Acting with machines: a systematic review and meta-analysis of the sense of agency in human-artificial agent interaction (retrospective registration)

RETROSPECTIVE REGISTRATION. This registration is submitted after completion of the review. The protocol was prepared on 18 October 2026, after title/abstract screening and before full-text screening, data extraction and analysis, but was not registered at that time. The registration reproduces that protocol; deviations from it are disclosed in the attached document and in the corresponding fields. Systematic review and meta-analysis of experimental studies comparing the sense of agency (implicit: intentional/temporal binding; explicit: judgments of agency, control and authorship) when adults act or decide together with an artificial agent (robot, autonomous virtual agent, computer partner, AI advisor, chatbot/LLM) versus acting alone or with a human partner. Authors: Martina Nicole Modesti, Antonio Del Casale, Stefano Ferracuti (Sapienza University of Rome).
