The Development of Implicit Memory From Infancy to Childhood: On Average Performance Levels and Interindividual Differences

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues.

Does training with 3D videos improve decision-making in team invasion sports?

We examined the effectiveness of video-based decision training in national youth handball teams. Extending previous research, we tested in Study 1 whether a three-dimensional (3D) video training group would outperform a two-dimensional (2D) group. In Study 2, a 3D training group was compared to a control group and a group trained with a traditional tactic board. In both studies, training duration was 6 weeks. Performance was measured in a pre- to post-retention design. The tests consisted of a decision-making task measuring quality of decisions (first and best option) and decision time (time for first and best option). The results of Study 1 showed learning effects and revealed that the 3D video group made faster first-option choices than the 2D group, but differences in the quality of options were not pronounced. The results of Study 2 revealed learning effects for both training groups compared to the control group, and faster choices in the 3D group compared to both other groups. Together, the results show that 3D video training is the most useful tool for improving choices in handball, but only in reference to decision time and not decision quality. We discuss the usefulness of a 3D video tool for training of decision-making skills outside the laboratory or gym.     

The pupils’ view of electricity

Chemistry lessons were observed in the 8th grade of two West German schools over a period of a term. Boys received more attention from the teacher than girls. They were called on more often and they spontaneously gave their opinions more frequently. An equal proportion of girls’ and boys’ replies were praised and encouraged, but this meant that boys received more praise and encouragement in absolute terms. Teachers should be made aware of the problematic nature of their own behaviour, so that they can remove the discrimination against girls in chemistry education.     

Waiting for the Second Treat: Developing Culture‐Specific Modes of Self‐Regulation

The development of self‐regulation has been studied primarily in Western middle‐class contexts and has, therefore, neglected what is known about culturally varying self‐concepts and socialization strategies. The research reported here compared the self‐regulatory competencies of German middle‐class (N = 125) and rural Cameroonian Nso preschoolers (N = 76) using the Marshmallow test (Mischel, 2014). Study 1 revealed that 4‐year‐old Nso children showed better delay‐of‐gratification performance than their German peers. Study 2 revealed that culture‐specific maternal socialization goals and interaction behaviors were related to delay‐of‐gratification performance. Nso mothers’ focus on hierarchical relational socialization goals and responsive control seems to support children's delay‐of‐gratification performance more than German middle‐class mothers’ emphasis on psychological autonomous socialization goals and sensitive, child‐centered parenting.     

Inklusion im Sportunterricht

This review article provides an overview of the state of research in the English and German languages on inclusive physical education lessons. Studies published in journals and collected works between 2005 and 2014 were included. A systematic literature search was carried out and articles were selected according to predetermined criteria. A total of 74 articles were included in this review and categorized into the 3 superordinate topics attitude, lessons and qualifications. The compact presentation of the results revealed a tendency towards a positive attitude on inclusive physical education lessons of all participants questioned; however, teaching staff were critical of the concrete implementation of inclusive lessons and admitted that they had been insufficiently prepared for this during training. Pupils also expressed positive as well as negative experiences for participation in inclusive physical education lessons; however, some study results indicated that the acceptance of children with disabilities as well as their effectiveness of learning and physical activity can be improved by special interventional approaches. A core topic of inclusive lessons is a cooperation between the various participants. In this way problems are revealed, which can partly be attributed to the sometimes less clearly defined task profile and to discipline-specific training deficits of some participants. Finally, based on a critically constructive discussion, recommendations on further research approaches on inclusive physical education lessons in German-speaking regions are presented.
