采用韦氏记忆测量表（WMS）及模具分别对52名精神病违法者和54名在押的正常人犯进行测量，发现两组的记忆商（MQ）、长时记忆（LTM）、短时记忆（STM）和瞬时记忆（IM）均有显著性差异（P＜0．01），说明精神病人的记忆功能有削弱。对WMS内部构成的定量分析发现MQ与STM的简单相关系数最大（r＝0．88），MQ与LTM、STM、IM均呈正偏相关，而各分量表之间均呈负偏相关，说明LTM、STM、IM是独立存在的记忆形式。通径分析说明STM对MQ的作用最大，通径系数为0．55。
Fifty-two psychiatric offenders and 54 prisoners in custody were measured by Wechsler Memory Scale (WMS) and mold respectively. It was found that the scores of MQ, LTM, STM ) And instantaneous memory (IM) were significantly different (P <0.01), indicating that mental patients have impaired memory. Quantitative analysis of the internal structure of WMS found that the simple correlation coefficient between MQ and STM was the highest (r = 0.88), MQ positively correlated with LTM, STM and IM, and all subscales showed negative partial correlation, indicating that LTM , STM, IM is an independent form of memory. Path analysis shows that STM has the greatest effect on MQ with a path coefficient of 0.55.
