Summary: This paper investigates the speed-accuracy tradeoff in decision making and compares the threshold hypothesis and the gain modulation hypothesis. It finds that the threshold hypothesis is qualitatively consistent with behavioral data, while the gain modulation hypothesis is not. The study also shows that interference from alpha oscillations can enhance the discriminatory power of the decision system, but slows down the decision process. Additionally, lower amplitude alpha oscillations result in an increase in baseline firing rate and the speed of neuronal integration.

Summary: Road boundary detection is crucial for autonomous vehicle localization and decision-making, especially when faced with challenges such as obstacle occlusions and large road curvature in structured environments. The proposed LiDAR-based method utilizes a speed and accuracy tradeoff approach, showing real-time performance and effectiveness in detecting road boundaries under various road conditions.

Summary: This article proposes a resource-efficient dynamic network called RepHAR for low-cost hardware-constrained human activity recognition tasks. RepHAR achieves a trade-off between speed and accuracy by combining multibranch topologies and structured reparameterization techniques. Experimental results on four publicly available datasets demonstrate the effectiveness of the proposed method. RepHAR runs 72% faster than the multibranch CNN model on the embedded Raspberry Pi, showcasing its usefulness and practicality. Our model and codes will be released soon.

Summary: The speed-accuracy tradeoff (SAT) makes psychophysical data difficult to interpret. A Bayesian adaptive SAT method was developed for a quick estimation of SAT function (SATf), but further extensions and experimental validation are needed. An improved method for measuring SATfs for multiple task conditions concurrently was proposed, which showed high agreement with conventional trials in a psychophysical experiment.

Summary: This article focuses on adaptive motion generation of fast goal-oriented motion on the musculoskeletal system by implementing the speed-accuracy tradeoff in a hierarchical motion learning framework. By introducing Fitts' Law and an improved policy gradient algorithm, the proposed muscle co-contraction policy is suggested to promote general cooperation between flexor and extensor muscles. The algorithm demonstrates efficient training and the best performance in adaptive motion generation among other reinforcement learning algorithms on the musculoskeletal model.

Summary: Most psychological experiments measure cognitive function by response time and accuracy to stimuli, with SAT paradigms integrating these factors. Practical limitations of lengthy SAT experiments require more efficient techniques, such as Bayesian adaptive estimation, which proved highly efficient and robust in estimating SAT functions accurately and precisely.

Summary: With the rise of information volume, it has become more crucial than ever to analyze and retrieve vast data. The clustering method is one of the main techniques that can be beneficial in this aspect, aiming to classify objects with similar features in the same cluster. The k-means algorithm is widely used but its performance can be affected by the selection of initial clusters, which the proposed method in this paper addresses to improve accuracy and reduce iteration. Comparing with the Chithra and Reverse Nearest Neighbor (RNN) search approaches, the proposed method showed better clustering accuracy and higher convergence speed.

Summary: The study highlights the trade-off between speed and accuracy in decision-making tasks, with participants exhibiting a strong accuracy bias leading to oversampling. Despite manipulations to underline the importance of speed, participants failed to overcome the accuracy bias, suggesting a conspicuous metacognitive deficit.

Summary: The study found that as walking speed increased, stepping accuracy decreased, with VE and RMSE linearly growing. CE varied based on inter-target spacing, with targets being overshot for shorter distances and undershot for longer distances. The impact of different inter-target spacings on stepping accuracy was more pronounced at faster speeds.

Summary: The current study investigates whether faster recognition memory errors are more difficult to correct, and if this pattern applies to different types of errors. The results suggest that slower miss responses are more likely to be corrected than faster misses, and there were no accuracy differences between slower and faster false alarms. These findings have important implications for understanding the processes underlying memory retrieval errors.

Summary: This study explored the interrelations between mathematics anxiety, metacognition, and mathematical decision-making using an experimental task. Findings suggest that prospective confidence in decision-making is based on easily available cues, while anxiety negatively relates to overall confidence and positively relates to metacognitive efficiency. Understanding these relationships is important for addressing mathematics anxiety and the global demand for STEM workers.

Summary: Human cognition is characterized by the ability to adaptively produce precise spatiotemporal sequences given a certain context. Existing neural network models fail to account for these properties due to the limitation of storing sequence and timing information in the same neural network weights. The ACDC model introduced in this study modularly stores sequence and timing information in distinct loci of the network, enabling a wide range of temporal properties and flexible learning and performance abilities.

Summary: The authors find that current measures of metacognition are confounded with response caution and propose an alternative dynamic measure. They show a relationship between response caution and the popular measure of metacognition, M-ratio. Additionally, they demonstrate that using a dynamic measure, v-ratio, can avoid the impact of the speed-accuracy tradeoff in metacognition assessment.

Summary: Considerable evidence suggests that the dorsolateral prefrontal cortex (DLPFC) plays a crucial role in hierarchical learning. This study investigated the causal relationship between frontal theta oscillations and hierarchical learning. The findings show that theta stimulation can modulate the low-level learning rate and that environmental features may influence the effect of theta stimulation.

Summary: This study investigates the cognitive and computational mechanisms underlying the influence of Pavlovian cues on instrumental behavior in OCD patients and healthy controls. The results indicate a weaker Pavlovian influence on instrumental behavior in OCD patients, especially when negative cues associated with punishment are present. This study provides deeper insight into our understanding of deficits in OCD from the perspective of Pavlovian influences on instrumental behavior and may have implications for OCD treatment modalities focused on reducing compulsive behaviors.

Summary: The standard approach of carrying out a goodness-of-recovery study to determine the amount of data needed for useful parameter estimations from a computational model may not always be optimal. This paper proposes a novel approach using a generalized concept of statistical power and a Python-based toolbox to determine the required data size for parameter estimates. Simulations indicate that a high number of trials per person is necessary for high-powered studies in a specific computational model.

Summary: In this study, a data-driven approach was used to reanalyze a task involving coffee and tea making, revealing the involvement of the inferior-temporal gyrus and lateral prefrontal cortex in maintaining temporal and contextual information for hierarchically organized action sequences. Additionally, temporal information appears to be more strongly encoded in areas over the left hemisphere.
