To test the hypothesis of a participation of inner speech in self-referential activity we reviewed 59 studies measuring brain activity during processing of self-information in the following self-domains: agency, self-recognition, emotions, personality traits, autobiographical memory, preference judgments, and REST. The left inferior frontal gyrus (LIFG) has been shown to sustain inner speech use. We calculated the percentage of studies reporting LIFG activity for each self-dimension. 55.9% of all studies reviewed identified LIFG (and presumably inner speech) activity during self-awareness tasks. Furthermore, (...) the LIFG was more frequently recruited during conceptual tasks (e.g., emotions, traits) than during perceptual tasks (e.g., agency, self-recognition). This supports the view of a relative involvement of inner speech in self-reflective processes. Crown Copyright © 2007 Published by Elsevier Inc. All rights reserved. (shrink)

A corrclational study is presented in which the existence of a relation between thc complexity (or richness) of thc seIfRi2;concept and a more or less frequent (...) use of seifRi2;taik is examined. The results are preliminary because scifRi2;taIk was measured with 21 pilotdnvcntory and the complexity of thc self-concept was scored using a new system.
