Research has identified three reading strategies that are affected in various ways by signaling--the emphasis of superordinate relationships in text. Using a structure strategy, readers follow the text's superordinate relations to focus on the text's message and how it relates to supportive details. Readers who use the detail/list strategy focus on learning facts; they develop a flat, list-like structure instead of developing hierarchical structures of interrelationships among major text propositions. In contrast to these two systematic strategies, the default/list strategy represents no systematic plan. The type of signaling studied in relation to these three strategies explicitly cued superordinate text structures. Such explicit signaling promoted a switch from the detail/list to the structure strategy; thus, it dramatically affected protocol organization and types of information recalled. Explicit signaling also facilitated the substitution of the structure strategy for the default/list strategy, increasing recall in those readers making the switch. It did not appear to influence readers who already were using the structure strategy. (RL)
