“…An important question is whether temporal integration windows reflect a fixed property of the cortical hierarchy or whether they are shaped by attention and behavioral demands 73 . In our study, we did not give subjects a formal task because our goal was to measure integration windows during natural listening without any particular goal or attentional focus.…”

To derive meaning from sound, the brain must integrate information across many timescales. What computations underlie multiscale integration in human auditory cortex? Evidence suggests that auditory cortex analyzes sound using both generic acoustic representations (e.g. spectrotemporal modulation) and category-specific computations, but the timescales these putatively distinct computations integrate over remain unclear. To answer this question, we developed a general method to estimate sensory integration windows – the time window when stimuli alter the neural response – and applied our method to intracranial recordings from neurosurgical patients. We show that human auditory cortex integrates hierarchically across diverse timescales spanning ~50 to 400 milliseconds. Moreover, we find that neural populations with short and long integration windows exhibit distinct functional properties: short-integration electrodes (<200 milliseconds) show prominent spectrotemporal modulation selectivity, while long-integration electrodes (>200 milliseconds) show prominent category selectivity. These findings reveal how multiscale integration organizes auditory computation in the human brain.

“…As stimuli, 0 to 3 silenced gaps are embedded within 6-second white noise. There are ten different gap durations (2,3,4,5,6,8,10,12,15, and 20 ms), and the duration or location of the gaps within the noise is pseudorandomized. As each gap appears six times in each track, a total of 60 gaps were presented.…”

“…The gap detection threshold is known to depend on a variety of stimulus characteristics such as stimulus level, stimulus bandwidth, modulation features, spectral and temporal complexity, and uncertainty [1]. Several evidences suggest that gap detection performance is related to cognitive demand or attentional resources [4][5]. For example, Leung, et al [4] measured auditory event-related potentials during active and passive listening and found that gap detection performance was associated with attentional processing, possibly related to divided attention.…”

Günel, et al [5] suggested that the poorer performance of gap detection could be explained, in part, by associations with sustained attention, or cognitive ability, as speech input should be sustained in the memory for a sufficient duration.…”

Background and Objectives: The Gaps-In-Noise (GIN) test is a clinically effective measure of the integrity of the central auditory nervous system. The GIN procedure can be applied to a pediatric population above 7 years of age. The present study conducted the GIN test to compare the abilities of auditory temporal resolution among typically developing children, children with speech sound disorder (SSD), and children with cognitive difficulty (CD).Subjects and Methods: Children aged 8 to 11 years-(total n=30) participated in this study. There were 10 children in each of the following three groups: typically developing children, children with SSD, and children with CD. The Urimal Test of Articulation and Phonology was conducted as a clinical assessment of the children’s articulation and phonology. The Korean version of the Wechsler Intelligence Scale for Children-III (K-WISC-III) was administered as a screening test for general cognitive function. According to the procedure of Musiek, the pre-recorded stimuli of the GIN test were presented at 50 dB SL. The results were scored by the approximated threshold and the overall percent correct score (%).Results: All the typically developing children had normal auditory temporal resolution based on the clinical cutoff criteria of the GIN test. The children with SSD or CD had significantly reduced gap detection performance compared to age-matched typically developing children. The children’s intelligence score measured by the K-WISC-III test explained 37% of the variance in the percent-correct score.Conclusions: Children with SSD or CD exhibited poorer ability to resolve rapid temporal acoustic cues over time compared to the age-matched typically developing children. The ability to detect a brief temporal gap embedded in a stimulus may be related to the general cognitive ability or phonological processing.

Purpose: Previous studies have demonstrated that people with tinnitus show attention dysfunctions. In this study, we investigated the influence of tinnitus on attention orienting, especially whether the ability of attention orienting could be modulated by the degree of tinnitus. Method: Fifty-nine and 54 unilateral tinnitus participants were included in Experiment 1 and Experiment 2, respectively. All participants reported subjective tinnitus for at least 3 months and were divided into a mild tinnitus group (Tinnitus Handicap Inventory [THI] < 37) or a moderate to severe tinnitus group (THI ≥ 37) according to the THI score. An auditory exogenous attention task and an auditory endogenous attention task were adopted. In the exogenous task, a target sound following a cue sound was presented on either the left or right side. Participants were required to discriminate whether the target was pure tone or white noise. In the endogenous task, participants were required to pay attention to the stimuli on one side and judge the pitch of a target sound. Mixed-design analyses of variance were conducted for the mean reaction times and accuracy across the experimental conditions. Results: Our results showed that in the endogenous attention task, compared with the mild tinnitus group, moderate to severe tinnitus participants had better performance for stimuli presented on the tinnitus side but not on the nontinnitus side. In contrast, in the exogenous attention task, no differences were found between mild and moderate to severe tinnitus groups. Conclusion: The results suggest that the degree of tinnitus influences the performance of auditory endogenous attention but not auditory exogenous attention orienting.
