The Utility of the State Space Grid Method for Studying Peer Interactions in Youth Sport

Although previous studies indicate that peer interactions represent an important component of the youth sport experience, studies examining peer interactions in the sport context are limited. Furthermore, the methodological tools commonly used to investigate peer interactions have restricted researchers’ understandings of the complex, reciprocal nature of these experiences. This paper outlines the potential contribution of a novel dynamic systems-based methodology, the state space grid method (SSG; Lewis, Lamey, & Douglas, 1999 Lewis, M. D., Lamey, A. V. and Douglas, L. 1999. A new dynamic system method for the analysis of early socioemotional development. Developmental Science, 2: 457–475. [Crossref], [Web of Science ®] , [Google Scholar]), to the study of peer interactions in sport. Concrete recommendations to guide the practical application of the SSG method to future peer research in youth sport are presented.     

The Induction of Color Blindness by a Technique of Hypnotic Suggestion

The relative efficacy of auditory feedback, varying in the amount of information contained in the feedback signal, for the self-control of heart rate (HR) was determined by comparing groups of 10 Ss who received either: (a) continuous proportional feedback, (b) discontinuous proportional feedback, (c) binary feedback, (d) heart sounds, or (e) no feedback. At each of two sessions Ss were given eight trials in each direction on which they were to raise or lower their HR.

Without regard to the amount of information contained in the signal, presentation of auditory feedback aided Ss in raising HR relative to Ss who received no feedback; however, feedback did not yield an advantage in lowering it. These results suggest that perhaps the informing quality of feedback is multidimensional and also that perhaps the mechanisms involved in acceleration and deceleration of HR may be different.     

Who is good at this game? Linking an activity to a social category undermines children's achievement

Children's achievement-related theories have a profound impact on their academic success. Children who adopt entity theories believe that their ability to perform a task is dictated by the amount of natural talent they possess for that task--a belief that has well-documented adverse consequences for their achievement (e.g., lowered persistence, impaired performance). It is thus important to understand what leads children to adopt entity theories. In the experiments reported here, we hypothesized that the mere act of linking success at an unfamiliar, challenging activity to a social group gives rise to entity beliefs that are so powerful as to interfere with children's ability to perform the activity. Two experiments showed that, as predicted, the performance of 4- to 7-year-olds (N = 192) was impaired by exposure to information that associated success in the task at hand with membership in a certain social group (e.g., "boys are good at this game"), regardless of whether the children themselves belonged to that group.     

On disenthralling ourselves from the enchantment of psychology

Pastors who assume that the insights of psychology have superseded those of the Scriptures, the great philosophers, or classic literary works are shortchanging themselves and their parishioners. These insights may be true and useful on many occasions, but they do not represent the full truth about the human condition. Examples from the novels of Jane Austen illustrate the larger truth of ill that human choices may be willed for the sake of human good or ill and that the human community provides the context for understanding and evaluating those choices.     

Regional differences in brain volume predict the acquisition of skill in a complex real-time strategy videogame

Previous studies have found that differences in brain volume among older adults predict performance in laboratory tasks of executive control, memory, and motor learning. In the present study we asked whether regional differences in brain volume as assessed by the application of a voxel-based morphometry technique on high resolution MRI would also be useful in predicting the acquisition of skill in complex tasks, such as strategy-based video games. Twenty older adults were trained for over 20 h to play Rise of Nations, a complex real-time strategy game. These adults showed substantial improvements over the training period in game performance. MRI scans obtained prior to training revealed that the volume of a number of brain regions, which have been previously associated with subsets of the trained skills, predicted a substantial amount of variance in learning on the complex game. Thus, regional differences in brain volume can predict learning in complex tasks that entail the use of a variety of perceptual, cognitive and motor processes.
