Primate vocal communication is commonly studied in order to illuminate the evolutionary origins of human speech. Consequently, the literature has focused primarily on ultimate explanations, leaving proximate explanations of primate vocal communication understudied. To remedy this, I appropriate theory surrounding emotional contagion, a rudimentary form of empathy, to explore communication according to the following model: a caller’s affect is represented vocally and is thus perceived by a listener, in whom a similar affect is induced. To test the applicability of this model to natural systems, howler monkeys (Alouatta pigra and A. palliata) were exposed to playbacks of high and low call rates, representing high and low “caller” arousal, respectively. The responses of 12 howler groups to these stimuli were measured via several behavioral variables including alertness, movement, and vocalization, as well as roar rate and duration. Respondents did not exhibit significant between-trial differences in alertness, movement, timing of calling bouts, or roar rate, but did respond to high-rate stimuli with significantly longer roars. This result suggests that, although not sufficient to evoke differences in some behaviors, high-rate playbacks did indeed induce greater arousal in listeners. Emotional contagion therefore appears to be a probable underlying mechanism of calling in howler monkeys. Further research is needed to assess the applicability of emotional contagion to other primate communication systems.
