A novel emotional and cognitive approach to welfare phenotyping in rainbow trout exposed to poor water quality
Contributor(s):: Colson, V., Mure, A., Valotaire, C., Le Calvez, J. M., Goardon, L., Labbé, L., Leguen, I., Prunet, P.
Recent scientific evidence for fish sentience has stressed the need for novel sentience-based detection tools of fish welfare impairment in commercial farms. In order to mimic a well-characterised stress situation, rainbow trout (Oncorhynchus mykiss) were exposed to poor water quality (hypoxia...
Does the anticipatory behaviour of chickens communicate reward quality?
Contributor(s):: McGrath, Nicky, Burman, Oliver, Dwyer, Cathy, Phillips, Clive J. C.
The anticipatory behaviour of animals has been credited with enabling scientists to more closely infer what an animal wants. From a welfare perspective, this knowledge could improve how we care for animals under our management, as information about how animals prioritise rewarding items may guide...
Can clicker training facilitate conditioning in dogs?
Contributor(s):: Chiandetti, Cinzia, Avella, Silvia, Fongaro, Erica, Cerri, Francesco
In the attempt to verify clicker training efficacy in shaping dogs’ novel behaviours, we studied 51 domestic dogs. Learning was evaluated in three different conditions: when the primary reinforcer (food) was presented in association with (a) a clicker; (b) a spoken word, a condition absent in...
Effect of odorant pre-exposure on domestic dogs' sensitivity on an odorant detection task
Contributor(s):: Hall, Nathaniel J., Smith, David W., Wynne, Clive D. L.
Although dogs are widely trained and deployed for odor detection work, relatively little research has investigated procedures that may more efficiently train or increase detection performance. Prior research in rodents and humans suggests that odorant exposure may enhance sensitivity to that...
Taste overshadows less salient cues to elicit food aversion in endangered marsupial
Contributor(s):: Kelly, Ella, Phillips, Ben L., Webb, Jonathan K.
Conditioned taste aversion is an emerging conservation tool that can be used to limit inter-species conflict, for example decreasing predation on endangered species, or limiting the consumption of invasive toxic prey. Typically, managers wish to elicit an aversion that will be associated with...
Pen trial of estrogen-induced conditioned food aversion to eggs in raccoons (Procyon lotor)
Contributor(s):: Dueser, Raymond D., Martin, Joel D., Moncrief, Nancy D.
Aversive conditioning is a promising but unproven non-lethal approach to reducing mammalian depredation on the eggs of ground-nesting birds, terrapins and sea turtles. This research tested the efficacy of oral estrogen concealed in a bland carrier as an aversive agent for wild-caught raccoons...
An Evaluation of Respondent Conditioning Procedures to Decrease Barking in an Animal Shelter
| Contributor(s):: Steven Wade Payne, Kian S Assemi
A common problem behavior in animal shelters is excessive noise from barking, which can regularly exceed 100dBs. Noise levels in animal shelters are correlated with increased stress in dogs, which may lead to increased problem behavior and a decrease in adoption. The purpose of the...
Applying Behavioral Conditioning to Identify Anticipatory Behaviors

Bottlenose Dolphins' (Tursiops truncatus) Theory of Mind as Demonstrated by Responses to their Trainers' Attentional States
| Contributor(s):: Masaki Tomonaga, Yuka Uwano
The present study examined the ability of dolphins to follow the gestural signs presented by humantrainers in various attentional states in order to understand the social cognition of dolphins. Thehuman trainers enacted the gestural signs by orienting their bodies and heads in different...

Dogs' body language relevant to learning achievement
| Contributor(s):: Hasegawa, M., Ohtani, N., Ohta, M.
The facial expressions and body postures of dogs can give helpful information about their moods and emotional states. People can more effectively obedience train their dogs if we can identify the mannerisms associated with learning in dogs. The aim of this study was to clarify the dog's body...
African elephants ( Loxodonta africana) can detect TNT using olfaction: implications for biosensor application
| Contributor(s):: Miller, A. K., Hensman, M. C., Hensman, S., Schultz, K., Reid, P., Shore, M., Brown, J., Furton, K. G., Lee, S.
The impact of war on local wildlife can be devastating, the effects of which are often felt well beyond the terminus of the initial threat. In areas where wildlife experiences unrestricted movement through previously affected zones, residual, unexploded landmines present a significant and...
Social learning in dog training: the effectiveness of the Do as I do method compared to shaping/clicker training
| Contributor(s):: Fugazza, C., Miklosi, A.
Dog training methods traditionally rely on individual learning (mainly operant conditioning). Yet dogs are adept in acquiring information socially and are able to imitate humans. Dogs' predisposition to learn socially has been recently introduced in dog training with the Do as I do method. With...

Development of a standard test to assess negative reinforcement learning in horses
| Contributor(s):: Ahrendt, L. P., Labouriau, R., Malmkvist, J., Nicol, C. J., Christensen, J. W.
Most horses are trained by negative reinforcement. Currently, however, no standardised test for evaluating horses' negative reinforcement learning ability is available. The aim of this study was to develop an objective test to investigate negative reinforcement learning in horses. Twenty-four...
Pavlovian conditioning enhances resistance to disruption of dogs performing an odor discrimination

Does temperament affect learning in calves?
| Contributor(s):: Webb, L. E., Reenen, C. G. van, Jensen, M. B., Schmitt, O., Bokkers, E. A. M.
The aim of the study was to investigate how temperament affects learning ability in calves. Nine two-month-old Holstein-Friesian bull calves were subjected to four challenge tests: novel object (NOT), novel environment (NET), social isolation (SIT), and social isolation with a novel environmental...
Effect of odor preexposure on acquisition of an odor discrimination in dogs
| Contributor(s):: Nathan Hall, David Smith, Clive Wynne
In two experiments we investigated the impact of odor pre-exposure treatments on the acquisition of an olfactory discrimination in dogs. In the first experiment four groups of dogs were each given five days odor-exposure treatment prior to discrimination training. Dogs in the exposure group were...
