Abstract
The emerging field of social signal processing can benefit from a theoretical framework to guide future research activities. The present article aims at drawing attention to two areas of research that devoted considerable efforts to the understanding of social behaviour: ethology and social psychology. With a long tradition in the study of animal signals, ethology and evolutionary biology have developed theoretical concepts to account for the functional significance of signalling. For example, the consideration of divergent selective pressures responsible for the evolution of signalling and social cognition emphasized the importance of two classes of indicators: informative cues and communicative signals. Social psychology, on the other hand, investigates emotional expression and interpersonal relationships, with a focus on the mechanisms underlying the production and interpretation of social signals and cues. Based on the theoretical considerations developed in these two fields, we propose a model that integrates the processing of perceivable individual features (social signals and cues) with contextual information, and we suggest that output of computer-based processing systems should be derived in terms of functional significance rather than in terms of absolute conceptual meaning.

Notes
Though not extensively, this paper will also consider notions of linguistics and pragmatics.
We will discuss the issue of encoding in a later section of this paper.
Although the development of the capacity to speak can be relatively costly, once that capacity is acquired, there is little variability in cost for the production of different types of words/signals.
Although similar, our concept of meta-communicative component is not precisely the same as the concept of meta-communicative signal introduced by Bekoff (1972).
