The effect of cognitive involvement on aesthetic preference and emotion in art appreciation

藝術欣賞二階段模型所發現的第二階段美感提升現象，若根據流暢性理論加以解釋，為單純曝光造成流暢性提升而導致的結果，未涉及認知處理歷程的影響，然而情緒評估理論以及Leder等人（2004）的美感經驗與評價歷程神經模型，都強調美感經驗為認知與情感的交互作用。針對上述兩類不同的理論觀點，本研究的目的在於探討認知涉入在美感歷程中的重要性，同時亦嘗試瞭解美感經驗中認知與情緒的關係。本研究讓參與者欣賞不同時代、流派與國家的具象藝術畫作，共分成三個實驗。實驗一收集美感相關情緒詞彙，發展美感情緒量表；實驗二與實驗三延伸Locher等人（2007）之實驗設計，分別收集美感偏好與美感情緒的資料，包含顯性與隱性指標，欲從美感提升現象中檢驗認知涉入對兩種美感歷程產物的影響力。實驗二關心美感偏好隨時間的變化，結果顯示認知涉入有助於偏好的提升，而隱性偏好亦有相似的趨勢；實驗三則發現美感情緒並沒有隨呈現時間增加而提升，而認知涉入的影響力也較不明顯，臉部EMG測量則未能反映出隱性美感情緒。本研究也發現，國畫較西畫更顯著地出現美感偏好或情緒的提升現象且較受認知涉入影響，此外，主觀偏好與不偏好的西畫在美感偏好與正向情緒類別之結果中，皆有類似適應的效果，其中主觀偏好畫作隨時間增長而正向情緒減少、負向情緒增加。綜合而言，本研究結果支持認知涉入為美感偏好提升之要素，但是無法確認認知與情緒兩者之間的互動關係，此外，藝術欣賞的第二階段不只有美感提升的現象，亦有美感下降的現象。The increase of aesthetic preference over viewing time was found in the study of the two-stage model of art appreciation. This phenomenon could be interpreted by mere exposure effect on improvement of fluency, not involving the influence from the cognitive processes. However, some theories (Silvia, 2011; Leder et al., 2004) emphasized the interaction between cognition and emotion in aesthetic experience. Based on these two kinds of theoretical perspective, the purpose of this study is to explore the role of cognitive involvement in aesthetic processes, and to understand the relationship between cognition and emotion in aesthetic experience. There are three experiments in this study, using the figurative art paintings from different era, genre and countries as the material. In Experiment 1, the emotional adjectives were collected to develop the scale of aesthetic emotion. In Experiment 2 and 3, the effects of cognitive involvement on aesthetic preference and emotion were tested, respectively. We extended the experiment design from Locher et al. (2007) to manipulate the degree of cognitive involvement additionally, with both the explicit and implicit indexes measured. Overall, the results showed that cognitive involvement helped the increase of preference, but not of emotion, because there was no increase of emotion founded. In addition, the effect of cognitive involvement in Chinese paintings was more obvious than that in West paintings. We also found that there could be adaptation effect in aesthetic process. In conclusion, the importance of cognitive involvement in preference increase was supported. But we cannot confirm the interaction between cognition and emotion. In addition, not only the increase of aesthetic preference and emotion, but also the decrease of them could be found in the second stage of art appreciation
