Habits are the behavioral output of two brain systems. A stimulus-response (S-R) system that encourages us to efficiently repeat well-practiced actions in familiar settings, and a goal-directed system concerned with flexibility, prospection, and planning. Getting the balance between these systems right is crucial: an imbalance may leave people vulnerable to action slips, impulsive behaviors, and even compulsive behaviors.

Article Synopsis
  • Model-based planning helps prevent reliance on habits and is less effective in individuals with high compulsivity, although the impact is small and task-dependent.
  • A new diamond-shooting smartphone game was designed to measure model-based planning in a home environment, assessing how different game structures affect measurement reliability and validity related to compulsivity.
  • The study found that using fewer trials could effectively measure model-based planning, especially when tasks were less deterministic, suggesting the app is a viable tool for identifying compulsive behavior in the general population.

Metacognitive biases have been repeatedly associated with transdiagnostic psychiatric dimensions of 'anxious-depression' and 'compulsivity and intrusive thought', cross-sectionally. To progress our understanding of the underlying neurocognitive mechanisms, new methods are required to measure metacognition remotely, within individuals over time. We developed a gamified smartphone task designed to measure visuo-perceptual metacognitive (confidence) bias and investigated its psychometric properties across two studies (N = 3410 unpaid citizen scientists, N = 52 paid participants).

Online methods have become a powerful research tool, allowing us to conduct well-powered studies, to explore and replicate effects, and to recruit often rare and diverse samples. However, concerns about the validity and reliability of the data collected from some platforms have reached crescendo. In this issue, Burnette et al.
