Arga röster ökar muskelanspänningen / Angry voices increase muscle tension

Gustafsson, Karin January 2012 (has links)
Syftet var att undersöka om exponering inför emotionella röster påverkar muskelanspänning och hjärtats slagfrekvens samt om det finns en samvariation mellan storlek eller längd på muskelanspänning vid aversiv emotionell input och grad av alexitymi. 24 studenter lyssnade på arga, glada och neutrala röster samtidigt som muskelanspänning mättes med EMG och hjärtats slagfrekvens med EKG. Grad av alexitymi mättes med Toronto Alexithymia Scale 20. Resultaten visade att arg eller glad röststimuli gav större muskelanspänningen än neutralröststimuli. Ingen skillnad i muskelanspänning fanns mellan arg eller glad röst. Det fanns inget samband mellan storlek eller längd på muskelanspänning och grad av alexitymi. / The object was to investigate whether exposure to emotionally valid voices, affect muscle tension and heart rate, and if there is a correlation between size or length of muscle tension during aversive emotional input and degree of Alexithymia. 24 students listened to angry, happy and neutral voices while muscle tension was measured by EMG and heart rate by EKG. Degree of Alexithymia was measured by Toronto Alexithymia Scale 20. The results showed that angry or happy voice stimuli caused higher muscle tension than neutral voice stimuli. No difference in muscle tension was shown between angry and happy voice. There was no correlation between size or length of muscle tension and degree of Alexithymia.
