Cognitive Psychology expects tightly controlled cognitive experiments whose design is engineered to discriminate models, organized as a multi-experiment program in which each experiment adds inference. The craft is in stimulus construction, counterbalancing, confound control, and powering the critical contrast — not just the main effect. Co-design the experiments with the model (cogpsych-theory-and-hypotheses).
Cogpsych Study Design is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cogpsych-study-design/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when designing the experiments for a Cognitive Psychology (Elsevier) manuscript so they tightly control confounds, discriminate competing models, and have adequate power across a multi-experiment program. Hardens stimulus construction, counterbalancing, design logic, and sample-size justification; it does not write analysis or modeling code.
The Cogpsych Study Design Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 168,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/cogpsych-study-design/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Cogpsych Study Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
