- It has been the matter of much debate whether perceivers are able to distinguish spontaneous vocal expressions of emotion from posed vocal expressions (e.g., emotion portrayals). In this experiment, we show that such discrimination can be manifested in the autonomic arousal of listeners during implicit processing of vocal emotions. Participants (N = 21, age: 20-55 years) listened to two consecutive blocks of brief voice clips and judged the gender of the speaker in each clip, while we recorded three measures of sympathetic arousal of the autonomic nervous system (skin conductance level, mean arterial blood pressure, pulse rate). Unbeknownst to the listeners, the blocks consisted of two types of emotional speech: spontaneous and posed clips. As predicted, spontaneous clips yielded higher arousal levels than posed clips, suggesting that listeners implicitly distinguished between the two kinds of expression, even in the absence of any requirement to retrieve emotional information from the voice. We discuss the results with regard to theories of emotional contagion and the use of posed stimuli in studies of emotions.

- Research on group creativity needs to develop methods that capture data at a group level in different ways. This pilot study uses newly validated tools in an experimental design and primary statistical processing and analysis of data in order to investigate whether the design and the tools are appropriate for a full-scale experiment. The psychological experience called Flow is operationalized as an expression of creativity at the group level (Team flow) that may occur during the performance of challenging activities in which all participating team members are completely involved in their common activity, and are working together intuitively and synergistically towards the common purpose and enhance team’s effectiveness, productivity and performance. This paper focuses on team members’ motivation and learning, engagement, concentration, experience of synchronization and coordination during a group based problem solving task and also test how these dimensions of the group flow experiences relates to individual state flow experiences.

- To what extent do childhood experiences of music practice influence thinking about music later in life? In this contribution, 27–54-year-old monozygotic twins discordant with regard to piano playing in life were interviewed about music experiences during childhood and adult years. Recordings of heart rate variability were performed continuously during the interviews which were done separately with playing and nonplaying cotwins. Random factors had determined whether the twin chose to play or not. The rationale behind using monozygotic twins was that this offered a possibility to account totally for genetic influence. The physiological recordings in general showed small intrapair differences. However, during the initial discussion about how the difference arose in piano practice during childhood, the nonplaying twin used more time and showed evidence of a stronger sympathetic activation than the cotwin. These findings are discussed against the background of music's importance in childhood.
