AbstractWithin the context of an interactive anagram-solving task, the present studies tested predictions about the role of cognitive anticipation in both source and item memory. After working in pairs to solve anagram problems, participants were surprised by a source-monitoring test focused on the source of solutions (self vs. partner, Experiment 1) or a standard recognition test focused on the solutions themselves (Experiment 2). With the intention of affecting the opportunity to anticipate partners' solutions, two variables were manipulated: anagram difficulty (easy vs. hard) and the delaybetween the presentation of an anagram problem and theprompt tha t designated one member of each pair as the anagram solver. Consistent w i th predictions, asthe opportunity t oanticipate partners'solutions increased, there was a decrease in source accuracy suggesting increased confusion about whether the solution had been self- or partner-generated. Generation-effect failures were observed in item memory. However, these failures reflected increases in item memory for partners' responses rather than decreases in memory for self-generated ones. These studies suggest that when opportunities to anticipate partners' responses are available, self-generative activities may be associated with both self-and partner-generated items, influencing the expression of the generation effect.
