Question: Is [ Sense of agency : experiencing judging ]?
Answer: The conception of the sense of agency has greatly evolved over the years, mainly because of the various experimental methods employed. The consequences of this are the various theoretical interpretations given to the characteristics of the sense of agency. They can be explained in two main points: a non-unified definition of the sense of agency and an absence of experimental data testing alternative interpretations. First, protocols using attribution judgements have proven to be useful to gain better understanding of the attribution mechanism in schizophrenia. However, findings obtained with these judgments have often been used to conclude on deficits of the sense of agency in schizophrenia, whereas the sense of agency is only a sub component of these judgements.
