AbstractAs part of a larger longitudinal study, this paper examines the development of Chinese students' EFL learning motivation throughout university undergraduate study, in an increasingly globalized local context. The study adopted a social constructivist perspective of language learning and combined research methods; the participants were over 1,000 undergraduates from 5 universities. The quantitative data were collected through a questionnaire (based on Gao et al. 2004) including motivational intensity and motivation types – instrumental, cultural, and situational, implemented annually from university entrance to graduation. The qualitative data consisted of individual and group interviews, student journals, and observations. Integrated data analysis revealed that sustained high-level long-term instrumental motivations coexisted with an increase of L2- oriented cultural motivations and situational motivation, particularly in the first and fourth year. The increased L2-oriented cultural motivations indicated neither ``ntegrativeness'' in the sense of becoming a member of the native English speaker community, nor a culturally neutral ``global identity.'' The increase of such L2- oriented cultural motivations was also accompanied by a sustained ``social responsibility'' motivation oriented to learners' home culture. Such complexities of motivational development call for further investigation in increasingly globalized EFL contexts.

Learning the skills to be a musician requires an enormous amount of effort and dedication, a long-term process that requires sustained motivation. Motivation for music is complex, blending relatively intrinsic and extrinsic motives. The purpose of this study is to investigate the motivation of musicians by considering how different aspects of motivational features interact. An international sample of 188 musicians was obtained through the use of an online survey. Four scales drawn from Self-Determination Theory (intrinsic, identified, introjected, and extrinsic regulation) were utilized along with other motivational constructs, including motivational intensity, desire to learn, willingness to play, perceived competence, and musical self-esteem. To integrate the variables into a proposed model, a path analysis was conducted among the motivation variables. Results showed that the intrinsic motives are playing the major role in the maintenance of the motivational system, while extrinsic motives are less influential. Support was found for a feedback loop, whereby desire to learn feeds into increased effort at learning (i.e., motivational intensity), leading to the development of perceived competence, which is then reflected back into increasing desire to learn. Increases in these variables help to create a virtuous cycle of motivation for music learning and performance.

AbstractRecent research on the conditions that facilitate cooperation is limited by a factor that has yet to be established: the accuracy of effort perception. Accuracy matters because the fitness of cooperative strategies depends not just on being able to perceive others’ effort but to perceive their true effort. In an experiment using a novel effort-tracker methodology, we calculate the accuracy of human effort perceptions and show that accuracy is boosted by more absolute effort (regardless of relative effort) and when cooperating with a “slacker” rather than an “altruist”. A formal model shows how such an effort-prober strategy is likely to be an adaptive solution because it gives would-be collaborators information on when to abort ventures that are not in their interest and opt for ones that are. This serves as a precautionary measure against systematic exploitation by extortionist strategies and a descent into uncooperativeness. As such, it is likely that humans have a bias to minimize mistakes in effort perception that would commit them to a disadvantageous effort-reward relationship. Overall we find support for the idea that humans have evolved smart effort detection systems that are made more accurate by those contexts most relevant for cooperative tasks.

The purpose of this study was to assess whether young children could reliability regulate exercise intensity production after several practice trials, without reference to objective feedback measures. The study used a new 10-point scale (Cart and Load Effort Rating [CALER] Scale), which depicts a child on a bicycle, at various stages of exertion, towing a cart in which the load increases progressively. After warm-up, 20 children, aged 7–10 years, performed an intermittent, effort production protocol at CALER 2, 5, and 8 on a cycle ergometer. This was repeated on three further occasions in the next 4 weeks. An increase in PO across trials (44, 65, and 79 W at CALER 2, 5, and 8, respectively) confirmed that the children understood the scale. A Bland and Altman limits of agreement (LoA) analysis and an intraclass correlation analysis (ICC) between trials (T) indicated that reliability improved with practice. Intertrial comparisons of overall reliability from T1 to T2 and from T3 to T4 ranged from 0.76 to 0.97 and an improvement in the overall bias ± 95% limits of agreement from −12 ± 19 W to 0 ± 10 W. This study is the first to apply more than two repeated effort production trials in young children and provides strong evidence that practice improves the reliability of effort perception in children. The data also provide preliminary evidence for the validity of the CALER Scale in children aged 7–10 years.

Two procedures were carried out to evaluate the effect of motivational intensity and relevance on attention. The experiment was designed to test the hypothesis that intense motivation acts consistently to reduce the number of cues utilized in a learning and/or performance task when these cues are relevant to the completion of a task. The results of the present study point to the existence of two functionally independent processes: (1) a span of attention process, concerned with the extent and breadth of attentional activity directed to stimuli which are relevant to a task; and (2) a scanning process, related to the fixation and recall of specific cue stimuli relevant to a task. It is this latter process which was postulated to be disrupted by high motivation.
