Electrical activity was recorded from the scalp while the children listened for semantically and\/or syntactically\n anomalous words from either the right side or the left side while competing segments of the fairy tale were simultaneously presented from the opposite side. Latencies and amplitudes were averaged for each target condition within the group with dichotic left-ear deficits (LED) and the group\n with normal dichotic listening performance (WNL). Individual global field power waveforms and topographic brain maps were generated for the average response in each of the two listening conditions, target right and target left. Cross-correlations were performed on the grand averaged global\n field power waveforms to measure the degree of synchrony between target right and target left responses in both groups. Integration functions were performed to compare the accumulated sum of voltages during target (right and left) and control (right and left) conditions. WNL children produced\n typical ERP responses to the target words in both target right and target left conditions. Responses from LED children were at delayed latencies in the target left condition and were at reduced amplitudes in both target conditions. Topographic brain maps revealed more lateralized scalp distributions\n and greater activation of frontal regions in LED children in the target left condition. Cross-correlational and integration function results demonstrated interaural asymmetries in responses from the LED children. Overall results suggest that slowed neural conduction times, poor interhemispheric\n transfer of neural activity, and a failure to suppress competing information arriving at the right ear may be involved in poor left-sided processing in children with behavioral left-ear dichotic deficits. Ni\u00f1os con y sin deficiencias dic\u00f3ticas conductuales del o\u00eddo izquierdo\n participaron en un estudio de potenciales relacionados con el evento, con presentaciones cuasi-dic\u00f3ticas de segmentos familiares de cuentos de hadas. La actividad el\u00e9ctrica se registr\u00f3 en el cr\u00e1neo mientras los ni\u00f1os escuchaban buscando palabras an\u00f3malas,\n sem\u00e1ntica o sint\u00e1cticamente, tanto del lado derecho como del lado izquierdo, mientras que se les presentaban simult\u00e1neamente segmentos competitivos del cuento de hadas en el lado opuesto. Se promediaron las latencias y las amplitudes para cada condici\u00f3n dentro del\n grupo con deficiencias dic\u00f3ticas en el o\u00eddo izquierdo (LED) y del grupo con desempe\u00f1o auditivo dic\u00f3tico normal (WNL). Se generaron ondas de poder de campo global individuales y mapas topogr\u00e1ficos cerebrales, para la respuesta promedio en cada una de las dos\n condiciones auditivas: meta en el lado derecho y meta en el izquierdo. Se realizaron correlaciones cruzadas con el gran promedio de las ondas de poder de campo global, para medir el grado de sincron\u00eda entre las respuestas con meta en el lado derecho o meta en el izquierdo, en ambos\n grupos. Se realizaron funciones de integraci\u00f3n para comparar la suma acumulada de voltajes durante las condiciones meta (derecha e izquierda) y control (derecha e izquierda). Los ni\u00f1os WNL produjeron respuestas ERP t\u00edpicas ante las palabras meta, tanto en condiciones de\n meta derecha o meta izquierda. Las respuestas de los ni\u00f1os LED mostraron latencias retardadas en las condiciones de meta izquierda y mostraron amplitudes reducidas en ambas condiciones meta. Los mapas topogr\u00e1ficos revelaron distribuciones craneales m\u00e1s lateralizadas y\n mayor activaci\u00f3n de las regionales frontales en los ni\u00f1os LED, en la condici\u00f3n meta izquierda. Las funciones de integraci\u00f3n y de correlaci\u00f3n cruzada demostraron asimetr\u00ed as interaurales en las respuestas del los ni\u00f1os LED. Los resultados globales\n sugieren que el hallazgo de tiempos de conducci\u00f3n neuronal lentos, una pobre transferencia de actividad neuronal inter-hemisf\u00e9rica y una falla para suprimir informaci\u00f3n competitiva que arriba al o\u00eddo derecho, puede estar involucrado en un pobre procesamiento del\n lado izquierdo, en ni\u00f1os con deficiencias conductuales dic\u00f3ticas del o\u00eddo izquierdo.<\/jats:p>","DOI":"10.3766\/jaaa.15.7.6","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"518-534","source":"Crossref","is-referenced-by-count":14,"title":["ERP Evidence of a Dichotic Left-Ear Deficit in Some Dyslexic Children"],"prefix":"10.3766","volume":"15","author":[{"given":"Deborah","family":"Moncrieff","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Jerger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilse","family":"Wambacq","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralf","family":"Greenwald","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey","family":"Black","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2004\/00000015\/00000007\/art00006","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:09:51Z","timestamp":1738796991000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.15.7.6"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,7,1]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2004,7,1]]}},"alternative-id":["1050-0545(20040701)15:7L.518;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.15.7.6","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2004,7,1]]}}}
