State-dependent judgement bias in Drosophila : evidence for evolutionarily primitive affective processes

Abstract: Affective states influence decision-making under ambiguity in humans and other animals. Individuals in a negative state tend to interpret ambiguous cues more negatively than individuals in a positive state. We demonstrate that the fruit fly, Drosophila melanogaster, also exhibits state-dependent changes in cue interpretation. Drosophila were trained on a Go/Go task to approach a positive (P) odour associated with a sugar reward and actively avoid a negative (N) odour associated with shock. Trained flies were t… Show more

“…Our findings are in line with previous results in bumblebees (Solvi et al, 2016) that also responded optimistically towards ambiguous cues after receiving a sucrose reward, and with other insects behaving pessimistically after negative experience (Bateson et al, 2011; Deakin et al, 2018; Schlüns et al, 2017). However, caution when interpreting these results as emotions is warranted.…”

“…The judgement bias task has become increasingly important for the study of animal welfare, and has been applied to various species (see Lagisz et al, 2020 for a review), predominantly in captive settings (Bethell, 2015): Farm livestock (Baciadonna & McElligott, 2015), horses (Henry et al, 2017), non-human primates (Bateson & Nettle, 2015;Bethell et al, 2012), dolphins (Clegg et al, 2017), dogs (Burman et al, 2011;Mendl, Brooks, et al, 2010), rodents (Bethell & Koyama, 2015;Nguyen et al, 2020), songbirds (Bateson & Matheson, 2007;Brilot et al, 2009;Matheson et al, 2008;McCoy et al, 2019), fish (Tan, 2017) and also, although very rarely, insects. Honeybees (Apis mellifera carnica) and fruit flies (Drosophila melanogaster) were found to more likely classify ambiguous cues as predictive of a negative outcome after they encountered an artificial predator attack, simulated by vigorous shaking (Bateson et al, 2011;Deakin et al, 2018;Schlüns et al, 2017). Bumblebees (Bombus terrestris) that received an unexpected reward (droplet of sucrose solution) expressed optimism in a judgment bias task and subsequently also recovered faster from a experimentally induced predator attack (Solvi et al, 2016).…”

“…When they played an intermediate tone, rats housed in stressful conditions pressed the lever in significantly fewer trials than non-stressed individuals, suggesting a stronger inclination to expect the unpleasant outcome. Variants of the judgement bias task (JBT) have since been developed for other mammals (e.g., rhesus macaques [ 13 ], Macaca mulatta , sheep [ 14 ], Ovis aries , dogs [ 15 ], Canis lupus familiaris , and bottlenose dolphins [ 16 ], Tursiops truncatus ), birds (e.g., chickens [ 17 ], Gallus gallus domesticus , and starlings [ 18 ], Sturnus vulgaris ), and insects (e.g., fruit flies [ 19 ], Drosophila melanogaster , and honeybees [ 20 ], Apis mellifera ).…”

“…There are a number of strengths of this common currency task: firstly, the task can be performed by diverse species including starlings [ 50 ], honeybees [ 51 ], drosophila [ 52 ] and macaques [ 53 ], and secondly, there is an associated computational model that captures performance on this task [ 45 ]. The computational model used is a version of a drift diffusion model [ 54 , 55 ].…”
