Forgetting to perform an intended action at the appropriate future moment – i.e., prospective memory (PM) – is reported as the most frequent memory failure in our everyday life. In order to relieve the burden of intention maintenance in internal memory and increase the likelihood of remembering to carry out these delayed intentions, we can rely on the external environment. For instance, this may involve setting a reminder such as an alarm or calendar alert or keeping a to-do-list. The use of physical actions to create external triggers for delayed intentions is referred to as intention offloading. Despite the relevance of intention offloading behavior for everyday functioning, little research has been conducted to understand this process and its development across the lifespan. The goal of this study is to determine under which conditions reminders benefit prospective memory. A sample of younger and older adults will be asked to perform a prospective memory task and we will manipulate if and which PM component they can offload. The results will shed light on the most effective strategies to support the fulfilment of delayed intentions in younger and older adults.
