Amazing PsyCoder

AI-powered toolkit for psychology experiment coding and statistical analysis, from task design to reproducible workflows.

What it does

Amazing PsyCoder removes coding barriers from psychology research by automating experiment design, code generation, and statistical analysis. It guides researchers through structured workflows—from initial hypothesis to publishable results—without requiring programming expertise.

How it works

The skill uses seven integrated components: a task orchestrator plus six specialized sub-skills covering experiment programming and data analysis. For experiments, it guides you through design confirmation → code generation → code auditing. For data analysis, it routes you through analysis design → script generation → reproducibility checking.

Supports PsychoPy (Python), jsPsych (JavaScript), and Psychtoolbox (MATLAB) for experiment creation. For analysis, generates R (tidyverse/lme4) or Python (pandas/statsmodels) reproducible scripts. Covers 38 classic paradigms (Stroop, N-back, IAT, etc.) and 60+ statistical methods.

Use cases

  • Experiment design: Convert research ideas into working task code in hours instead of weeks
  • Data analysis: Match your scientific question to optimal statistics with transparent decision logic
  • Lab reproducibility: Generate auditable code that runs identically across environments
  • Methodology transparency: Create design registries and analysis plans reviewers can verify

Who benefits

Psychology students and researchers building experimental tasks, behavioral scientists needing systematic analysis workflows, labs seeking reproducible research infrastructure, and anyone currently struggling with RT accuracy, randomization, or statistical method selection.

Frequently asked questions

How do I install Amazing PsyCoder?
In Claude Code, paste: Install Amazing PsyCoder for me: https://github.com/soupandpsy/amazing-psycoder-skills. For other platforms (Codex, Hermes, OpenClaw), use their respective skill installation commands with the same GitHub URL. Terminal users can run: git clone https://github.com/soupandpsy/amazing-psycoder-skills && cd amazing-psycoder-skills/amazing-psycoder && ./install.sh
What programming languages do I need to know?
None. Amazing PsyCoder generates all code automatically. You only answer design questions in plain language (e.g., "I need a Stroop task with red/green/blue colors, 50% congruent trials, 2 blocks of 60"). The skill handles Python (PsychoPy), JavaScript (jsPsych), MATLAB (Psychtoolbox), R, or Python code generation.
What's the difference between PsychoPy, jsPsych, and Psychtoolbox?
PsychoPy (Python): Best for lab studies needing millisecond RT precision via USB. jsPsych (JavaScript): Best for online studies—runs in any browser without installation. Psychtoolbox (MATLAB): Best for studies requiring frame-perfect timing and GPU control. Amazing PsyCoder supports all three; the skill recommends based on your requirements.
Can it handle my specific experimental paradigm?
Amazing PsyCoder covers 38 classic paradigms: Stroop, flanker, N-back, Simon, Stop-signal, go/no-go, IAT, BART, task switching, and many more. Each has built-in logic for trial windows, randomization, and counterbalancing. If your design is a variant of these, the skill adapts automatically. For entirely novel designs, it guides you through custom specification.
How does it choose the right statistical test?
The analysis designer skill evaluates your data across 12 dimensions: design (within/between/mixed), sample size, normality, sphericity, effect size distribution, and others. It compares 60+ methods (t-tests, ANOVA, mixed models, Bayesian, etc.) and explains why one fits better. You see the trade-offs before code generates.
Will my results be reproducible across computers?
Yes. Generated code uses explicit random seeds, documents all dependencies, and produces identical results when re-run. Analysis scripts use R Markdown or Jupyter notebooks so reviewers can execute your exact pipeline. The auditing skill checks for environmental inconsistencies before delivery.
Can I modify the generated code?
Absolutely. Generated code is production-ready but fully editable. All parameters are labeled at the top of scripts. If you modify the code, re-run the auditing skill to check for new issues. The skill treats customized code as a new version for review.
How long does it take to generate an experiment?
Typically 15-30 minutes for simple paradigms (Stroop, N-back) including design confirmation and code review. Complex multi-block designs with custom counterbalancing may take 45 minutes. Data analysis takes 20-40 minutes depending on design complexity and method selection discussion.

Glossary

Reaction Time (RT)
The interval from stimulus onset to valid response. Amazing PsyCoder ensures RT is logged from the correct trial window (e.g., stimulus presentation start, not fixation start).
Trial Window / Timeline
Sequence of display events within one experimental trial (e.g., fixation → stimulus → response window → feedback). The skill visualizes this as a diagram so timing ambiguities are resolved before coding.
Counterbalancing
Systematic variation of stimulus properties (e.g., color-word mappings) across trials or blocks to prevent order effects. Amazing PsyCoder auto-generates randomized or Latin-square balanced conditions.
Mixed Model / Hierarchical Linear Model
Statistical approach treating both fixed effects (experimental conditions) and random effects (subject/item variability). Recommended when designs nest observations within participants, replacing traditional ANOVA for modern analysis.
Reproducibility Audit
Automated code review checking for common errors (hardcoded paths, missing seeds, undocumented assumptions) that break results across environments. The skill iterates until code passes all checks.
