Dorsolateral prefrontal cortex plays causal role in probability weighting during risky choice
Scientific Reports. 2022. Vol. 12. No. 1. Article 16115.
In this study, we provide causal evidence that the dorsolateral prefrontal cortex (DLPFC) supports the computation of subjective value in choices under risk via its involvement in probability weighting. Following offline continuous theta-burst transcranial magnetic stimulation (cTBS) of the DLPFC subjects (N = 30, mean age 23.6, 56% females) completed a computerized task consisting of 96 binary lottery choice questions presented in random order. Using the hierarchical Bayesian modeling approach, we then estimated the structural parameters of risk preferences (the degree of risk aversion and the curvature of the probability weighting function) and analyzed the obtained posterior distributions to determine the effect of stimulation on model parameters. On a behavioral level, temporary downregulation of the left DLPFC excitability through cTBS decreased the likelihood of choosing an option with higher expected reward while the probability of choosing a riskier lottery did not significantly change. Modeling the stimulation effects on risk preference parameters showed anecdotal evidence as assessed by Bayes factors that probability weighting parameter increased after the left DLPFC TMS compared to sham.

Bacterial chromosomes are tightly packed in the cells due to interactions with specific nucleoid-associated proteins. Among them, the IHF protein draws attention due to its presumed influence on intracellular crystallization processes, leading to bacterial resistance to drugs. The crystal structure of the IHF heterodimer is known only in complex with a short DNA fragment, whereas ...

The current exploratory study aims to reveal identity gaps and interpersonal communication strategies used by Russians to overcome social identity crises. Based on previous research, we assume that many Russians who live both in Russia and abroad face ethnic and national identity threats and experience different social identity crises due to recent geopolitical events.

Musical training has a significant impact on brain organization, leading to functional and structural
adaptations that enhance auditory, visual, motor, and cognitive processes. This study investigates how
extensive musical training shapes functional brain connectivity by comparing professional musicians and
non-musicians. Using EEG phase-locking value (PLV) analysis, we examined neural synchronization across
alpha, beta, and gamma frequency ranges during music ...

Abstract
Context and relevance. In the context of accelerated urbanization and a growing disconnect from the natural
environment, there is increasing interest in biophilic attitudes — a system of stable views, beliefs, and
evaluations that reflect a person’s relationship with living nature and shape their psychological well-being and
environmentally responsible behavior. Existing tools for their measurement, such as the ...

Meditation offers a naturalistic paradigm for studying introspection, yet the neural dynamics of advanced tantric practices remain largely unexplored. Buddhist Highest Yoga Tantra (BHYT) comprises a sequence of eight dissolution stages culminating in the “clear light” state. We recorded EEG during eyes-closed BHYT meditation performed in monasteries and hermitages (51 sessions from 36 male practitioners; ...

Context and relevance. The influence of the environment on psychological well-being has been studied in a wide variety of contexts, including workplaces, schools, healthcare facilities, and digital spaces. However, the psychological well-being of university faculty, particularly in relation to their connection to the university environment in the wide sense, remains virtually unrepresented in psychological research. ...

Resistance to change remains central to psychoanalytic practice: Patients often maintain dysfunctional
beliefs and relational patterns even when they recognize their destructive nature. While psychoanalysis has
richly described resistance as a defense against painful affect and threats to internal object relations, the
process-level dynamics through which resistance persists over time have remained incompletely articulated.

Personality psychology owes much of its cumulative success to self- and informant-report
assessment. Report-based trait constructs are reliable, replicable, predictive, and useful for organising a
wide range of findings. This paper argues that their success should be understood not only
methodologically, but also theoretically. I propose the attributional model of personality reporting,
according to which self- and informant-reported traits are ...

Background:
Numerous studies have shown that indigenous populations experience poorer health outcomes compared to people with other backgrounds. However, the interpretation of these disparities remains challenging due to differences in living conditions and social environments, as well as by potential measurement-related biases. Little is known about whether the underlying mechanisms of mental health outcomes differ between ...

Cognitive distortions are routinely described in cognitive-behavioral (CBT) and rational-emotive behavior (REBT) therapies as “errors in logic” or “illogical thinking.” While this terminology is pedagogically convenient, it often obscures a crucial conceptual distinction between violations of logical inference and problems related to the justification, scope, or evaluative force of belief content. In this paper, we do not ...

Interpersonal synchrony is increasingly conceptualized not as a static marker of rapport but as a dynamic, context-sensitive process that fluctuates across interactional phases to serve distinct relational functions. This study examined whether movement synchrony—absolute, non-absolute, client-leading, and counsellor-leading—was associated with therapeutic alliance in naturally occurring counselling sessions.

The theory of cognitive dissonance (CD) is tightly linked with studies of the process of making complex decisions. In particular, CD is manifest within the framework of the “free choice paradigm” consisting of reassessment of alternatives as a result of choosing between two similar alternatives via the motivation to reduce internal conflict. The mechanisms of ...

More than a decade of neuroimaging and brain stimulation studies point to a crucial role for the right dorsolateral prefrontal cortex (rDLPFC) in prosocial behavior. The intuitive prosociality model postulates that the rDLPFC controls intuitive prosocial behavior, whereas the reflective model assumes that the rDLPFC controls selfish impulses during prosocial behavior. The intuitive prosociality model ...

Tensor decomposition methods have recently proven to be efficient for compressing and accelerating neural networks. However, the problem of optimal decomposition structure determination is still not well studied while being quite important. Specifically, decomposition ranks present the crucial parameter controlling the compression-accuracy trade-off. In this paper, we introduce MARS - a new efficient method for ...
