Work and freedom? Working self-objectification and belief in personal free will

The current work aimed to extend the burgeoning literature on working objectification by investigating the effects of particular job activities on self-perception. By integrating relevant theoretical reflections with recent empirical evidence, we expected that performing objectifying (i.e., repetitive, fragmented, and other-directed) tasks would affect participants' self-objectification and, in turn, their belief in personal free will. In three studies, we consistently found that performing a manual (Study 1 and Study 2) or a computer (Study 3) objectifying task (vs. a non-objectifying task and vs. the baseline condition) led participants to objectify themselves in terms of both decreased self-attribution of human mental states (Study 1 and Study 3) and increased self-perception of being instrument-like (Study 2 and Study 3). Crucially, this increased self-objectification mediated the relationship between performing an objectifying activity and the participants' decreased belief in personal free will. The theoretical and practical implications of these findings are considered.
