Summary Conclusions

• SPel aims at
• create a process by which emotion processes
  influence learning processes (abduction) and
  vice-versa.
• explain the results from the agent's interaction
  with the world.
• transform the agent's interactions with the world
  in new knowledge, by
• creating chunks of actions that will be
  atomically executed
• creating chunks of eliciting rules that guide the
  agent interaction away from negative evaluated
  past interactions.

Future Work

• Bridge between emotions and abduction
