Hot executive functioning (EF) – EF under emotionally or motivationally salient conditions – is a putative etiology of attention-deficit/hyperactivity disorder (ADHD), disruptive behavior problems (DBPs), and their related impairments. Despite two decades of research, the present study is the first review of the construct in youth ADHD, with a particular focus on the role of task design, age, and DBPs, as well as relevant conceptual and methodological considerations. While certain hot EF tasks have been investigated extensively (e.g., choice impulsivity), substantial inconsistency in measurement of the broader construct remains, severely limiting conclusions. Future research should a) consider the extent to which various hot EF tasks relate to one another, a higher order factor, and other related constructs; b) further investigate task design, particularly the elicitation of emotion or motivation and its anticipated effect on EF; and c) incorporate multiple levels of analysis to validate similarities and differences among tasks with regard to the affective experiences and cognitive demands they elicit. With improved measurement and conceptual clarity, hot EF has potential to advance the literature on etiological pathways to ADHD, DBPs and associated impairments and, more broadly, may represent a useful tool for understanding the influence of emotion and motivation on cognition.

This study examines the impact of group composition (one-on-one vs. multiple-to-multiple) and task design (student-selected vs. teacher-assigned) on undergraduate foreign language learners’ interactions in a mobile-based intercultural exchange. The participants, 27 Korean students learning English as a foreign language and 27 American students learning Korean as a foreign language, interacted in pairs and groups via mobile phones to complete weekly tasks for eight weeks. This study used mixed methods to analyze the data from mobile chat scripts, questionnaires, and interviews. The results indicated that the one-on-one and multiple-to-multiple groups did not differ significantly regarding contact frequency or number of written chats. However, one-on-one and multiple-to-multiple interactions did differ with regard to the quality of the interactions, reflecting the unique nature of each group composition. A one-on-one relationship promoted a higher level of intimacy and friendship, thus rendering it appropriate for providing linguistic and emotional support in learning foreign languages. In contrast, multiple-to-multiple communications were found to be more beneficial for learning about different perspectives on the target cultures. In terms of task design, teacher-assigned tasks guided students to engage in productive interactions effectively, whereas student-selected tasks elicited their personal investment in the tasks. Supporting social interdependence theory (Johnson & Johnson, 1989, 2009), we argue that the establishment of intimate relationships among group members may be the key to quality interactions in mobile-based intercultural exchanges.

Learner agency, the capability of individual human beings to make choices and act on these choices in a way that makes a difference in their lives (Martin, 2004), is instrumental in second language learning because attainment is only arrived at by learner choice (Pavlenko & Lantolf, 2000). If attainment is understood as learner engagement in synchronous, collaborative, spoken interaction which is thought to lead to gains in second language acquisition (SLA), then design considerations that harness learners’ agency towards that end is important. This study explores the relationship between learner agency and two different task types, namely an information-gap task and an opinion-sharing task in two peer-to-peer synchronous computer-mediated communication (SCMC) spoken interaction events. Students’ choices and how students act on these choices during tasks are analysed using a discourse analysis approach. Audio recordings of four dyads as cases were examined using three analytical dimensions: language functions of verbal interaction, cognitive processing and social processing. The results show that most learners used their agency to reconfigure the tasks from spontaneous to planned interaction, with some choices and actions relating to technology impacting detrimentally on interaction time in the target language. The different tasks were found to filter and channel different types of agency that learners could exercise, namely representational, organisational, and strategic agency as speech acts, and directional agency as a physical act. These types consisted of different natures and purposes and are presented as a framework. The information-gap task supported strategic agency and an opinion-sharing task supported personalisation and identity construction or representational agency.

This case study explores how a Chinese-American novice teacher acted as mediator in a telecollaboration with student teacher (ST) peers in the USA who designed tasks for his English as a foreign language (EFL) learners in China. The novice teacher was instrumental in mediating the student teachers’ task design process by providing feedback regarding technological and institutional constraints, and the nuances of his target student population. He appropriated and adapted the tasks to make them relevant for his EFL learners. Against the backdrop of the three dimensions of professional capital – human, social, and decisional – the research questions explored how the novice teacher used the different types of knowledge of context (pedagogical, institutional, technical) in relation to task design, and his perception of his role as mediator. Within a sociocultural framework for telecollaboration studies, this exploratory case study shares characteristics of ethnography, action research, and narrative inquiry. Data triangulation included text-based computer-mediated communication (CMC) data (Google Groups, emails), a narrative written by the novice teacher, and a semi-structured, reflective Skype interview with him. The findings indicate that he demonstrated high commitment, thorough preparation, continuous reflection, and development while navigating between his different roles of mediator, assessor, implementer, and field observer.

This study examined the individual and combined effects of the organisational-level variables of climate and task design, and the group-level variables of group citizenship behaviour (GCB), market orientation, group self-efficacy (GSE), and group climate for innovation (GCI) on work group service innovativeness. Specifically, this study theorised that work group service innovativeness is a product of both organisational (organisational climate and task design) and work group (GCB, market orientation, and GSE) contexts. Drawing upon the theories and literature, six hypotheses were derived. Data were collected through a 64-item questionnaire using a 7-point Likert scale from four hotels in Melbourne, Australia. Results indicated that organisational climate, task design, GCB, group self-efficacy, and group climate for innovation were significant predictors of work group service innovativeness, while market orientation was not. Limitations, future directions, managerial and research implications are explored.

This paper reports a Spanish-American telecollaborative project through which students used Twitter, blogs and podcasts for intercultural exchange over the course of one semester. The paper outlines the methodology for the project including pedagogical objectives, task design, selection of web tools and implementation. Using qualitative and quantitative data collection, the study explored how the application of Web 2.0 facilitated cross-cultural communication. How the use of digital technology affected the way in which the students viewed intercultural learning and peer feedback was examined. The findings showed that students viewed the online exchange as a superb venue for intercultural communication with native speakers. Through social engagements, students not only gained cultural knowledge but also became more aware of their own beliefs and attitudes toward their own culture. In addition, discussions on topics of tangible and intangible cultures afforded the opportunity to raise students’ awareness of cultural norms and practices. Peer feedback helped learners increase lexical knowledge, prevent language fossilization, and acquire native-sounding discourse. The study suggests that allocating sufficient time to complete each task and making personal commitment to online contributions are essential to successful intercultural exchanges.

The following paper presents two stages of an action research project involving two oral proficiency courses held in the virtual world Second Life. Course 1 was conducted during the Autumn of 2007. Based on the experiences of this course, we redesigned many aspects of it in order to improve student activity in terms of oral participation and gave the course again in Spring 2008. By analysing the recordings of four 90-minute sessions, two from each course, we were able to measure student participation based on floor space, turn lengths and turn-taking patterns, and in the study we discuss how different changes in design may have contributed to more favourable outcomes. Results seem to indicate that meaning focussed task design, which involves authenticity and collaborative elements, has a direct impact on learner participation and engagement. Furthermore, our results seem to suggest that technical and social initiations into a complex environment such as SL are important factors that have to be worked into the course design.
