儿童运动期望-价值信念对运动行为的影响——以儿童感知父母运动投入程度为中介变量

以Eccles父母社会化理论为基础,对595名二至六年级的小学生进行父母影响儿童运动参与研究,以期探讨感知父母运动投入程度是否对儿童运动期望-价值信念与运动行为的影响具有中介作用。运用线性回归分析方法对儿童感知父母运动投入的中介作用给予检验。结果表明,儿童的期望-价值信念对儿童感知父母的运动投入程度影响显著;儿童感知父母的运动投入程度对儿童运动行为影响显著;能力期望对运动行为影响显著,但该影响由于儿童感知父母运动投入程度的加入而变小或变得不显著,说明感知父母运动投入程度对儿童运动期望-价值信念与运动行为具有中介作用。

普通高校学生体育投入评价指标体系研究

建立科学、合理、高效的学生体育投入评估体系是高校体育工作的重点.在查阅相关文献和对普通高校体育专家调查访谈的基础上,运用数理统计分析法,构建出4项一级指标、13项二级指标、37项三级指标适用于普通高校学生体育投入评价的指标体系,拟通过评价体系的确立在高校体育教学中对评价体系各构成因素进行多方面不同程度的有效干预,从而达到增强学生体质健康之目的.

Remote Navigation of Turtle by Controlling Instinct Behavior via Human Brain-computer Interface

Brain-Computer Interface （BCI） techniques have advanced to a level where it is now eliminating the need lor hand-based activation. This paper presents a novel attempt to remotely control an animal＇s behavior by human BCI using a hybrid of Event Related Desynchronization （ERD） and Steady-State Visually Evoked Potential （SSVEP） BCI protocols. The turtle was chosen as the target animal, and we developed a head-mounted display, wireless communication, and a specially designed stimulation device for the turtle. These devices could evoke the turtle＇s instinctive escape behavior to guide its moving path, and turtles were remotely controlled in both indoor and outdoor environments. The system architecture and design were presented. To demon- strate the feasibility of the system, experimental tests were performed under various conditions. Our system could act as a framework for future human-animal interaction systems.
