Cheating as a mixed strategy in a simple model of aggressive communication
Article Abstract:
It has been possible to confirm that a mixture of honest and deceptive signals can be evolutionarily stable in a symmetric conflict situation. This research involved using a simple model of aggressive communication to establish whether cheating can be an element of a mixed evolutionarily stable strategy. It is suggested that, if the proportion of weak individuals is fixed, theoretically and in contrast to the assumption that cheating must be unusual in an evolutionarily stable signalling system, many weak individuals can cheat in an evolutionarily stable system.

Assessment of expected performance and Zahavi's notion of signal
Article Abstract:
A comment on the proposed theory of a classification of signals and nonsignals and that ritualized signals display motivation is presented. By definition, certain characteristics can be called signals such asbody size and territorial holding ability which are classified as nonsignals inthe theory. Also, ritualized behavior may be the combination of features in theanimal and may not necessarily express motivation.

Some clarifications of the notion of signals: a reply to Richner
Article Abstract:
A reply to an article by Henz Richner (1993) is presented. Clarifications on the definition of signals and the evolution of signals such as body size and territorial behavior are also presented. In the discussion of ritualization, a clarification is made on the purpose of the usage of the topic. It was to serveas a focal point on the evolution of signals and not on ritualized behavior perse.
