Researchers found individuals with stronger cue sensitivity tend to have harder time updating beliefs, leading to persistent poor decision-making. This association can lead to biased avoidance or favoritism of cues in people with compulsive disorders, addictions, or anxiety.
Researchers at USC Dornsife College of Letters, Arts and Sciences found that empathy can be trained by associating someone's happiness with personal reward. This effect was subtle but meaningful and lasted even when no rewards were involved.
Researchers discovered that sign trackers, which prioritize interacting with cues over waiting for rewards, rely on dopamine in specific brain regions. The study found that inhibiting dopamine prevented rats from learning to sign track, while increasing dopamine did not speed up the process.
A new AI-powered training platform is being developed to simulate pipeline incidents and provide real-world scenarios for pipeline operators. The platform will use artificial intelligence to create a realistic environment where teams can practice handling hazardous conditions and responding to emergencies.
Researchers from Kyoto University and Cambridge University developed a fluorescent dopamine sensor to monitor dopamine signals in primate brains. The study found that dopamine signals varied depending on the location in the striatum, with distinct patterns observed in the anterior putamen and caudate head.
Researchers at Tel Aviv University discovered the brain actively prevents learning both types of memory, leading to confusion. The brain prioritizes one type of learning over the other using a strategy to resolve conflicts.
Salk researchers created tools to study neuropeptides, finding they control the brain's fear response in mice. Neuropeptides are released during a mild stimulus, triggering fear behaviors, which can be reduced by silencing their release.
A team of researchers developed a dynamical model that explains how animals learn over time, contradicting previous theories. The multi-dimensional model shows that learned associations are not mediated solely by strength but by multiple nearly independent pathways.
A novel neurofeedback technique was developed to enhance awareness of mind-wandering, allowing individuals to manage this state more effectively. The study demonstrated significant enhancement in awareness after 20 minutes of neurofeedback, with no rewards or punishments used.
Research by Tohoku University scientists found that contextual fear conditioning alters genes associated with the synapse in microglia, indicating a new mechanism linking microglia and neuronal activity related to fear conditioning. This non-immune communication may play a key role in fear memory consolidation and extinction.
The new AI system uses associative learning to detect similarities in datasets, reducing processing time and computational cost. By leveraging optical parallel processing and light signals, the system can identify patterns and associations more efficiently than conventional machine learning algorithms.
A study of 25 people found that Pavlovian conditioning to an allergen can lead to a placebo allergic reaction in the environment where the allergen was encountered. Sleep consolidation is thought to play a role in this response, according to the authors.
Researchers at Dartmouth College and Harvard Medical School have confirmed that single-cell eukaryote Stentor roeseli can make complex decisions, demonstrating avoidance behavior and a hierarchy of responses to stimulus. The study uses modern technology to recreate an early experiment that was debunked decades ago.
Researchers found that environmental ratings have spillover effects on other companies' behavior, leading to reduced toxic emissions. Rated firms reduce their emissions more when their peers are also rated, while unrated companies in highly regulated industries also change their behavior.
Researchers found that smokers' cravings can be trained to non-smoking related stimuli, and their brains show enhanced activity when exposed to smoking-related cues. This suggests a link between smoking and associative learning, which may contribute to nicotine addiction.
Researchers found that blocking octopaminergic and dopaminergic neurons prevents crickets from recalling rewarding or punishing stimuli. This suggests a 'cognitive' account of classical conditioning applicable to insects.
A new study demonstrates classical conditioning of salivation in cockroaches, revealing sophisticated neural control of autonomic functions. The findings provide a useful model system for studying cellular basis of conditioning in insects.
Neurobiologists found that richer individuals are slower to learn associating a stimulus with financial reward, leading to slower brain responses in reward areas. The study also measured marginal utility of money, finding greater wealth reduces the likelihood of picking up coins on the street.
Scientists used fMRI to study how humans learn to associate brand preferences with rewards, finding key activity in the ventral midbrain and ventral striatum. The study sheds light on the neural mechanisms behind consumer behavior and advertising effectiveness.
