Weekly QUEST Discussion Topics and News, 1 Nov

October 31, 2013 Leave a comment

The first topic is to allow discussion for those preparing ERFs – to provide the elevator speeches for people to provide feedback on emphasis etc. –

The second topic is a review on our list of tenets (summary doc on tenets) – from the perspective of the implementation considerations each impose (possibly in the light of an implementation like the LaRue work)

Capt Amerika is out of town this week on travel. Dr. Terry Wilson would like to use this week’s QUEST discussion to story board how to modify the broker/client/provider demo to start down the path of a layered sensing ‘Questified’ system.

For anyone available, the meeting will be in the CCR conference room and the end time is extended to 1400 for this week only (if you are able to stay).

The topic from the last two weeks is the set of research articles starting from ‘Hypothetical-thinking based on cognitive decoupling and thinking dispositions in a dual cognitive agent’, by Larue et al, Biologically inspired cognitive architectures (2013) 6, 67-75, will be our main topic – several of our QUEST colleagues expressed an interest in understanding the work so they could reproduce the approach but using our applications. Dr. Terry Wilson has investigated some of the tools so we will spend this week having a more detailed discussion than usual emphasizing the implementation of many of our quest ideas using these tools – but having the conversation using the tapestry of the Larue work to bring meat to the discussion. The lead article presents an implementation of the hypothetical-thinking capacities, based on Stanovich’s tripartite framework (Stanovich, 2009). They simulated the Wason card selection task with four different cognitive styles (strongly reactive, purely executive, weakly reflective, purely reflective) and were able to reproduce the results and types of errors found in studies of human reasoning abilities. The first three profiles account for the results of 90% of human subjects (all those who provide answers that are not acceptable by logical standards). The strongly reactive profile gave a plausible account of the way humans provide the logically incorrect answer to the task. We want to have a discussion that addresses the application of the model/approach to problems we care about (this will be one main point of discussion – options for the choice of a driver problem / set of problems to flush out the approach) AND more importantly on using the approach to implement our tenets. Cathy has obtained many of the references from the article and posted them on the VDL.

The strongly reactive profile gave a plausible account of the way humans provide the logically incorrect answer to the task. The purely executive and weakly reflective gave an account of how subjects can provide part of the correct answer. The last profile (purely reflective), a much a much slower process, produces a complete and correct answer by logical standards. While the purely reflective process was the only one able to do this, it is to be noted that the purely executive system was able to provide a correct (but incomplete) answer using less computational resources (time).

Weekly QUEST Discussion Topics and News
4th October, 2013

I spent the week considering working memory and the models of Baddeley / Hitch and the information from the Cowan article on his model/insights. I’m not sure if there is anything additional I gained out of the reviews that we haven’t discussed but I suspect we will start with those discussions.

I then went back to consider the challenge of bringing some structure to the concept of ‘meaning’. We’ve had this discussion recently but I wanted to reconsider it in terms of our recent views of type 1 and type 2 and the implications to ‘meaning’. This reminded me of a driver problem we recommended some time ago that makes a great testbed application for engineering solutions consistent with our ‘Theory of Consciousness’. The driver problem was to capture our weekly news stories in a representation that could be aligned to by each of us.

Another topic that has consumed some bandwidth is the effort under PCPADx spiral 1 on defining events. This has direct correlation to our recent discussions on situations/chunks/qualia = events. So I want to expose the group to that discussion so we can brainstorm and provide feedback to the pcpadx team.

The most exciting topic for the week is a research article ‘Hypothetical-thinking based on cognitive decoupling and thinking dispositions in a dual cognitive agent’, by Larue et al, Biologically inspired cognitive architectures (2013) 6, 67-75. They present an implementation of the hypothetical-thinking capacities, based on Stanovich’s tripartite framework (Stanovich, 2009).
