I am interested mainly in effects of social exclusion. My previous work concentrated on direct and displaced aggression as a result of being ostracized or rejected and factors that limit or boost those antisocial responses. Factors which captured my attentions were individual differences – mainly temperamental traits such as BIS/BAS system or Strelau’s Strength of Excitation and Inhibition, but also readiness for aggression, or gender of the excluder and gender of the excluded person. I also tested the effect of some situational conditions on intensity of aggressive response to exclusion – closeness of the relationship with excluder, comparative rejection, exclusion paradigm that was used or involvement of the aggression target in the exclusion incident. In my current project, I test the idea (that was the effect of previous studies), that the reaction to potential exclusion depends mainly on the understanding and interpretation of what happened. In my project “Social cues shaping emotional, physiological and behavioral responses to exclusion: engagement, feedback and relationship closeness” I propose that defining the ambiguous incident as exclusion is a complex process engaging social information processing. In other words, I try to answer the question, what situational or personal conditions must be met to consider the situation as ostracism or rejection. In my research, I also try to capture physiological correlates of emotional changes due to different cues inherited in exclusion manipulations. We measure micro-expression (EMG), heart rate and Inter-beat-intervals (ECG) and skin conductance level (SCL). We also use a new measure of physiological correlates of emotions – functional Infrared Thermal Imaging (fITI). It allows to capture the blood flow represented by temperature changes of some face areas (nose, oral area).
