N\u00e4m\u00e4 negatiiviset tiedonk\u00e4sittelyn v\u00e4\u00e4ristym\u00e4t voivat vaikuttaa aivojen automaattiseen tiedonk\u00e4sittelyyn, kuten kasvonilmeiden prosessointiin. Tutkimusta aiheesta on v\u00e4h\u00e4n, ja erityisesti ik\u00e4\u00e4ntyneill\u00e4 masentuneilla aihetta ei ole aikaisemmin tutkittu. T\u00e4ss\u00e4 tutkimuksessa esitimme 18 masentuneelle ja 16 ei-masentuneelle 50-83-vuotiaalle koehenkil\u00f6lle kasvonilmekuvia kuudesta perustunteesta (ilo, suru, viha, inho, pelko, yll\u00e4tys) sek\u00e4 neutraalista kasvonilmeest\u00e4, ja mittasimme elektroenkefalografialla (EEG) aivojen s\u00e4hk\u00f6iset j\u00e4nnitevasteet kasvonilmekuviin. Halusimme tutkia ei-tarkkailtujen tunteellisten kasvonilmeiden automaattista prosessointia, joten koehenkil\u00f6t suuntasivat tarkkaavuutensa \u00e4\u00e4nikirjaan samalla kun he katselivat kasvonilmekuvia. Tarkoituksenamme oli selvitt\u00e4\u00e4, miten ei-tarkkaillut tunteelliset kasvonilmeet vaikuttavat N170-vasteeseen, joka on aikaisemmassa tutkimuksessa yhdistetty kasvonilmeiden prosessointiin. Odotimme, ett\u00e4 tunteelliset kasvonilmeet aiheuttavat suuremman N170-vasteen kuin neutraali kasvonilme. Lis\u00e4ksi tutkimme, vaikuttavatko tiedonk\u00e4sittelyn v\u00e4\u00e4ristym\u00e4t masentuneiden N170-vasteisiin. Odotimme suurempia N170-vasteita surullisiin kasvonilmeisiin ja pienempi\u00e4 N170-vasteita iloisiin kasvonilmeisiin masentuneilla ei-masentuneisiin verrattuna. Havaitsimme ett\u00e4 perustunteita esitt\u00e4v\u00e4t kasvonilmekuvat muokkasivat N170-vastetta: kasvonilmeist\u00e4 viha, suru, inho, pelko ja yll\u00e4tys her\u00e4ttiv\u00e4t suuremman N170-vasteen kuin neutraali kasvonilme. Yll\u00e4ttynyt ja pelokas kasvonilme her\u00e4ttiv\u00e4t suurimmat N170-vasteet, kun taas neutraaliin ja iloiseen kasvonilmeeseen N170-vasteet olivat pienimm\u00e4t. T\u00e4m\u00e4 voi johtua siit\u00e4, ett\u00e4 yll\u00e4ttyneess\u00e4 ja pelokkaassa kasvonilmeess\u00e4 on selke\u00e4sti erottuvia piirteit\u00e4, kuten kohonneet kulmakarvat, joiden prosessointi n\u00e4kyy suurempina N170-vasteina. T\u00e4ss\u00e4 tutkimuksessa tiedonk\u00e4sittelyn v\u00e4\u00e4ristymien ei havaittu vaikuttavan N170-vasteeseen: eroa masentuneiden ja ei-masentuneiden ryhmien v\u00e4lill\u00e4 ei ollut. Tuloksemme viittaavat siihen, ett\u00e4 masennukseen liittyv\u00e4 tiedonk\u00e4sittelyn v\u00e4\u00e4ristym\u00e4 ei ik\u00e4\u00e4ntyneill\u00e4 vaikuta kasvonilmeiden automaattiseen prosessointiin, kun tarkkaavuus ei ole kiinnittynyt kasvonilmeisiin.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Janne Rajaniemi (jajuraja) on 2017-06-12 12:36:18.091996.
