    The translation of human physiological measures to animals becomes more challenging, and perhaps less appropriate, with increased phylogenetic distance. The nature of invertebrate welfare is debated (e.g., Broom, 2013; Carere et al., 2011; Mason, 2011; Sherwin, 2001), though physiological measures might prove effective in establishing, assessing, and improving welfare among this phyla (Perry and Baciadonna, 2017). One generative approach to resolve these two challenges would be to carry out research that explicitly manipulates parameters that should theoretically influence hedonic, eudaimonic, and social welfare in a given species and assess downstream impact on physiological measures relevant to that species.

  • Towards a comparative science of emotion: Affect and consciousness in humans and animals

    2020, Neuroscience and Biobehavioral Reviews
    Citation Excerpt :

    Naturally, such theories which localize the NCC to the brainstem and other non-cortical regions would suggest an especially sweeping distribution of animal consciousness. For example, Barron and Klein (2016) argue that insect brains share structural and functional similarities to vertebrate midbrains and hence may also confer consciousness (for further discussions of invertebrate consciousness, see also Edelman et al., 2005; Feinberg and Mallatt, 2016; Godfrey-Smith, 2017; Mason, 2011; Mather, 2008; Sherwin, 2001). The above sketch of NCC proposals, and the implications and questions they suggest for animal consciousness, is necessarily incomplete.

  • Consistent individual differences in the behavioural responsiveness of adult male cuttlefish (Sepia officinalis)

    2015, Applied Animal Behaviour Science
    Citation Excerpt :

    Research on individual differences and personality is also prompted by the recent inclusion of “all live cephalopods” in Directive 2010/63/EU on the use of animals for scientific purposes based on “scientific evidence of their ability to experience pain, suffering, distress and lasting harm” (European Parliament and Council of the European Union, 2010). Such an inclusion is not shared by the entire scientific community (e.g. Mason, 2011; Sneddon et al., 2014), as well as by all stakeholders, thus it is instrumental to objectively study new areas that could contribute to its understanding (see Crook et al., 2011 for squid). Personality is one of such aspects, since knowing about individual difference will allow us to tailor the captive environment to the individual, not just to the species (Horvath et al., 2013).

  • Agitated honeybees exhibit pessimistic cognitive biases

    2011, Current Biology
    Citation Excerpt :

    Identifying the best objective measures of negative affect (i.e., emotion) in animals is currently the focus of intense debate [2, 4, 21, 22].
