Reversal learning in senescent rats

Behavioural Brain Research, 1985
The ability of old (24 months) and young (3 months) male rats to reverse a previously acquired discrimination was compared in 5 experiments. The old rats did not need more trials to learn a position habit in a T-maze to obtain water reward, but required more trials to reverse the position habit.

Reversal learning: It’s just a phase

Current Biology, 2022
Being able to let go of behaviors that are no longer valuable and adopt actions that achieve the same outcome is fundamental for animal survival. A new study offers clues on the neural mechanisms that allow animals to reverse their behavior as needed.

NMDA receptor dependence of reversal learning and the flexible use of cognitively demanding search strategies in mice

Progress in Neuro-psychopharmacology and Biological Psychiatry, 2019
&NA; Cognitive flexibility helps organisms to respond adaptively to environmental changes. Deficits in this executive function have been associated with a variety of brain disorders, and it has been shown to rely on various concomitant neurobiological ...

Rapid Cue Reversal Learning

2013
Excerpt: Rapid cue reversal learning refers to the ability to alter one’s response after encountering just a few examples of a change in consequences for a behavior. Typically, rapid cue reversal learning is assessed after training on simple discrimination tasks in which an individual is presented with two (or more) stimuli (such as pictures or objects)

Number language and number reversal learning

Journal of Experimental Child Psychology, 1967
Abstract Reversal optional shift performance with cardinal and ordinal number dimensions as relevant was studied in relation to number language knowledge, use of verbal cues, and performance in a coordinate cardinal and ordinal number task with 144 first grade S s in two experiments. The experiments differed in stimulus materials and showed optional

Impulsivity and Reversal Learning

2012
Definition Impulsivity is the propensity to engage in behaviors without adequate forethought. These behaviors are typically approach behaviors aimed at acquiring some kind of reward (e.g., food and money). All major models of human personality include a trait reflecting this propensity, suggesting it to be a core attribute along which people vary ...

Reversal Learning Based on Somatic Markers

2013 Humaine Association Conference on Affective Computing and Intelligent Interaction, 2013
One of the main aspects in the field of Artificial Intelligence is the creation of agents with the ability to learn like human beings do. Based on made experiences humans are able to adapt their behaviour in order to solve tasks. Another important aspect of human decision making is the ability to discard learned behaviour when the usual decisions ...

Discrimination reversal learning in the crayfish

Animal Behaviour, 1967
Summary Nine crayfish failed to show progressive improvement in learning over nine reversals in a two-choice spatial discrimination problem involving a non-correction procedure of training. The results are discussed in their relationship to the habit reversal data on other species.
