【摘要】： 大量犯罪學、經濟學以及心理學的研究表明,沖動性行為決策是罪犯的核心特征。目前有關人類沖動性行為決策的研究已形成了基于軀體標記假設的賭博實驗范式(Iowa Gambling Task, IGT)和基于行為經濟學的延遲折扣實驗范式(Delay Discounting Task, DDT)兩種研究取向。然而,很少有研究基于這兩種范式考察罪犯的沖動性行為決策模式。 本研究采用跨范式的研究策略,考察了暴力型罪犯和毒品型罪犯對風險決策及延遲強化的反應模式,對于探索暴力型罪犯和毒品型罪犯行為沖動性的結構特征具有重要的理論意義。同時,本研究對于完善和發(fā)展罪犯沖動性行為決策的實驗室評定指標,指導針對該類人群的臨床治療及實踐也具有顯著的實際應用價值。 本研究包括兩個實驗,分別考察了暴力型罪犯和毒品型罪犯的風險決策情境和延遲強化情境中的沖動性行為反應模式。研究獲得以下主要結論： (1)暴力組和毒品組被試在收益-風險并存情境中的決策功能缺失主要表現為“即時收益優(yōu)先”的選擇模式及對風險的耐受性特征,并由此導致了其不良的決策績效及決策策略改變緩慢等決策后果； (2)暴力組和毒品組被試在延遲強化情境中存在決策功能缺失,主要表現為對即時獎賞的超敏感性及對延遲價值的非敏感性,導致其對長遠價值的快速折扣； (3)在延遲強化情境中,相對于正常人群,暴力組和毒品組被試對延遲強化物的折扣速度更快,其對金錢延遲強化更不能等待,但暴力組被試折扣速度最快,毒品組被試次之；
[Abstract]:A large number of criminological, economic and psychological studies show that impulsive behavior decision-making is the core feature of criminals. At present, the research on human impulsive behavior decision has formed two research orientations: Iowa Gambling Task (IGT) based on somatic markers hypothesis and delay discounting Task (DDT) paradigm based on behavioral economics. However, few studies based on these two paradigms are used to investigate the impulsive behavior decision patterns of criminals. In this study, a cross-paradigm approach was used to investigate the response patterns of violent and drug-type criminals to risk decision making and delayed reinforcement. It is of great theoretical significance to explore the structural characteristics of violent criminals and drug criminals. At the same time, this study has significant practical application value for perfecting and developing the laboratory evaluation index of criminal impulsive behavior decision and guiding the clinical treatment and practice for this kind of people. Two experiments were conducted to investigate the risk decision-making and impulsive behavior patterns of violent criminals and drug offenders respectively. The main conclusions of the study are as follows: (1) the lack of decision-making function of the subjects in both the violence group and the drug group in the revenue-risk co-existing situation is mainly manifested in the "immediate benefit first" choice pattern and the tolerance to risk. As a result, the poor decision performance and the slow change of decision-making strategies resulted in the decision consequences. (2) there was a lack of decision-making function in the delayed reinforcement situation of the subjects in the violence group and the drug group. It is mainly shown by its hypersensitivity to instant reward and its insensitivity to delayed value, which leads to rapid discounting of long-term value. (3) in delayed reinforcement situation, compared with the normal population, The discount rate of delayed fortification was faster in the violence group and drug group, but the discount speed was the fastest in the violence group, followed by the drug group.
