Action representation across ages and cultures: Recognition of action means-end change in German and Chinese children and adults

Actions can be represented as a hierarchy of goals and means, whereas the granularity of the top level depends on the action's complexity. So far, most evidence comes from imitation studies. We explored this issue by evaluating the detection of means and end changes in a recognition paradigm across ages and cultures. German and Chinese preschoolers (n = 53) and adults (n = 58) studied videos of tool-use actions differing in complexity and familiarity. In the test phase, participants judged identical, means-changed and end-changed actions as same or different. Changes of the actions' end were generally identified more accurately independent of age and culture. Means' changes, but not ends' changes, were detected more frequently for complex than for simple actions. Changes in familiar actions were recognised better than changes in unfamiliar actions. The data supports a hierarchical model of action representation where the end information is superordinate to means information
