Loneliness becomes more prevalent as youth transition from childhood into adolescence. A key underlying process may be the puberty-related increase in biological stress reactivity, which can alter social behavior and elicit conflict or social withdrawal (fight-or-flight behaviors) in some youth, but increase prosocial (tend-and-befriend) responses…

This article explores the relation between curiosity and interest by examining how in-the-moment experiences of curiosity and of interest emerge out of exploratory behavior observed in infancy and early childhood. As experiential states, there is little to distinguish curiosity and interest. Descriptions of developing interests that refer to…

Research into the role of individual difference (ID) factors in the process of second and foreign language (L2) learning and teaching has been one of the most robust lines of inquiry in the field of second language acquisition (SLA; Dörnyei & Ryan, 2015; Griffiths & Soruç, 2020; Pawlak & Kruk, 2022). Most of these empirical…

While personality is relatively stable over time, it is also subject to change across the entire lifespan. On a macro-analytical level, empirical research has identified patterns of normative and differential development that are affected by biological and environmental factors, specific life events, and social role investments. On a…

Does the current drive to incorporate social and emotional learning (SEL) into the K-12 curriculum represent a positive reform that will lead schools to educate the "whole student" and ultimately boost young people's academic success? Or is it a distracting fad that comes with high opportunity costs? Common sense and considerable…

The key to the success of any online program is dedicating attention to student satisfaction. Student satisfaction with what and how they learn in an online classroom is an important variable to understand and can help instructors and course designers create an environment that fits students' needs. This can be achieved with adequate course…

This article presents a revised version of the writer(s)-within-community model of writing. Writing is conceptualized as a social activity situated within specific writing communities. Writing in these communities is accomplished by its members. The model proposes that writing is simultaneously shaped and bound by the characteristics, capacity,…

Individual differences refer to the unique ways each human being differs from another human being as expressed in behaviour or perceived in the physical appearance. Three factors of individual differences identified to be closely related to learning/acquisition of skills and performance of tasks. These are personality dimensions, self-efficacy and…

Based on Activity Theory, this article examines attitude formation in human learning as shaped by the experiences of individual learners with various learning objects in particular learning contexts. It hypothesizes that a learner's object-related perceptions, personality traits and situational perceptions may have different relationships with the…

Accounting for both bidirectional and interactive effects between parenting and child temperament can fine-tune theoretical models of the role of parenting and temperament in children's development of adjustment problems. Evidence for bidirectional and interactive effects between parenting and children's characteristics of frustration, fear,…

Individual difference factors of personality typology and learning style preference and their effect on second language acquisition have been the focus of several prominent SLA theorists over the past twenty-five years. However, few articles have demonstrated how individual learner difference research can be applied within a classroom by second…

This article analyzes latent variable models from a cognitive psychology perspective. We start by discussing work by Tuerlinckx and De Boeck (2005), who proved that a diffusion model for 2-choice response processes entails a 2-parameter logistic item response theory (IRT) model for individual differences in the response data. Following this line…

In 1921, Carl Jung wrote about four different types of personality, identified 24 centuries ago by Hippocrates. He theorized that these differences were not abnormalities in personality. Instead, he maintained that human behavior is predictable and classifiable that everyone has and acts upon personal preferences, established in early childhood.…

The assumption that effective leaders differ in some identifiable and fundamental ways from other people is still a large part of mainstream I/O psychology. Based on a research review on the trait theory of leadership and what is known about the concept of expertise, this paper attempts to find a convergence between leader and expert traits.…

The socioemotional factors, which influence students' trajectories on their pathways to reading success, are often overlooked in literacy screenings and reading instruction. This article outlines the connections between personality factors, in particular resilient personalities, and early literacy success. It also offers teachers a series of six…
