Abstract
In this study, we focused on domain-specific emotions and investigated the characteristics of the emotions evoked in the individual voluntary manufacture and the characteristics of the manufacture itself. In study 1, we specified the individual manufactures on which we conducted this study. In study 2, we conducted interviews based on the Evaluation Grid Method and extracted 10 positive emotions and 12 negative emotions that were evoked during individual manufacture. In study 3, we investigated the characteristics of the emotions along a valence axis and an arousal axis based on the core affect mode. These emotions had strong positive correlations between their valence and arousal. This correlation indicates the feedback functions of the emotions: the acceleratory function of positive emotions and the inhibitory function of the negative emotions. In addition, we divided these emotions into four clusters and found different patterns of evocation in the categories of manufacture and timing of the manufacture between clusters, which suggests the presence of qualitative differences.
