Abstract

The distinction between the Self and others is in the heart of social cognition. Existing evidence links these processes with the so-called default mode network (DMN). Here, using EEG data, DMN connectivity in the alpha frequency band was investigated during thinking about own qualities and qualities of other people and during dynamic evaluation of these qualities by means of presented adjectives. In the former case, DMN connectivity between the DMN and the lateral prefrontal cortex was most increased during thinking about own qualities, as compared to qualities of others. In the latter case, on the contrary, self-evaluation was accompanied by the smallest level of DMN connectivity, whereas the highest level was observed during evaluation of a stranger. This results show that connectivity between the DMN and the lateral prefrontal cortex in the alpha frequency band is involved in both cases, but the degree of its involvements depends on the complexity of the task, which is maximal for the dynamic evaluation of a stranger and for the contemplating own qualities.
