摘要

Design: Multiple-probe design across participants with a pre-, within-, and post-treatment multiple-generalization probes. Allocation: All participants completed the same experimental conditions. Therefore, no differences existed in allocation to treatment or condition. The researchers provided no information regarding procedures for participant order assignment. Blinding: The primary investigator conducted all phases and was therefore not blinded to the study purpose.
