摘要

精神分裂症谱系障碍(ssd)严重影响日常功能,特别是通过记忆障碍等认知缺陷。传统上归因于神经生物学因素,最近的证据强调了心理过程的作用,如脱离,它可能通过损害特征结合来破坏情景记忆的编码和检索。本研究使用虚拟现实(VR)范式来探索固态硬盘的状态脱离是否与不良刺激的特征绑定受损有关。方法选取荷兰精神卫生中心的25例SSD患者和普通人群中的25人作为研究对象。使用沉浸式虚拟现实范式,参与者导航虚拟购物中心,与3D化身互动,并识别他们的情绪面部表情。随后进行了三个记忆测试:角色身份识别(基本记忆),将角色的情感表达与角色绑定,以及将角色身份与遭遇的时间顺序绑定。状态脱离采用临床医生管理的解离状态量表(CADSS)进行测量。结果SSD组和对照组在三个特征绑定任务中没有表现出显著的性能差异。然而,在不同的小组中,结果表明,更高的状态脱离水平与更糟糕的身份-情绪绑定相对应,特别是对于愤怒的面孔。结论本研究为脱离在愤怒面孔特征结合缺陷中的作用提供了初步的实证支持。未来的研究应进一步探讨心理机制如超脱对记忆功能障碍的影响,特别是对厌恶刺激的影响。

Feature binding and detachment in psychosis: A virtual reality study

Background

Schizophrenia spectrum disorders (SSDs) significantly impact daily functioning, particularly through cognitive deficits like memory impairment. Traditionally attributed to neurobiological factors, recent evidence highlights the role of psychological processes like detachment, which may disrupt episodic memory encoding and retrieval by impairing feature binding. This study used a virtual reality (VR) paradigm to explore whether state detachment in SSDs is linked to impaired feature binding for adverse stimuli.

Methods

Twenty-five SSD patients from Dutch mental health centers and 25 individuals from the general population participated. Using an immersive VR paradigm, participants navigated a virtual shopping mall, interacted with 3D avatars, and identified their emotional facial expressions. Three memory tests followed: avatar identity recognition (basic memory), binding emotional expressions to avatars, and binding avatar identity to the encounter's temporal order. State detachment was measured using the Clinician-Administered Dissociative States Scale (CADSS).

Results

The SSD and comparison group did not display significant performance differences in any of the three feature binding tasks. However, across groups, results indicated that higher state detachment levels corresponded with worsened identity-emotion binding specifically for angry faces.

Conclusion

The present study provides tentative empirical support for the role of detachment in feature binding deficits for angry faces both in the patient and comparison group. Future studies should further explore the impact of psychological mechanisms like detachment on memory dysfunction, particularly regarding aversive stimuli.
