TY - THES A1 - Fritz, Thomas T1 - Emotion investigated with music of variable valence : neurophysiology and cultural influence T1 - Emotion untersucht mit Musik variabler Valenz : Neurophysiologie und kultureller Einfluss N2 - Music is a powerful and reliable means to stimulate the percept of both intense pleasantness and unpleasantness in the perceiver. However, everyone’s social experiences with music suggest that the same music piece may elicit a very different valence percept in different individuals. A comparison of music from different historical periods suggests that enculturation modulates the valence percept of intervals and harmonies, and thus possibly also of relatively basic feature extraction processes. Strikingly, it is still largely unknown how much the valence percept is dependent on physical properties of the stimulus and thus mediated by a universal perceptual mechanism, and how much it is dependent on cultural imprinting. The current thesis investigates the neurophysiology of the valence percept, and the modulating influence of culture on several distinguishable sub-processes of music processing, so-called functional modules of music processing, engaged in the mediation of the valence percept. N2 - Musik eignet sich besonders gut, um sowohl intensive Angenehmheit/Lust und Unangenehmheit/Unlust (siehe auch Wundt, 1896), so genannte Valenzperzepte, im Zuhörer hervorzurufen. Jedoch kann derselbe musikalische Stimulus sehr unterschiedliche Valenzperzepte in verschiedenen Zuhörern hervorrufen, was nahe legt, dass das durch Musik vermittelte Valenzperzept zumindest teilweise durch kulturelle Prägung moduliert wird. Ein Vergleich von Musik verschiedener historischer Perioden legt ebenfalls nahe, dass kulturelle Prägung das Valenzperzept des Hörers bei der Wahrnehmung von Intervallen und Harmonien moduliert. Wichtigerweise ist es nach wie vor weitgehend unbekannt, inwiefern das Valenzperzept von physikalischen Eigenschaften des Stimulus (z.B. Rauhigkeit) abhängt - und daher auf einem universellen perzeptiven Mechanismus basiert - oder wie sehr es abhängt von kultureller Prägung. Die vorliegende Dissertation untersucht die Neurophysiologie des Valenzperzepts, sowie den modulierenden Einfluss von Kultur auf mehrere funktionelle Module der Musikwahrnehmung (voneinander unterscheidbare Subprozesse der Musikwahrnehmung), die bei der Entstehung des Valenzperzepts beteiligt sind.

A1 - Fischer, Martin H. T1 - Facial Feedback Affects Perceived Intensity but Not Quality of Emotional Expressions JF - Brain Sciences N2 - Motivated by conflicting evidence in the literature, we re-assessed the role of facial feedback when detecting quantitative or qualitative changes in others’ emotional expressions. Fifty-three healthy adults observed self-paced morph sequences where the emotional facial expression either changed quantitatively (i.e., sad-to-neutral, neutral-to-sad, happy-to-neutral, neutral-to-happy) or qualitatively (i.e. from sad to happy, or from happy to sad). Observers held a pen in their own mouth to induce smiling or frowning during the detection task. When morph sequences started or ended with neutral expressions we replicated a congruency effect: Happiness was perceived longer and sooner while smiling; sadness was perceived longer and sooner while frowning. Interestingly, no such congruency effects occurred for transitions between emotional expressions. These results suggest that facial feedback is especially useful when evaluating the intensity of a facial expression, but less so when we have to recognize which emotion our counterpart is expressing.
