Includes pain and sentience.

Fife-Cook, I., Franks, B. 2019. Positive welfare for fishes: Rationale and areas for future study. Fishes 4(2), 31.

Traditional animal welfare paradigms have focused on maintaining physical health and mitigating negative impacts to wellbeing. Recently, however, the field has increasingly recognized the importance of positive welfare (i.e., mental and physical states that exceed...

Heyse, N. C., Brenes, J. C., Schwarting, R. K. W. 2015. Exercise reward induces appetitive 50-kHz calls in rats. Physiology & Behavior 147, 131-140.

Rats express affective states by visible behaviors (like approach or flight) and through different kinds of ultrasonic vocalizations (USV). 50-kHz calls are thought to reflect positive affective states since they occur during rewarding situations like...

Grandin, T. 2018. My reflections on understanding animal emotions for improving the life of animals in zoos. Journal of Applied Animal Welfare Science 21(S1), 12-22.

Scientists are often reluctant to attribute emotions to nonhuman animals that are similar to human emotions. When the author published her early studies, reviewers prohibited the word fear. Fearful behavior had to be described as...

Rørvang, M. V., Christensen, J. W. 2018. Attenuation of fear through social transmission in groups of same and differently aged horses. Applied Animal Behaviour Science 209, 41-46.

Transmission of fear and attenuation of fear within groups of farm animals remain relatively unexplored, despite the importance for human and animal safety. This paper reports the results of two separate experiments, aiming to explore...

Carlone, B., Gazzano, A., Gutiérrez, J. et al. 2018. The effects of green odour on domestic dogs: A pilot study. Applied Animal Behaviour Science 207, 73-78.

Green odour (a mixture of cis-3-hexenol and trans-2-hexenal), similar to cut grass, has been demonstrated to appease subjects of various species (rats, cattle, humans etc.) subjected to different stressful stimuli. The aim of this study...

Paul, E. S., Edgar, J. L., Caplen, G. et al. 2018. Examining affective structure in chickens: valence, intensity, persistence and generalization measured using a Conditioned Place Preference Test. Applied Animal Behaviour Science 207, 39-48.

When measuring animals’ valenced behavioural responses to stimuli, the Conditioned Place Preference (CPP) test goes a step further than many approach-based and avoidance-based tests by establishing whether a learned preference for, or aversion to, the...

Franks, B., Graham, C., Von Keyserlingk, M. A. G. 2018. Is heightened-shoaling a good candidate for positive emotional behavior in zebrafish? Animals 8(9), 152.

Zebrafish, a highly-social species of freshwater fish, are widely studied across many fields of laboratory science including developmental biology, neuroscience, and genomics. Nevertheless, as standard housing for zebrafish typically consists of small and simplistic environments...

Aujnaraina, A. B., Luoa, O. D., Taylor, N. et al. 2018. Effects of exercise and enrichment on behaviour in CD-1 mice. Behavioural Brain Research 342, 43-50.

A host of scholarly work has characterized the positive effects of exercise and environmental enrichment on behaviour and cognition in animal studies. The purpose of this study was to investigate the uptake and longitudinal impact...

Kleefeld, S., Bannerton, K., Kelly, J. 2017. Effect of moderate environmental enrichment on commonly used behavioural tests in rats. Animal Technology and Welfare 16(1), 75-76.

The environment that laboratory animals are housed in should reflect their natural habitats in a manner that can satisfy their innate physiological and behavioural needs. This includes nest building, hiding, exploring and foraging. Providing environmental...
