| Research Abstract |
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.
