Understanding Mechanisms of Behavior Change

3,942 views

Published on

The Mechanisms of Behavior Change project is studying how individuals are able to use self-control processes to reduce or quit drinking using brain imaging. The results may help us better understand the process of recovery and its relationship to addiction as a brain disease.

  • Dear sir,
    I an Addiction studies PHD student, who is searching for a good topic for her thesis and other research projects which has a psychological aspect.
    would you please help me,on my way?
    Best regards,
    Leila Rezaeian

  6. 6. Extant Cog Neuro Treatment Studies Morgenstern, Naqvi, DeBellis, & Breiter (2013) • Predictors of relapse • Identify biomarkers (morphology and/or activation) that predict relapse • Treatment effects • Develop treatments that target deficits identified by cog neuro theories (e.g., working memory) • Test whether treatment changes brain activity to better understand mechanism of treatment effect © CASAColumbia 2013 6
  7. 7. Mechanisms of Reactivity and Regulation Can Inform Treatments • Cognitive neuroscience paradigms characterize nature of the disorder (biomarkers) • Heightened reward reactivity? • Regulatory deficits? • Neural responses to component processes of behavioral treatments may relate to individual differences in treatment response • Ability to apply tailored treatments © CASAColumbia 2013 7

Emotion Regulation Process Model after Gross, 1998; Ochsner & Gross, 2005; Ochsner et al., 2012 Regulatory Processes Situation selection Stimuli in context Select situations that promote desired responses Cognitive change Situation modification Internal: thoughts, sensations, etc. External: people, cues, events, etc. © CASAColumbia 2013 Response modulation Attention Appraisal Response Change what you focus on Reappraise meaning of stimulus/event Suppress or enhance expression/b ehavior 10

Cognitive Regulation of Craving Kober, Mende-Siedlecki, Weber, Hart, Mischel, & Ochsner (2010) PNAS Think about immediate consequences of consuming… NOW How smoking would make you feel, it’s smell, it’s taste…. Think about long-term consequences of consumption… LATER Consequence for your health… Cancer, lung & heart disease…. © CASAColumbia 2013 13
  14. 14. Important to Understand Regulation • Reactivity is affected by regulation • AUD may by driven by • Heightened reactivity to cues • Impaired regulation ability • Both • Cognitive neuroscience approach allows for examination of reactivity & regulation © CASAColumbia 2013 14
