高低社交焦虑大学生不同情绪情境下的抑制控制研究

A Study on the Inhibitory Control under Different Emotional Situation among High and Low Social Anxiety University Students

摘要: 本研究采用Go/Nogo范式，考察社交焦虑和不同情绪情境(正性、中性、负性)对大学生抑制控制能力的影响。通过量表筛选共招募62名有效被试，其中高社交焦虑者31名，低社交焦虑者29名。研究采用2 (社交焦虑：高/低) × 3 (情绪情境：正性/中性/负性)混合实验设计。结果显示：(1) 高低社交焦虑组在不同情绪情境下的抑制控制表现存在差异。无论在何种情绪情境条件下，低社交焦虑组的整体表现均优于高社交焦虑组。(2) 社会焦虑与情绪情境在不同行为指标上的交互作用显著。对于高社交焦虑组，在负性情绪情境下其反应抑制能力受损，表现为Nogo试次错误率显著高于中性情境；在正性情绪情境下其执行速度与加工效能得到提升，表现为Go正确试次反应时显著短于中性情境。

Abstract: This study utilized the Go/Nogo paradigm to investigate the effects of social anxiety and various emotional situations (positive, neutral, and negative) on inhibitory control among university students. A total of 60 valid participants were recruited through scale screening, including 31 individuals with high social anxiety and 29 with low social anxiety. A 2 (social anxiety: high/low) × 3 (emotional situation: positive/neutral/negative) mixed experimental design was employed. The foundings are as follows: (1) The inhibitory control performance of the high and low social anxiety groups was different in different emotional situations. Regardless of the emotional situation, the overall performance of the low social anxiety group was superior to that of the high social anxiety group. (2) There was a significant interaction between social anxiety and emotional situation across different behavioral indicators. For the high social anxiety group, response inhibition was impaired under negative emotional situations, as evidenced by a significantly higher Nogo error rate compared to the neutral condition; meanwhile, their execution speed and processing efficiency were enhanced under positive emotional situations, reflected by significantly shorter Go reaction times compared to the neutral condition.
