Comparable monotonic rates of forgetting of one-trial place memory in the watermaze and the event arena DMP tasks. Normalization of the watermaze data to chance was calculated as the percentage of time swimming in the correct zone divided by the chance level (12.5%, eight zones). Normalization of the event arena data was calculated as the percentage of time digging in the correct sandwell divided by the chance level (20%, five sandwells; based on data of Bast et al. [2005]). Stippled horizontal line indicates chance value of normalized performance measures. Means ± 1 SEM.
