The main purpose of the present research was to investigate school intrinsic and extrinsic motivation, and amotivation as
a function of age in a sample of 1,600 elementary and high school students aged 9–17 years. First, results revealed a systematic
decrease in intrinsic motivation and self-determined extrinsic motivation from age 9 to 12 years, a slow stabilization until
15 years old, followed by an increase after that point. Second, non self-determined extrinsic motivation showed a decrease
up to 12 years old and a slow stabilization after that point. Finally, amotivation was relatively low and stable from age
9 to 17 years. Of importance is that the present results also revealed that teacher autonomy support mediated the age-school
motivation relationships. The present results underscore the importance of a better understanding of the mechanisms through
which lower intrinsic motivation and self-determined extrinsic motivation in older students take place, eventually leading
to appropriate interventions and optimal motivation in students of all ages. 相似文献

The extant literature on manual laterality in non-human primates is inconclusive, plagued by inconsistent or contradictory findings and by disturbing methodological issues (e.g. uncontrolled influential factors, comparability issues). The present study examined hand preference and its flexibility in 15 red-capped mangabeys (C. t. torquatus) and 13 Campbell's monkeys (C. c. campbelli), two species that differ in their degree of arboreality. We investigated the influence of the spatial position of the object on hand preference for reaching. We considered spontaneous behaviour (reaching for food during daily feeding) and an experimental task: the QHP task. The QHP is a task that is used in humans. This is a simple reaching task that involves high spatial constraints on hand use. In our study, the subject had to reach for items that were placed on a semi-circle in front of it on five positions, including in the centre position, in the ipsilateral space and in the contralateral space. We assessed hand preference for reaching in front (baseline condition), and we examined how this preference changed when reaching in lateral positions. For reaching in front, about half of the subjects were lateralized and no group-level bias occurred, for both spontaneous and experimental conditions. When considering reaching in the lateral positions, we observed that the position of the object influenced hand use: individuals used the hand that was closest to the object. The results are discussed in relation to previous findings in humans and in non-human primates and regarding theories on handedness and flexibility of hand preference. 相似文献

In coincidence‐timing studies, children have been shown to respond too early to slower stimuli and too late to faster stimuli. To examine this velocity effect, children aged 6, 7.5, 9, 10.5, and adults were tested with two different velocities in a prediction‐motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. A similar velocity effect, resulting in later responses for the faster velocities than for the slower, was found primarily in the three younger groups of children (for the longer occlusion conditions: 600–1,320 milliseconds). However, this effect was not seen in all children in these groups. Individual analyses showed that this velocity effect, when present, is linked to the use of distance rather than time information, or to the confusion between these in extrapolating the occluded trajectories. The tendency to use one type of information or the other is a good predictor of accuracy and variability in this task and a good indicator of the development stage of the participants. Across development, children tend to initially use distance information with poor accuracy but relative consistency in responses. In a second stage, they use time and distance information alternatively across trials trying to find a better source of information with still poor accuracy and now great variability. In a final stage, they use time information to reach consistency and accuracy in their responses. This chronology follows the stages proposed by Savelesbergh and Van der Kamp (2000) explaining development with an initial stage of ‘freezing’ non‐optimal relationships between information and movement, then a ‘freeing’ stage during which new solutions are searched for, and finally an ‘exploiting’ stage with an optimal relationship between information and movement. 相似文献

ABSTRACTThis study extends the research and theory on work motivation by examining temporal stability and change in employees’ self-determined work motivation profiles and their differential relations to various predictors and outcomes. We gathered data at two time points over a 24-month period from a sample of 438 newly registered public health care nurses. Results of latent profile and latent transition analyses revealed four distinct profiles (strongly, moderately, self-determined, and poorly motivated), estimated from the position of global and specific behavioural regulations on the motivation continuum proposed by self-determination theory. These profiles were entirely stable at the within-sample level, although within-person changes in profile membership occurred for 30–40% of employees. Of particular interest, perceptions of job resources were consistently associated with greater likelihood of membership in the strongly and moderately motivated profiles. These profiles were also consistently associated with lower emotional exhaustion and intentions to leave the occupation and the organization and with higher in-role performance compared to the self-determined and poorly motivated profiles. 相似文献
