Previous research has investigated the Spatial Numerical Associations of Response Codes (SNARC) effect as a measure of spatial number coding in relation to mathematics (Cipora et al., 2020, https://doi-org.bibliotheek.ehb.be/10.1111/nyas.14355). An issue that arises if one wants to correlate mathematical performance with the SNARC effect, is how individual…

Individual differences in cognitive performance depend on age, skill, and type of task. Nonetheless, whether performance is measured with accuracy (ACC) or with the trade-off between responding speed and accuracy (SAT) could render subtle different relationships. Age and skill might associate more strongly with SAT performance in reasoning tasks,…

This research examined how spatial ability, sex, and cognitive styles associate with self-directed multimedia resource use (study 1) and learning outcomes (study 2). In study 1, three learning resource options were offered: two unimodal (text-only and labelled-picture) and one multimodal (picture-with-narration). Findings revealed that lower…

Intra-individual response time variability (IIRTV) during cognitive performance is increasingly recognized as an important indicator of attentional control (AC) and related brain region function. However, what determinants contribute to preschoolers' IIRTV received little attention. The present study explored the interaction of dopaminergic…

We set out to investigate whether interindividual differences in cognition affect the susceptibility to four forecasting biases: (a) optimism bias, (b) adding noise to forecasts, (c) presuming positive autocorrelation when series are independent, and (d) trend damping. All four biases were prevalent in the results, but we found no consistent…

Extraction of global structural regularities provides general 'gist' of our everyday visual environment as it does the gist of abnormality for medical experts reviewing medical images. We investigated whether naïve observers could learn this gist of medical abnormality. Fifteen participants completed nine adaptive training sessions viewing four…

"Variability" and "fractality," two key concepts in Complex Dynamic Systems Theory (CDST)--the former concerning changes and variations, and the latter concerning recursiveness and self-similarities--may seem contradictory at first glance. This forum piece attempts to elucidate how the two seemingly contradictory properties can…

Network analysis is a method used to explore the structural relationships between people or organizations, and more recently between psychological constructs. Network analysis is a novel technique that can be used to model psychological constructs that influence language learning as complex systems, with longitudinal data, or cross-sectional data.…

Objective: Food allergies are on the rise in the U.S. Factors associated with willingness and readiness to act in a food allergic emergency on a college campus are currently unknown. Participants: College students in one Catholic college enrolled during spring of 2017. Methods: A previously piloted survey was distributed by e-mail. Results: Four…

This study investigates how adolescents' daily prosocial behaviors to friends are related to diurnal cortisol using between- and within- subject analyses. Further, we examine whether role fulfillment (i.e., feeling like a good friend) moderates links between prosocial behaviors and cortisol. Ethnically diverse adolescents (N = 370; ages 11-18)…

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived…

The current study examined the psychometric properties and correlates of three measures assessing individual differences in mattering among people from Palestine assessed in January, 2024. This study uniquely considers mattering as a resource and feelings of not mattering as a risk factor among people experiencing traumatizing life circumstances.…

The spread of pseudoscience (PS) is a worrying problem worldwide. The study of pseudoscience beliefs and their associated predictors have been conducted in the context of isolated pseudoscience topics (e.g., complementary and alternative medicine). Here, we combined individual differences (IIDD) measures (e.g., personality traits, thinking styles)…

Current theories of loneliness posit that biases in social information processing play a key role in the development and maintenance of loneliness. However, this assumption has rarely been tested in longitudinal research in adolescence. The current study concentrated on two constructs associated with such biases, that is, fear of negative…

Based on the "Differential Susceptibility Theory," we examined whether the relationship between pubertal maturation and depressive symptoms can be moderated by individual differences in environmental sensitivity. The current article used the three-wave data collected from Japanese adolescents aged from 12 to 15 years (girls = 111,…
