“…It is apparently the combination of tufts and foreleg tapping that attracts predator attention. This supports earlier hypotheses that decorative tufts on the forelegs of S. ocreata function as amplifiers or attention signals (Hasson, 1991(Hasson, , 1997 increasing the efficacy of the leg-tapping display (McClintock and Uetz, 1996;Scheffer et al, 1996;Hebets and Uetz, 2000). Hebets and Uetz (2000) found a correlation between the presence of decorations and pigmentation on the forelegs of Schizocosa species males and the level of visual display they exhibited.…”

“…Hoi & Griggio 2008;Kingma et al 2008;McGraw 2008;Galván & Møller 2009). The honesty of these signals would be mediated by the relative cost that signallers experience during the trait production or during its maintenance (Hasson 1997;Alonso-Alvarez et al 2009). This, however, should also depend on environmental conditions.…”

The expression of melanin-based plumage is separately modulated by exogenous oxidative stress and a melanocortin

Melanin-based traits involved in animal communication have been traditionally viewed as occurring under strict genetic control. However, it is generally accepted that both genetic and environmental factors influence melanin production. Medical studies suggest that, among environmental factors influencing melanization, oxidative stress could play a relevant role. On the other hand, genetic control would be exerted by the melanocortin system, and particularly by the alpha-melanocyte-stimulating hormone (a-MSH), which triggers the production of eumelanins (black pigments). To determine how the melanocortin system and an exogenous source of oxidative stress interact in the expression of melanin-based plumage, developing red-legged partridges (Alectoris rufa) were manipulated. Some partridges were injected with a-MSH, while other birds received a pro-oxidant molecule (diquat) in drinking water. Controls and birds receiving both treatments were also studied. Both a-MSH-and diquat-treated individuals presented larger eumelanin-based traits than controls, but a-MSHþdiquat-treated birds showed the largest traits, suggesting that oxidative stress and melanocortins promote additive but independent effects. Diquat also induced a decline in the level of a key intracellular antioxidant (glutathione), which is associated with high expression of eumelanin-based signals in other bird species. Some scenarios for the evolution of melanin-based traits in relation to oxidative stress are proposed.

“…Yet, observation of daily social functioning or casual corpus analyses shows that this selection represents only a small proportion of the broad spectrum of emotions that support complex social interactions (Cunningham, Kleiner, Bülthoff, & Wallraven, 2004). In analogy to language (Fay, Garrod, Roberts, & Swoboda, 2010) and as highlighted above, facial expressions of emotion likely evolved from a simpler set of expressive patterns that communicated a small set of relevant categories (e.g., approach, avoid, threat) into a more numerous and complex set of facial expressions designed to support more diverse communication needs (e.g., irritation, skepticism, anxiety; Darwin, 1999Darwin, /1872Hasson, 1997;Hebets & Papaj, 2005;Maynard Smith & Harper, 1995). As with the restricted exploration of AU patterns just discussed, restricting investigation to few emotion categories limits knowledge of facial expressions of emotion to a small set of selected emotion categories and their recognition.…”

As a highly social species, humans generate complex facial expressions to communicate a diverse range of emotions. Since Darwin’s work, identifying among these complex patterns which are common across cultures and which are culture-specific has remained a central question in psychology, anthropology, philosophy, and more recently machine vision and social robotics. Classic approaches to addressing this question typically tested the cross-cultural recognition of theoretically motivated facial expressions representing 6 emotions, and reported universality. Yet, variable recognition accuracy across cultures suggests a narrower cross-cultural communication supported by sets of simpler expressive patterns embedded in more complex facial expressions. We explore this hypothesis by modeling the facial expressions of over 60 emotions across 2 cultures, and segregating out the latent expressive patterns. Using a multidisciplinary approach, we first map the conceptual organization of a broad spectrum of emotion words by building semantic networks in 2 cultures. For each emotion word in each culture, we then model and validate its corresponding dynamic facial expression, producing over 60 culturally valid facial expression models. We then apply to the pooled models a multivariate data reduction technique, revealing 4 latent and culturally common facial expression patterns that each communicates specific combinations of valence, arousal, and dominance. We then reveal the face movements that accentuate each latent expressive pattern to create complex facial expressions. Our data questions the widely held view that 6 facial expression patterns are universal, instead suggesting 4 latent expressive patterns with direct implications for emotion communication, social psychology, cognitive neuroscience, and social robotics.
