Ear and contralateral masker effects on auditory temporal gap detection thresholds

Gaps-in-noise (GIN©) test results in children with and without reading disabilities and phonological processing deficits

“…and the percent of correct identifi cation) were similar for both ears. These results are consistent with fi ndings reported in the literature for GIN test performance in both children and adults (Musiek et al, 2005;Samelli & Schochat, 2008;Shinn et al, 2009;Amaral & Colella-Santos, 2010), as well as with several other studies that employed other GD paradigms (Efron et al, 1985;Baker et al, 2008;Carmichael et al, 2008). Since there were no differences in performances between ears in any of the studies reviewed, including the present investigation, the possibility exists that accurate diagnosis of a temporal resolution defi cit could be made if testing with the GIN test were done in the soundfi eld, diotically under headphones, or monaurally in only one ear.…”

Performance at different stimulus intensities with the within- and across-channel adaptive tests of temporal resolution

“…Gap detection could entail an attentional shift from one channel to the other that requires more time than is necessary in the WC condition (Phillips & Hall, 2000). The AC gap detection thresholds obtained in the present study are similar to those obtained with the ATTR by Lister et al (2011), and also to those reported by Carmichael et al (2008) (approximately 46 -49 ms) with different software. Smaller AC threshold values have also been reported; e.g.…”

“…The WC thresholds obtained in the present study and in the Lister et al (2011) study are slightly smaller than those reported in other previous within-channel gap detection studies (Formby et al, 1993;Phillips et al, 1997), but differences in software and equipment used in those studies could have produced differences in stimulus characteristics that affected performance. In a recent study (Carmichael et al, 2008), within-channel thresholds were smaller (i.e. approximately 2.3 ms), but participant experience probably improved performance.…”

“…approximately 2.3 ms), but participant experience probably improved performance. In that study, two practice thresholds were obtained fi rst, and the reported threshold value was based on a mean of three subsequent thresholds, after participants had acquired considerable experience with the task (Carmichael et al, 2008).…”

Enabling the effective application of spatial auditory displays in modern flight decks

“…More recent studies challenge the temporal reasoning for left hemisphere dominance when tested with temporal gap experiments (Carmichael, Hall, & Phillips, 2008), and even…”
