Acquisition-test interactions between

The effects of changes in context on recognition memory were investigated in two experiments. In Experiment 1 target items were embedded in congruous or incongruous sentence frames and then tested in the original, new congruous, or new incongruous contexts. Experiment 2 included a third encoding condition; targets were also embedded in abstract definitional sentences. Both experiments revealed a reliable crossover interaction between the initial encoding condition and the mode of the changed context. Congruous items were recognized better in new congruous contexts, whereas incongruous items were recognized better in new incongruous contexts. Recognition of definitional items was equally impaired by both context changes. The results suggest the importance of the symmetry between acquisition and test encoding dimensions. These experiments also point out the need to distinguish between different ways in which the concept “integration” is used in current research.
