    • Attentional bias modification and pain: The role of sensory and affective stimuli 

      Todd, Jemma; Sharpe, Louise; Colagiuri, Ben (Behaviour Research and Therapy, 2016)
      There is growing evidence to support attentional bias modification (ABM) techniques such as the modified dot-probe task within the pain literature. Such techniques can help to inform theoretical models of pain by identifying ...
    • The effect of threat on cognitive biases and pain outcomes: an eye-tracking study 

      Todd, Jemma; Sharpe, Louise; Colagiuri, Ben (Wiley, 2016)
      Background: Theoretical accounts of attentional and interpretation biases in pain suggest that these biases are interrelated and are both influenced by perceived threat. A laboratory-based study was conducted to test whether ...
    • Expectancies in Double-Blind Randomised Placebo-Controlled Trials and Placebo-Induced Side Effects 

      Colagiuri, Ben (University of Sydney., 2012-07-16)
      The majority of research on the placebo effect has focused on beneficial effects in patients or participants told to expect an active treatment, but who are actually given a placebo. Two important and relatively understudied ...
    • Expectancy in double-blind placebo-controlled trials: An example from alcohol dependence 

      Colagiuri, Ben; Morley, Kirsten; Boakes, Robert A; Haber, Paul (Psychotherapy and Psychosomatics, 2009)
      Background: Double-blind placebo-controlled trials are intended to control for the impact of expectancy on outcomes. Whether they always achieve this is, however, questionable. Methods: Reanalysis of a clinical trial of ...
    • Latent Inhibition Reduces Nocebo Nausea, Even Without Deception 

      Quinn, Veronica F; Livesey, Evan J; Colagiuri, Ben (Oxford University Press, 2017)
      Background: Nocebo nausea is a debilitating and prevalent side effect that can develop after conditioning occurs between cues present in the treatment context and the experience of nausea. Interventions that retard ...
    • Nocebo Hyperalgesia, Partial Reinforcement, and Extinction 

      Colagiuri, Ben; Quinn, Veronica F; Colloca, Luana (Elsevier Publishing, 2015)
      Many studies have found evidence of conditioning-induced nocebo hyperalgesia. However, these studies have exclusively involved continuous reinforcement schedules. Thus, it is currently unknown whether nocebo hyperalgesia ...
    • Perceived treatment, feedback, and placebo effects in double-blind RCTs: An experimental analysis. 

      Colagiuri, Ben; Boakes, Robert A (Psychopharmacology, 2010)
      In double-blind randomized placebo-controlled trials (RCT) of therapeutic interventions, the effects of the treatment may provide feedback that undermines blinding and consequently distorts measures of the effectiveness ...
    • Placebo caffeine reduces withdrawal in abstinent coffee drinkers 

      Mills, Llewellyn; Boakes, Robert A; Colagiuri, Ben (SAGE Choice, 2016)
      Background: Expectancies have been shown to play a role in the withdrawal syndrome of many drugs of addiction. However no studies have examined the effects of expectancies across a broad range of caffeine withdrawal symptoms, ...
    • The placebo effect: from concepts to genes 

      Colagiuri, Ben; Schenk, Lieven A; Kessler, Michael D; Dorsey, Susan D; Colloca, Luana (Elsevier Publishing, 2015)
      Despite its initial treatment as a nuisance variable, the placebo effect is now recognized as a powerful determinant of health across many different diseases and encounters. This is in light of some remarkable findings ...
    • Towards a new model of attentional biases in the development, maintenance, and management of pain 

      Todd, Jemma; Sharpe, Louise; Johnson, Ameika; Perry, Kathryn N; Colagiuri, Ben; Dear, Blake F (Williams & Wilkins, 2015)
      Individuals with chronic pain demonstrate attentional biases towards pain-related stimuli. However, the clinical importance of these biases is yet to be determined and a sound theoretical model for explaining the role of ...
