Summary

My research

My research interests are in the area of animal behaviour and welfare.

I am interested in the links between affective and cognitive processes, in particular the ways in which attention, memory and decision-making both influence and are influenced by affective state. One aim of our current research, in collaboration with psychologist Dr Liz Paul, is to investigate whether affect-induced modulation of decision-making, which leads to so-called 'cognitive bias' in humans, is also observed in animals, and hence can be used as a novel indicator of animal affect (emotion) and welfare.

I am also interested in the evolution and function of affective states, developing new measures of animal emotion and welfare that can be used under field conditions, and understanding more about animal cognition, emotion, personality, and social behaviour with a view to identifying and minimising welfare problems for captive animals.

I also have interests in the influence of early experience and social behaviour (including mother-offspring relations, early husbandry procedures, and 'abnormal behaviours' such as tail-biting in pigs) on behavioural development, an individual's ability to cope with challenge, and animal welfare.

I lead the BBSRC UK Animal Welfare Research Network which is ably managed by Poppy Statham.

 

Michael Mendls' Research

Main projects

BBSRC: Validating inactivity in the home-cage as a depression-like state indicator in mice. With Carole Fureix (Co-I Plymouth), we (Anna Davies, Liz Paul, Amanda Deakin, Mike Mendl (PI)) are investigating the use of wakling inactivity as a spontaneous behaviour measure of depression like states in mice. 

UFAW: Developing new thermographic methods to assess emotional valence by measuring thermal lateralization. We (Helena Telkanranta, Liz Paul, Becky, Whay, Mike Mendl (PI)) are investigating the use of thermal imaging as an indicator of affective valence, arousal and welfare in cattle and chickens.

BBSRC: Can social buffering pheromones be used to reduce stress? We (PI: Pete Brennan (Physiology, Pharmacology & Neuroscience); Co-Is: Mike Mendl, Emma Robinson (Physiology, Pharmacology & Neuroscience), Stafford Lightman (Laboratories for Integrative Neuroscience & Endocrinology); Researcher: Jen Davies) are studying whether social buffering perhomones produced by mice can be used to reduce stress and hence enhance welfare.

Research findings

  • Development of a new technique for measuring biases in decision-making under ambiguity ('judgement biases') in non-human animals
  • Affect-induced judgement biases appear to be reliable new indicators of animal emotion and welfare
  • Affect-induced judgement biases have now been observed in rats, humans and dogs. Other labs have used our technique to demonstrate them in rodents, sheep, starlings, rhesus monkeys, pigs, and honeybees
  • Sensitivity to reward loss may also be a useful new indicator of animal emotion and welfare
  • 'Discrete' and 'dimensional' theories of emotion can be integrated to provide a functional view of animal emotion and the role of affect in altering decision-making
  • The influence of threat (e.g. probability of predation) on optimal decision-making by combined fast/inaccurate and slow/accurate mechanisms can be modelled
  • Early experience of stressful husbandry effects may have lifelong consequences in sheep
  • Pigs can adjust their foraging behaviour to avoid their knowledge being exploited depending on whom they are foraging with

Biography

Teaches
BVSc Veterinary Sciences
MSc Global Wildlife Health and Conservation

Mike obtained his PhD in animal behaviour at Cambridge University. He then took a Royal Society European Research Fellowship to continue his work on behavioural development at Groningen University in the Netherlands, before returning to work at Cambridge University Vet School where he moved into the field of applied animal behaviour and welfare. He subsequently took up a position as a Behavioural Scientist at the Scottish Agricultural College in Edinburgh, continuing his work on pig behaviour and welfare, and then moved to Bristol University Vet School where he is now Professor of Animal Behaviour and Welfare and Head of the Bristol Animal Welfare & Behaviour Group, and has previously been Deputy Head of School (Research). He is also lead of the UK Biotechnology and Biological Sciences Research Council Animal Welfare Research Network. His current research interests are in the study of cognition, emotion, and social behaviour in domestic animals, with a view to using this information to improve animal welfare. Together with Dr Liz Paul, he developed a novel ‘cognitive bias’ approach to the assessment of animal emotions which draws on theory and findings from human psychology and cognitive neuroscience. He and Liz received the 2013 inaugural International Society for Applied Ethology Creativity Award, and the Alice Richie Trust Memorial Fund Award for their work in this area. Mike was awarded the UFAW Medal in 2014 for his contributions to animal welfare science, and the RSPCA/BSAS Award for Innovative Developments in Animal Welfare in 2015. Mike also works on more applied animal welfare issues, with current interests in the relationship between housing and husbandry procedures and the health and welfare of farm, laboratory and zoo animals, and chronic pain conditions in domestic dogs.
