情绪识别障碍是精神分裂症（SZ）的核心特征，存在于该疾病的所有阶段，并导致不良的社交结果。然而，引起这种缺陷的潜在机制尚未阐明，因此，很难制定精确有针对性的干预措施。证据支持使用旨在改变SZ个体视觉注意模式的方法，以实现有意义的社会认知改善。然而，到目前为止，注意力塑造系统还没有充分利用现有的技术（如眼动追踪）来实现这一目标。目前的工作包括一种名为MASI-VR的新型注视敏感社会技能干预系统的设计和可行性测试。在基线评估中，对确诊为SZ的门诊成人（n= 10）和神经正常参与者（n= 10）的情绪识别和视觉注意力进行评估，并在三周内进行五次培训后对SZ样本进行干预系统的先导测试。与<？enlrg 5 pt ?与神经正常的同龄人相比，SZ组的参与者对表现中等强度恐惧的面孔表现出较低的识别能力，花更多的时间考虑所呈现的情绪，并且更少的注视。此外，SZ组的参与者在训练后对恐惧面孔的识别方面表现出显著的改善。初步证据支持在SZ个体情绪识别和社会注意的评估和训练中使用注视敏感范式的可行性，因此需要进一步评估这种新的干预措施。
Emotion recognition impairment is a core feature of schizophrenia (SZ), present throughout all stages of this condition, and leads to poor social outcome. However, the underlying mechanisms that give rise to such deficits have not been elucidated and hence, it has been difficult to develop precisely targeted interventions. Evidence supports the use of methods designed to modify patterns of visual attention in individuals with SZ in order to effect meaningful improvements in social cognition. To date, however, attention-shaping systems have not fully utilized available technology (e.g., eye tracking) to achieve this goal. The current work consisted of the design and feasibility testing of a novel gaze-sensitive social skills intervention system called MASI-VR. Adults from an outpatient clinic with confirmed SZ diagnosis (n= 10) and a comparison sample of neurotypical participants (n= 10) were evaluated on measures of emotion recognition and visual attention at baseline assessment, and a pilot test of the intervention system was evaluated on the SZ sample following five training sessions over three weeks. Consistent with the<?enlrg 5pt?> literature, participants in the SZ group demonstrated lower recognition of faces showing medium intensity fear, spent more time deliberating about presented emotions, and had fewer fixations in comparison to neurotypical peers. Furthermore, participants in the SZ group showed significant improvement in the recognition of fearful faces post-training. Preliminary evidence supports the feasibility of a gaze-sensitive paradigm for use in assessment and training of emotion recognition and social attention in individuals with SZ, thus warranting further evaluation of the novel intervention.
