Congruity Effects Between Materials and Processing Tasks in the Survival Processing Paradigm

摘要

Nairne, Thompson, and Pandeirada (2007) reported a series of experiments in which processing unrelated words in terns of their relevance to a grasslands survival scenario led to better retention relative to other semantic processing tasks. The impetus for their study was the premise that human memory systems evolved under the selection pressures of our ancestral past. In 3 experiments, we extended this functional approach to investigate the congruity effect-the common finding that people remember items better if those items are congruent with the way in which they are processed. Experiment l was a replication of Nairne et al.'s (2007) experiment and showed congruity effects in the survival processing paradigm. To avoid potential item-selection artifacts from randomly selected words, we manipulated congruence between words and processing condition in Experiments 2 and 3. As expected, final recall was highest when the type of processing and the materials were congruent, indicating that people remember stimuli better if the stimuli are congruent with the goals associated with their processing. However, contrary to our predictions, no survival processing advantage emerged between the 2 congruent conditions or for a list of irrelevant words. When congruity was controlled in a mixed list design, the survival processing advantage disappeared.
