title: Fatiguing verbal working memory to reduce explicit hypothesis testing during skill acquisition: A new implicit motor learning paradigm?

authors: Boaz-Curry, Ko-Tahi-Ra

abstract: How we learn novel motor skills is crucial for motor performance. Motor skills learned through implicit processes have been shown to have higher neural efficiency, lower likelihood of interference from conscious control during motor output, and more stable performance under pressure, stress, fatigue and multitasking situations (Maxwell, Masters & Eves, 2000; Steenbergen, Van Der Kamp, Verneau, Jongbloed-Pereboom & Masters, 2010; Zhu, Yeung, Poolton, Lee, Leung & Masters, 2015). These performance benefits are sought after in both clinical and sporting domains, and make implicit motor learning a viable alternative to explicit forms of learning. However, current implicit motor learning paradigms have encountered limitations that hinder their practical application (Lam, Maxwell & Masters, 2009; Zhu et al., 2015); therefore, new implicit motor learning paradigms need to be created. This thesis investigated whether cognitive fatigue can be used to encourage novices to perform a novel motor task in an implicit manner. We hypothesized that inducing cognitive fatigue in people would suppress verbal working memory activity, thereby minimising hypothesis testing about the task to be performed and causing implicit motor learning. The research was conducted on thirty-three healthy adults (women=19, men=14; mean age= 23.3±5.5) who reported limited golf experience. All participants were randomly allocated to one of two treatment conditions: control (non-fatigued) or experimental (fatigued). We analysed the differences in verbal working memory performance, motor skill performance and hypothesis testing measures between the two groups. Our results showed that participants in the experimental condition reported a significant increase in subjective feelings of fatigue following the intervention; however, this was not reflected by a decrease in working memory activity. The results also illustrated no significant differences in motor performance or hypothesis testing between the two groups. Overall, the cognitive fatigue task was shown to successfully alter self-reported levels of fatigue (VAS-f), although we speculate that the fatigue levels produced by the intervention were not sufficient to suppress working memory activity during performance of a novel motor task.

title: A multi-player educational game for story writing

authors: Mayo, Michael

subjects: computer science

abstract: In this short paper, a multi-player interactive game called STORYWORLD BUILDER is described. The game enables children to collaboratively build a virtual “story world” and then role-play characters in that world. The educational purpose of the system is to motivate children to write better stories, by providing them with a collaborative, interactive, computer game-like environment in which stories can be enacted. We are interested in whether such a system can improve children’s story writing skills.

title: Indigenizing outdoor play in New Zealand: A conversation analysis approach

authors: Bateman, Amanda

abstract: This chapter focuses on a single case analysis of one trip to a local bush reserve in New Zealand. The observations included in this chapter begin by exploring the way in which a promise to the Maori God Tane Mahuta is managed by the teachers and children at the beginning of the excursion. The promise made is part of the mundane, everyday activity engaged in by these children and teachers during their weekly visit to the bush reserve, where every child is required to recite a phrase that promises not to hurt the creatures, animals or plants of Tane Mahuta when they are playing in the forest. In the first of the video-recorded episodes, explicit reference to Tane Mahuta is initially oriented through one of the children reciting the promise, unprompted, at the beginning of the recording. The second observation reveals one of the teachers explaining to a child the rules of entering the forest: that you have to ask permission from Tane Mahuta before you enter. When a child does not want to say the promise, he is encouraged to do so collaboratively with the teacher before entering the forest. Only once the child has said the promise does he enter, demonstrating the importance of the verbal commitment and participation in the accountable action of promise-making by the participants prior to entering the forest.
