    How do sound and color features affect self-report emotional experience in response to film clips?
    Iyilikci, EA; Demirel, A; Isik, F; Iyilikci, O
    Previous research has shown that the use of short film clips is one of the most successful and widely-used methods of emotion elicitation. Nevertheless, there is a high degree of audiovisual variation across film clips, resulting in a trade-off in terms of controllability. To address this complexity, the present study aimed to investigate the potential effects of sound and color on film clips' emotion-elicitation levels. For this purpose, four different film clips were selected for each of the eight emotion categories: amusement, tenderness, calmness, anger, sadness, disgust, fear, and neutrality. All film clips were manipulated in terms of features of sound (sound versus silent) x color (color versus BW). In total, 128 film clips were tested online on various parameters: intensity of target emotion, valence, arousal, discreteness, and non-target emotions. The results revealed that sound was a mild contributing factor in increasing the degree of target emotions and evoking less boredom and more interest. However, color effects were less pronounced in emotion-elicitation using film clips. Furthermore, the study provided preliminary evidence that for most of the film clips, there was no significant difference in emotional reactivity in response to subtitled versus dubbed film clips. In conclusion, the current study showed that film clips (with a few exceptions) can evoke moderate to high levels of emotions independent of their bottom-up features, such as sound or color.

    An extended emotion-eliciting film clips set (EGEFILM): assessment of emotion ratings for 104 film clips in a Turkish sample
    Iyilikci, EA; Boga, M; Yüvrük, E; Özkiliç, Y; Iyilikci, O; Amado, S
    The primary aim of this study was to test emotion-elicitation levels of widely used film clips in a Turkish sample and to expand existing databases by adding several new film clips with the capacity to elicit a wide range of emotions, including a rarely studied emotion category, i.e., calmness. For this purpose, we conducted a comprehensive review of prior studies and collected a large number of new suggestions from a Turkish sample to select film clips for eight emotion categories: amusement, tenderness, calmness, anger, sadness, disgust, fear, and neutrality. Furthermore, we aimed to assess emotion-eliciting levels of short video clips, mostly taken by amateur video footage. In total, 104 film clips were tested online by rating several affective dimensions. Self-reported emotional experience was assessed in terms of intensity, discreteness, valence, and arousal. It was found that at least one of the existing film clips, most of the new film clips, and the short video clips were successful at eliciting medium to high levels of target emotions. However, we also observed overlaps between certain emotions (e.g., tenderness-sadness, anger-sadness-disgust, or fear-anxiety). The current results are mostly in line with previous databases, suggesting that film clips are efficient at eliciting a wide range of emotions where cultural background might play a role in the elicitation of certain emotions (e.g., amusement, anger, etc.). We hope that this extended emotion-eliciting film clips set (EGEFILM) will provide a rich resource for future emotion research both in Turkey and the international area.

    Ways of processing semantic information during different change detection tasks
    Türkan, BN; Iyilikci, O; Amado, S
    Recent research on change blindness phenomenon revealed contradictory findings about scene-object relationship. These discrepant results might be stemming from procedure and task constraints. Therefore, we aimed to investigate the effect of the type of paradigm on change blindness phenomenon during the natural scene viewing in the frame of high-level scene perception. For this purpose, we compared two frequently used change detection tasks; flicker and one-shot paradigms. Additionally, eye movements were recorded to investigate the active attention mechanisms during the change detection performance. Our results suggested that change detection performance and eye movements varied across the different paradigms. We interpreted this result as the influence of different stimuli exposures and different interruptions on processing of visual stimuli during the detection of change. We explained the inconsistent results revealed by the previous research in terms of attention mechanisms, namely attention attraction and attention disengagement that might differ while performing the different change detection tasks.
