Tutkit-tavina oli 25 tyypillisesti kehittynytt\u00e4 lasta: 13 tytt\u00f6\u00e4 ja 12 poikaa. 5-vuotiaita oli yhdeks\u00e4n, 6-vuotiaita oli 16. Tutkittavat oli rekrytoitu Jyv\u00e4skyl\u00e4st\u00e4 ja sen l\u00e4hialueilta V\u00e4est\u00f6rekisterikeskukselta saatujen tietojen pohjalta. Tutkimuksessa tehtiin sek\u00e4 EEG-mittaus ett\u00e4 k\u00e4ytt\u00e4ytymistason testej\u00e4. EEG-mittauksessa k\u00e4ytettiin ns. oddball-asetelmaa, jossa taajuudeltaan 500 Hz:n sini\u00e4\u00e4nen seassa soitettiin poikkeavana \u00e4rsykkeen\u00e4 425 Hz:n sini\u00e4\u00e4nt\u00e4. K\u00e4ytt\u00e4ytymistason testej\u00e4 oli kaksi: Ensimm\u00e4isess\u00e4 tutkittavien piti kuunnella kolmen sini\u00e4\u00e4nen joukosta, mik\u00e4 \u00e4\u00e4nist\u00e4 oli taajuudeltaan korkeampi kuin kaksi muuta. Toisessa testiss\u00e4 kuunneltavina oli synteettisesti muodostettuja y- ja i-vokaaleja, ja tutkittavan piti erottaa kolmen vokaalin joukosta yksi poikkeava.\r\nTutkimuksen perusteella 5\u20146-vuotiaiden lasten kuulovasterakenne muodostuu P1\u2014N2-aalloista, joista P1:n j\u00e4nnitehuippu osuu noin 100\u2014115 ms ja N2:n noin 200\u2014225 ms \u00e4rsykkeest\u00e4. Lis\u00e4ksi poikkeavan \u00e4\u00e4nen kuulovasteessa on n\u00e4kyviss\u00e4 ns. poikkeavuusnegatiivisuus- eli MMN-aalto (mismatch negativity) noin 230\u2014250 ms \u00e4rsykkeest\u00e4. L\u00e4hdeanalyysin perusteella P1- ja N2-aaltojen syntypaikkaa kuvasi tangentiaalisesti suuntautunut dipolipari, joka sijoittui molempiin aivopuoliskoihin ylemm\u00e4n temporaalipoimun sis\u00e4osiin. N2-aallon taustalta l\u00f6ytyi my\u00f6s toinen dipo-lipari, joka oli orientaatioltaan radiaalinen ja sijoittui my\u00f6s ylemm\u00e4lle temporaalipoimulle, mutta tangentiaalista lateraalisemmaksi. MMN-aalto syntyi yhdest\u00e4, tangentiaalisesti orientoituneesta di-poliparista, joka sijoittui ylemm\u00e4n temporaalipoimun sis\u00e4osiin. \r\nKuulovasteissa ei ollut eroa 5- ja 6-vuotiaiden v\u00e4lill\u00e4, mutta MMN-aallossa oli suurta yksil\u00f6llist\u00e4 vaihtelua. K\u00e4ytt\u00e4ytymistason testien perusteella voitiin n\u00e4hd\u00e4, ett\u00e4 tietoinen taajuuden erottelukyky kehittyy 5 ja 6 ik\u00e4vuoden v\u00e4lill\u00e4. MMN-aallon ja tietoisen taajuuden erottelukyvyn v\u00e4lille ei l\u00f6ydetty mit\u00e4\u00e4n yhteytt\u00e4. Tutkimuksen tulokset antavat aiheen olettaa, ett\u00e4 sini\u00e4\u00e4niin liittyv\u00e4n kuulotiedon k\u00e4sittelyn kehitys on 5\u20146-vuotiailla viel\u00e4 keskener\u00e4inen.", "language": "", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Terttu Kananen (tesiteka) on 2011-10-04 14:24:39.783022.
