Before presenting the qualitative methods and techniques applied in the empirical project, it is useful to provide an overview of frequently applied emotion measurement methods and their limitations regarding this study. Given the paucity of emotion research in mergers and acquisitions, appropriate measurement tools are not readily available. A qualitative tool was therefore developed to capture emotions in this work. This allowed summarizing and comparing the emotional experiences of respondents. 6.1 WHICH APPROACHES TO EMOTION MEASUREMENT HAVE BEEN USED IN PAST STUDIES? Emotions are complex phenoma which are not easy to measure. They take place inside the individual, but they can trigger signals that are visible from outside. Debate is continuing among emotion researchers about how far these signals can be interpreted pursuing an outsider perspective and in which particular way this could be done. Emotions have a physiological, an expressive and an individual experience component (Öhman, 1986).1 Measurement methods correspondingly concentrate on techniques which (a) are able to quantify corporeal reactions, (b) help to analyse displayed emotions of others or (c) support the collecting of self-reports from the individual. 6.1.1 Measurement of Corporeal Reactions The attempt to ﬁnd ‘uninﬂuenced’ and ‘reliable’ indicators of emotions led researchers to focus on the physiological component of emotions and to analyse corporeal reactions. The heart rate, the activity of certain brain regions, activation of the abdominal viscera and/or skeletomuscular changes (facial expressive responses included) were considered suﬃcient indicators for an increase in the emotional experience of the test subject.
