The Effect of Attentional Focus on Temporal-Spatial Parameters of Gait

The direction of research on the development of a scientific and methodological tool for the analysis of spatial objects in order to determine their generalized spatial parameters was selected. An approach to the problem of modeling networks and groups of objects based on the synthesis of a weighted graph is proposed. The spatial configuration of objects based on the given conditions is described by a weighted graph, the edge length of which is considered as the weight of the edges. A generalization to the typical structure of a spatial graph is formulated; its essence is representation of nodal elements as two-dimensional (polygonal) objects. To take into account the restrictions on the convergence of the vertices described by the buffer zones, a complementary graph is formed. An algorithm for constructing the implementation of a spatial object based on the sequential determination of vertices that comply with the given conditions is proposed. Using the software implementation of the developed algorithm, an experiment was performed to evaluate the spatial parameters of the simulated objects described by typical graph structures. The following parameters were investigated as spatial ones

Event Based

Event-based prospective memory (PM) was investigated in children with Attention deficit/hyperactivity disorder (ADHD), using a novel experimental procedure to evaluate the role of working memory (WM) load, attentional focus, and reward sensitivity. The study included 24 children with ADHD and 23 typically-developing controls. The experimental paradigm comprised one baseline condition (BC), only including an ongoing task, and four PM conditions, varying for targets: 1 Target (1T), 4 Targets (4T), Unfocal (UN), and Reward (RE). Children with ADHD were slower than controls on all PM tasks and less accurate on both ongoing and PM tasks on the 4T and UN conditions. Within the ADHD group, the accuracy in the RE condition did not differ from BC. A significant relationship between ADHD-related symptoms and reduced accuracy/higher speed in PM conditions (PM and ongoing trials), but not in BC, was detected. Our data provide insight on the adverse role of WM load and attentional focus and the positive influence of reward in the PM performance of children with ADHD. Moreover, the relation between PM and ADHD symptoms paves the road for PM as a promising neuropsychological marker for ADHD diagnosis and intervention.

Perception Action

It is usually a mark of good design when technologies and tools that mediate goal-directed action are such that the user’s attentional focus is maintained on the intended ends of action rather than on the technologies and tools themselves. When the mediators become the focus, the continuity of goal-directed action is disrupted, and the flow of action can be re-directed. What then is the purpose of the projects designed by the RAAAF studio, as described by Rietveld, which seem to be intended to do both? Disruption of the continuity of goal-directed perception-action may prompt reflection about the circumstances at work, and in so doing provoke a transformation in habitual patterns of action and of thought. The project “The End of Sitting” is intended to remediate the adverse health effects of standard chair-dominated offices through an unconventional office landscape that prompts intermittent postural readjustments, boosting the levels of activity common in such settings. The project “Bunker 599” demonstrates that seemingly unremarkable features of the landscape can sometimes conceal aspects of culture’s history, and that design can function to draw attention to a hidden and even vanishing history. Design can enrich an individual’s sense of place in a stream of cultural history.
