This paper studies grade 7 (age 13) students' expressed understanding about the equal sign/notion of equivalence in order to investigate what aspects of the concept that could be seen as an established knowledge at lower secondary school/middle school. Using items from different instruments and combining these to a new one that covered a broad…

The aim of this study was to investigate individual differences in mathematical problem-solving among 3- to 5-year-old children (N = 328; n[subscript 3-year-olds] = 115, n[subscript 4-year-olds] = 167, n[subscript 5-year-olds] = 46). First, we examined the extent to which children in this age group were able to solve open and closed non-routine…

Auditory selective attention forms an important foundation of children's learning by enabling the prioritisation and encoding of relevant stimuli. It may also influence reading development, which relies on metalinguistic skills including the awareness of the sound structure of spoken language. Reports of attentional impairments and speech…

Statistical learning (SL), the ability to detect and extract regularities from inputs, has been considered as an early-maturing and domain-general mechanism that is critical for typical language development. However, recent evidence in neurotypical adults and children have found that individuals can vary in their SL abilities across linguistic and…

The goal of this study is to contribute to the field of Japanese pedagogy by examining how Japanese native speakers and learners of Japanese as a foreign language with American cultural backgrounds take stances in discussions in Japanese. As stancetaking is a fundamental human behavior (Du Bois & Karkkainen, 2012; Iwasaki, 2015; Kiesling,…

An important issue in second-language acquisition concerns the role of explicit information (EI) and how it is affected by individual differences. The present study explored this question through a partial replication and extension of Fernández (2008: Experiment 2), which investigated the effects of EI in processing instruction (PI) for the…

Prospective memory (PM), the ability to remember to execute an intention in the future, is critical for the performance of everyday tasks important for independence and quality of life. PM failures are associated with negative health, financial, and social outcomes, and are more frequent with increased age and can be even greater for older adults…

Preschoolers' language abilities are associated with their social interactions in early childhood classrooms. Few studies, however, have examined associations between social interactions and objective measures of children's real-time classroom language environments, information key to informing interventions to support preschool children at risk…

The development of human abilities stems from a complex interplay between genetic predispositions and environmental factors. Numerous studies have compared musicians with non-musicians on measures of musical and non-musical ability, frequently attributing musicians' superior performance to their training. By ignoring preexisting differences,…

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

Understanding language requires readers and listeners to cull meaning from fast-unfolding messages that often contain conflicting cues pointing to incompatible ways of interpreting the input (e.g., "The cat was chased by the mouse"). This article reviews mounting evidence from multiple methods demonstrating that cognitive control plays…

Drawing on Markus and Nurius's (1986) theory of possible selves and Higgins's (1987) theory of self-discrepancies, Dörnyei (2005, 2009) developed the L2 self-guide, a construct explaining the generation of motivation for language learning. Because Dörnyei focused on convergences in the source theories, L2MSS researchers have come to regard…

Objective: This study investigated collegians' (N = 466) vegetable consumption as a function of their food choice motivations, gender, and dietary habits. Method: Vegetarians and vegans (veg*ns, n = 94, 60% women), occasional meat eaters (n = 90, 66% women), and omnivores (n = 282, 43% women) completed the Food Choice Questionnaire and reported…

This study investigated the readiness of university faculty for online/distance learning (ODL) after two semesters of pandemic-driven remote teaching. We focused on faculty with prior ODL course design and online teaching experience, examining various aspects of their readiness: comfort with risk, identity disruption, teaching norms, equity and…

It is widely recognized that debugging is challenging for novice programmers and, as such, computing educators and researchers have called for explicit debugging instruction. Debugging requires various knowledge and skills, and different students may show different strengths and weaknesses. An understanding of such individual differences is…
