Nonrandomised natural experiment in 5,424 smartphone-app users undergoing 7,447 US relocations. Moving from the 25th to 75th percentile of city walkability accompanied about 1,100 more daily steps, sustained for three months; this was a large environmental contrast. Within-person and comparison analyses reduce some selection concerns, but concurrent life changes and app selection remain. Phones miss some activity; route accessibility is not measured. No ADHD analysis. Original full article checked.

Randomised crossover in 12 healthy young adults: four hours of bright tablet reading before bed for five evenings versus print in dim light. Tablet exposure delayed melatonin timing and sleep onset, reduced REM and worsened morning alertness. Total sleep and non-REM duration did not differ significantly. Intensive exposure and bundled brightness/spectrum limit generalisation; it does not isolate blue light or test ADHD. Original full article checked.

24.18 links dependent arising, emptiness, dependent designation and the middle way. 8.12 treats actor/action as mutually dependent. 24.38–39 contrasts inherent nature with change and ending suffering. Garfield translates the Tibetan and explicitly works within an Indo-Tibetan interpretive framework. Clinical agency is the author's application; the text is not ADHD evidence.

The preface identifies consulted Tibetan editions and Tsongkhapa's commentary. The document is the literal working translation, distinct from Batchelor's published free poetic version. Terminology varies from Garfield; the same root verses support dependence, contextual designation and the possibility of change. Two translations are two textual witnesses, not independent empirical studies. Wisdomlib's chapter 24 combines root verses with translated Tsongkhapa commentary, which must not be attributed wholesale to Nāgārjuna.

20 weight-stable adults; mean age approximately 31. No ADHD sample or ADHD outcomes. Participants ate approximately 508 kcal/day more on the ultra-processed menu and gained around 0.9 kg, while losing around 0.9 kg on the unprocessed menu. Presented menus were designed to match several nutrients; eating rate and non-beverage energy density differed. Small, short, controlled study of two complete menus. It does not isolate every processing mechanism, make all convenient foods harmful, establish an ADHD benefit, or test dopamine addiction. The paper has published corrections from 2019 and 2020. The original daily energy-intake result remains approximately 508 kcal/day.

Three laboratory experiments examined distress and immediate gratification. The procrastination experiment analysed 88 undergraduates: induced bad mood increased observed diversion from test preparation especially when appealing distractions were available and participants expected their mood could change. A deceptive mood-freezing instruction removed this excess procrastination. This supports expected short-term mood repair as one avoidance motive. It did not test ADHD, repeated reinforcement, deadlines in daily life, or the proposed brief awareness practice.

Eight-day experience sampling of 75 university students generated 501 paired task appraisals. Increasing perceived task unpleasantness between planning and intended action predicted greater odds of delay; increasing task value predicted less delay. Expected success also mattered, whereas estimated effort did not independently predict delay in the combined model. These within-person results closely support the feeling-tone/task-onset link. Self-report and observational design cannot establish causality; participants were not selected for ADHD or assessed for adrenaline.

Five nonclinical human experiments (analysed n=72,55,74,41,54) tested avoidance of aversive pictures or sound. Learned safety signals increased avoidance in four experiments, with a null result when the control signal was similar. Early samples used post-hoc exclusions and unregistered repeat recruitment; experiment 5 was preregistered. This supports an avoidance-learning principle, not the complete ADHD deadline loop, screen addiction or a dopamine reset.
