Cognitive Dynamics of a Single Subject: 1428 Stroop Tests and Other Measures in a Mindfulness Meditation Context Over 2.5 Years

Abstract

Recent discussions on threats of group-to-individual generalisability in psychology have prompted the need for individual-level data that is of sufficient length, in order to study within-individual psychological processes. In the current study, a single participant monitored their own cognitive dynamics daily before and after a 20-minute meditation session delivered by a mobile application. Over the course of 900 days, the participant performed Stroop tests and self-reported variables regarding cognitions (e.g. mood, clarity, calm, tiredness) as well as context (e.g. sleep, fasting, coffee, self-regulation).
