Summary: This study investigates the role of attention in memory for disgusting facial expressions. Contrary to previous beliefs, attention was found to have a limited role in the memory advantage of these expressions. Disgusted faces were better remembered than neutral faces, indicating that attention is not crucial for facial expression memory.

Summary: This paper proposes a face perception based coding scheme to improve the visual quality of face regions in UHD videos. A tailored face perception model is used to locate face regions accurately and quickly. A face perception map is generated based on a hierarchical mapping algorithm, which is employed to optimize the encoding process. Experimental results show that the proposed method can significantly improve the quality of face regions while causing slight quality decline in other parts of the frame.

Summary: Emotions have a significant impact on time perception, with positive emotions speeding up perception and negative emotions slowing it down. Arousal intensifies the influence of emotions on time perception. Approach motivation accelerates time perception, while withdrawal motivation delays it.

Summary: This study examines the effects of post-encoding emotion on second language vocabulary learning. The results show that positive emotion impairs both item memory and associative memory. However, there is no significant effect of post-encoding emotion on semantic memory. This study has theoretical and practical implications for second language vocabulary learning.

Summary: This study aimed to examine the processing and encoding of multisensory emotional experiences in memory. The results showed that negative emotions were more closely associated with activity in visual and auditory processing regions, and the amplification of negative emotion signals was related to the activity in the hippocampus and amygdala. However, for neutral stimuli, stronger representations in visuo-auditory regions were related to subsequent memory, while they were related to subsequent forgetting of positive and negative stimuli.

Summary: The regularities of the world create a complex interaction between the past and present. Current-trial perception can be automatically influenced by preceding trials, known as serial bias. In two auditory categorization experiments, we show that serial bias results from the combination of past-trial neural reactivation and the encoding of current-trial features. The meeting of past and present alters the neural representation of current-trial features and affects serial bias behavior.

Summary: This study aimed to investigate the relationship between object categorization in natural scenes and emotional engagement by manipulating both bottom-up information and top-down context. The findings suggest that semantic analysis of visual scenes, in terms of object categorization, is a necessary condition for emotional engagement at the electrocortical level.

Summary: This study examined the moderating role of effort intensity in the relationship between affect and time perception using academic-related tasks and conditions. The findings suggest that task enjoyment is essential for perceiving time passing faster, regardless of different tasks and effort levels. Additionally, the relationship between task enjoyment and perceived speed of time is influenced by perceived effort.

Summary: This study examined the role of visual and auditory cortices in the processing of multisensory information using event-related potentials. The results showed that the second audiovisual stimulus in both spatial and temporal bisection tasks elicited an early ERP response in visual and auditory regions. However, this response was more prominent in the occipital areas during the spatial task and in the temporal areas during the temporal task.

Summary: Emotion recognition abilities are crucial for social interaction. Disorders related to dopamine system disruption often show impairments in emotion recognition. However, the effects of dopamine on emotion recognition vary depending on individual baseline dopamine levels, and this aspect has not been adequately addressed in previous research.

Summary: The emerging brain-inspired computing paradigm, hyperdimensional computing (HDC), offers a lightweight learning framework for various cognitive tasks compared to traditional deep learning methods. This study proposes an architecture for processing spatio-temporal (ST) signals within the HDC framework using in-memory compute arrays, achieving significant energy efficiency, area, and throughput gains while maintaining peak classification accuracy.

Summary: Through cross-sectional and longitudinal studies on adolescents, it was found that there is not strong evidence of a relationship between risk-taking to obtain reward and depressive symptoms, and sex differences do not seem to contribute to this relationship.

Summary: Reward processing impairment in Parkinson's disease varies according to dopamine medication state and subcomponents, suggesting a potential treatment target and mechanism underlying associated neuropsychiatric syndromes. Impulse control disorder is the only neuropsychiatric syndrome with enough studies for meta-analysis, showing no significant impairment compared to non-ICD patients.

Summary: Research shows that individuals with higher trait-anxiety tend to engage in more exploration, but this has a negative impact on overall performance. Decision-making in anxious individuals is guided more towards uncertainty reduction and less towards immediate value gains.

Summary: The article discusses methods for evaluating the excitatory-inhibitory balance at 7T, comparing edited and non-edited strategies. It was found that non-edited sequences at an echo time of 80 ms provide better reproducibility than either edited sequences at the same TE, or non-edited sequences at a shorter TE of 42 ms. This is supported by numerical simulations.

Summary: This study explored the impact of long-term greenspace deprivation on how children evaluate rewards and punishments and make decisions. The findings showed that children growing up in neighborhoods with less greenspace displayed a higher acceptance of risk. However, the deprivation of local greenspace did not significantly affect other aspects of reward and punishment sensitivity.

Summary: The debate on the scope and limits of unconscious visual processing under continuous flash suppression (CFS) has resulted in divergent findings. This study aimed to investigate the hypothesis of CFS attenuation by inattention using functional magnetic resonance imaging (fMRI) and multivariate pattern analysis (MVPA). The results did not support the hypothesis, but showed higher decoding accuracies for visible stimuli compared to invisible stimuli.

Summary: Threat-related information attracts attention and disrupts ongoing behavior, especially for more anxious individuals. Our research shows that high trait anxiety increases the avoidance of objects previously associated with neutral monetary feedback and fearful faces. This avoidance is due to the increased integration of fearful faces during feedback learning in more anxious individuals. Our results also suggest that the prediction error signal uniquely accounted for by fearful faces correlates more strongly with activity in the right DLPFC in more anxious individuals.

Summary: This study explores the neurobehavioral mechanisms behind the lingering influences of outcomes and feedbacks on behavior. It suggests that the average reward rate (ARR) may regulate motivated behavior and interact with dopamine-sensitive cognitive processes. The findings have implications for understanding mood disorders and abnormal behaviors related to dopamine dysfunction.

Summary: The study found that COVID-19 social isolation has an impact on emotional and social cognitive function, with reduced contact with friends, smaller household size, and changes in communication methods leading to a decrease in positive bias in emotion recognition and attention to emotional faces. Conversely, increased contact with friends and family during social isolation was associated with greater cooperative behavior.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
