Does (Non‐)Meaningful Sensori‐Motor Engagement Promote Learning With Animated Physical Systems?

Previous research indicates that sensori‐motor experience with physical systems can have a positive effect on learning. However, it is not clear whether this effect is caused by mere bodily engagement or the intrinsically meaningful information that such interaction affords in performing the learning task. We investigated (N = 74), through the use of a Wii Balance Board, whether different forms of physical engagement that was either meaningfully, non‐meaningfully, or minimally related to the learning content would be beneficial (or detrimental) to learning about the workings of seesaws from instructional animations. The results were inconclusive, indicating that motoric competency on lever problem solving did not significantly differ between conditions, nor were response speed and transfer performance affected. These findings suggest that adult's implicit and explicit knowledge about physical systems is stable and not easily affected by (contradictory) sensori‐motor experiences. Implications for embodied learning are discussed.     

Measuring social capital through network analysis and its influence on individual performance

Studies of social networks highlight the importance of network structure or structural properties of a given network and its impact on performance outcome. One of the important properties of this network structure is referred to as social capital, which is the network of contacts and the associated values attached to these networks of contacts. This study provides empirical evidence of the influence of social capital and performance within the context of academic collaboration (coauthorship) and suggests that the collaborative process involves social capital embedded within relationships and network structures among direct coauthors. Association between scholars' social capital and their citation-based performance measures is examined. To overcome the limitations of traditional social network metrics for measuring the influence of scholars' social capital within coauthorship networks, the traditional social network metrics is extended by proposing two new measures, of which one is non-weighted (the power–diversity index) and the other (power–tie–diversity index) is weighted by the number of collaboration instances. The Spearman's correlation rank test is used to examine the association between scholars' social capital measures and their citation-based performance. Results suggest that research performance of authors is positively correlated with their social capital measures. The power–diversity index and power–tie–diversity index serve as indicators of power and influence of an individual's ability to control communication and information.

Reflective Functioning,Limit Setting,and Emotional Availability in Mother–Child Dyads

Objective. There is a need for better understanding the relation between parents’ mentalizing about their child and their actual behavior toward the child. Specifically, it is important to understand the significance of mentalization about discrete parental challenges in comparison with mentalization about the relationship in general in relation to their interaction with the child. This study aimed to examine parental mentalization and observed emotional availability. Design. Forty mothers were observed in a play situation with their children (aged 3–10 years) to rate the emotional availability in the interaction. Mothers were also interviewed with the parent development interview and about parental limit setting to assess parental reflective functioning. Results. Analyses showed moderate correlations between the reflective functioning scores and the emotional availability dimensions. Approximately 15% of the variance in emotional availability scales could be accounted for by the reflective functioning ratings. Conclusions. The results suggest that parents’ ability to mentalize about limit setting behaviors may affect interactions between the parent and child.     

Learning qualitative and quantitative reasoning in a microworld for elastic impacts

From a psychological point of view efficient teaching by means of an intelligent tutoring system necessarily involves that the communication of knowledge is adapted to the requirements of the learner: to her cognitive abilities, her pre-instructional knowledge and her learning capabilities. To tackle these topics in a precise way, we have developed the artificial-intelligence-based microworld DiBi (disk billiard) and MULEDS, a multi-level diagnosis system. The microworld DiBi sets up a learning environment which simulates elastic impacts as a subtopic of classical mechanics. DiBi enables and supports reasoning on different levels of mental domain representation ordered along the dimension ‘qualitative/quantitative’. This way of representing the domain provides a basis for passive adaptation in an advanced way. Correspondingly, active adaptation is supported by MULEDS, wherein student modeling is realized by assessing the student’s correct and/or incorrect domain-specific knowledge at these different levels. Within this psychological perspective, the use of instructional tools, such as the microworld DiBi and the computerized diagnosis system MULEDS, aims at gradually supporting and guiding the student in the construction of more and more powerful an sound domain representations. The progression through these levels of domain representation will enable the student to solve the problems posed by the domain in a flexible way.
