- 소개/요약The major aim of this project was to develop a laboratory-based task to facilitate measurement of a wide range of emotional experiences in alexithymia. Though overlapping, emotion constructs are distinct, and collecting multiple measurements in the same study offers importance nuances (Gruhn et al., 2013). In the paradigm, participants view video clips designed to elicit a particular emotional state, and asked a series of questions about their emotional experiences. From these questions measures of subjective emotional experience (i.e., labeling primary emotional experience, subjective arousal, subjective intensity), implicit measures of emotional experience (i.e., response time) and aspects of emotional complexity (i.e., granularity and dialecticism) will be collected. Many of these measures have been minimally studied in alexithymia, and hold promise for further elucidating the construct. A second goal of this project was to examine how interoceptive awareness interacts with emotional correlates of alexithymia and to investigate the effects of mindfulness meditation on improving deficits in alexithymia. Participants will be randomly assigned to receive either a brief mindfulness meditation or control recording. Before and after, they will complete measures of interoceptive accuracy. Mindfulness practices encourage individuals to attend to present-focused internal experiences, such as bodily sensations, thoughts, and emotions (Kabat-Zinn, 1990). As a therapeutic tool, mindfulness involves cultivating a nonjudgmental awareness of the present moment. Through the development of a novel laboratory-based design to assess behavioral correlates of alexithymia, the current study will facilitate measurement of a range of subjective, implicit, and complex emotional experiences, further delineating the nature of emotional processing deficits in alexithymia. Experiment two will examine how these measures relate to interoceptive accuracy, and whether they are responsive to a brief mindfulness meditation intervention. By collecting a range of emotional experiences, this paradigm will serve as a platform for future development of a laboratory-based assessment of alexithymia.
