184 Socially Intelligent Agents

performing task level actions, the agents engage in speech acts and generate
gestures, facial expressions, and affective speech modulation based on proper-
ties of their social state.
The following are annotated traces of the system where the only difference
is a change in the “personality” of the one agent. In the first trace, Steve
treats Jack rudely, in the second, he treats him fairly. Text generation is ex-
tremely simplistic: agents actually communicate through a more stylised plan-
communication language.
Rude Interaction:
Jack: I want to make-some-big-money. [Creates a new plan containing this goal – enter car,
drive to market, exit car, buy lotto ticket. Looks concerned, scratches his head, then, after de-
vising a plan looks hopeful.]
Steve: I want to catch-some-waves. [Creates a new plan containing this goal. Looks concerned,
scratches head. Surfing is important to Steve but a plan cannot be generated due to an unestab-
lished “wave-location” precondition.]
Jack: [“sees” Steve’s distress and requests information.] Hey Steve, what’s wrong?
Steve: [Locates the feature in memory generating the most intense negative emotional excitation
(see [1]). Communicates the associated plan in a distressed tone of voice.] I want to catch some
waves but can’t find any good breakers.
Jack: [Incorporates Steve’s plan into memory and locates relevant information. Jack was previ-
ously told of a “plan” that establishes Steve’s blocked subgoal] Steve, does it help that someone
did say there’s some great waves near the pier?
Steve: [Incorporates Jack’s information. Derives a plan to go surfing. Looks hopeful.]
Jack: [Perceives Steve’s change in expression and seeks to confirm his expectation that the in-
formation he provided helped Steve.] So that information helped?
Steve: [Handles Jack’s information request.] Yes Jack. I plan to drive the car to the beach, then
I plan to surf-my-brains-out.
Jack: [Incorporates Steve’s revised plan and finds a conflict with his own plans. Based on per-
sonality, Jack attempts to negotiate a fair solution.] Wait a second. Our plans conflict. I plan to
drive the car to the quicky-mart then I plan to buy a-lottery-ticket.
Steve: [Incorporates Jack’s plan and recognizes the same interaction. Based on personality
model, Steve responds to interaction differently. He devises a plan that satisfies his own goals
without regard to any conflicts it may introduce in Jack’s plans. Steve exits stage right.] Later
dude, I’m driving the car to the beach.
Jack: [Perceives that car has departed without him. Looks angry. Says in angry voice:] Iwant
to kill-my-roommate.
Cooperative Interaction: Jack: [Incorporates Steve’s revised plan and finds a conflict
with his own plans. Based on personality, Jack attempts to negotiate a fair solution.] Wait a
second. Our plans conflict. I plan to drive the car to the-quicky-mart then I plan to buy a-lottery-
ticket.
Steve: [Incorporates Jack’s plan and recognizes the same interaction. Based on Steve having
somewhat lower social status, he takes the initiative in repairing the conflict.] Well, I could
