An integrative and functional framework for the study of animal emotion and mood (2010, background): “2010), sheep (Doyle et al. 2010), starlings (Bateson & Matheson 2007; Matheson et al.”
Cognitive bias in a non-human primate: husbandry procedures influence cognitive indicators of psychological well-being in captive rhesus macaques (2012, background): “Other studies have found significant effects for Pi, the intermediate 383 probe (dogs showing separation-related behaviour: Mendl et al 2010b; sheep following 384 physical restraint and release: Doyle et al 2010a).”
Sheep exhibit a positive judgement bias and stress-induced hyperthermia following shearing (2011, unknown): “Each group contained equal numbers of animals trained to right and left positive corners and this was also balanced for the previous treatments of Doyle et al. (2011). Sheep were tested for judgement bias following treatment in two cohorts (n=6 control and n=6 shorn animals) on two consecutive days.”
The Use of Judgement Bias to Assess Welfare in Farm Livestock (2015, methodology): “In particular, some studies (Doyle et al 2010; Sanger et al 2011; Verbeek et al 2014a) used an acute stressor (3 min per week), whereas others (Doyle et al 2011a; Destrez et al 2012) employed a chronic stressor lasting 3 or 4 weeks.”
Environmental enrichment induces optimistic cognitive bias in rats (2011, background): “We also showed that rats responded faster as training progressed (exiting tunnel, choosing bowl, ﬁ nding correct bowl), indicating that they were learning the task,andimportantly,thattherewasnoevidenceofextinctionwhen unreinforced trials were introduced (see Brilot et al. 2010; Doyle et al. 2010).”
Resilience in farm animals: biology, management, breeding and implications for animal welfare (2016, methodology): “as demonstrated in sheep (Doyle et al. 2010) and as described in more detail in Section 2.”
