Aivoaaltoihin perustuva tutkimus tarjoaa arvokasta tietoa kielenk\u00e4sittelyn ja aivojen rytmisen toiminnan v\u00e4lisest\u00e4 yhteydest\u00e4. Tutkimuksen p\u00e4\u00e4tavoitteena on selvitt\u00e4\u00e4, miten EEG-aivokuvantamisessa (elektroenkefalografia) havaitut taajuuskomponentit eroavat \u00e4idinkielen ja vieraan kielen k\u00e4sittelyss\u00e4 sek\u00e4 millaisia muutoksia ty\u00f6muistin kuormitus (kolmen vs. viiden sanan lauseet) aiheuttaa aivoaaltojen aktiivisuudessa.\nTutkimukseen osallistui 11 suomenkielist\u00e4 aikuista, joilla oli vain v\u00e4h\u00e4ist\u00e4 aikaisempaa altistumista englannin kielelle. EEG-aineisto ker\u00e4ttiin Interlearn Pieni karhu-pilottitutkimuksesta ja analysoitiin tilastollisella sis\u00e4ll\u00f6nanalyysilla. Tulokset osoittavat selvi\u00e4 eroja aivotoiminnassa, kun osallistujat kuuntelivat \u00e4idinkielt\u00e4\u00e4n verrattuna vieraaseen kieleen. \u00c4idinkielt\u00e4 kuunneltaessa beeta- ja gamma-aaltojen aktiivisuus oli voimakkaampaa, samoin kuin theta- ja alfa-aaltojen. N\u00e4m\u00e4 l\u00f6yd\u00f6kset viittaavat lis\u00e4\u00e4ntyneeseen kognitiiviseen kuormitukseen ja tarkkaavuuden kasvuun \u00e4idinkielt\u00e4 kohtaan, mik\u00e4 on yhdenmukaista aikaisempien tutkimusten l\u00f6yd\u00f6sten kanssa. Auditiivisen ty\u00f6muistin osalta havaittiin, ett\u00e4 theta- ja alfa-aaltojen aktiivisuudet heikkeniv\u00e4t muistiteht\u00e4v\u00e4n ollessa yksinkertaisempi (lyhyemm\u00e4t lauseet), mik\u00e4 on my\u00f6s yhdenmukaista aiempien tutkimusten kanssa. Sen sijaan beeta- ja gamma-aallot kuitenkin voimistuvat, mik\u00e4 saattaa johtua teht\u00e4v\u00e4n rakenteesta, lauseiden monimutkaisuudesta tai yksil\u00f6llisist\u00e4 kognitiivisista strategioista.\nTutkimustulokset syvent\u00e4v\u00e4t ymm\u00e4rryst\u00e4 kielen prosessoinnin ja aivojen rytmisen toiminnan v\u00e4lisest\u00e4 yhteydest\u00e4. Tulokset tarjoavat uutta tietoa siit\u00e4, miten \u00e4idinkielen ja vieraan kielen prosessointi sek\u00e4 ty\u00f6muistin kuormitus heijastuvat aivotoiminnassa. T\u00e4m\u00e4 voi olla merkityksellist\u00e4 kielellisten vaikeuksien ymm\u00e4rt\u00e4misess\u00e4 ja hoitamisessa. Tulokset voivat osaltaan ohjata jatkotutkimusta esimerkiksi kielten oppimisen ja oppimisvaikeuksien tunnistamisen aloilla. Tutkimuksen perusteella ilmenee tarve jatkotutkimuksille, joissa tulisi kehitt\u00e4\u00e4 koeasetelmia erityisesti aikuisille osallistujille, lis\u00e4t\u00e4 tutkimuksissa kesken\u00e4\u00e4n verrattavien kielten lukum\u00e4\u00e4r\u00e4\u00e4, sek\u00e4 soveltaa tilastollisia malleja. Lis\u00e4ksi pitkitt\u00e4istutkimuksille on alalla tarvetta, jotta voidaan paremmin ymm\u00e4rt\u00e4\u00e4, miten aivojen oskillaatiot tukevat puheen k\u00e4sittely\u00e4 ja auditiivista ty\u00f6muistia.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-06-13T06:09:03Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-06-13T06:09:03Z (GMT).
