Summary: Research suggests that dopamine in the striatum plays a critical role in visual decision-making, encoding visual stimuli and rewarded actions in a lateralized fashion. Contrary to previous beliefs, dopamine signals in the DMS respond to contralateral stimuli and rewarded actions, facilitating associations between specific visual stimuli and actions.

Summary: The functional significance of post-error slowing (PES) in decision-making is still debated, as it is not always adaptive. This study found that the nature of PES is influenced by an individual's speed-accuracy tradeoff policy. The findings suggest that post-error adjustments vary depending on the context in which the task is performed and may affect both the speed of subsequent actions and the extent to which PES is associated with a gain in performance.

Summary: Efficient decision-making requires accounting for sources of uncertainty, and while the nervous system can handle perceptual uncertainty well, it struggles with other types of uncertainty. This article reviews previous studies and presents an example showing how the nervous system accounts for different uncertainties in decision-making.

Summary: Balancing short-term speed and accuracy is crucial for making optimal decisions in the presence of noise. This study demonstrates the importance of long-term learning in the speed-accuracy trade-off and provides a theoretical framework that incorporates learning dynamics. The findings reveal that choosing suboptimal response times to facilitate faster learning can lead to greater total reward, suggesting cognitive control over the learning process.

Summary: This paper explores how human drivers make reliable decisions in uncertain environments. By utilizing an explainable artificial intelligence method and entropy-based measures, it reveals the changes in perceptual uncertainty during the execution of interactive tasks, demonstrating that human drivers actively seek information to reduce perceptual uncertainty and make trustworthy decisions.

Summary: This study trained an artificial neural network using 32 EEG channels to predict errors in perceptual decision-making. By transforming the 2D input data into a 1D feature vector through convolutional procedures, the model achieved high accuracy in predicting perceptual decision-making errors. The findings have significant implications for predicting and preventing human errors in brain-computer interfaces.

Summary: Behavioral evidence suggests that reward prediction errors play a key role in episodic memory acquisition. In a novel task where RPEs were manipulated, fMRI results confirmed that signed RPEs are encoded in the ventral striatum and mediate their effects on episodic memory accuracy. Connectivity between processing areas and the hippocampus and ventral striatum increased with RPE value, supporting their central role in episodic memory formation.

Summary: This study used EEG and behavioral modeling to examine the cognitive and neural dynamics of decision-making in awake and low-alertness states in humans. The results showed that during periods of low alertness, reaction times were slower, attention to the left side of space decreased, and the rate of evidence accumulation was lower. Additionally, there was a delay in the neural signatures distinguishing between left and right decisions and a spatial reconfiguration of neural activity. These findings reveal the mechanisms of cognitive resilience in the face of decreased alertness.

Summary: Post-error slowing (PES) is a phenomenon in human decision-making studies, characterized by an increase in response time for a decision following an error. PES reflects the deployment of executive resources to restore task performance. This study found that PES is influenced by multiple distinct processes, with a significant impact from working memory recruitment.

Summary: In this study, decision-making behaviors and neural mechanisms were investigated using a multifactor gambling task. The results showed that probability and delay both affect decision-making behavior, with probability having a stronger impact. Paradoxical elongation of reaction times occurred in certain conditions, possibly related to strategy switching. Analysis of brain activations and behavioral data suggested the presence of multiple decision strategies.

Summary: The study evaluated the relative benefit of 7T over 3T fMRI for assessing responses evoked in different brain regions by a cognitive task, demonstrating a generally bigger advantage of 7T in subcortical structures. Stronger responses were also found at 7T for easier decisions in dopaminergic midbrain nuclei, in line with reward expectation, showcasing the potential of 7T fMRI in understanding cognitive computations in the human brain.

Summary: Binge-Eating Disorder (BED) involves craving, loss of control, and psychological distress during binge-eating episodes. Neurocognitive dysfunctions contribute to BED onset, maintenance, and treatment response. A comprehensive review of research since 2013 reveals cognitive deficits in several decision-making processes, highlighting the potential for cognitive interventions in BED treatment.
