Film clips are an important tool for evoking emotional responses in the laboratory. When compared with other emotionally potent visual stimuli (e.g., pictures), film clips seem to be more effective in eliciting emotions for longer periods of time at both the subjective and physiological levels. The main objective of the present study was to develop a new database of affective film clips without auditory content, based on a dimensional approach to emotional stimuli (valence, arousal and dominance). The study had three different phases: (1) the pre-selection and editing of 52 film clips (2) the self-report rating of these film clips by a sample of 113 participants and (3) psychophysiological assessment [skin conductance level (SCL) and the heart rate (HR)] on 32 volunteers. Film clips from different categories were selected to elicit emotional states from different quadrants of affective space. The results also showed that sustained exposure to the affective film clips resulted in a pattern of a SCL increase and HR deceleration in high arousal conditions (i.e., horror and erotic conditions). The resulting emotional movie database can reliably be used in research requiring the presentation of non-auditory film clips with different ratings of valence, arousal and dominance.
影片片段是在实验室中唤起情感反应的重要工具。与其他强烈的视觉刺激（例如图片）相比，影片片段在主观和生理水平上似乎更能长时间有效地引起情感。本研究的主要目的是基于情感刺激的维度方法（愉悦度、唤醒度和支配度），开发一个没有听觉内容的新的情感影片片段数据库。该研究分为三个不同阶段：（1）52 个影片片段的预选和编辑；（2）113 名参与者对这些影片片段的自我报告评分；（3）对 32 名志愿者进行生理评估[皮肤电导率水平（SCL）和心率（HR）]。选择来自不同类别的影片片段，以引发不同情感空间象限的情绪状态。结果还表明，持续暴露于情感影片片段会导致在高唤醒条件下 SCL 增加和 HR 减速的模式（即恐怖和色情条件）。由此产生的情感电影数据库可可靠地用于需要呈现具有不同愉悦度、唤醒度和支配度评分的非听觉影片片段的研究。
