Summary: Amplitude and frequency modulations are crucial for speech intelligibility, especially in noisy environments. While young and aged animals have comparable behavioral performances, age-related deficits in discrimination abilities become more significant as differences and modulation depths decrease. This suggests additional factors affecting perception in aging beyond neurophysiological responses.

Summary: This study aims to investigate the functional relationship between P3b behavioral response and cortical neuronal oscillations of cognitive load activity in different phonological features of speech stimulus. The results showed that the control group exhibited higher amplitudes and delayed latency during placing contrast, while the patient group showed lower P3b amplitudes and earlier latency under similar conditions. The control group had higher power energy in alpha and theta activities. These findings contribute to a better understanding of the loss of attention and perception task withdrawal among individuals with hearing loss during higher order processing.

Summary: Working memory load can modulate the neural activity of different linguistic units during speech processing. Verbal and visual working memory load have similar effects on speech processing, possibly influenced by the domain-general component of the working memory system. Furthermore, working memory load asymmetrically affects lower-level auditory encoding and higher-level linguistic processing, reflecting the reallocation of attention induced by mnemonic load.

Summary: This study evaluated attention function in patients with myotonic dystrophy type 1 (DM1) using auditory event-related potential (ERP). The results showed a delayed response to novel stimuli in DM1 patients, while the response to target stimuli was similar to normal controls. Furthermore, there were significant correlations between the amplitudes of P3a and P3b with the completion rates of neuropsychological tests in DM1 patients.

Summary: This study found differences in early perceptual processing of auditory stimuli in children with ASD, while no differences were observed in tactile stimuli. However, there were no differences in response to tactile and auditory stimuli in later attentional components between ASD and TD groups. These results suggest that differences in auditory responsivity patterns in children with ASD may be related to perceptual factors.

Summary: This study aimed to investigate the neurophysiological and psychoacoustical responses after a month of daily exposure to pink noise sounds with modified frequency responses of different headphone models. The results indicated a greater area under the curve of event-related potentials (ERPs) in participants assigned to the headphone model group that negligibly modified the frequency content of pink noise, suggesting a broader cognitive process and significant neuroplasticity caused by constant auditory stimulation.

Summary: This study examines the impact of working memory load on threat extinction. The results show that under high working memory load, the late positive potential (LPP) for threatening stimuli is reduced and extinction learning is slowed down. This provides empirical evidence for the importance of limiting distraction to optimize extinction learning efficiency in exposure therapy.

Summary: While high reward expectation enhances the encoding of spatial information, the percentage of trials in which the cued location was correctly fixated decreases with increasing reward expectation. Reward expectation enhances the reconstruction of the global temporospatial sequence, but does not affect local reconstruction performance. The improvements in local representations of uncued locations and local sequences come at the cost of representation of cued locations, indicating that the reward effect on spatial working memory is modulated by the level of processing.

Summary: This study used an RNN to model changes in ERP morphology during transitions between states of consciousness. The results showed that during the transition from anesthesia to consciousness, specific peak amplitudes within certain time ranges displayed sigmoid characteristics. This method has the potential to be applied to human data, supporting the clinical use of ERPs to predict transitions in consciousness.

Summary: This study systematically investigated the detection and neural processing of auditory stimuli during a visual working memory task with varying load. The results showed that under high load, stimulus detection and P3 were decreased, while N1 amplitudes were unaffected. However, load-independent awareness effects were observed during both early (N1) and late (P3) time windows. These findings suggest that visual working memory load has a late neural effect on auditory stimuli, leading to a lower probability of awareness.

Summary: This study investigates the effects of age on neural responses to different types of modulations, such as amplitude and frequency modulations. The results show that older adults have stronger neural synchronization but weaker sustained neural activity compared to younger adults. This indicates age differences in the sensitivity of the auditory system to features present in speech and other natural sounds.

Summary: The study explored the impact of pre-stimulus alpha power and phase on subsequent visual-evoked responses using magnetoencephalography recordings and a near-threshold visual detection task. Results indicated distinct neural generators for pre-stimulus effects, with power effects mainly in occipital-temporal regions and phase effects involving prefrontal areas. It was found that only alpha power influenced the post-stimulus correlate of conscious access, while alpha phase effects did not show an impact.

Summary: According to the ideomotor theory, action can produce desired sensory outcomes, with action intentions resulting in reliable top-down predictions that modulate auditory brain responses. The extended auditory event representation system explains the effects of action intention on auditory processing and allows for studying the differences and commonalities with regularity-based predictions, guiding future research on action and perception.

Summary: Action is an important way for children to learn about the world. Recent theories suggest that action is accompanied by sensory prediction of its effects, which can be revealed by omission responses. This study investigated omission-related brain responses in children and found that although there were developmental differences, children were able to implement specific and unspecific predictions as flexibly as adults.

Summary: Listening to task-irrelevant speech can disrupt attention and performance. In this study, participants were exposed to meaningful and non-meaningful speech while performing a non-linguistic attention task. Results showed that semantic processing of the native language consumed attentional resources, resulting in reduced processing of the task sounds.

Summary: This article introduces how to conduct an amplitude difference analysis of event-related potentials (ERPs) based on temporal principal component analysis (PCA), with a focus on developmental research. It demonstrates how separate PCAs can be used to address the measurement non-invariance issue between different age groups, and provides a method to rescale the results to original units for inferential statistics. The article also discusses typical challenges and potential limitations in the analysis process.

Summary: This study compared the differences in action-effect prediction among three types of intentional actions: selecting what to do, selecting when to act, and selecting whether to perform the action or not. Results showed that regardless of the decision made, there were significant P2 differences between standard and deviant tones reflecting the formation of action-effect predictions. Furthermore, the prediction effect was not observable in non-action trials within the "whether" condition, suggesting an action-specific prediction process.

Summary: It is remarkable how human listeners can perceive periodicity in noise, which lacks obvious physical cues. Previous research suggested that listeners rely on short temporally local and idiosyncratic features to perceptually segment periodic noise sequences. The present study aimed to examine the consistency of perceptual segmentation within and between listeners. Results showed that the consistency was stronger for interleaved periodic sequences, likely due to reduced temporal jitter. Additionally, the finding that certain noise sequences were segmented consistently across listeners challenges the assumption that the features are necessarily idiosyncratic.

Summary: Perceptual learning is a powerful mechanism for enhancing perceptual abilities and forming memory representations of unfamiliar sounds. The current study examined how the learning of random acoustic patterns is influenced by pattern repetition regularity and listener attention. The findings demonstrate that memory-related effects are observed even during the first occurrence of patterns, especially when listeners pay attention to the sounds.

Summary: The study found that the sudden siren of an ambulance can interfere with people's attention and performance. The experiment showed that when the target and the distracting sound occurred on the same side, individuals responded faster, indicating a spatial shift of attention. The results of the brainwave data also supported this finding, suggesting that spatial attention bias influences the impact of distracting sounds.

Summary: This study aimed to investigate the pupil's response to unexpected stimulus omissions in order to better understand surprise and orienting of attention resulting from prediction violation. The results revealed that omission responses were observed in both auditory and somatosensory modalities in the 88%-condition compared to motor-control. The discussion suggests that these findings demonstrate predictive models in brain processing and point to the involvement of subcortical structures in the omission response.
