Threat perception and behavioral reactivity in response to an acute stressor in infant rhesus macaques.

ABSTRACT: Attentional bias to threat is an adaptive response to the presence of threat and danger in the environment (Haselton et al., 2009; Pollak, 2008). Attentional bias to threat is present in both human and nonhuman primates (e.g., Mandalaywala, Parker, & Maestripieri, 2014) and attentional bias to threat is exacerbated during periods of acute stress in rhesus macaque adults (Bethell et al., 2012a,b). Here, we build on this extant work to assess whether 5-month-old infant rhesus macaques, previously believed to be too young to express attentional bias to threat, might actually demonstrate attentional bias in response to an acute stressor. At approximately 5 months of age, free-ranging rhesus macaque infants on Cayo Santiago, Puerto Rico (N = 44) were briefly separated from their social group an
