Visuelle Bewegungskontrolle geführter Kraftübungen bei jungen Erwachsenen und Senioren

In the context of strength training in rehabilitation, visual movement control can be helpful to ensure correct movements. However, there are only a few studies that deal with the effectiveness of feedback during resistance exercises. To investigate the effect of feedback during guided exercise, 18 young adults (28.8?±?5.5 years) and 12 senior citizens (67.9?±?4.1 years) were tested. Subjects performed shoulder press exercises (3 sets, 15 repetitions) with and without visual movement control in a randomized order. On day 1, the subjects trained without load, and on day 2 they trained at 50% of their single repetition maximum. Joint articulation at the elbow was recorded using elbow extension and flexion. Autocorrelation was used to determine the reproducibility of movements. Subjects achieved better reproducibility of the movement with feedback than without (χ²?=?19.73; p?<?0.001). There was no effect of the load on motion accuracy (p?>?0.05), but the age group showed a significant effect (χ²?=?6.00; p?=?0.014). The younger group shows a higher degree of movement accuracy. In summary, visual movement control is useful in guided exercises to control movement execution. In clinical setting, this may be a way to control the motion performance of guided strength exercises and to ensure purposeful muscle work. Further studies should clarify the effect of visual feedback on the movement quality in unguided strength exercises.     

Promotion of students’ mastery goal orientations: does TARGET work?

Achievement goal orientations are important for students’ ongoing motivation. Students with a mastery goal orientation show the most advantageous achievement and motivational patterns. Much research has been conducted to identify classroom structures which promote students’ mastery goal orientation. The TARGET framework is one example of these efforts and provides six instructional dimensions (task, authority, recognition, grouping, evaluation, time), which should form a classroom structure that fosters a mastery goal orientation. The aim of this study was to examine the entire multi-dimensional TARGET framework and its impact on mastery goal orientation in a longitudinal study with 1680 secondary school students. CFAs confirmed the existence of one latent factor TARGET comprising the six proposed dimensions. This study also provides the first empirical evidence, based on longitudinal data, that TARGET has a positive impact on student mastery goal orientations.     

Effects of orthographic consistency and word length on the dynamics of written production in adults: psycholinguistic and rTMS experiments

Reading and Writing - Recent studies on written word production aim at studying how information is transmitted between central (linguistic) and peripheral (motor) processes. Neurocognitive models...     

Les Théories Implicites du Développement et de l’Education

The terms «implicit developmental and educational theories» refer to parents’ and teachers’ knowledge of developmental processes and educational action. The author presents a synthesis of studies concerned mainly with children’s socioemotional development, published between 1980 and 1986 and carried out in Europe as well as in the United States. She focuses mainly on studies of authors who work within the cognitive development framework. She also presents studies of authors with regard to other aspects of personality which can be integrated into a constructive framework of educational action, within the larger framework of action theory.
