Spontaneous instrumental avoidance learning in social contexts [PDF]
Scientific Reports, 2022 Adaptation to our social environment requires learning how to avoid potentially harmful situations, such as encounters with aggressive individuals. Threatening facial expressions can evoke automatic stimulus-driven reactions, but whether their aversive ...

Diminished reward circuit response underlies pain avoidance learning deficits in problem drinkers [PDF]
NeuroImage: ClinicalIndividuals engaging in problem drinking show impaired proactive pain avoidance. As successful pain avoidance is intrinsically rewarding, this impairment suggests reward deficiency, as hypothesized for those with alcohol and substance misuse ...

Different brain systems support learning from received and avoided pain during human pain-avoidance learning. [PDF]
Elife, 2022 Both unexpected pain and unexpected pain absence can drive avoidance learning, but whether they do so via shared or separate neural and neurochemical systems is largely unknown. To address this issue, we combined an instrumental pain-avoidance learning task with computational modeling, functional magnetic resonance imaging (fMRI ...

Value generalization in human avoidance learning. [PDF]
Elife, 2018 SummaryGeneralization during aversive decision-making allows us to avoid a broad range of potential threats following experience with a limited set of exemplars. However, over-generalization, resulting in excessive and inappropriate avoidance, has been implicated in a variety of psychological disorders.

The role of the hippocampus in avoidance learning and anxiety vulnerability [PDF]
Frontiers in Behavioral Neuroscience, 2014 The hippocampus has been implicated in anxiety disorders and post-traumatic stress disorder (PTSD); human studies suggest that a dysfunctional hippocampus may be a vulnerability factor for the development of PTSD.

Sex Differences in Behavior and Learning Abilities in Adult Rats
Life, 2023 Laboratory rats have excellent learning abilities and are often used in cognitive neuroscience research. The majority of rat studies are conducted on males, whereas females are usually overlooked. Here, we examined sex differences in behavior and tactile

Royal Society Open Science, 2021 Responding appropriately to others' facial expressions is key to successful social functioning. Despite the large body of work on face perception and spontaneous responses to static faces, little is known about responses to faces in dynamic, naturalistic

Animal Welfare, 2023 Hermit crabs (Paguroidea; Latreille 1802) offer great opportunities to study animal behaviour and physiology. However, the animals’ size and sex cannot be determined when they are inside their shell; information crucial to many experimental designs. Here,
