The survival processing effect describes the phenomenon that memory for items is better after they have been processed in the context of a fitness-related survival scenario as compared to alternative processing contexts. In the present study, we examined whether the survival processing memory advantage translates to memory for the order of processed items. Across two serial-recall experiments, we replicated the survival processing effect for free recall but did not find an additional survival processing advantage for serial recall when we controlled serial recall performance for the total number of words recalled per person. Adjusted serial recall performance was not better in the survival processing condition when compared to a moving and a relational pleasantness processing condition (Experiment 1), even when processing of the relational order of stimuli was explicitly endorsed in the survival processing task (Experiment 2). This finding is in line with the idea that enhanced item-specific rather than enhanced relational processing of items underlies the survival processing effect. Moreover, our findings indicate that survival processing does not increase memory efficiency for temporal context information.
