METHODS FOR MEASURING MOVEMENT REPRESENTATIONS I. Introduction  Objective: Understanding the methods representations in cognitive psychology. used for analyzing movement  Key Concepts: Structural Dimensional Analysis-Motoric (SDA-M), hierarchical cluster analysis, dendrograms. II. Structural Dimensional Analysis-Motoric (SDA-M) 1. Overview  Definition: A method for analyzing action representations within long-term memory.  Developed by: Thomas Schack (2010, 2012).  Objective: To examine the formation and structure of clusters of Basic Action Concepts (BACs) within action representations. 2. Procedure  Sorting Process: Participants are presented with a BAC (e.g., "upright body") in the anchor position and must decide if it is associated with another BAC (e.g., "swing arms back") displayed in the reference position.  Decision Making: Participants decide whether a BAC should be "assigned" or "put away" from the anchor position, indicating their functional relationship.  Iterative Process: The process is repeated for each BAC with comparisons against all other BACs.  Completion: The sorting process concludes once every BAC has been placed in the anchor position and compared to all other BACs. 3. Analysis  Cluster Formation: SDA-M identifies which BACs are assigned to the same cluster due to their functional interdependence (functional phases).  Visualization: Cluster solutions are visualized using dendrograms, allowing for easy interpretation and comparison of participant representations. III. Applications  Comparative Studies: SDA-M can be used to compare participants of different skill levels (e.g., novices vs. experts).  Repeated Measurements: It is useful for evaluating changes in the representation structure over time (e.g., effects of intervention or training). IV. Key Takeaways  Structural Dimensional Analysis-Motoric (SDA-M) is a method for analyzing action representations.  Participants make decisions about the functional relationships between Basic Action Concepts (BACs).  The method identifies clusters of BACs within action representations.  Dendrograms visualize cluster solutions, aiding in interpretation and comparison.  SDA-M is applicable to comparative studies and repeated measurements of representation structures.
