We communicate emotions in a multimodal way, yet non-verbal emotion communication is a relatively understudied area of research. In three experiments, we investigated the role of gesture characteristics (e.g., type, size in space) on individuals’ processing of emotional content. In Experiment 1, participants were asked to rate the emotional intensity of emotional narratives from the videoclips either with iconic or beat gestures. Participants in the iconic gesture condition rated the emotional intensity higher than participants in the beat gesture condition. In Experiment 2, the size of gestures and its interaction with gesture type were investigated in a within-subjects design. Participants again rated the emotional intensity of emotional narratives from the videoclips. Although individuals overall rated narrow gestures more emotionally intense than wider gestures, no effects of gesture type, or gesture size and type interaction were found. Experiment 3 was conducted to check whether findings of Experiment 2 were due to viewing gestures in all videoclips. We compared the gesture and no gesture (i.e., speech only) conditions and showed that there was not a difference between them on emotional ratings. However, we could not replicate the findings related to gesture size of Experiment 2. Overall, these findings indicate the importance of examining gesture’s role in emotional contexts and that different gesture characteristics such as size of gestures can be considered in nonverbal communication.
