Observational modeling effects for movement dynamics and movement outcome measures across differing task constraints: A meta-analysis
Ashford, Derek, Bennett, Simon J., & Davids, Keith W. (2006) Observational modeling effects for movement dynamics and movement outcome measures across differing task constraints: A meta-analysis. Journal of Motor Behavior, 38(3), pp. 185-205.
A meta-analysis was conducted on the observational modeling (OM) literature to quantify overall between-participant treatment effects obtained when acquiring movement behaviors. To evaluate predictions of the Visual Perception theoretical perspective on OM, effects were obtained and reported separately for movement dynamics (MD) and movement outcome (MO) measures. Overall mean OM treatment effect was = 0.77 for MD, and = 0.17 for MO measures. For both measures these effects reflected a significant advantage of OM over practice-only control conditions. Importantly, the magnitude of effects obtained was far stronger for MD compared to MO measures, confirming a distinctive response to OM during motor learning. The advantage for MD measures over OM measures was replicated for different types of task. OM was particularly beneficial for serial tasks ( = MD = 1.62 and MO = 0.61). There were slightly reduced effects for continuous tasks ( = MD = 1.01 and MO = 0.51), and smaller to medium sized effects for discrete tasks ( = MD = 0.56 and MO = 0.10). These findings are in line with tenets of the Visual Perception perspective for observational modeling, which suggests demonstrations primarily convey relative motions required to approximate modeled movement behaviors.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
