Kuvat otettiin Karolinska Directed Emotional Faces (KDEF) kuvapankista. Aina kun kuvia oli n\u00e4ytetty satunnainen m\u00e4\u00e4r\u00e4, osallistujia pyydettiin tunnistamaan kasvonilmeiden tunnetila painamalla tunnetilaa vastaavaa nappia ohjaimesta. Piirreahdistuneisuutta mitattiin Karolinska Scales of Personality (KSP) inventaariolla. Takaraivo- ja p\u00e4\u00e4lakilohkot valittiin tarkempaan tarkasteluun kolmessa eri aikaikkunassa. Aktivaatiohuiput kyseisiss\u00e4 aikaikkunoissa voisivat vastata her\u00e4tepotentiaaleja M100, M170, EPN, VPP, M220 ja M300 tai LPP, joita on k\u00e4ytetty aiemmissa tutkimuksissa. Tilastollisissa analyyseissa vain M220-vaste oli voimakkaampi pelokkaisiin ilmeisiin verrattuna surullisiin ilmeisiin. Lis\u00e4ksi, M220-vaste oli voimakkaampi pelokkaisiin ilmeisiin verrattuna neutraaleihin sek\u00e4 vihaisiin ilmeisiin, mutta vain oikeassa aivopuoliskossa. N\u00e4m\u00e4 tulokset olivat kuitenkin ainoastaan suuntaa antavia. Muita eroja neutraalien sek\u00e4 tunnepitoisten kasvonilmeiden v\u00e4lill\u00e4 ei l\u00f6ytynyt. Piirreahdistuneisuus korreloi positiivisesti tunnepitoisten, neutraalien tai kaikkien kasvonilmeiden aiheuttamien M170-, VPP- ja M300- tai LPP-vasteiden voimakkuuden kanssa. Tutkimuksemme viittaa siihen, ett\u00e4 visuaalisilta alueilta mitatut her\u00e4tevasteet eiv\u00e4t ole sensitiivisi\u00e4 eri negatiivisten tunnetilojen kasvonilmeille, ja ett\u00e4 piirreahdistuneisuus on yhteydess\u00e4 tehokkaampaan varhaiseen uhan prosessointiin, tehokkaampaan kasvojen rakenteelliseen prosessointiin sek\u00e4 tehokkaampaan kasvojen tietoiseen prosessointiin.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "The aim of this study was first to investigate whether different negative and neutral facial expressions are processed differently and second to investigate whether trait anxiety affects this processing. 14 men, aged 20\u201354 years, viewed pictures of different negative and neutral facial expressions during a measurement of brain electric activation with MEG. The pictures were taken from the Karolinska Directed Emotional Faces (KDEF) set. After a random number of pictures, the participants were asked to identify the emotion the face was expressing by pressing a corresponding button. Trait anxiety was measured with Karolinska Scales of Personality (KSP) inventory. Occipital and parietal areas on three time-windows were chosen for further analysis. Peaks of activation were found in time-windows roughly corresponding to the M100, M170, EPN, VPP, M220 and the M300 or the LPP that have been used in previous studies. In the statistical analysis, only the M220 response was stronger to afraid faces compared to sad faces. In addition, the M220 response was stronger to afraid faces compared to neutral and angry faces but only on the right hemisphere. However, these effects were only approaching significance. No other differences between emotional and neutral expressions were found. Trait anxiety correlated positively with the strength of the M170, VPP and the M300 or the LPP responses to either emotional or neutral facial expressions, or both. Our study thus suggests that the evoked responses measured from the visual areas were not sensitive to different negative emotional expressions, and trait anxiety is associated with an early threat processing bias, enhanced structural encoding of the face and enhanced conscious processing of the face.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-12-19T05:38:14Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-12-19T05:38:15Z (GMT).
