Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden
Psychophysiology 40:989-97. 2003..However, because effects were observed even for participants who reported unawareness of the contingency from trial order, results are consistent with the notion of hunches or gut feelings... - Keeping it short: a comparison of methods for brief picture presentationStefan Wiens
Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden
Psychol Sci 15:282-5. 2004..However, our results may not generally apply to all displays, so we advise researchers to validate the presentation parameters of their displays.

Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden
Emotion 4:340-53. 2004..Thus, a shift from top-down control to an affectively driven system optimized for speed was observed in phobic relative to fear-relevant aware processing... - Social interaction, cardiovascular activation and the Type A behavior patternT Palm
Department of Rehabilitation Medicine, Karolinska Hospital, Sweden
Int J Psychophysiol 13:101-10. 1992..There were no main effects of Type A vs. Type B, but dyads composed of two Type As showed larger increase in diastolic blood pressure during the conflict phase of the task compared to dyads composed of Type Bs... - Has evolution primed humans to "beware the beast"?Arne Ohman
