagogy is a key factor in assisting individuals…

The misuse of prescription medications has emerged as a national public health concern. Epidemiological studies suggest that college students are at an elevated risk to engage in nonmedical use of several medications, including stimulants and central nervous system depressants. Teachers can easily integrate material related to the nonmedical use…

In exploratory or unrestricted factor analysis, all factor loadings are free to be estimated. In oblique solutions, the correlations between common factors are free to be estimated as well. The purpose of this article is to show how likelihood-based confidence intervals can be obtained for rotated factor loadings and factor correlations, by…

Exploratory factor analysis (EFA) is often conducted with ordinal data (e.g., items with 5-point responses) in the social and behavioral sciences. These ordinal variables are often treated as if they were continuous in practice. An alternative strategy is to assume that a normally distributed continuous variable underlies each ordinal variable.…
