【摘要】：采用跨期选择任务考察了积极、中性、消极情绪效价的预期想象对高、低冲动者的延迟折扣的改变机制.结果发现:(1)总体而言,积极预期想象显著降低了被试的延迟折扣,消极预期想象显著增加了被试的延迟折扣,而中性预期想象对延迟折扣则没有明显影响;(2)具体而言,积极预期想象明显降低了高、低冲动性2组被试的延迟折扣,但消极预期想象只显著增加了高冲动组的延迟折扣,对低冲动组的影响则不显著.结果支持了"情境预期-情绪假说"理论,即预期想象通过预期情绪调节延迟折扣改变的方向;消极预期想象显著增加了高冲动组的延迟折扣而对低冲动组没有明显影响,可能是低冲动组具有更好的自我控制能力.
[Abstract]:Intertemporal selection tasks were used to investigate the change mechanism of the expectation imagination of positive, neutral and negative emotion titer to the high and low impulsive people.The results showed that: (1) overall, the positive expectation imagination significantly reduced the delayed discount, while the negative expectation imagination significantly increased the delayed discount, while the neutral expectation imagination had no significant effect on the delay discount.The positive expectation imagination significantly decreased the delay discount of the two groups, but the negative expectation imagination only increased the delay discount of the high impulse group, but the effect on the low impulse group was not significant.The results support the theory of "situational anticipation-emotion hypothesis", that is, anticipatory imagination adjusts the direction of delay discount by anticipating emotion, and negative anticipatory imagination increases the delay discount of high impulsive group, but has no obvious effect on low impulse group.It may be that the low-impulse group has better self-control.
