Abstract

To execute a motor solution to a given task, individuals search through the space of movement possibilities guided by information that arises from the interaction with task and environment. Through this search, individuals seek to avoid inappropriate solutions through local minima in the task space. The processes that lead to some but not all individuals avoiding local minima and finding solutions is not yet understood. Based on the tenets of ecological psychology for perception and action, we examined in two experiments the hypothesis that the incapacity to differentiate errors (performance of an inappropriate solution) from inherent variability would interfere with the perception of properties of the task space and result in a longer time performing an inappropriate solution for the task before exploration of other solutions. Inherent variability was shown to be a direct predictor of the changes in the search strategies. Also, we found that the specifics of the search patterns could predict the performance in the task. Thus, the pattern of motion through the task space affords perception of specific properties of this space guiding individuals in the evolving dynamics of exploration or exploitation.

摘要

为了执行针对给定任务的运动解决方案，个人在由与任务和环境交互作用而产生的信息指导下的移动可能性空间中进行搜索。通过这种搜索，个人试图通过任务空间中的局部最小值来避免不合适的解决方案。导致一些但不是全部个体避免局部极小并找到解决方案的过程尚未被理解。根据生态心理学关于感知和行动的原则，我们在两个实验中检验了以下假设：无法将错误（执行不合适的解决方案）与固有可变性区分开来，这会干扰对任务空间特性的感知，并导致在探索其他解决方案之前，需要较长时间对任务执行不合适的解决方案。内在变异性被证明是搜索策略变化的直接预测因子。此外，我们发现搜索模式的细节可以预测任务的性能。因此，通过任务空间的运动模式使人们可以感知该空间的特定属性，从而指导个人进行不断发展的探索或开发动态。
