What Scholexis is built on
Four findings shape how this product behaves. Each one below names the construct, the paper, what it changes in the software, and where the research stops. If you are deciding whether to recommend Scholexis to a student, the last part of each section is the part worth reading.
1 of 4
Performance at the point of performance
Barkley reframed ADHD as a disorder of performance rather than of knowledge or skill. People know what to do and cannot reliably do it at the moment it needs doing, so supplying more information does not close the gap. What helps is changing the environment at the point where the behaviour has to happen.
What it shapes here
Guidance appears where the work is, not in a manual, an onboarding tour, or a settings panel. The planning help sits on the assignment itself. The energy check-in sits on the dashboard you already opened. There is no course to complete before the product is useful.
Where it stops
Barkley's model is about ADHD; the design principle it implies is general. We apply it to interface placement, which is our extension, not his finding.

Implementation intentions
An "if-then" plan that names a concrete cue and a specific response — "When I sit down after dinner, I will open the reading and mark one passage" — produced a medium-to-large effect on goal attainment, d = 0.65, across 94 studies and more than 8,000 participants. The mechanism is that the cue takes over the job of starting, so beginning stops depending on deciding to begin.
What it shapes here
When Scholexis breaks an assignment into steps, exactly one of the first three steps is written as an if-then plan in the first person. Not every step, because a plan made entirely of triggers stops reading like a plan.
Where it stops
That d = 0.65 comes from goal-striving studies in general populations, not from ADHD randomised trials. The effect is well established for goal pursuit; its size specifically in ADHD is not what those 94 studies measured, and we do not report it as though it were.

Delay aversion and steep temporal discounting
Sonuga-Barke's dual-pathway model describes a motivational route to ADHD alongside the executive one: delay itself is aversive, so avoiding it is the behaviour, not a failure to attend. The 2016 meta-analysis of case-control studies found reliably steeper discounting of delayed rewards in ADHD. A deadline three weeks out is not weakly motivating because the student does not care; it is weakly motivating because that is how the discount curve works.
What it shapes here
What we call deadline gravity. Every assignment and task carries a pull that rises as its deadline approaches — low, rising, high, critical — and that pull, not the raw date, is what orders the day. It is a counterweight to the discount curve: it makes the near-term signal match the real stakes instead of waiting for panic to do it.
Where it stops
Discounting research describes a group-level difference in how delayed rewards are valued. It does not tell us the right curve for any individual student, and our zones are a design decision informed by that literature rather than a calibrated instrument.

Distributed practice
Study spread across days beats the same total time in one sitting, and retrieving material — actually pulling it from memory — beats rereading it. Both effects are large and among the most replicated findings in learning research.
What it shapes here
Steps are scheduled backward from the deadline across the days available, so a plan for a cumulative exam becomes several study sessions on different days rather than one block the night before. The last step lands before the due date, not on it.
Where it stops
This is the section where we have to be careful. Scholexis spaces the work. Scholexis does not run retrieval practice: it does not quiz you, generate questions, or give corrective feedback, and the schedule cannot tell whether you spent the session recalling or rereading. The spacing half is in the product; the testing half is not built, and the Roediger and Karpicke effect is about the testing half.

What we do not claim
- No outcome data. We have not measured whether students who use Scholexis get better grades, submit more work, or graduate at higher rates. Nobody has run that study, including us.
- No trial. Scholexis has not been tested in a randomised controlled trial, or any controlled trial. The findings above support the design decisions. They are not evidence about this product.
- Not treatment. Scholexis is a planning tool. It does not diagnose, does not treat, and is not a clinical intervention. It should not displace care.
- Not a substitute for accommodations. Nothing here replaces registering with a disability services office, an evaluation, or an approved accommodation. We built the transition tools precisely because those things matter and are hard to start.
- Not a documentation source. Nothing a student writes in Scholexis constitutes clinical documentation for a disability services office.
A word about spoons, which are not research
Scholexis measures effort in spoons by default. That metaphor comes from Christine Miserandino, who in 2003 explained living with lupus to a friend in a diner by handing her a fistful of spoons and taking one back for every ordinary task of the day. It belongs to the chronic-illness and disability community, which coined it, uses it, and did not need a journal to validate it.
It is a metaphor, not a construct, and we are not going to dress it up as one. It also fits fatigue-limited conditions better than it fits ADHD, where capacity does not drain at a steady rate: it rises and falls with interest, novelty, and whether the thing ever got started. We use spoons because students recognise them and because counting them is not a judgement about a person. If the word does not fit you, the unit is yours to rename in your settings.
