Social SignalsAn Overview1
Department of Psychology, Princeton University Princeton, New Jersey 08544
SYNOPSIS. Behavioral signals play an important role in the communication of members of a social group. This symposium explores those aspects of social signals that emphasize phylogenetic adaptations and endocrine coordination of communicatory behaviors. Species diversity in signalling modalities may be viewed as adaptations for effective communication in different habitats. Reproduction provides a rich context for social signalling, perhaps related to requirements for complex and intimate cooperation between partners. Hormones that regulate reproductive physiology also act to modulate the production and reception of social signals. The approaches of symposium contributors have benefited from the combination of field studies with the powerful analytic techniques of the laboratory. In addition, an appreciation of sources of information important for an animal in its natural habitat has focused the attention of physiological studies onto behaviorally meaningful problems.
