Abstract

Despite widespread implementation of psychodrama, no empirical studies investigated neural mechanisms of its techniques. One gap lies in the sociocognitive model of role reversal (RR) which posits three processes: empathic role-taking, behavioural reproduction and role feedback. Related studies found deactivations in prefrontal cortex (PFC) during acting tasks, implicating inhibited self-related cognition. However, contrasting studies found PFC activations during role-taking, citing blurred boundaries between self and other that is characteristic of empathy. This study employs fNIRS to uncover neurophysiological correlates of the three processes. Three conditions (Naturalistic Conversation - NC, Role-Play - RP, Role Reversal - RR) were designed to introduce empathic role-taking and behavioural reproduction, and role feedback in transitions from NC to RP, and RP to RR respectively. 41 non-clinical adult dyads underwent all conditions. First-level General Linear Model from fNIRS signals was based on participants’ role-related utterances and compared across conditions. Anterior left PFC activity decreased as participants produced role-related utterances during RP compared to NC, implying lowered recruitment of self-referential networks during empathic role-taking and behavioural reproduction, partially supporting patterns of brain activation that can be mapped to specific sociocognitive processes in RR. Findings partially support the involvement of self-referential networks in specific sociocognitive processes in RR.

角色扮演过程中左前额皮质激活减少:心理剧社会认知模型的近红外光谱研究
尽管心理剧被广泛使用,但没有实证研究调查其技术的神经机制。角色逆转的社会认知模型提出了共情角色扮演、行为复制和角色反馈三个过程。相关研究发现,在执行任务时,前额叶皮层(PFC)失活,这意味着自我相关认知受到抑制。然而,对比研究发现,PFC在角色扮演过程中被激活,并指出自我与他人之间的界限模糊是移情的特征。本研究使用近红外光谱来揭示这三个过程的神经生理学相关性。设计了三个条件(自然对话- NC、角色扮演- RP、角色逆转- RR),分别引入共情角色扮演和行为复制,以及从NC到RP和RP到RR转换中的角色反馈。41名非临床成年夫妇接受了所有条件。基于fNIRS信号的一级一般线性模型基于参与者的角色相关话语,并在不同条件下进行比较。与NC相比,参与者在RP过程中产生与角色相关的话语时,左前PFC活动减少,这意味着在共情角色扮演和行为复制过程中,自我参照网络的招募减少,这部分支持了可以映射到RR中特定社会认知过程的大脑激活模式。研究结果部分支持自我参照网络参与RR的特定社会认知过程。

期刊介绍: The Arts in Psychotherapy is a dynamic, contemporary journal publishing evidence-based research, expert opinion, theoretical positions, and case material on a wide range of topics intersecting the fields of mental health and creative arts therapies. It is an international peer-reviewed journal publishing 5 issues annually. Papers are welcomed from researchers and practitioners in the fields of art, dance/movement, drama, music, and poetry psychotherapy, as well as expressive and creative arts therapy, neuroscience, psychiatry, education, allied health, and psychology that aim to engage high level theoretical concepts with the rigor of professional practice. The journal welcomes contributions that present new and emergent knowledge about the role of the arts in healthcare, and engage a critical discourse relevant to an international readership that can inform the development of new services and the refinement of existing policies and practices. There is no restriction on research methods and review papers are welcome. From time to time the journal publishes special issues on topics warranting a distinctive focus relevant to the stated goals and scope of the publication.
