Figure 1.
Mean dendrograms indicating mental representation structure of action observation training group at (A) pre-test, (B) post-test and (C) retention test. The horizontal line indicates the critical Euclidean distance. The critical value of the Euclidean distance (dcrit) was 3.41 for an α level of 5%. The basic action concepts (BACs) above this line are considered not related. The underlined BACs below this line are considered functionally related to each other.
