Recent evidence suggests that cardiovascular fitness and gross motor skill performance are related to neurocognitive functioning by influencing brain structure and functioning. This study investigates the role of resting-state networks (RSNs) in the relation of cardiovascular fitness and gross motor skills with neurocognitive functioning in healthy 8- to 11-year-old children (n = 90, 45 girls, 10% migration background). Cardiovascular fitness and gross motor skills were related to brain activity in RSNs. Furthermore, brain activity in RSNs mediated the relation of both cardiovascular fitness (Frontoparietal network and Somatomotor network) and gross motor skills (Somatomotor network) with neurocognitive functioning. The results indicate that brain functioning may contribute to the relation between both cardiovascular fitness and gross motor skills with neurocognitive functioning.  相似文献   

Effects of contrasting colour patterns of the ball in the volleyball reception     

Matthieu Lenoir  Joost Vansteenkiste  Jelle Vermeulen  Dirk de Clercq 《Journal of sports sciences》2013,31(8):871-879

The effects of three different colour patterns on the surface of volleyballs (versus that of a plain white ball) on the behaviour of a reception player were examined by presenting sidespin volleyball serves. Expert (n = 10) and novice (n = 10) volleyball players intercepted volleyballs projected straight at them or at an initial angle of 9.5° outwards but eventually curving towards the players' original position. In the latter trajectories, players generally took one or more steps laterally before returning to the landing position of the ball. These excursion patterns were significantly more pronounced with the white balls than the coloured balls. Differences between balls of different colour combinations were also observed. The first finding supports the thesis that next to a prospective type of control, such as on-line maintenance of a certain spatiotemporal relationship between the player and the ball, properties of the ball itself allow prediction of the future path of the ball. Differences between types of colour patterns are explained within the framework of the between-colours wavelength contrasts of each type of ball.  相似文献   

Measuring the Welfare Effects of Public Television     

Joost Poort  Barbara Baarsma 《Journal of Media Economics》2016,29(1):31-48

Based on an explorative case study in the Netherlands, the authors developed a methodology to assess the welfare effects of public service broadcasting. This methodology consists of a combination of revealed and stated preferences, using readily available data for all programs broadcast in the evening in 2011. The results cover both individual programs and an aggregate level. Because the data used encompass both public and commercial programs, the analysis allows for comparisons between these.  相似文献   

Teaching and testing mathematical problem solving by offering optional assistance     

Meijer  Joost  Riemersma  Fré 《Instructional Science》2002,30(3):187-220

Transfer capability is usually defined as theability to apply acquired knowledge and skillsin novel situations.The experiment reported here concerned transferin mathematics education. An experimental programme was constructed, based on strengtheningthe connection of strategic and domain specificknowledge and offering hints during teaching aswell as during testing.Subjects were first graders from secondaryeducation in the Netherlands, from two schools,two classes each. Students from these fourclasses were randomly allocated either to theexperimental or the control group.The experimental computer-supported teachingprogramme was offered once a week during sixweeks; the control group received regularmathematics instruction.After controlling for the effects of thecovariates intelligence, mathematics aptitudeand anxiety, it was shown that the experimentalsubjects performed significantly better on aposttest than subjects in the control group.The results suggest that the experimentalinstruction method enhances mathematics problemsolving ability more strongly than traditionalinstruction. Upon closer examination thiseffect appears to be restricted to subjectsalready relatively high in intelligence andmathematical ability. This finding is notuncommon in intervention research, and issometimes referred to as the Matthew orthe fan-spread effect.  相似文献   

Self-efficacy, task complexity and task performance: Exploring interactions in two versions of vocabulary learning tasks     

Xiaoli Wu  Joost Lowyck  Lies Sercu  Jan Elen 《Learning Environments Research》2012,15(1):17-35

The present study aimed for better understanding of the interactions between task complexity and students?? self-efficacy beliefs and students?? use of learning strategies, and finally their interacting effects on task performance. This investigation was carried out in the context of Chinese students learning English as a foreign language in a university in China. The participants were 78 second-year university students (mean age?=?20.9?years). This study used a repeated-measures design with task complexity as the within-participants factor, and task sequence as the between-participants factor. Results indicated a significant task effect for self-efficacy beliefs and task performance, and a significant interaction effect of sequence with task complexity for learners?? self-efficacy beliefs in learning for both task versions, learners with higher self-efficacy beliefs had better task performances than learners with lower self-efficacy beliefs. The results also revealed a strong correlation between self-efficacy and the use of learning strategies for both tasks.  相似文献
