“…(e.g., Edgar et al, 2015; Hennessy et al, 2009; Kiyokawa, 2015). In the current study, plasma cortisol sharply increased the first day indoors, but the effect was no greater for monkeys tested alone than for those with an affiliative partner.…”

Psychosocial stressors appear to promote the onset of depressive illness through activation and sensitization of inflammatory mechanisms. Here, adult male rhesus monkeys brought from large outdoor social groups to indoor housing for 8 days reliably exhibited a hunched, depressive-like posture. When rehoused indoors a second 8 days about 2 weeks later, monkeys housed alone, but not those with an affiliative partner, showed sensitization of the depressive-like hunched posture. Housing indoors also affected circulating proinflammatory cytokines: IL-1β showed increased responsiveness to immune challenge, and IL-1β and TNF-α showed reduced suppression by dexamethasone. Sensitivity of the anti-inflammatory cytokine IL-10 to immune challenge exhibited a relative increase from the first to the second round of indoor housing in animals housed in pairs, and a relative decrease in animals housed alone. Cytokine levels during indoor housing were positively correlated with duration of depressive-like behavior. Plasma cortisol levels increased but did not differentiate housing conditions or rounds. Results demonstrate a rapid induction and sensitization of depressive-like behavior to indoor individual housing, social buffering of sensitization, and associated inflammatory responses. This paradigm may provide a practical nonhuman primate model for examining inflammatory-mediated consequences of psychosocial stressors on depression and possible social buffering of these effects.

“…There is a long-established body of work on social support, across many taxa, that has suggested affiliative social contact can act as a “buffer” against stress (DeVries, Glasper, & Detillion, 2003). Most of this research has been in mammalian taxa, including guinea pigs (Hennessy, O’Leary, Hawke, & Wilson, 2002; Sachser, Durschlag, & Hirzel, 1998), marmosets (Smith & French, 1997), squirrel monkeys (Gonzalez, Coe, & Levine, 1982), and California mice (Lambert et al, 2001); some recent studies have even found similar results in birds (Edgar et al, 2015). Some of these social support studies have found social buffering in adults to be restricted to pre-existing bonded relationships (Hennessy et al, 2002; Sachser et al, 1998), unlike our subjects.…”

Effects of acute corticosterone treatment on male prairie voles (Microtus ochrogaster): Territorial aggression does not accompany induced social preference.

Corticosterone (CORT) is a stress-related steroid hormone found in vertebrates, and is known to interact with behavior. In the socially monogamous prairie vole Microtus ochrogaster, acute stress and specifically acute CORT administration have been shown to facilitate male social preference for a familiar female, and this effect has been described as facilitation of the monogamous pair bond. It is possible, however, that the effects of stress on social preference may initially represent a short-term coping strategy. Here we test whether the effect of acute CORT administration extends to territoriality, a defining component of the prairie vole monogamous suite of behaviors. Onset of territoriality would provide further support for an induced pair bond, whereas no increase in aggression would suggest an initial coping response. Using acute exogenous CORT injections followed by behavioral trials, we found a facilitation of social preference, but we did not find increased aggression. This result suggests that the social preference that develops in response to CORT is at least in part a coping response rather than facilitation of comprehensive monogamous pair bond behavior. Our results are consistent with previous studies both within prairie voles and across other taxa that suggest that social contact may be involved in the regulation of stress responses.

“…However, there are individual differences across mother hens in their effectiveness as social buffers, with less emotional hens being better at buffering their chicks’ stress reaction (Edgar et al 2015). These findings suggest that there are different “maternal styles” in mother hens which may be based upon differences in personality traits.…”

Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in these areas with other birds and other vertebrates, particularly mammals. My overall conclusion is that chickens are just as cognitively, emotionally and socially complex as most other birds and mammals in many areas, and that there is a need for further noninvasive comparative behavioral research with chickens as well as a re-framing of current views about their intelligence.
