Pearson's correlation is widely used to test for an association between two variables and also forms the basis of several multivariate statistical procedures including many latent variable models. Spearman's [rho] is a popular alternative. These procedures are compared with ranking the data and then applying the inverse normal transformation, or…

Most existing studies on the relationship between factor analysis (FA) and principal component analysis (PCA) focus on approximating the common factors by the first few components via the closeness between their loadings. Based on a setup in Bentler and de Leeuw (Psychometrika 76:461-470, 2011), this study examines the relationship between FA…

The association between maternal diabetes and risk of autism spectrum disorder in offspring was not completely consistent. We performed an updated and systematic review and meta-analysis with relevant studies published until 6 August 2020. We included 17 publications, describing 15 studies, including 1,751,537 participants. Exposure to maternal…

This study synthesizes quantitative research on the relationship between creativity and bilingualism. Extant literature underlines the role of developmental, cognitive, and socio-cultural factors to explain the nature of the relationship between creativity and bilingualism. While decades of research frequently indicate a positive link, contrary or…

Perfectionism research has progressively supported an identification of two related dimensions, referred to as perfectionistic strivings (PS) and perfectionistic concerns (PC). Examinations of learner experiences based on these two dimensions have routinely demonstrated differential influence on academic emotions and performances, examining the…

In chemical synthesis, obtaining product(s) with high purity is a crucial issue from both academic and industrial viewpoints. Higher purity of the product(s) means higher quality and a lower chemical production costs. Sometimes, purification and separation processes are very laborious and lead to significant impacts on the final price of the…

Among cognitive factors that can influence the endorsement of pseudoscientific beliefs, our study focuses on proneness to false memory generation. In this preregistered study, we presented 170 fluent English speakers residing in the USA with a misinformation task aimed at generating false memories. In this task, they first completed an event…

Cyber victimization is a growing global concern, impacting both the physical and mental well-being of individuals.

For this reason, their development is also contemplated as among the main objectives of science education. However, in the literature about the two types of thinking in the context of science…

Gelotophobia (fear of being laughed at) is an under-researched phenomenon in autistic people, yet can have a significant impact on autistic people's quality of life. A narrative review was undertaken to explore if gelotophobia and being autistic are related and what is currently known in the academic literature regarding gelotophilia (joy of being…

Motor stereotypy is a type of repetitive motor behavior frequently occurring in autism spectrum disorder (ASD). Individuals with maladaptive daydreaming (MD) report repetitive motor behavior associated with addictive and immersive daydreaming. Many autistic self-advocates report symptoms of MD. Motor stereotypy in ASD is associated with lower…

Learning analytics (LA), like much of machine learning, assumes the training and test datasets come from the same distribution. Therefore, LA models built on past observations are (implicitly) expected to work well for future observations. However, this assumption does not always hold in practice because the dataset may drift. Recently,…

Individuals and organizations frequently tout creative ideas as a desirable goal, and yet, creative ideas are frequently rejected. Creativity researchers have often suggested that creative ideas are rejected because they are perceived as riskier due to their inherent novelty or originality. Although this assumption is prevalent, we are unaware of…

We present a model of endogenous schooling and earnings to isolate the causal effect of parents' education on children's education and earnings outcomes. The model suggests that parents' education is positively related to children's earnings, but its relationship with children's education is ambiguous. Identification is achieved by comparing the…

The relationship between confidence and accuracy has long been an important and controversial topic within the field of human memory. In a recent review article, Schwartz (2024). "Inferential theories of retrospective confidence." Metacognition & Learning.) competently summarized some of the key empirical findings on this issue and…
