Recent evidence suggests that schizophrenia is associated with impaired processing of global visual motion, but intact processing of global visual form. This project assessed whether preserved visual form detection in schizophrenia extended beyond low-level pattern discrimination to a naturalistic form-detection task. We assessed both naturalistic form detection and global motion detection in individuals with schizophrenia spectrum disorder, bipolar affective disorder, and healthy controls. Individuals with schizophrenia spectrum disorder and bipolar affective disorder were impaired relative to healthy controls on the global motion task, but not the naturalistic form-detection task. Results indicate that preservation of visual form detection in these disorders extends beyond configural forms to naturalistic object processing.
近期证据表明，精神分裂症与整体视觉运动处理受损有关，但整体视觉形式处理完好。本项目评估了精神分裂症患者保留的视觉形式检测能力是否不仅限于低级模式辨别，还能扩展到自然主义形式检测任务。我们评估了精神分裂症谱系障碍、双相情感障碍患者以及健康对照者的自然主义形式检测和整体运动检测。在整体运动任务中，精神分裂症谱系障碍和双相情感障碍患者相对于健康对照者表现受损，但在自然主义形式检测任务中则不然。结果表明，这些疾病中视觉形式检测的保留不仅限于构型形式，还扩展到自然主义物体处理。
