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…

Research on the question of creative benefit accompanying dyslexia has produced conflicting findings. In this meta-analysis, we determined summary effects of mean and variance differences in creativity between groups with and without dyslexia. Twenty studies were included (n = 770 individuals with dyslexia, n = 1,671 controls). A random-effects…

In this study, we analyzed data of heart rate and pulse amplitude collected by undergraduate students in a physiology lab course during and after the diving reflex. On average, heart rate was reduced 21% at 15 seconds and 29% at 30 seconds during diving. Pulse amplitude generally decreased but with greater individual variation. There is no…

Gender remains a key predictor of housework in modern society. However, previous studies have been relatively limited in their ability to adjudicate between possible mechanisms operating at the individual and social-interactional level that may cause this relationship. To address this gap, we employ a novel experimental design in which respondents…

The purpose of this study was to explore differences in time spent practicing and the practice strategies used by Chinese music majors according to university location, instrument played, and participant gender. A total of 154 participants who played string, woodwind, brass, and keyboard instruments, including 103 participants attending Chinese…

Interacting with native speakers in various types of virtual exchanges is becoming increasingly accessible for language learners and teachers around the world. The present study examined the experiences of beginning and intermediate level learners of Spanish in the United States as they interacted weekly with native Spanish speakers over the…

We study the effects of exposure to non-resident students on the outcomes of undergraduate in-state students during a period of high non-resident enrollment growth at the University of Missouri-Columbia. Our models leverage within-major, cross-time variation in nonresident exposure for identification. We find no evidence that increased exposure to…

While the use of musical parameters for emotional expression has been extensively studied, little is known about which specific musical parameters children at different ages are able to use for expressing specific emotions. We used a novel interface called Music Box that allows modification of musical parameters while music is being played in real…

To explore factors that may inform teaching and learning in STEM education, we investigate individual and situational factors influencing students' cooperative versus competitive responses in a classroom, extra-credit problem social dilemma in core biology and engineering courses. We were curious how our competitive academic environment coupled…

Speech is more difficult to understand when it is presented concurrently with a distractor speech stream. One source of this difficulty is that competing speech can act as an attentional lure, requiring listeners to exert attentional control to ensure that attention does not drift away from the target. Stronger attentional control may enable…

The primary purpose of this research is to investigate the vocabulary learning strategies employed by the undergraduate students of Sardar Bahadur Khan Women's University (SBKWU) and University of Balochistan (UOB), Quetta, Pakistan. A quantitative design was employed in this study to answer the two research questions of the present study. The…

This study set out to explore levels of religious affect (measured by the Francis Scale of Attitude toward Christianity) and personal affect (measured by the Oxford Happiness Questionnaire) among samples of Catholic students in the Republic of Ireland attending fifth- and sixth-year classes (N = 3015) and Catholic students in Northern Ireland…

The present study investigated the development of global and domain-specific self-representations in the transition from late childhood to early adolescence and tested whether gender, puberty, and school transition help explain individual differences in change. The study was based on three measurement occasions over 2 years and included 248…

Perceptual Learning Style theory (PLS) claims that the presentation of information in either a visual, auditory or kinaesthetic format will improve the learning of selected individuals due to the dominance of one or more modality in their information gathering. The modality dominance of six Western classical pianists in higher music education was…

The Cattell-Horn-Carroll (CHC) model is a comprehensive model of the major dimensions of individual differences that underlie performance on cognitive tests. Studies evaluating the generality of the CHC model across test batteries, age, gender, and culture were reviewed and found to be overwhelmingly supportive. However, less research is available…
