These inconsistencies are likely exacerbated by the challenge of high\u2010dimensional data (i.e., many variables per subject), which is common across neuropsychological paradigms and necessitates analytical advances. More unique to OCD is the heterogeneity of symptom presentations, each of which may relate to distinct neuropsychological features. While researchers have traditionally attempted to account for this heterogeneity using a symptom\u2010based approach, an alternative involves focusing on underlying symptom motivations. Although the most studied symptom motivation involves fear of harmful events, 60\u201370% of patients also experience sensory phenomena, consisting of uncomfortable sensations or perceptions that drive compulsions. Sensory phenomena have received limited attention in the neuropsychological literature, despite evidence that symptoms motivated by these experiences may relate to distinct cognitive processes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Here, we used a supervised machine learning approach to characterize neuropsychological processes in OCD, accounting for sensory phenomena.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared to logistic regression and other algorithms, random forest best differentiated healthy controls (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a059; balanced accuracy\u00a0=\u00a0.70), patients with sensory phenomena (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a029; balanced accuracy\u00a0=\u00a0.59), and patients without sensory phenomena (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a046; balanced accuracy\u00a0=\u00a0.62).
