Duo-ethnography is a collaborative methodology in which participants juxtapose their experiences around a topic to parse multiple perspectives. It explicitly positions ethnographers as sources of information, not data collectors. This method has been used to explore racial identities, class dynamics, decolonizing pedagogies, and gender in academic…

This Perspective article expands on a working memory-dependent dual-process model, originally proposed by Zheng et al., to elucidate individual differences in the testing effect. This model posits that the testing effect comprises two processes: retrieval-attempt and post-retrieval re-encoding. We substantiate this model with empirical evidence…

Social gaming--online gameplay involving digital interactions with others--is a common form of social media use among adolescents. Research on this topic has neglected the social aspect of gaming and the potential role of social gaming in adolescent development. In this article, we define social gaming, drawing on interdisciplinary theories to…

This special issue revisits a classic topic in linguistic theory, A-bar movement, applied to developing and bilingual grammars. We claim that A-bar movement, or filler-gap dependencies, is still the quintessential linguistic phenomenon to illustrate the interaction between the biological endowment, the experience with language (past and present),…

It is widely accepted that written corrective feedback (WCF) is an effective tool for helping learners develop their L2 knowledge. Yet, it remains inconclusive as to which type of WCF can best facilitate L2 learning. In recent years, many second language acquisition (SLA) researchers agree that "direct" and "focused" WCF may be…

Student development theory has been an important guide in practice; however, few theories focus on both the individual and the influence of the environment. Spencer's (1997) Phenomenological Variant of Ecological Systems Theory (PVEST) examines the individual, the environment, and the role of environmental feedback on self-perceptions, with a…

This article discusses the issues of the basic processes underlying intelligence, considering both historical and contemporary perspectives. The attempt to elucidate basic processes has had, at best, mixed success. There are some problems with pinpointing the underlying basic processes of intelligence, both in theory and as tested, such as what…

This chapter explains recovery as an individual process and as an organizing framework for addressing substance use disorders.

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…

Errors are inevitable in most learning contexts, but under the right conditions, they can be beneficial for learning. Prior research indicates that generating and learning from errors can promote retention of knowledge, higher-level learning, and self-regulation. The present review proposes an integrated theoretical model to explain two major…

Despite undeniable advances in research on language learning strategies in the last several decades, empirical investigations of actions and thoughts that learners engage in to better understand and use grammar structures in different contexts, or grammar learning strategies (GLS), remain scarce. Moreover, there is a paucity of studies examining…

In this article Chris Higgins considers two works by Jean-Luc Nancy -- "On Being Singular Plural" and "Why Are There Several Arts and Not Just One?" -- in light of the formative task to do justice to the diverse dimensions of oneself given the offerings and demands of the world, a task made difficult by our finitude and the…

This book traces and summarizes the author's theoretical insights and empirical findings in the field of foreign language education. The volume explores themes such as individual differences in L1 ability and their connection to L2 aptitude and L2 achievement, L2 anxiety as an affective or cognitive variable, and the relationship between L1 and L2…

The burgeoning field of third language (L3) acquisition has increasingly focused on intermediate stages of language development, aiming to establish the groundwork for comprehensive models of L3 learning that encompass the entire developmental sequence. This article underscores the importance of a robust epistemological foundation, advocating for…

Estimation of within-trial interactions in meta-analysis is crucial for reliable assessment of how treatment effects vary across participant subgroups. However, current methods have various limitations. Patients, clinicians and policy-makers need reliable estimates of treatment effects within specific covariate subgroups, on relative and absolute…
