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 ...

Avoidance Learning: A Review of Theoretical Models and Recent Developments [PDF]
Frontiers in Behavioral Neuroscience, 2015 Avoidance is a key characteristic of adaptive and maladaptive fear. Here, we review past andcontemporary theories of avoidance learning. Based on the theories, experimental findings and clinical observations reviewed, we distil key principles of how ...

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 ...

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.

Dynamic Obstacle Avoidance and Path Planning through Reinforcement Learning
Applied Sciences, 2023 The use of reinforcement learning (RL) for dynamic obstacle avoidance (DOA) algorithms and path planning (PP) has become increasingly popular in recent years. Despite the importance of RL in this growing technological era, few studies have systematically

, 2015 Humans are evolutionary wired to avoid potentially dangerous situations. Such ability allows us to cope with threatening circumstances, ranging from the encounter of animal predators to speeding cars on the highway. Adaptive as it seems in those situations, individuals may sometimes excessively avoid cues or situations even when a threatening outcome ...

Learning Singularity Avoidance [PDF]
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019 With the increase in complexity of robotic systems and the rise in non-expert users, it can be assumed that task constraints are not explicitly known. In tasks where avoiding singularity is critical to its success, this paper provides an approach, especially for non-expert users, for the system to learn the constraints contained in a set of ...

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
