Roger Ratcliff, Michael J. Hacker

Perception & Psychophysics, 1981. DOI 10.3758/bf03214286

Has this study been replicated?

The atlas records 1 replication of this study. Recorded outcomes: 1 failed. The earliest on record is from 2025.

Replications

• A replication of Ratcliff and Hacker's (1981) Same-Different task variant (Experiment 1), Losier Poirier et al. (2025). The Quantitative Methods for Psychology. Outcome recorded: failed. We observe that manipulating task instructions does not generate any significant difference between conditions and that there is no speed-accuracy trade-off, opposing Ratcliff and Hacker's (1981) original results. Outcome read from the abstract. View paper
