Longitudinal data analysis has been widely employed to examine between-individual differences in within-individual changes. One challenge of such analyses is that the rate-of-change is only available indirectly when change patterns are nonlinear with respect to time. Latent change score models (LCSMs), which can be employed to investigate the…

The study investigated the development of sources of self-efficacy in self-regulation in 9-12 year old (N = 317, primary school) students during one school year. We used latent growth curve modeling to determine (1) how the different sources of self-efficacy for self-regulation (i.e., mastery experience, vicarious experience, social persuasion,…

This phenomenological study investigates the lived experiences of Chinese international students during the initial outbreak of the COVID-19 pandemic. It aims to delve into how these individuals articulate their experiences during the pandemic, with a particular focus on how their geographical location influenced their experiences. To achieve…

In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed-accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual…

Whether or not styles are malleable is one of the major controversial issues in the field of intellectual styles. Taking thinking styles (one of the intellectual style constructs) as the theoretical basis, the present study aimed at clarifying the issue by examining the change of thinking styles over one year from multiple perspectives. Seven…

This study investigates how sensitively the current grit measure (Grit-S) is able to reflect the differences between individuals (i.e. item discrimination) and change within individuals (i.e. sensitivity to change of items) using longitudinal data. Data from the Korean Children and Youth Panel Study 2018 of elementary (fourth grade) and middle…

Longitudinal measurement enables the examination of behavioral or psychological change. One approach to examining longitudinal measurements is the use of latent growth curve modeling (LGCM). This approach affords the assessment of inter- and intraindividual change. Yet, this approach likely is underused in exercise science. The purpose of the…

The present study examined (1) intraindividual changes in the frequency of electronic nicotine delivery systems (ENDS) use across young adulthood, 18 to 30 years old, and (2) if depressive symptoms and sensation-seeking tendencies, independently and in interaction with one another, were associated with these changes. Data were from a longitudinal…

We leverage log data from an educational app and two-way text message records from over 3,500 students during the summers of 2019 and 2020, along with in-depth interviews in Spanish and English, to identify patterns of family engagement with educational technology. Based on the type and timing of technology use, we identify several distinct…

We leverage log data from an educational app and two-way text message records from over 3,500 students during the summers of 2019 and 2020 and in-depth interviews in Spanish and English to identify patterns of family engagement with educational technology. Based on the type and timing of technology use, we identify several distinct profiles of…

Food insecurity is highly prevalent among U.S. college students and is associated with poor eating behaviors, physical and mental health, and academic performance. The COVID-19 pandemic has caused immense income loss in the United States. Income loss is associated with increased food insecurity. Little is known about how college students' food…

We investigated children's (n = 120; 3- to 11-year-olds) and adults' (n = 18) reasoning about life-cycle changes in biological organisms by examining their endorsements of four different patterns of life- span changes. Participants were presented with two separate tasks: (a) judging possible adult versions of a juvenile animal and (b) judging…

This research paper seeks to determine learner autonomy level in relation to incidental vocabulary acquisition (IVA), out of the realization of both concepts as prominent factors in language learning in general, and English for Specific Purposes (ESP) in particular. The paper particularly aims at examining the influence of participants', medical…

Academic self-concept (ASC) is characterized by the dual nature of stability and change. That is, students strive for consistency in their self-concept but also receive achievement feedback that leads to changes in ASC. Only a few previous studies have scrutinized the stability of ASC. The STARTS model (Stable, AutoRegressive Trait, and State)…

Learning in the sciences is difficult for students from elementary school to university due to misconceptions, or incorrect prior knowledge, interfering with the acquisition of new knowledge. The process of replacing previously incorrect ideas with new and accurate ones is referred to as conceptual change. Which factors and to what extent they…
