the agent a clear pleasure and arousal signal, and thus, have to be the strongest signal that the agent receives.

The proposed different modulation for pleasure and arousal presented here are to be taken as one perspective on how to interpret the impact of the confidence. Different modulations can be designed and derived, but it will not be the focus of this paper. The use of the proposed modulation will not impact our final considerations.

Assessing my Opponent’s Mood
----------------------------

The same way an agent can assess its mood, it can also assess its opponents’ mood. This is important to give us a complete information about the agent’s perception of the entire competitive game, taking into consideration how it assesses its actions, and how it assess the others’ actions. To achieve the others’ assessment, we propose the use of an estimated confidence (E-Confidence), which is calculated using a partial estimation of the opponents’ hands.

To calculate its self-confidence, the agent uses the full game state, composed of the cards it has at hand and the board. When observing an opponent, the agent does not have access to the opponent’s hand, only to the cards on the board. The agent can,
