      <p><i>Background - </i>Fear of pain is highly correlated with pain report and physiological measures of arousal when pain is inflicted. The Fear of Pain Questionnaire III (FPQ-III) and The Fear of Pain Questionnaire Short Form (FPQ-SF) are self-report inventories developed for assessment of fear of pain (FOP). A previous study assessed the fit of the FPQ-III and the FPQ-SF in a Norwegian non-clinical ...
    • The effects of brief mindfulness training on attentional processes: mindfulness increases prepulse facilitation but not prepulse inhibition 

      Åsli, Ole; Johansen, Martha; Solhaug, Ida (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)
      Mindfulness is intentional focus of one’s attention on emotions, thoughts, or sensations occurring in the present moment with a nonjudgmental attitude. Recently there has been increased interest in the effects of mindfulness practice on psychological processes such as concentration, focus, and attention. In the present study, a prepulse inhibition/facilitation (PPI/PPF) paradigm was employed to ...
    • The Fear of Pain Questionnaire-III and the Fear of Pain Questionnaire-Short Form: a confirmatory factor analysis 

      Vambheim, Sara Magelssen; Lyby, Peter Solvoll; Aslaksen, Per M.; Flaten, Magne; Åsli, Ole; Martinussen, Laila Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-08)
      <i>Background</i>: The Fear of Pain Questionnaire-III (FPQ-III) is a widely used instrument to assess the fear of pain (FOP) in clinical and nonclinical samples. The FPQ-III has 30 items and is divided into three subscales: Severe Pain, Minor Pain and Medical Pain. Due to findings of poor fit of the original three-factor FPQ-III model, the Fear of Pain Questionnaire-Short Form ...
    • In the Blink of an Eye: Investigating the Role of Awareness in Fear Responding by Measuring the Latency of Startle Potentiation 

      Åsli, Ole; Flaten, Magne Arve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The latency of startle reflex potentiation may shed light on the aware and unaware processes underlying associative learning, especially associative fear learning. We review research suggesting that single-cue delay classical conditioning is independent of awareness of the contingency between the conditioned stimulus (CS) and the unconditioned stimulus (US). Moreover, we discuss research that argues ...
    • In Your Face: Startle to Emotional Facial Expressions Depends on Face Direction. 

      Åsli, Ole; Michalsen, Henriette; Øvervoll, Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01)
      Although faces are often included in the broad category of emotional visual stimuli, the affective impact of different facial expressions is not well documented. The present experiment investigated startle electromyographic responses to pictures of neutral, happy, angry, and fearful facial expressions, with a frontal face direction (directed) and at a 45 angle to the ...
    • Model Gender Interacts With Expressed Emotion to Enhance Startle: Angry Male and Happy Female Faces Produce the Greatest Potentiation 

      Åsli, Ole; Øvervoll, Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-09)
      Several studies have implied gender differences in startle reaction to emotional facial expressions. However, few studies have been designed to investigate the difference between responding to emotional female vs. male faces, nor gender differences in responses. The present experiment investigated startle EMG responses to a startle probe while viewing pictures of neutral, happy, angry, fearful, and ...
    • Nocebo hyperalgesia and the startle response 

      Aslaksen, Per M.; Åsli, Ole; Øvervoll, Morten; BjØrkedal, espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-24)
      Background: The literature on the effects of nocebo on pain is sparse. The present experimental study investigated whether suggestions of nocebo hyperalgesia modified the startle response and whether increased startle contributed to the nocebo hyperalgesic effect. Methods: A design with four groups was employed; the participants were randomized into either a placebo group, a natural history group, ...
