Abstract
The current study aims to compare the word recognition performance and the confidence of the memory in the high and low obsessive compulsive Symptom Subjects (Ss). 12 high obsessive compulsive Symptom (HOC) Ss and 12 low obsessive compulsive Symptom (LOC) Ss responded to a words recognition task, which totally has 60 obsessive compulsive sensitive words (OCSW), 60 emotional sensitive words (ESW) and 60 neutral words (NW). The results indicate that, compared to LOC group, HOC group have relatively poorer memory on OCSW (t(22) = –2.161, p = 0.042), because they judged more new words as learned (t (22) = 1.832, p = 0.081). Particularly on the basis of signal detection analysis for the neutral words, the HOC Ss tend to have the lower d’ than the LOC Ss (t (22) = –2.037, p = 0.054). And the interaction of memory confidence between the groups and words types was significant (F (1,22) = 4.60, p < 0.05). The results of the present study implicate that the disability to determine confound information is one of the causes for lower confidence of HOC Ss, but this relationship merits further study.
