概括

精神分裂症患者在判断面部可信度或瞳孔反应性方面与对照人群没有区别. 然而,患者的瞳孔变化与积极的症状和偏执有关,这表明与症状严重程度的潜在联系.

科学领域:

神经科学是一个神经科学.
精神病学是一个精神病学.
社会认知是指社会认知.

背景情况:

精神分裂症患者通常在处理社会线索方面表现出困难.
异常的社会暗示处理可能会导致精神分裂症的社会缺陷.

研究的目的:

为了比较精神分裂症患者和健康对照者之间的可信度评级和瞳孔反应性.
调查可信度判断,学生反应性和精神分裂症症状严重程度 (偏执) 之间的关系.
探索精神分裂症中的社会认知偏见和瞳孔反应.

主要方法:

精神分裂症谱系障碍患者 (N=48) 和健康对照组 (N=33) 完成了一项可靠性任务,用于眼睛跟踪学生尺寸测量.
瞳孔大小是在中性面孔的呈现过程中测量.
使用社区心理功能评估 (CAPE-42) 和简要精神病学评分表 (BPRS) 评估症状严重程度.

主要成果:

在可信度评级或学生反应性方面没有观察到任何显著的群体差异.
在患者中,瞳孔尺寸变化 (绝对差异,扩张) 与积极的症状和自我报告的偏执症相关.
这些发现表明,稳定的精神分裂症门诊患者在可信度方面没有社会认知偏见,学生反应性在这些判断中也没有直接作用.

结论:

这项研究没有发现可信度判断中的社会认知偏差或在稳定的精神分裂症门诊患者中在此类判断期间改变学生反应性的证据.
瞳孔反应性变化与患者的积极症状和偏执症有关,需要进一步调查.
未来的研究应该考虑更长的刺激呈现,对抗精神病药物的控制,并包括更大,更有症状的患者群体.

关键词:

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Stereotype Threat and Self-fulfilling Prophecies

Stereotype Threat and Self-fulfilling Prophecies

When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...
