Data and analysis code for: Observed reversals of a computer mouse postdictively bias ambiguous motion judgements even without a visible hand

Single-trial data and analysis code for the article "Observed reversals of a computer mouse postdictively bias ambiguous motion judgements even without a visible hand" (Nomura & Ogawa). The dataset osf_main_long.csv contains one row per trial (3,960 rows: 28 main-sample participants and 5 pilot participants, 120 trials each). Columns: subject_id (1-5 pilot cohort, 6-33 main sample), cohort ("pilot" / "main"; confirmatory analyses use "main" only), source ("Hand" / "Mouse-only"), condition ("Control" / "Non-invert" / "Pre" / "At" / "Post"), response_bounce (1 = "bounce", 0 = "stream"), block_half ("first" / "second" for the main sample; NA for pilot rows). bpogv1_confirmatory_osf.R reproduces the confirmatory, robustness and exploratory analyses reported in the article (R 4.5.1, lme4, geepack). pilot_plan.R reproduces the sample-size planning from the pilot cohort.
