Background: Angiotensin receptor blockade (ARB) has been linked to aspects of aversive learning and memory formation, the prevention post-traumatic stress disorder symptom development. Methods: We investigate influence ARB losartan on Pavlovian conditioning using a probabilistic paradigm. In double-blind, randomised placebo-controlled design, we tested 45 (18 female) healthy volunteers during Baseline session, after application or placebo (Drug session) Follow-up session. On each participants engaged in task where they had predict probability an electrical stimulation every trial while true shock contingencies repeatedly switched between phases high low threat. Computational reinforcement models were used dynamics. Results: Acute administration significantly reduced participants’ adjustment both low-to-high high-to-low threat changes. This was driven by rates group drug session compared baseline. The 50mg dose did not induce reduction blood pressure change reaction times, ruling out general attention engagement. Decreased expectations maintained follow up 24hrs later.Conclusions: study shows that acutely reduces environments. Such decreased may explain previously reported preventive role development anxiety symptoms.

Sports cardiology focuses on athletes' cardiovascular health, yet sudden cardiac death remains a significant concern despite preventative measures. Prolonged physical activity leads to notable adaptations, known as the athlete's heart, which can resemble certain pathological conditions, complicating accurate diagnoses and potentially leading serious consequences such unnecessary exclusion from sports or missed treatment opportunities. Wearable devices, including smartwatches smart glasses, have become prevalent for monitoring health metrics, offering potential clinical applications cardiologists. These gadgets are capable of spotting exercise-induced arrhythmias, uncovering hidden heart problems, crucial information training recovery, minimize exercise-related incidents enhance care. However, concerns about data accuracy actionable value obtained persist. A major challenge lies in integration artificial intelligence with wearables, research gaps remain regarding their ability provide real-time, reliable, clinically relevant insights. Combining wearable devices improve how is managed used cardiology. Artificial intelligence, particularly machine learning, classify, predict, draw inferences collected by revolutionizing patient usage. Despite intelligence's proven effectiveness managing chronic limited its application cardiology, creates critical gap that needs be addressed. This review examines commercially available wearables exploring integrated into technology advance field.

Abstract Striking a balance between individual and social learning is one of the key capabilities that support adaptation under uncertainty. Although intergenerational transmission information ubiquitous, little known about when how newcomers switch from loyally preceding models to exploring independently. Using behavioural experiment, we investigated available demonstrator affects timing becoming independent performance thereafter. Participants worked on 30-armed bandit task for 100 trials. For first 15 trials, participants simply observed choices who had accumulated more knowledge environment passively received rewards demonstrator's choices. Thereafter, could making at any time. We three conditions differing in demonstrator: choice only, reward only or both. Results showed both participants’ strategies stop observational their patterns after independence depended information. generally failed make best use previously subsequent choices, suggesting importance direct communication beyond passive observation better Implications cultural evolution are discussed.

Generalization, defined as applying limited experiences to novel situations, represents a cornerstone of human intelligence. Our review traces the evolution and continuity psychological theories generalization, from origins in concept learning (categorizing stimuli) function (learning continuous input-output relationships), domains such reinforcement latent structure learning. Historically, there have been fierce debates between rule-based mechanisms, which rely on explicit hypotheses about environmental structure, similarity-based leverage comparisons prior instances. Each approach has unique advantages: rules support rapid knowledge transfer, while similarity is computationally simple flexible. Today, these culminated development hybrid models grounded Bayesian principles, effectively marrying precision with flexibility similarity. The ongoing success not only bridges past dichotomies but also underscores importance integrating both for comprehensive understanding generalization.
