chapter_12_exercise_25: The data used in Chapter 12, Exercise 25

Description

Data from Chapter 12 Exercise 25 of Designing Experiments and Analyzing Data: A Model Comparison Perspective (4th edition; Maxwell, Delaney, & Kelley). The Kroes, Tendolkar, van Wingen, van Waarde, Strange, and Fernandez (2014) study of electroconvulsive therapy (ECT) and memory reconsolidation. Patients were shown two emotionally aversive slide-show stories; a week later one story was reactivated before three groups were formed (Group A: ECT, tested 24 hours later; Group B: ECT, tested immediately; Group C: no ECT). Each participant then received a multiple-choice memory test for both the reactivated and the non-reactivated story, giving a 3 (group) by 2 (reactivation) design with group between subjects and reactivation within subjects. Scores are percentage correct. The same study also provides the one-way data of chapter_4_exercise_21; the reactivated scores here are those Chapter 4 memory scores.
