Abbott2 is an extension of work by Dolores
Cañamero (incorporating ideas from the Cognition
and Affect Project at Buirmingham University). Abbotts are constructed
within a subsumption style framework, where more complex behaviours are
implemented by adding agents to the society without modifying existing
society members. Abbotts are endowed with primitive motivational states
- impulses to action based on bodily needs - and “emotions” - peripheral
and cognitive responses triggered by the recognition of a significant event.
“Emotions” perform an alarm/meta-management function in Abbott, releasing
chemicals (hormones, neuromodulators, and neurotransmitters) to alter both
the perception of external stimuli and the activation levels of Abbott.s
internal motivational drives. The code for Abbott2
is given below.
We have also performed a number of simple experiments using our Abbott3 design and the Gridland toolkit. These experiments are described in chapter 8 of Allen . The raw results, and instructions for reproducing these results, can be found here.
