| Summary: | 碩士 === 輔仁大學 === 臨床心理學系碩士班 === 102 === Background and purpose: According to the fully dimensional model (Claridge, 1997) based on Eysenck and Eysenck’s personality theory (1976), discontinuity in function distinguishes psychological health from abnormalities or disease. Past research demonstrates that non-clinical individuals with high levels of schizotypal traits perform poorly across some of the same domains found to be impaired in individuals diagnosed with schizophrenia, namely, deficits in antisaccade, (O’ Driscoll et al., 1998), deficits in experiencing and processing emotions (Kerns, 2005), and difficulties in determining the emotions of others through social contextual cues (Miller & Lenzenweger, 2012). These vulnerabilities contribute to the development of schizophrenia related disorders. However, the relationships between these factors and how they affect the processing of emotional information had yet to be clarified. This study thus investigated the antisaccade deficits and emotional processing of high and low schizotypic individuals, examining the relationships among these vulnerabilities through the inclusion of emotion-related materials. Method: 135 participants completed the Schizotypal Personality Questionnaire (SPQ), the Launay-Slade Hallucination Scale(LSHS), Multiple emotion checklist, Multiple emotional experience checklist, the State-Trait Anxiety Inventory-Trait (STAI-T), the saccade task, and the social- emotion judgment task from which two groups were identified, 25 each based on the highest and lowest SPQ scores (Hereon identified as HS and LS). Results: (1) In the mixed saccade task, the HS group presented more difficulties in engaging attention on target with fear, but better in inhibiting; (2) According to subjective accounts, the HS group experienced more negative emotions and negative events than the LS group; (3) In the social-emotion judgment task, the HS group fixated more on displays of fear than the LS group; (4) Schizotypal traits correlated with saccadic attention, emotional experiences and eye movement indicators in social contexts, which effectively constructs a multiple regression model. Discussion: Across these results, compare to LS, we discovered that target with fear would influence eye movement pattern in HS and they frequently felt fear. This differed from the past research (Green, Williams, & Davidson, 2001), suggesting further study to clarify the meaning of fear in HS.
