Japanese Infants

The developmental change in auditory preferences for speech stimuli was investigated for Japanese infants aged 4–14 months old. We conducted three experiments using two speech pairs in the head-turn preference procedure. Infant-directed (ID) speech and adult-directed (AD) speech stimuli were used in a longitudinal study (Experiment 1) and a cross-sectional study (Experiment 2). Native (Japanese) and non-native (English) speech stimuli were used in a cross-sectional study (Experiment 3). In all experiments, infants demonstrated a developmental change in their listening preference. For the ID/AD speech pair used in Experiments 1 and 2, infants show a U-shaped developmental shift with three developmental stages: Stage 1, in which very young infants tend to prefer ID speech over AD speech; Stage 2, in which the preference for ID speech decreases temporarily; and Stage 3, in which older infants again show a consistent preference for ID speech. For the native/non-native speech pair, there is a tendency for an increased preference for native speech over non-native speech, although infants did not demonstrate a U-shaped pattern. The difference in developmental pattern between the two types of speech pairs was discussed.

Auditory Research

Functional Magnetic Resonance Imaging (fMRI) holds exciting potential as a research and clinical tool for exploring the human auditory system. This noninvasive technique allows the measurement of discrete changes in cerebral cortical blood flow in response to sensory stimuli, allowing determination of precise neuroanatomical locations of the underlying brain parenchymal activity. Application of fMRI in auditory research, however, has been limited. One problem is that fMRI utilizing echo-planar imaging technology (EPI) generates intense noise that could potentially affect the results of auditory experiments. Also, issues relating to the reliability of fMRI for listeners with normal hearing need to be resolved before this technique can be used to study listeners with hearing loss. This preliminary study examines the feasibility of using fMRI in auditory research by performing a simple set of experiments to test the reliability of scanning parameters that use a high resolution and high signal-to-noise ratio unlike that presently reported in the literature. We used consonant-vowel (CV) speech stimuli to investigate whether or not we could observe reproducible and consistent changes in cortical blood flow in listeners during a single scanning session, across more than one scanning session, and in more than one listener. In addition, we wanted to determine if there were differences between CV speech and nonspeech complex stimuli across listeners. Our study shows reproducibility within and across listeners for CV speech stimuli. Results were reproducible for CV speech stimuli within fMRI scanning sessions for 5 out of 9 listeners and were reproducible for 6 out of 8 listeners across fMRI scanning sessions. Results of nonspeech complex stimuli across listeners showed activity in 4 out of 9 individuals tested.

Cortical Auditory Evoked Potentials

Introduction: Cortical auditory evoked potentials can provide objective information about the highest level of the auditory system. Aim: The purpose of the authors was to introduce a new tool, the “HEARLab” which can be routinely used in clinical practice for the measurement of the cortical auditory evoked potentials. In addition, they wanted to establish standards of the analyzed parameters in subjects with normal hearing. Method: 25 adults with normal hearing were tested with speech stimuli, and frequency specific examinations were performed utilizing pure tone stimuli. Results: The findings regarding the latency and amplitude analyses of the evoked potentials confirm previously published results of this novel method. Conclusions: The HEARLAb can be a great help when performance of the conventional audiological examinations is complicated. The examination can be performed in uncooperative subjects even in the presence of hearing aids. The test is frequency specific and does not require anesthesia. Orv.
