Hi Boris, Thanks for the references. Do you have a diagram to go along with your explanation? That would be much appreciated. A diagram helps the explanatory cloud to be decomposed into discrete components. I'm looking at attention rather than motivation. Motivation is handled in PAM-P2 through the use of homeostatic variables and "urges", deltas between current and target homeostatic variable values. For me, attention is the filtering or re-prioritization of goals. In the PAM-P2 system I have an intuition that a higher level of selection occurs than is explained than by basic action selection. In PAM-P2 there are two action selectors: the Reactor, which matches existing solutions to sensory stimuli, and the Deliberator which matches existing solutions with active situations and needs (goals). Both action selectors operate in a case based manner, where "solutions"are the cases. Once a solution is selected, it may generate subgoals to assist in attaining theoverall solution. My intuition tells me that there should be another, higher level of goal selection. (Or, perhaps goalfiltering, not exactly sure). Something that operates above action selection that takes into account all the possible goals the system could have and ensures that the most important at the current moment are part of the agenda. Your thoughts? ~PM From: [email protected] To: [email protected] Subject: Re: [agi] Goal Selection Date: Tue, 14 May 2013 17:15:51 -0400
You're really trying to understand how human motivation works. I already posted this, but in case you missed: Human motivation: developmental perspective. Motivation is all mental mechanisms that drive our behavior, in which I include cognitive behavior: analysis, introspection, & planning for somatic behavior. Values / motives in humans & higher animals can be divided into three broad categories, according to the mechanism that formed or selected them: Evolution selects instincts fit for their own propagation, innate but subsequently modulated by usage, Conditioning value-charges stimuli coincident with previously value-loaded stimuli in time or space, Cognitive curiosity searches / selects for predictive patterns, even if they consist of value-free stimuli. Higher mechanisms accelerate adaptive value acquisition by acting on increasingly mediated responses: from immediate behavioral reactions to longer-term attention, prediction, & planning. Brain areas that implement these value-acquisition mechanisms likely evolved in the same sequence: Instincts, largely physiological & traceable to 4Fs, are encoded mainly in brainstem & hypothalamus. Conditioning is initiated by basal ganglia & limbic system, then extended & generalized by neocortex. Predictive curiosity is an innate driver of neocortex, which is also heavily modulated by lower motives. This scheme is vaguely similar to triune brain model, but in my interpretation these substrates differ mainly in the mechanism by which they acquire values, rather than in resulting & relatively transient motives themselves. These value acquisition mechanisms are innate, but their relative strength varies. Our instincts are pretty basic & similar to those of other mammals. An excellent account of that level of motivation is Jaak Panksepp‘s “Archaeology of Mind: Neuroevolutionary Origins of Human Emotions“. The discussion below is mostly on conditioning & cognition: increasingly adaptive mechanisms which seem to strengthen with our personal growth: http://cognitive-focus.blogspot.com/2012/06/motivation-evolution-of-value.html From: Piaget Modeler Sent: Tuesday, May 14, 2013 4:17 PM To: AGI Subject: RE: [agi] Goal Selection Getting Closer: Top-down versus bottom up attentional control: a failed theoretical dichotomy http://ems.psy.vu.nl/userpages/theeuwes/Trends_2012_Awh.pdf The priority map notion is closer to what I was looking for. I know that priorities fit in somehow. ~PM AGI | Archives | Modify Your Subscription AGI | Archives | Modify Your Subscription ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
