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…

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)…

This study investigated whether L2 English learners' prosodic properties in speech acts change as they are immersed in the English-speaking academic community over time, and if so, what individual and contextual factors (proficiency, orientation to language study, and target language contact) potentially affect these changes. Forty-seven Japanese…

Using a multilevel latent growth curve modeling (LGCM) approach, this study examined longitudinal change in levels of physical fitness performance over time (i.e. four years) in young adolescents aged from 12-13 years. The sample consisted of 6622 students from 138 secondary schools in Singapore. Initial analyses found between-school variation on…

This article proposes a comprehensive approach based on structural equation modeling for assessing the amount of trait-level change derived from faking-motivating situations. The model is intended for a mixed 2-wave 2-group design, and assesses change at both the group and the individual level. Theoretically the model adopts an integrative…

The complex phenomenon of intraindividual and interindividual differences in the development of occupational aspirations and factors influencing this development were examined in a longitudinal sample of 5,727 Korean adolescents over a 4-year period. A downward trajectory of occupational aspirations from junior high school to the first year of…
