The auditory gaze cueing effect (auditory-GCE) is a faster response to auditory targets at an eye-gaze cue location than at a non-cue location. Previous research has found that auditory-GCE can be influenced by the integration of both gaze direction and emotion conveyed through facial expressions. However, it is unclear whether the emotional information of auditory targets can be cross-modally integrated with gaze direction to affec auditory-GCE. Here, we set neutral faces with different gaze directions as cues and three emotional sounds (fearful, happy, and neutral) as targets to investigate how the emotion of sound target modulates the auditory-GCE. Moreover, we conducted a controlled experiment using arrow cues. The results show that the emotional content of sound targets influences the auditory-GCE but only for those induced by facial cues. Specifically, fearful sounds elicit a significantly larger auditory-GCE compared to happy and neutral sounds, indicating that the emotional content of auditory targets plays a modulating role in the auditory-GCE. Furthermore, this modulation appears to occur only at a higher level of social meaning, involving the integration of emotional information from a sound with social gaze direction, rather than at a lower level, which involves the integration of direction and auditory emotion.

Objective: We aimed to investigate the correlation between prevalent risk factors for high-risk neonates in neonatal intensive care unit and their hearing loss, and to examine the audiological features and genetic profiles associated with different deafness mutations in our tertiary referral center. This research seeks to deepen our understanding of the etiology behind congenital hearing loss.
Methods: We conducted initial hearing screenings, including automated auditory brainstem response, distortion product otoacoustic emission, and acoustic immittance on 443 high-risk neonates within 7 days after birth and 42 days (if necessary) after birth.

Background: Fragile X syndrome (FXS) is a leading known genetic cause of intellectual disability and autism spectrum disorders (ASD)-associated behaviors. A consistent and debilitating phenotype of FXS is auditory hypersensitivity that may lead to delayed language and high anxiety. Consistent with findings in FXS human studies, the mouse model of FXS, the Fmr1 knock out (KO) mouse, shows auditory hypersensitivity and temporal processing deficits.

Article Synopsis
- Neuropsychiatric symptoms (NPS) in Alzheimer's disease significantly impact patient function and caregiving needs, with worse NPS scores linked to increased care requirements.
- Data from participants diagnosed with Mild Cognitive Impairment or Alzheimer's were analyzed over an average of 4 years to assess the effects of various NPS on functional decline using several assessment tools.
- Results indicated that common symptoms like apathy, depressed mood, and anxiety are prevalent, with apathy being the most persistent symptom across participants, suggesting potential targets for improving patient outcomes.

Profile-analysis experiments measure the ability to discriminate complex sounds based on patterns, or profiles, in their amplitude spectra. Studies of profile analysis have focused on normal-hearing listeners and target frequencies near 1 kHz. To provide more insight into underlying mechanisms, we studied profile analysis over a large target frequency range (0.
