Dr. Daniel S. Levine is talking about how the brain works. His work is in human psychology, and he hopes that some of this knowledge can be useful for knowledge based systems.

Our memory can play tricks on us by creating information that was not there in the first place because other information “suggests” it.

Children or novices store and remember things literally. Adults or experts store and remember as “gists”. The passage from verbatim to gists will happen with the familiarity of the subject and with the development of cognitive capacities such as analogy.

The gists will create some challenges because sometimes the wrong gist is remembered (or encoded). Gists are required to understand trends and to see analogies. Verbatim is needed to override inaccuracies.

We can override our learned gist rules and we can follow those rules. We can be automatic or controlled; deliberate or heuristic; gist or verbatim. People will shift their level of representation (task calibration) based on some different factors.

How can rule systems adapt their level of representation based on the goal? We have not solved that problem yet. How do you decide which level or representation that you need to resolve that problem?

He ends his talk on that note, indicating that they are working on understanding task calibration better so that one day it can maybe applied to knowledge systems.
