We evaluated the time course of persistent automatic spreading activation from a mediated list of indirect associates (e.g., meow, day, and basement) that all converged upon a non-presented critical item (CI; e.g., black). Mediated lists were related to CIs through non-presented mediators (e.g., cat, night, and bottom). Three speeded tasks were used to evaluate the time course of semantic activation of the CI: a continuous semantic classification task (concrete/abstract decisions), a naming task (reading words aloud), or a recognition test (old/new memory decisions). Test lists were presented immediately following the mediated lists, and CIs were presented in the first, third, or eighth positions. The results revealed that in both the classification and naming tasks, CI priming was greatest in the first test position and declined across the remaining test positions. Importantly, priming was statistically reliable in the late test positions, providing evidence for long-term semantic priming (i.e., across positions on immediate tasks). False recognition, however, was stable across test positions. Collectively, these patterns suggest that spreading-activation processes decline, consistent with implicit spreading activation, and these processes may contribute to long-term false recognition.
Is Pupil Activity Associated With the Strength of Memory Signal for Words in a Continuous Recognition Memory Paradigm?
