INTRODUCTION
There is currently substantial literature to suggest that patients with schizophrenia are impaired on many face-processing tasks. This study investigated the specific effects of configural changes on face recognition in groups of schizophrenia patients.
METHODS
In Experiment 1, participants identified facial expressions in upright faces and in faces inverted from their upright orientation. Experiments 2 and 3 examined recognition memory for faces and other non-face objects presented in upright and inverted orientations. Experiment 4 explored recognition of facial identity in composite images where the top half of one face was fused to the bottom half of another face to form a new face configuration.
RESULTS
In each experiment, the configural change had the same effect on face recognition for the schizophenia patients as it did for control participants. Recognising inverted faces was more difficult than recognising upright faces, with a disproportionate effect of inversion on faces relative to other objects. Recognition of facial identity in face-halves was interfered with by the formation of a new face configuration.
CONCLUSION
Collectively, these results suggest that people with schizophrenia rely on configural information to recognise photographs of faces.
引言
目前有大量文献表明，精神分裂症患者在许多面部处理任务上存在缺陷。本研究调查了构型变化对精神分裂症患者组面部识别的具体影响。
方法
在实验1中，参与者识别正立面孔和从正立方向倒置的面孔中的面部表情。实验2和实验3检验了对正立和倒置呈现的面孔及其他非面孔物体的识别记忆。实验4探索了在合成图像中对面部身份的识别，其中一张脸的上半部分与另一张脸的下半部分融合形成新的面部构型。
结果
在每个实验中，构型变化对精神分裂症患者面部识别的影响与对对照组参与者的影响相同。识别倒置面孔比识别正立面孔更困难，相对于其他物体，倒置对面孔的影响不成比例。新面部构型的形成干扰了对面孔两半部分中面部身份的识别。
结论
总体而言，这些结果表明，精神分裂症患者依靠构型信息来识别面部照片。
