情绪状态对学习者虚拟图形加工认知负荷的影响研究

Research on the Influence of Emotional State on Learners’Cognitive Load of Virtual Graphic Machining

本研究考察学习者情绪状态对沉浸式虚拟图形加工认知负荷的影响,同时探讨情绪状态与认知任务特征(项目数量和呈现时间)的交互作用效果。结果显示:(1)学习者在积极情绪状态下,虚拟图形识记的主、次任务绩效表现更好,投入心理努力更高。(2)情绪状态与呈现时间的交互作用显著影响次任务正确率:呈现时间为0.5s时,积极情绪状态下的次任务正确率高于消极情绪;0.8s时,两者无显著差异。(3)情绪状态与项目数量的交互作用显著影响心理努力评价,项目数量为5个时,积极情绪状态下的心理努力评价高于消极情绪;其他数量时,两者差异不显著。研究结果表明,在沉浸式虚拟环境中,学习者积极情绪状态下的客观认知负荷更低,投入心理努力更多。情绪状态对虚拟学习的影响受到认知加工任务的调节,当加工材料数量较多、呈现时间较短时,积极情绪状态的学习优势更为明显。

This paper has investigated the influence of learners’emotional state on cognitive load of virtual graphic machining of immersion type,and discussed the interaction effect of emotional state and cognitive task characteristics(number of projects and presentation time).The results show that:1.Under the positive emotional state,the main and sub-class task performance memorized by virtual graphic is better,and psychological effort will be put much higher.2.The interaction of emotional state and presentation time affects submission’s accuracy obviously.When presentation time is 0.5s,submission’s accuracy under active emotional state is higher than negative emotion.When presentation time is 0.8s,the both have no significant differences.3.The interaction of emotional state and the number of projects affect the evaluation of psychological effort obviously.When the number of projects is 5,the evaluation of psychological effort under active emotional state is higher than negative emotion.When the number of projects is something else,the both have no significant differences.The research results show that in the immersion virtual environment,the learners’objective cognitive load under positive emotional state is much lower,and the psychological effort is put much more.The influence of emotional state on virtual learning is regulated by cognitive processing tasks.When the number of processing materials is much more,and the presentation time is rather short,the learning advantages of positive emotional state are more obvious.
