Seasonal variation in reversal learning reveals greater female cognitive flexibility in African striped mice

open access: yesScientific Reports, 2021
Cognitive flexibility describes the ability of animals to alter cognitively mediated behaviour in response to changing situational demands, and can vary according to prevailing environemental conditions and individual caracteristics. In the present study,

Ethical Adversaries: Towards Mitigating Unfairness with Adversarial Machine Learning [PDF]

open access: yes, 2020
Machine learning is being integrated into a growing number of critical systems with far-reaching impacts on society. Unexpected behaviour and unfair decision processes are coming under increasing scrutiny due to this widespread use and its theoretical ...

Dogs Exhibiting High Levels of Aggressive Reactivity Show Impaired Self-Control Abilities

open access: yesFrontiers in Veterinary Science, 2022
Inhibitory control describes a multitude of cognitive processes that prevents an impulsive response and enables a more appropriate behavior in a given situation.

Age-related similarities and differences in brain activity underlying reversal learning [PDF]

open access: yes, 2013
The ability to update associative memory is an important aspect of episodic memory and a critical skill for social adaptation. Previous research with younger adults suggests that emotional arousal alters brain mechanisms underlying memory updating ...

Impulsivity Relates to Multi-Trial Choice Strategy in Probabilistic Reversal Learning

open access: yesFrontiers in Psychiatry, 2022
Impulsivity is defined as a trait-like tendency to engage in rash actions that are poorly thought out or expressed in an untimely manner. Previous research has found that impulsivity relates to deficits in decision making, in particular when it ...

Contrast-reversal abolishes perceptual learning

open access: yesJournal of Vision, 2009
We tested the effects of contrast reversal on perceptual learning in a 10AFC texture identification task. Four groups of subjects performed the task on two consecutive days. One group saw the same textures on both days, whereas three other groups saw novel, rotated (180 deg), or contrast-reversed textures on the second day.

Assessment of Metacognition and Reversal Learning in Parkinson’s Disease: Preliminary Results

open access: yesFrontiers in Human Neuroscience, 2018
Reversal learning (RL) has been widely used for assessment of behavioral adaptation, impulsivity, obsession, and compulsion in healthy controls as well as people suffering from psychiatric and neurological disorders such as Parkinson’s disease (PD ...

Functional neurochemical imaging of the human striatal cholinergic system during reversal learning [PDF]

open access: yes, 2017
Animal studies have shown that acetylcholine (ACh) levels in the dorsal striatum play a role in reversal learning. However, this has not been studied in humans due to a lack of appropriate non-invasive techniques.
