A New Role for Chatbots: Automation of a Sleep-Dependent Memory Task.

Sleep is known to contribute to memory consolidation. Sleep-dependent memory is not often studied in patients with mild cognitive impairment (MCI), however, due to the need to attend sleep laboratories which are typically expensive, time-consuming and lacking in trained task administrators. We developed a conversation agent able to deliver a sleep-dependent memory task at home. Utility of the chatbot was confirmed through in-house testing and focus groups. The chatbot promises consistent task delivery and improved access for people with MCI.
