Background

The ability to recognize others’ emotions is crucial for the development and maintenance of social relations. Emotion recognition (ER) is an ability developed in childhood through interacting with significant others. Growing up in abusive or neglecting environments can impact emotional learning and thus impair the ability to correctly identify other’s emotions. Individuals with a history of child maltreatment seem to have difficulties interpreting other people’s emotional facial expressions. They also frequently misinterpret neutral facial expressions as negative and show abnormal Amygdala responses to these expressions.

Studies on emotional processing and ER to date, however, mainly used experimental paradigms, e.g. ER stimuli, that comprise pictures or videos of Caucasian faces. Also, they focus on individuals living in the U.S. or Europe. However, the way we process and respond to emotional signals depends on our cultural background and it thus seems important to assess whether previous findings generalize to individuals with various cultural backgrounds.

Existing collaborations

Monique Pfaltz (University of Zurich, Switzerland) and Misari Oe (Kurume University, Japan) currently examine whether in adult Japanese individuals, child maltreatment is related to impaired recognition of emotional and neutral facial expressions. They also assess whether child maltreatment affects the intensity of self-reported and physiological (electrodermal, facial EMG, electrocardiogram) responses to video clips inducing negative and positive emotional states in Swiss and Japanese individuals.

Aims

  1. To build up a broader network of researchers from various countries who will conduct experimental studies to broaden our understanding of trauma-induced, potentially culture-dependent alterations in emotional processing, which may affect the quality of interpersonal relationships and thus mental and physical well-being.

  2. These researchers will assess emotional reactivity, emotion recognition from different modalities, and potentially other emotional processes, in traumatized individuals across continents and cultures, with the long-term goal to develop interventions aimed at improving affected individuals’ interpersonal relationships.

  3. First steps will be to define common and country/culture-specific research questions, to get an overview of existing experimental paradigms and, where necessary, to adapt these paradigms in collaboration with basic emotion researchers, thereby building a bridge between basic and clinical research.

Methods

Children and adults with a history of child maltreatment shall be assessed, using experimental (emotion recognition, emotion induction and other) paradigms as well as psychophysiological approaches (e.g. facial EMG, electrocardiogram, electrodermal activity, recording of attentional patterns and eye movements by means of eye tracking).
