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.

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. Twenty-seven video recordings were analysed using motion energy ...

Introduction. The article presents a systematic review of psychological research focusing on metacognitive regulation of learning effectiveness through digital educational technologies (DET). Digital technologies are often used in education. Over the past years, self-regulated learning, i.e., the practice of using digital technologies to manage learning activities, has been gaining momentum. However, the specifics of such ...

Rectangularity can be an a priori constraint for the visual system to recover a 3D shape from a 2D image. Two psychophysical experiments (n = 16 each) were conducted to test whether observers are biased to perceive trihedral corners as rectangular and whether this bias is perceptual rather than a response bias. The results of ...

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 ...

Variational Inference is a powerful tool in the Bayesian modeling toolkit, however, its effectiveness is determined by the expressivity of the utilized variational distributions in terms of their ability to match the true posterior distribution. In turn, the expressivity of the variational family is largely limited by the requirement of having a tractable density function. ...
