The paper presents an open usable tool, the ACME shop paradigm, for experimentally studying self-objectification due to objectifying work activities. The paradigm consists of a simulation in which participants are asked to perform an objectifying (repetitive, fragmented, and other directed) a non-objectifying work activity. Two studies tested the construct (convergent and discriminant) validity of the paradigm by showing its effectiveness in inducing different facets of working self-objectification - but not other forms of dehumanization - in laboratory and online settings. In the objectifying condition, participants self-objectified more, that is they self-attributed less human mental state and self-perceived as more instrument-like than participants in the non-objectifying and control (an activity characterized by objectifying features but not related to the work domain) conditions. Moreover, the convergent and discriminant validity of the paradigm in inducing self-objectification, and no other type of dehumanization, was demonstrated by the significant impact of objectifying condition on self-attribution of both agency and experience and not on self-perception as animal-like. Applications of the paradigm will be discussed.
