Does action make you faster? A retrieval‐based approach to investigating the origins of the enactment effect

Abstract

The enactment effect, the stable finding that memory for action phrases is enhanced in a subject-performed compared to a verbal task (SPT; VT), has repeatedly been demonstrated. The question remains whether the enactment effect has to do with specific characteristics of the SPT-retrieval process. Experiment 1 tested younger and older adults in a within-subjects design with two direct free recall tests. Thorough analyses of the recall process showed that the benefit from self-performing the items becomes apparent early into the retrieval phase for both age groups. Experiment 2 tested the same age groups with a retention phase of 30 minutes. The same general results pattern emerged. The acceleration of the recall process in SPTs is indicative of a heightened accessibility of the actively encoded material, making it less susceptible to forgetting. This property of SPTs must be taken into account when trying to determine the origins of the enactment effect.

Exploring Spared Capacity in Persons With Dementia: What WiiTMCan Learn

“…Enactment of an item, performing a physical movement related or unrelated to the item to be remembered (e.g., rocking the arms back and forth while saying "baby"), has been found to enhance memory for that item compared to just reading a word list of items to be remembered (Engelkamp, 1998). Spranger, Schatz, and Knopf (2008) found an acceleration of recall in participants in the enactment group, suggesting that one of the benefits of enactment is a heightened accessibility of information when there is motor encoding. The question of whether enhanced recall results from merely physical arousal or context-specific movement was addressed by von Essen and Nilsson (2003).…”

Reducing Sexual Victimization Among Adolescent Girls: A Randomized Controlled Pilot Trial of My Voice, My Choice

“…Based on research that supports the benefits of behavioral practice for learning social skills (Mueser & Bellack, 2007;Spranger, Schatz, & Knopf, 2008), MVMC provides participants opportunities to practice assertive resistance and to receive feedback on their use of these skills. This practice is conducted in an immersive virtual environment (IVE), using simulations of situations that pose potential risk for sexual victimization.…”

Is there a memory profit after repeated learning of subject-performed actions? Comparing direct and long-term memory performance level as a function of age

“…Since a between‐subject design was chosen, the participants underwent the same mode of encoding at each session. This procedure was chosen in order to avoid transfer effects which are found in present research of our group using a within‐person‐design and are sometimes reported for similar studies of other research groups (see, e.g., Jahn & Engelkamp, 2003; Spranger, Schatz & Knopf, 2008).…”
