Our results show that the perception of displays related to affect greatly influences both the types of display produced and also the survival prospects of agents. Relative to agents that do not perceive rival agent internal state, affect perceivers prosper if the initial environment in which they reside provides numerous opportunities for interaction with other agents and resources. Conversely, where the initial environment with sparse resources does not allow for regular interaction, ability to perceive affect is not as facilitatory to survival. Furthermore, the agents evolve particular display strategies distorting the expression of affect and greatly influencing the proportion of affect perceiving to nonaffect perceiving agents over evolutionary time.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Avila-García, Orlando</style></author><author><style face="normal" font="default" size="100%">Lola Cañamero</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Stefan Schaal</style></author><author><style face="normal" font="default" size="100%">Auke Jan Ijspeert</style></author><author><style face="normal" font="default" size="100%">Aude Billard</style></author><author><style face="normal" font="default" size="100%">Sethu Vijayakumar</style></author><author><style face="normal" font="default" size="100%">John Hallam</style></author><author><style face="normal" font="default" size="100%">Jean-Arcady Meyer</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Using Hormonal Feedback to Modulate Action Selection in a Competitive Scenario</style></title><secondary-title><style face="normal" font="default" size="100%">From Animals to Animats 8: Proc. 8th Intl.

We have framed our study in the context of a dynamic, multirobot, competitive &quot;two-resource&quot; action selection problem. The introduction of competitors has important consequences for action selection. We first show how the interaction between robots introduces new forms of environmental complexity that affect their viability. Secondly, we propose a &quot;hormone-like&quot; mechanism that, modulating the input of the ASM, tackles these new sources of complexity.</style></abstract></record></records></xml>
