목적 : 본 연구에서는 시기능훈련 전, 후의 Big5 성격(외향성, 우호성, 성실성, 신경증, 개방성)의 차이와 시기 능훈련의 향상도를 분석하였다.
방법 : 교정시력 1.0 이상의 20대 성인 남녀 42명을 대상으로 시기능훈련 전, 후의 양안시검사(포롭터CV-5000, TOPCON, JAPAN이용)와 Big5 성격검사(25문항 5점 척도)를 실시하고, 양안시 이상 분류에 따라 개인별 시기능 훈련 도구(Bernell. USA)를 선정하여 시기능훈련을 실시하였다.
결과 : Mogan’s 기준 범위내군과 범위외군의 시기능훈련 전, 후의 Big5 성격의 차이를 분석한 결과, 범위내군에서 외향성은 폭주근점(p=0.041), 융합용이성(p=0.027), -100그래디언트(p=0.048)으로 시기능훈련 전 보다 시 기능훈련 후 외향성 점수가 모두 유의하게 높게 나타났으며, 우호성은 원거리사위도(p=0.038), 원거리 음성융합버전스 회복점(p=0.010), 원거리 양성융합버전스 흐린점(p=0.027), 원거리 양성융합버전스 분리점(p=0.029), 근거 리사위도(p=0.025), 그래디언트 AC/A비(p=0.019), 융합용이성(p=0.025), 조절랙(p=0.019), 우안조절력(p=0.003), 좌안조절력(p=0.005), 양안조절용이성(p=0.012)으로 시기능훈련 전 보다 시기능훈련 후 우호성 점수가 모두 유의하게 높게 나타났다. 범위외군에서는 외향성은 –100그래디언트(p=0.048)으로 시기능훈련 전 보다 시기능훈련 후 외향성의 점수가 높게 나타났다. 우호성은 폭주근점(p=0.045), 원거리 음성융합버전스 분리점(p=0.017), 원거리 양성융합버전스 회복점(p=0.033), -100그래디언트(p=0.046), 근거리 음성융합버전스 흐린점(p=0.022), 음성 상대조절력(p=0.026), 양성상대조절력(p=0.006)으로 시기능훈련 전 보다 시기능훈련 후 우호성 점수가 모두 유 의하게 높게 나타났다.
결론 : 범위내군과 범위외군 모두 시기능훈련 전 보다 시기능훈련 후 우호성이 높아지는 것을 확인하였다.

Purpose : This study was to evaluate the effect of vision training according to Big5 personality traits (extraversion, agreeableness, conscientiousness, neuroticism, openness) by examining the difference of each personality traits before and after the vision training.
Methods : Forty-two subjects of male and female adults in their twenties, with corrected vision above 1.0, volunteered for binocular vision test and Big5 personality trait test involving 25-questionnaire with 5-point scale before and after the vision training(with a phoroptor CV-5000, TOPCON, JAPAN), where vision training was followed by selecting personalized vision training tool(Bernell. USA) based on the classification of binocular abnormality of individuals.
Results : Based on Mogan's classification, the difference of the Big5 personality traits by before and after the vision training of inner group and outer group was analyzed. As a result of analysis, as for the inner group, extraversion is based on Near point of convergence, NPC(p=0.041), Fusional facility(p=0.027), -100 Gradient(p=0.048), all the scores of extraversion were significantly higher after vision training than before the training. Agreeableness is based on lateral Phoria(far)(p=0.038), Base-in, BI vergence recovery (far)(p=0.010), Base-out, BO vergence(far) blur(p=0.027), BO vergence(far) break(p=0.029), lateral phoria (Near)(p=0.025), -1.00 Gradient phoria(p=0.019), Fusional facility(p=0.025), fused cross cylinder (p=0.019), Push-up Oculus dexter, OD(p=0.003), Push-up Oculus sinister, OS(p=0.005), Binocular accommodative facility(p=0.012), all the scores of agreeableness were significantly higher after vision training than before vision training. As for the outer group, extraversion is based on -100 Gradient (p=0.048). It is the same score with the inner group and the score of extraversion was higher after vision training than before the training. Agreeableness is based on NPC(p=0.045), BI vergence break(ar) (p=0.017), BO vergence recovery(far)(p=0.033), -1.00 Gradient phoria(p=0.046), BI vergence recovery(near) (p=0.022), NRA(p=0.026), Positive relative accommodative, PRA(p=0.006), all the scores of agreeableness were significantly higher after vision training than before the training.
Conclusion : It is assured that agreeableness about all of the inner and outer group were higher after vision training than before the training.
