All Ss were audiometrically normal. Dichotic performances were assessed across age and condition. Pairs of words from the Peabody Picture Vocabulary Test (open-context) and common color names (closed-context) were presented simultaneously to both ears at about 70 db SPL by stereo tapes and earphones. Each pair was adjusted to +/- 3 msec for time-of-onset and +/- 4 db in level. S reported words heard. Performance was assessed for single- and for double-correct responses and for order-of-report (L-first, R-first) bias. Consistent with earlier findings, children showed R-ear-advantage in the single-correct and order-of-report measures for both stimulus sets. Double-correct scores were considerably and significantly higher for all Ss for the closed-context words. The older children (Grade 5) performed at adult levels on the double-correct measure for closed-context words, but not on any measure for the open-context words. The children's order-of-report biases were nearly identical to the normal adults'. As expected, the aphasic subgroups performed poorer than any normal subgroups, except K, and those of traumatic etiology yielded responses generally poorer than those of cerebrovascular origin. From the stabilized aphasic patient data we conclude that the R hemisphere appears to have a compensatory capacity for language acquisition subsequent to L hemisphere damage, and that dichotic testing is sensitive not only in aphasia generally, but can distinguish between certain aphasiogenic categories.</p>","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"24 4","pages":"265-78"},"PeriodicalIF":0.0,"publicationDate":"1984-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17603007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-therapy baselines were also obtained on a speech-to-noise (S-in-N) task, a test of phonemic synthesis (PS) and a new procedure with staggered dichotic digits (SDD) patterned after the SSW. The therapy for the 5 Exper. Ss consisted of 15 lessons, given 1 hr each, 2 per week, using staggered dichotic digits [termed Digit Offset Therapy (DOT)]. The \"competing\" portion of the items ranged from complete overlap to 500-msec separation.

Following DOT, the original test battery was readministered to both groups. During the therapy, significant improvement was noted for the Exper. Grp from Sessions 5 through 15 (less than .05 level) compared to the pre-therapy baseline. On the central tests, pre- and post-therapy, the Exper.

Ss were 4 normal-hearing young adults. Tone-Only (TO), Masker-Only (MO), and Tone-Masker (TM) responses were collected. The visual impression was that the TO response was not significantly different from the extracted response to the tone (T) from the TM response. This result obtained when the tone in the TM condition was presented either slightly above (+5 db) or slightly below (-5 db) perceptual threshold. Backward masking was discussed in terms of two contrasting views of the auditory system: the classical auditory nervous system alone and a parallel system combining the classical auditory and the reticular sensory systems. Speculations were made for each system regarding the type of AER expected for a stimulus submerged in backward masking. The mechanism responsible for backward masking was seen as a preperceptual device that allows discrete samples of the auditory environment to be processed. This mechanism was discussed in terms of its possible relation to forward masking and to loudness enhancement.</p>","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"24 4","pages":"279-97"},"PeriodicalIF":0.0,"publicationDate":"1984-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17603008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
