Objective To explore the value of a gradient-based dual-player pattern matching task in the e-valuation of friendship quality.Methods A total of 24 pairs(n=48)of strangers and 40 pairs(n=80)of friends were recruited.All of them performed the pattern matching task adapted from previous research,and the task performance including time,steps and error rate were recorded.In addition,,the emotional expression traits and friendship quality in the friend group were measured by corresponding scales.Results There were significant differences in time dimension between the two groups(P<0.05).Significant correlation between the operation steps and the positive dimensions of friendship quality was indicated in the friend group(P<0.05).The results also revealed that the relative changes of steps as the difficulty increased was associated with the conflict in friendship of two operators(P<0.05).Conclusion The number of steps in the initial stage of the pattern matching task could effectively predict the positive dimensions of friendship quality,while the relative change of steps with the increase of task difficulty could reflect the conflict dimension of friendship quality.

目的基于梯度设计的双人图形配对任务,探究其在友谊关系质量评估中的作用。方法招募陌生组志愿者24对(48人),朋友组40对(80人),利用改编自以往研究的双人图形配对任务,记录其任务表谊关系质量。结果在组间对比中,两组受试者在任务操作的时间维度上存在显著差异(P<0.05);在朋务难度的变化与友谊关系的冲突得分之间存在显著的相关关系(P<0.05)。结论双人图形配对任务初效反映友谊质量的冲突维度。
