Computational animal welfare: towards cognitive architecture models of animal sentience, emotion and wellbeing.

ABSTRACT: To understand animal wellbeing, we need to consider subjective phenomena and sentience. This is challenging, since these properties are private and cannot be observed directly. Certain motivations, emotions and related internal states can be inferred in animals through experiments that involve choice, learning, generalization and decision-making. Yet, even though there is significant progress in elucidating the neurobiology of human consciousness, animal consciousness is still a mystery. We propose that computational animal welfare science emerges at the intersection of animal behaviour, welfare and computational cognition. By using ideas from cognitive science, we develop a functional and generic definition of subjective phenomena as any process or state of the organism that exists from the first-person perspective and cannot be isolated from the animal subject. We then outline a general cognitive architecture to model simple forms of subjective processes and sentience. This includes evolutionary adaptation which contains top-down attention modulation, predictive processing and subjective simulation by re-entrant (recursive) computations. Thereafter, we show how this approach uses major characteristics of the subjective experience: elementary self-awareness, global workspace and qualia with unity and continuity. This provides a formal framework for process-based modelling of animal needs, subjective states, sentience and wellbeing.

Project description:BACKGROUND:Male piglets are surgically castrated at a young age primarily to prevent pork meat from being tainted with boar taint, an offensive taste and odor that can be present in uncastrated male pigs. The practice of surgical castration is considered to be both stressful and painful for the piglets, and is therefore under scrutiny due to animal welfare concerns. Rearing of intact males or vaccination against boar taint (immunocastration) are two potential alternatives to surgical castration, but in order to successfully implement either of these alternatives, consumer acceptance of the different methods must be taken into consideration as it will be central for future sales of pork products. A consumer survey mapping Norwegian consumers' attitudes toward piglet castration was conducted to explore whether the consumers' position regarding castration has changed since an almost identical study was completed in 2008. RESULTS:The internet-based survey found that Norwegian consumers are comfortable with the current practice of surgical castration with anesthesia, but also that they are open to the alternative method of vaccination against boar taint. When provided additional information stating that vaccination against boar taint may not be able to reduce boar taint to the levels that castration with anesthesia does, consumer skepticism towards vaccination increased. When evaluating castration methods, animal welfare was the most important influencing factor. Since the original survey from 2008, animal welfare was also the single factor that has increased the most among a set of assessment criteria when purchasing pork products. CONCLUSION:Norwegian consumers regard animal welfare as an important factor both when purchasing pork products and when evaluating different methods of castration, and animal welfare as a factor has increased in importance since the initial survey in 2008. Although the current practice of castration using local anesthesia is still widely accepted among consumers, the acceptance of today's method has declined since the original survey in 2008.

Project description:The Five Freedoms have had major impact on animal welfare thinking internationally. However, despite clear initial statements that the words 'freedom from' should indicate 'as free as possible from', the Freedoms have come to be represented as absolute or fundamental freedoms, even rights, by some animal advocate and other groups. Moreover, a marked increase in scientific understanding over the last two decades shows that the Freedoms do not capture the more nuanced knowledge of the biological processes that is germane to understanding animal welfare and which is now available to guide its management. For example, the named negative experiences of thirst, hunger, discomfort and pain, and others identified subsequently, including breathlessness, nausea, dizziness, debility, weakness and sickness, can never be eliminated, merely temporarily neutralised. Each one is a genetically embedded element that motivates animals to behave in particular ways to obtain specific life-sustaining resources, avoid or reduce physical harm or facilitate recovery from infection or injury. Their undoubted negativity creates a necessary sense of urgency to respond, without which animals would not survive. Also, the temporary neutralisation of these survival-critical affects does not in and of itself generate positive experience. This questions the commonly held assumption that good animal welfare will result when these internally generated negative affects are minimised. Animals may also experience other negative affects that include anxiety, fear, panic, frustration, anger, helplessness, loneliness, boredom and depression. These situation-related affects reflect animals' perceptions of their external circumstances. Although they are elicited by threatening, cramped, barren and/or isolated conditions, they can often be replaced by positive affects when animals are kept with congenial others in spacious, stimulus-rich and safe environments which provide opportunities for them to engage in behaviours they find rewarding. These behaviours may include environment-focused exploration and food acquisition activities as well as animal-to-animal interactive activities, all of which can generate various forms of comfort, pleasure, interest, confidence and a sense of control. Animal welfare management should aim to reduce the intensity of survival-critical negative affects to tolerable levels that nevertheless still elicit the required behaviours, and should also provide opportunities for animals to behave in ways they find rewarding, noting that poor management of survival-critical affects reduces animals' motivation to utilize such rewarding opportunities. This biologically more accurate understanding provides support for reviewing the adequacy of provisions in current codes of welfare or practice in order to ensure that animals are given greater opportunities to experience positive welfare states. The purpose is to help animals to have lives worth living, which is not possible when the predominant focus of such codes is on survival-critical measures. Finally, an updated characterisation of animal welfare that incorporates this more accurate understanding is presented.
