疼痛敏感性影响时间注意

Pain Sensitivity Affects Temporal Attention

目的:探究疼痛敏感性对时间注意的影响。方法:招募48名被试,使用时间线索范式,采用3 (图片类型:无图片、中性图片、疼痛图片) ×2 (线索类型:有效和中性) ×2 (时间间隔:短时和长时)被试内设计,收集行为数据。结果:1) 呈现三种图片类型时,时间线索效应在短时间隔中均稳定存在;2) 时间线索效应大小会被图片认知加工干扰;3) 高疼痛敏感组在疼痛图片呈现时,能够维持短时间隔的时间线索效应。4) 低疼痛敏感组中存在疼痛图片评分与短时间隔的时间线索效应大小的显著正相关。结论:疼痛敏感性影响时间注意,较高疼痛敏感性能够在一定程度上改善因图片认知加工而削弱的时间线索效应。疼痛感受在一定程度上能够帮助个体更好地适应环境。

Objective: To explore the effect of pain sensitivity on temporal attention. Methods: 48 subjects were recruited to collect behavioral data in a 3 (picture type: no picture, neutral picture, pain picture) ×2 (cue type: valid and neutral) ×2 (time interval: short and long) in-subject design using temporal cueing paradigm. Results: 1) The temporal cueing effect of the three picture types was stable in the short interval;2) The temporal cueing effect was affected by the picture cognitive processing. 3) The high pain sensitivity group could maintain a temporal cueing effect at a short interval when the pain picture was presented. 4) There was a significant positive correlation between pain picture score and temporal cueing effect at a short interval in the low pain sensitivity group. Conclusion: Pain sensitivity affects temporal attention. Higher pain sensitivity can improve the temporal cueing effect weakened by the cognitive processing of pictures. To some extent, pain perception can help individuals better adapt to the environment.
