dc.description.abstract文獻上指出,左撇子(左利),以及家族性左利都是影響語言側化的因素。軀體特異性假設(body-specificity hypothesis) (Casasanto, 2009) 指出,人們較易將慣用手側與正向 概念聯結在一起。本研究旨在探討情緒詞處理是否也能在此軀體特異性假設上得到驗證。 實驗採用分視野實驗典範,實驗刺激為中文雙字詞,有三個水準:正向情緒詞、中性詞, 及負向情緒詞。受試者則招募了左手慣用者、有家族左撇的右手慣用者以及無家族左撇 的右手慣用者,每組受試者約三十人。本實驗假設,當正面詞彙呈現在與慣用手同側的 視野時,受試者反應速度較快。實驗結果沒有支持軀體特異性假設,但是三組受試者於 作答精確度以及反應速度上皆呈現了字詞辨識文獻中常觀察到的右視野優勢。實驗結果 也觀察到顯著的效價效果(valence effect),亦即受試者對於正面詞作答反應最快,負面 詞次之,中性詞速度最慢。此外,比較左右視野的情緒詞作答精確度,發現只有左視野 /右腦的情緒詞(正面詞或負面詞)對比中性詞有顯著精確度差異,右視野/左腦則無此 情緒效果,此結果呼應了常現於情緒處理文獻的左視野/右腦優勢。最後,比較三組受 試者,我們觀察到左撇子組別的詞彙表徵較為雙側化,此發現也與現存的左利與語言半 腦優勢文獻不謀而合。zh_TW
dc.description.abstractLeft-handedness, as well as familial sinistrality (FS), has been shown to influence the language lateralization. According to the body-specificity hypothesis, people tend to associate their dominant side of space with positive ideas than the contrary sides. The current study aimed to investigate whether the body-specificity hypothesis extended to emotion word processing. A divided visual field paradigm was employed, and the experimental materials were bisyllabic Chinese words manipulated by valence at three levels (positive, neutral, negative). Participants were also specifically recruited, with roughly 30 individuals in the left-handed group, FS+ group and FS- group respectively. It was hypothesized that shorter RTs might be observed when the positive words were presented to the visual field ipsilateral to one’s dominant hand. The results of the current study did not support the body-specificity hypothesis. However, our data showed a robust RVF advantage on both accuracy rates and RTs in all three subject groups commonly reported in studies on word recognition. The data also revealed significant valence effect, with positive stimuli being most swiftly responded to, negative stimuli longer RTs, and neutral words longest RTs. Moreover, it was found when comparing the two visual fields that only LVF/RH, but no RVF/LH, exhibited accuracy contrasts between valenced words and neutral words, which echoed the LVF/RH advantage commonly reported in emotion processing studies. Last but not least, with the comparisons between visual fields across three groups, we also observed a somewhat bilateral lexical representation in the left-handed group, which joins the existing literature on the investigation of handedness and language dominance.en_US
