Focusing on sexually selected signals, it is argued that dynamic variation in selection pressures can often explain why multiple signals coexist.Abstract:
The ubiquity of multiple signalling is a long-standing puzzle in the study of animal communication: given the costs of producing and receiving signals, why use more than a single cue? Focusing on sexually selected signals, I argue that dynamic variation in selection pressures can often explain why multiple signals coexist. In contrast to earlier research, which has taken a largely static view of the world, new insights highlight how fluctuations in ecological and social environments, as well as non-equilibrium dynamics intrinsic to coevolutionary systems, can maintain both multiple redundant and non-redundant signals. Future challenges will include identifying the circumstances under which environmental fluctuations lead to multiple signalling, and the consequences of such fluctuations for speciation in multiple-signalling species.read more

TL;DR: In this paper, the authors review behavioural and neuroimaging studies of face-voice integration in the context of person perception and find evidence for interference between facial and vocal information during affect recognition or identity processing.

An introduction to multimodal communication

TL;DR: The history of the study of complexity in animal communication, issues relating to defining and classifying multi-modal signals, and particular issues to consider with multimodal (as opposed to multicomponent unimodal) communication are discussed.

TL;DR: It turns out that some seemingly well-established conclusions of sexual selection theory are less general than previously thought.

TL;DR: How sexual selection and natural selection are different mechanisms of evolutionary change is outlined, and it is suggested that this distinction is critical when analyzing the role of sexual selection in speciation.

Is neocortex essentially multisensory
TL;DR: The notion that neocortical operations are essentially multisensory is examined, which forces us to abandon the notion that the senses ever operate independently during real-world cognition.

The use of multiple cues in mate choice
TL;DR: It is suggested that in contrast to this expectation, the use of multiple cues can reduce mate choice costs by decreasing the number of mates inspected more closely or the time and energy spent inspecting a set of mates.
