[Neuropsychology of event-based prospective memory]

Prospective memory is the capacity to remember actions that are to be performed in the future. Different studies from experimental neuropsychology attempt to unravel the neurocognitive processes underlying event-based prospective memory, that is, delayed actions that take place in a predetermined context, which would play the role of an external cue and would therefore contribute to successful intentional recall.

Taking the dynamism and flexibility of multiprocess theory as a reference, the main findings have highlighted the fact that prospective memory is influenced by, among other factors, the type of cue. Thus, when the cue is focal, the person tends to rely on spontaneous retrieval. In contrast, when the cue is not focal, there is usually a tendency towards monitoring. In parallel to this, studies in experimental neuropsychology have determined that the anterior prefrontal cortex and the dorsal frontoparietal network would participate in the cue monitoring processes. Conversely, the ventral frontoparietal network would intervene in automatic retrieval processes. Moreover, the role of the parietal lobe and the medial temporal lobe in prospective tasks is discussed.

This study defends the idea that both processing pathways (monitored and spontaneous) favour success in recalling the event-based intentional action. It must nevertheless be borne in mind that the moment a person decides to set one type of processing (or another) in motion it is influenced by the type of cue.
