Methods and systems for enhancing and/or improving one's memory are disclosed. In one embodiment of the invention, a computer-implemented memory assistance system is comprised of a client and a memory assistance server. The memory assistance server includes a signal processing server to receive and process media signals (e.g., audio, video, or photographs) and associated data received from the client. The signal processing server includes a variety of servers or services for processing signals and/or data. Each signal processing server or service identifies characteristics of the received media signal that are relevant to aiding a user in recalling and/or reinforcing an existing memory of a particular event or fact. In addition, the memory assistance server includes presentation logic to generate one or more media clips from the received media signal. Furthermore, the presentation logic determines a time and medium to present one or more media clips to a user so as to aid the user in recalling and/or reinforcing one or more existing memories of a particular event or fact.
