    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Emotion; facial EMG; facial reactions; facial expressions; rapid responses; automatic responses; phobia; social fear; speech anxiety; Psychology; Psykologi;

    Sammanfattning : The present thesis investigated the relationship between rapid facial muscle reactions and emotionally relevant stimuli. In Study I, it was demonstrated that angry faces elicit increased Corrugator supercilii activity, whereas happy faces elicit increased Zygomaticus major activity, as early as within the first second after stimulus onset.
