      Laeng, Bruno; Sæther, Line; Holmlund, Terje; Wang, Catharina E.; Waterloo, Knut; Eisemann, Martin; Halvorsen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      We used filtered low spatial frequency images of facial emotional expressions (angry, fearful, happy, sad, or neutral faces) that were blended with a high-frequency image of the same face but with a neutral facial expression, so as to obtain a “hybrid” face image that “masked” the subjective perception of its emotional expression. Participants were categorized in three groups of participants: healthy ...

      We recorded the pupil diameters of participants performing the words’ color-naming Stroop task (i.e., naming the color of a word that names a color). Non-color words were used as baseline to firmly establish the effects of semantic relatedness induced by color word distractors. We replicated the classic Stroop effects of color congruency and color incongruency with pupillary diameter recordings: ...
