"The main aim of the present study is to investigate the relationship between knowledge represented by language and ability in purposefully remembering information about new environments. Subjects were 22 6year-old children and 22 adults, whose verbal descriptions of a route in a novel urban environment were analyzed. Results show that adults remember more structural features of urban environments than low landmark potential elements. The same trend was observed in 6-year-olds with high conceptual-linguistic ability, while the opposite trend was found in 6year-olds with normal such ability. The results are interpreted focusing on the role of the "knowledge base"in memory strategies."
