【摘要】：本研究从具身认知的角度研究个体的延迟选择行为,重点在于探讨和分析不同冲突水平下手臂动作对延迟选择的影响。基于以往研究,本研究通过两个实验,诱发被试在维持手臂动作的同时阅读并完成决策任务,分别考察在不同冲突水平下单侧和双侧手臂动作对延迟选择的影响。在实验一中,将被试随机分配到手臂弯曲或手臂伸展组,要求被试在维持单侧手臂动作的同时阅读并完成决策任务,以探讨不同冲突水平下单侧手臂动作对延迟选择的影响。结果显示,冲突水平会对个体的延迟选择行为具有显著影响,当决策冲突高时,被试更倾向于延迟选择；而不同的手臂动作条件下,个体的延迟选择行为并没有显著差异。在实验二中,将被试随机分为一致性(右手弯曲且左手伸展)和非一致性组(右手伸展且左手弯曲),要求被试在维持双侧手臂动作的同时阅读并完成决策任务,以探讨不同冲突水平下双侧手臂动作对延迟选择的影响。结果发现,双侧手臂动作对延迟选择具有显著影响,相较于一致性条件,非一致性条件下的被试更倾向于延迟选择。当冲突水平高时,双侧手臂动作对延迟选择无显著影响。相应地,本研究也发现在低冲突水平下,双侧手臂动作对个体的决策倾向具有边缘显著影响,相较于非一致性条件,个体在一致性条件下会更倾向于在当前两个可选项中做出选择,而当冲突高时双侧手臂动作对个体的延迟选择无显著影响。综合两个实验的研究结果,本研究认为在低冲突水平下,双侧手臂动作会影响个体的延迟选择行为,相较于一致性条件(右手伸展且左手弯曲),非一致性条件(右手弯曲且左手伸展)下的被试应会更倾向于延迟选择。
[Abstract]:In this study, the delayed selection behavior of individuals was studied from the perspective of personal cognition, with the emphasis on the analysis of the effects of arm movements on delayed selection at different conflict levels. Based on previous studies, two experiments were conducted to induce the subjects to read and complete the decision-making tasks while maintaining arm movements, and to investigate the effects of unilateral and bilateral arm movements on delayed selection at different conflict levels. In the first experiment, the subjects were randomly assigned to the arm bending or arm stretching group. The subjects were asked to read and complete the decision-making task while maintaining the unilateral arm movement, in order to explore the effect of unilateral arm action on delayed selection at different conflict levels. The results showed that the level of conflict had a significant effect on the delayed selection behavior of individuals, and when the decision-making conflict was high, the participants were more inclined to delay selection, but there was no significant difference in the delayed selection behavior of individuals with different arm movements. In experiment 2, subjects were randomly divided into two groups: consistency group (right hand bending and left hand stretching) and inconsistent group (right hand stretching and left hand bending). Subjects were asked to read and complete decision-making tasks while maintaining bilateral arm movements. To investigate the effects of bilateral arm movements on delayed selection at different conflict levels. The results showed that bilateral arm movements had a significant effect on delayed selection, and subjects with inconsistent arm movements were more inclined to delay selection than those with inconsistent conditions. When the conflict level was high, bilateral arm movements had no significant effect on delayed selection. Accordingly, this study also found that, at low conflict levels, bilateral arm movements had significant marginal effects on individuals' decision-making propensity, compared with non-consistent conditions. In the case of consistency, individuals tend to choose between the current two options, but bilateral arm movements have no significant effect on the delayed selection of individuals when the conflict is high. Combined with the results of two experiments, this study suggests that bilateral arm movements may affect the delayed selection behavior of individuals at low conflict levels. Subjects with inconsistent conditions (right hand bending and left hand stretching) should be more inclined to delay selection than consistency conditions (right hand extension and left hand bending).
