Among the earliest and most frequent words that infants hear are their names. Yet little is known about when infants begin to recognize their own names. Using a modified version of the head-turn preference procedure, we tested whether 4.5-month-olds preferred to listen to their own names over foils that were either matched or mismatched for stress pattern. Our findings provide the first evidence that even these young infants recognize the sound patterns of their own names. Infants demonstrated significant preferences for their own names compared with foils that shared the same stress patterns, as well as foils with opposite patterns. The results indicate when infants begin to recognize sound patterns of items frequently uttered in the infants' environments.

We appreciate Reierson's thoughtful commentary on our 2019 paper, which described our experiences, ethical process, judgment calls, and lessons from a 2016-2017 data-sharing pilot between Crisis Text Line and academic researchers. The commentary raises important questions about the ethical conduct of health research in the digital age, particularly regarding informed consent, potential conflicts of interest, and the protection of vulnerable populations. Our article focused specifically on the noncommercial use of Crisis Text Line data for research purposes, so we restrict our reply to points relevant to such usage.

Animals employ various strategies to minimize the overlap of their vocalizations with other sounds, thereby enhancing the effectiveness of their communication. However, little attention has been given to experimentally examining how the structure of the acoustic signal changes in response to various kinds of disturbances in the soundscape. In this study, I experimentally investigated whether male thrush nightingales (Luscinia luscinia) adjust their singing rate, song frequency, and song type in response to different types of artificial sounds.

In everyday hearing, listeners face the challenge of understanding behaviorally relevant foreground stimuli (speech, vocalizations) in complex backgrounds (environmental, mechanical noise). Prior studies have shown that high-order areas of human auditory cortex (AC) pre-attentively form an enhanced representation of foreground stimuli in the presence of background noise. This enhancement requires identifying and grouping the features that comprise the background so they can be removed from the foreground representation.

With the increasing survival rates of premature infants and their associated respiratory problems, noninvasive ventilation has gained popularity in neonatal intensive care units. On the other hand, this equipment can be stressful for infants. Objective: This study aimed to compare the effects of white noise and sound reduction on the behavioral responses of premature infants under noninvasive ventilation.

Speech comprehension involves the dynamic interplay of multiple cognitive processes, from basic sound perception, to linguistic encoding, and finally to complex semantic-conceptual interpretations. How the brain handles the diverse streams of information processing remains poorly understood. Applying Hidden Markov Modeling to fMRI data obtained during spoken narrative comprehension, we reveal that the whole brain networks predominantly oscillate within a tripartite latent state space.
