妄想型精神分裂症與靑春型精神分裂症患者之三段論證與經驗推論

SYLLOGISTIC REASONING AND PRAGMATIC INFERENCE IN SCHIZOPHRENICS

本研究旨在分别探討妄想型與靑春型精神分裂症患者之邏輯推理能力經驗推論的怪異性。以三段論證測量邏輯推理歷的結果發現，妄想型與靑春型精神分裂症患者各與其正常配對組的(1)反應正確率無差異存在。(2)推理策略同受氣氛效果之支配。(3)反應潛伏期亦無差異存在，但二類患者均有較長的潛伏期，顯示有注意力缺陷。另要求受試者針對刺激材料，就其經驗加以推論，結果發現妄想型與靑春型精神分裂症患者各與其正常配對組的(1)反應普遍性有顯著差異，二類患者的反應普遍性較低，比較怪異。(2)反應潛伏期有顯著差異，二類患者的反應潛伏期均較長。

The present study investigated differential manifestafions of logical inference and pragmatic inference in paranoid and hebephrenic schizophrenics. The performance of syllogistic reasoning was not significantly different from their normal controls. Both types of schizophrenia took longer to respond and produced more bizarre responses than their normal controls in pragmatic inference. It is suggested that strange and bizarre inference is characteristic in paranoid and hebephrenic schizophrenics.
