`/neuroflow:preregistration`¶

Create and manage pre-registration documents.

/preregistration helps you commit your study design, hypotheses, and analysis plan to a public registry before data collection begins — and manage any subsequent deviations from that plan.

When to use it¶

You want to pre-register your study on OSF or AsPredicted
You want to check an existing pre-registration for completeness and internal consistency
A deviation from the pre-registered plan occurred and needs to be logged
You want to record the details of a submitted or accepted registered report

What it does¶

Claude reads your project memory (.neuroflow/ideation/ and .neuroflow/experiment/) for the research question, hypothesis, and paradigm details, then asks which mode applies:

Draft pre-registration — produce a complete pre-registration for OSF, AsPredicted, or a registered report journal
Review pre-registration — check an existing document for completeness and consistency
Deviation log — record and justify any post-registration change to the plan
Link registered report — record the DOI, URL, or registry ID of a submitted or accepted registered report

Draft pre-registration¶

Claude asks which registry and template you are targeting:

OSF (standard)AsPredictedRegistered report

Covers all required OSF preregistration fields:

Section	Content
Title & authors	Project title and team
Description	Study overview
Hypotheses	Directional, falsifiable predictions
Design	Variables, conditions, randomisation, blinding
Participants	Population, sample size, inclusion/exclusion, power calculation
Procedure	Timeline, instruments, paradigm
Measures	Operationalisation of each variable
Analysis plan	Statistical tests, correction strategy, missing data handling
Exploratory analyses	Clearly labelled non-confirmatory tests
Data sharing	Availability and access plan

Covers the six AsPredicted fields:

Hypothesis and study question
Dependent variable(s)
Conditions
Analyses
Outliers and exclusions
Sample size and rationale

Structured for stage 1 submission to a journal. Claude asks for the target journal's specific section requirements.

Output: prereg-[registry]-[date].md saved to .neuroflow/preregistration/

Review pre-registration¶

Claude reads your existing pre-registration document and checks:

Is the hypothesis directional and falsifiable?
Are all analysis steps fully specified?
Is the sample size justified by a power calculation?
Are exclusion and missing-data rules defined before data collection?
Are exploratory analyses clearly distinguished from confirmatory ones?
Is there any ambiguity that could allow selective reporting?

Output: prereg-review-[date].md saved to .neuroflow/preregistration/

Deviation log¶

When something changes after registration, Claude records:

What was pre-registered
What actually happened
Why the deviation occurred
How it affects interpretation of results

Output: appended to deviations.md in .neuroflow/preregistration/ (never overwritten)

Example session¶

/neuroflow:preregistration

Claude: I found your research question from /ideation:
        "Does white noise reduce P300 amplitude in a visual oddball task?"

        And paradigm details from /experiment.

        Which mode would you like?
        1. Draft pre-registration
        2. Review existing pre-registration
        3. Log a deviation
        4. Link a registered report

You: 1

Claude: Which registry?
        1. OSF (standard)
        2. AsPredicted
        3. Registered report (journal submission)

You: 1 — OSF standard

Claude: Great. Let me start with the hypotheses section.
        The hypothesis I have from /ideation is:
        "White noise will reduce P300 amplitude compared to silence."
        Is this the directional prediction you want to register?

Files read and written¶

Direction	Files
Reads	`.neuroflow/project_config.md`, `.neuroflow/flow.md`, `.neuroflow/preregistration/flow.md`, `.neuroflow/ideation/flow.md`, `.neuroflow/experiment/flow.md`
Writes	`.neuroflow/preregistration/`, `.neuroflow/preregistration/flow.md`, `.neuroflow/sessions/YYYY-MM-DD.md`

/ideation — formalize your research question and hypothesis first
/experiment — design the paradigm that goes into the methods section
/data-analyze — run the pre-registered analysis plan after data collection
