Lis\u00e4ksi N170, joka on kasvoille sensitiivinen her\u00e4tevaste, tyypillisesti ilmenee masentuneilla henkil\u00f6ill\u00e4 amplitudiltaan suurempana surullisiin kasvoihin, kuin terveill\u00e4 henkil\u00f6ill\u00e4. T\u00e4ss\u00e4 tutkimuksessa tarkastelimme, kuinka kokeellisesti tuotettu surullinen mieliala vaikuttaa kasvojen ilmeiden havaitsemiseen sek\u00e4 N170-vasteeseen terveill\u00e4 koehenkil\u00f6ill\u00e4. Koehenkil\u00f6t osallistuivat kahteen erilliseen mittausp\u00e4iv\u00e4\u00e4n, joissa heille aiheutettiin surullinen ja neutraali mieliala. Kasvojen ilmeiden tunnistamisteht\u00e4v\u00e4ss\u00e4 koehenkil\u00f6ille esitettiin neutraaleja ja surullisia kasvoja subliminaalisesti ja supraliminaalisesti. Koehenkil\u00f6t oli ohjeistettu vastaamaan, onko esitetty kasvo ilmeelt\u00e4\u00e4n surullinen vai neutraali. Tulokset osoittivat, ett\u00e4 kasvojen havaitsemisen tarkkuus oli parempi, kun mieliala oli yhdenmukainen kuvien kasvojen ilmeiden (surullinen tai neutraali) kanssa, mutta ainoastaan subliminaalisesti esitettyjen kasvojen osalta. Verrattuna neutraaliin mielialaan, surullisen mielialan aikana neutraalit kasvot arvioitiin useimmin surullisiksi kasvoiksi. Tulokset N170-vasteen osalta supraliminaalisessa tilanteessa osoittivat, ett\u00e4 neutraalin mielialan aikana vaste surullisiin kasvoihin oli suurempi kuin neutraaleihin kasvoihin. Subliminaalisessa tilanteessa neutraalit kasvot aiheuttivat suuremman N170-vasteen kuin surulliset kasvot.

Kuitenkin, surullinen mieliala vaikuttaa vain k\u00e4ytt\u00e4ytymisen tasolla, mutta N170 vaste surullisiin kasvoihin ei eroa vasteesta neutraaleihin kasvoihin.

In addition, face-sensitive event-related potential N170 is typically enhanced for sad faces in depressed individuals compared to healthy controls. In the current study we explored how induced sad mood affects the detection of facial expressions and N170 in healthy participants. Participants attended two different measurement days where they were induced sad or neutral mood. In a facial recognition task neutral and sad faces were presented subliminally and supraliminally to the participants who were instructed to decide whether the face they saw was neutral or sad. The results indicated that the accuracy was better when mood was congruent with facial expression (sad and neutral), but only in subliminal condition. Neutral faces were also more often misjudged as sad when in sad mood compared to neutral mood. Results for the N170 indicated, that in supraliminal\n \ntrials, the amplitude was enhanced for sad faces during neutral mood, compared to neutral faces. Nonetheless, N170 was larger for subliminal neutral faces compared to sad faces. The results suggest that healthy participants show negatively biased judgment of subliminal neutral facial expressions when in sad mood. However, sad mood affects behavioral level but it doesn\u2019t enhance N170 for sad faces compared to neutral faces.
