Aping expressions? Chimpanzees produce distinct laugh types when responding to laughter of others.
TLDR
The results of this study indicated that chimpanzees produce laugh-elicited laughter that is distinct in form and occurrence from their spontaneous laughter, providing the first empirical evidence that nonhuman primates have the ability to replicate the expressions of others by producing expressions that differ in their underlying emotions and social implications.Abstract:
Humans have the ability to replicate the emotional expressions of others even when they undergo different emotions. Such distinct responses of expressions, especially positive expressions, play a central role in everyday social communication of humans and may give the responding individuals important advantages in cooperation and communication. The present work examined laughter in chimpanzees to test whether nonhuman primates also use their expressions in such distinct ways. The approach was first to examine the form and occurrence of laugh replications (laughter after the laughter of others) and spontaneous laughter of chimpanzees during social play and then to test whether their laugh replications represented laugh-elicited laugh responses (laughter triggered by the laughter of others) by using a quantitative method designed to measure responses in natural social settings. The results of this study indicated that chimpanzees produce laugh-elicited laughter that is distinct in form and occurrence from their spontaneous laughter. These findings provide the first empirical evidence that nonhuman primates have the ability to replicate the expressions of others by producing expressions that differ in their underlying emotions and social implications. The data further showed that the laugh-elicited laugh responses of the subjects were closely linked to play maintenance, suggesting that chimpanzees might gain important cooperative and communicative advantages by responding with laughter to the laughter of their social partners. Notably, some chimpanzee groups of this study responded more with laughter than others, an outcome that provides empirical support of a socialization of expressions in great apes similar to that of humans.read more

Mirror neurons: from origin to function
TL;DR: It is argued that mirror neurons are forged by domain-general processes of associative learning in the course of individual development, and, although they may have psychological functions, they do not necessarily have a specific evolutionary purpose or adaptive function.

TL;DR: A framework for play signals is provided, showing that they range along two dimensions: one from signals borrowed from other functional contexts to those that are unique to play, and the other from purely emotional expressions to highly cognitive (intentional) constructions.

The social life of laughter
TL;DR: In humans and chimpanzees, social (vol voluntary) laughter is distinctly different from evoked (involuntary) laughter, a distinction which is also seen in brain imaging studies of laughter.

Voice Modulation: A Window into the Origins of Human Vocal Control?
Katarzyna Pisanski,Katarzyna Pisanski,Valentina Cartei,Carolyn McGettigan,Jordan Raine,David Reby +5 more
TL;DR: It is argued that humans' ability to modulate nonverbal vocal features evolutionarily linked to expression of body size and sex provides a largely overlooked window into the nature of this intermediate system between human speech and the less flexible vocal repertoires of other primates.

Convergence of speech rate in conversation predicts cooperation
TL;DR: Gonzales et al. as discussed by the authors showed that spontaneous, temporally based behavioral coordination might facilitate prosocial behavior when the joint cooperative effort is itself perceived as a form of coordination.

TL;DR: Theorists have proposed that men and women and those in various occupational groups should differ in their susceptibility to primitive emotional contagion as discussed by the authors, and they have found that women are more susceptible to emotional contagions than men.
