Isi artikelEvent sequences or scripts are the conceptual representations of activities in memory. Traditional views hold that events are represented in modal networks and are retrieved by associative strategies. The embodied cognition approach holds that knowledge is grounded in perception and retrieved by mental simulation. We used a script generation task where event sequences of activities had to be produced. Activities varied in their degree of familiarity. In a regressional design we investigated whether a modal or perceptual variables best predicted knowledge retrieval to gain insight into the underlying representation. Retrieval depended on the familiarity of the activity. While novel activities mainly relied on perception-based simulation and to a lesser extent on associative strategies, moderately familiar activities showed the opposite pattern, and events of familiar activities were retrieved by association alone. We conclude that a modal structures exist in all representations that become stronger with increasing frequency and finally prevail over perceptual structures.
