A study of individual differences in coping strategies with reward frustration.

本研究旨在探讨奖赏挫折中的应对策略与前额活动之间的关系。结果表明：(1)努力-回报失衡导致的挫折感降低了双侧大脑半球背外侧前额叶皮质的反应性；(2)在挫折任务中，神经质与右侧背外侧前额叶皮质的氧合血红蛋白升高呈负相关；(3)对任务的主观集中程度与双侧大脑半球背外侧前额叶皮质的氧合血红蛋白升高呈正相关。

The present study aimed at examining the relationship between coping strategies and frontal activities in reward frustration. The results obtained suggested that (1) frustration induced by effort-reward imbalance decreased reactivitiy in the dorsolateral prefrontal cortex in both hemispheres, (2) neuroticism negatively correlated with oxy-Hb increases in the right dorsolateral prefrontal cortex during the frustration task, (3) subjective degree of concentration to the task positively correlated with oxy-Hb increases in the dorsolateral prefrontal cortex in both hemispheres.
