Can we train our pain?

My study comprehensively compares two training methods for pain reduction, aiming to change either attention to pain or perceptions about pain. I investigate the mechanisms underlying pain sensitivity reduction induced by these trainings, by employing multidimensional assessment including emotional, cognitive, and physiological measures. I will also use machine learning methods to evaluate whether individual characteristics can predict the beneficiaries of one specific training.

Cognitive Training Using Machine Learning

Cognitive training comprises a class of relatively new therapeutic interventions that target mechanisms implicated across different mental health conditions. Cognitive training programs are designed to enhance emotional functioning, either directly by cultivating different strategies for emotional processing and/or responses or indirectly by bolstering cognitive control processes in a non-emotional context, which in turn should improve emotional functioning.

Although many recent studies indicate that cognitive training shows merit, others fail to demonstrate its efficacy. These inconsistent findings may at least partly result from differences in individuals’ ability to benefit from cognitive training in general, and from specific training types in particular. Consistent with the move toward personalized medicine, we propose using machine learning approaches to help optimize cognitive training gains. More specifically, machine learning algorithms are incorporated to identify which individuals will be most responsive to cognitive training in general and to discern which methods may be a better fit for certain individuals.

Using machine-learning for prediction of anxiety and depression

Anxiety and depression are distinct – albeit overlapping – psychiatric diseases, currently diagnosed by self-reported-symptoms. This research presents a new diagnostic tool, which rigorously tests for differences in cognitive biases among anxious and depressed individuals. A comprehensive behavioral test battery quantifies various cognitive biases. Advanced machine-learning tools, developed for this study, analyzed these results. These tools detect unique patterns that characterize anxiety versus depression to predict group membership. The analysis also discloses which specific behavioral measures contributed to the prediction, pointing to key cognitive mechanisms in anxiety versus depression. These results lay the ground for improved diagnostic instruments and more effective and focused individually-based treatment.
