What it does

Cogpsych Data Analysis is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when analyzing data and fitting/comparing models for a Cognitive Psychology (Elsevier) manuscript. The journal expects principled model fitting and comparison (AIC/BIC/Bayes factors), parameter and model recovery, (generalized) linear mixed models or hierarchical Bayesian estimation where apt, and effect sizes with uncertainty — all reproducible from shared code. Guides the analysis and modeling; it does not fabricate results.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Data analysis. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cogpsych Data Analysis loads about 2k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 763 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when analyzing data and fitting/comparing models for a Cognitive Psychology (Elsevier) manuscript. The journal expects principled model fitting and comparison (AIC/BIC/Bayes factors), parameter and model recovery, (generalized) linear mixed models or hierarchical Bayesian estimation where apt, and effect sizes with uncertainty — all reproducible from shared code. Guides the analysis and modeling; it does not fabricate results.

Data Analysis & Model Fitting (cogpsych-data-analysis)

Cognitive Psychology holds analyses to a model-based standard: fit the formal model, compare it to rivals with principled criteria, demonstrate that parameters and models are recoverable, use mixed models or hierarchical Bayesian estimation where the design demands it, and report effect sizes with uncertainty for behavioral results — all regenerable from deposited code. This is the experiment-to-model-fit loop that defines the venue.

When to trigger

  • Fitting the formal model and comparing it to rival accounts
  • Running the behavioral analyses (mixed models, hierarchical Bayesian, contrasts)
  • A reviewer asked for model comparison, recovery, robustness, or fuller disclosure
  • Preparing analysis/model code and a data dictionary for deposit

Reporting norms Cognitive Psychology expects

  1. Fit and compare models, don't just fit one. Report fit for your model and the rival(s) under matched flexibility; compare with AIC/BIC, cross-validation, or Bayes factors as appropriate, and say what the comparison licenses.
  2. Show recovery. Demonstrate parameter recovery (can the fitting procedure recover known parameters from simulated data) and model recovery (does the comparison criterion pick the generating model) — without these, a fit edge is not interpretable.
  3. Use the right hierarchical structure. Crossed random effects over subjects and items call for (generalized) linear mixed models; for cognitive models, hierarchical Bayesian estimation pools strength across participants. Justify the structure; don't aggregate away the variance.
  4. Effect sizes + uncertainty for behavior. Report standardized/unstandardized effect sizes with confidence/credible intervals for key behavioral results, not just p-values and stars.
  5. Confirmatory vs. exploratory. Separate pre-committed model comparisons and tests from exploratory model exploration; do not present a post hoc winning model as predicted.
  6. Reproducible. Model and analysis code, with seeds and pinned versions, regenerate every reported fit, figure, and table in a fresh session (see cogpsych-open-science-and-transparency).

Robustness

  • Show the conclusion survives reasonable alternative model specifications, priors (for Bayesian fits), and exclusion choices; report sensitivity, not a single fragile fit. Report convergence diagnostics (e.g., R-hat, ESS) for Bayesian models.

Worked micro-example (illustrative numbers)

A preregistered three-experiment recognition-memory program fitting UVSD vs. DPSD to confidence-ROC data.

Model comparison (preregistered) — pooled across Exps 1-3
  Fit (hierarchical Bayesian, matched flexibility):
    UVSD favored: dBIC = 14 vs. DPSD; Bayes factor ~ 30 in favor of UVSD
  Recovery (required): parameter recovery good (recovered d', sigma within
    credible intervals); model recovery ~ 92% correct at the design's N/trials
  Diagnostic signature: z-ROC slope 0.78, 95% CrI [0.72, 0.84], and linear
    (no reliable curvature) — the qualitative pattern UVSD predicts and DPSD
    forbids, consistent across all three experiments
Behavioral effect (mixed model)
  List-strength manipulation on d': b = 0.31, 95% CI [0.18, 0.44]
Exploratory (labeled)
  A small response-bias drift surfaced post hoc; reported as exploratory

Why this passes Cognitive Psychology scrutiny: the model is compared (not just fit), recovery makes the comparison interpretable, the qualitative signature corroborates the fit index, hierarchy respects subject/item variance, and the exploratory drift is honestly demoted.

Calibration anchors

  • A model that is fit, compared, and recovered is the unit of evidence here — a single fit with a good index but no rival and no recovery is not persuasive.
  • Trust a crossed qualitative prediction over a marginal fit advantage; report both and lead with the signature the rival forbids.
  • Respect the data's hierarchy: aggregating over subjects or items inflates false positives and can bias parameter estimates; use mixed/hierarchical models and justify the random-effects structure.
  • For Bayesian fits, report priors, convergence, and sensitivity — a fit without diagnostics is not reproducible evidence.

Execution bridge (StatsPAI / Stata MCP)

Run the battery, don't just enumerate it. Full map: execution-with-mcp. Cognitive Psychology is experimental — within-subject designs and mixed models dominate; report the model, the effect size, and multiple-comparison control.

  • Many outcomes / specifications: romano_wolf (step-down FWER) or benjamini_hochberg — report the adjusted threshold.
  • OVB sensitivity: oster_delta / sensemakr.
  • Inference: wild_cluster_bootstrap (few clusters), twoway_cluster / conley; multilevel data → cluster at the right level.
  • Re-fit off one handle: audit_result(result_id) lists the missing checks and the exact suggest_function for each.
  • Exhibits: etable / did_summary_to_latex from the handle — no retyped numbers.

Keep the decisive checks in the body and the exhaustive battery in the supplement. See the executed chain in the JF execution walkthrough.

Anti-patterns

  • Fitting only your model with no rival and no comparison criterion
  • Claiming a fit advantage without matched flexibility, recovery, or cross-validation
  • Aggregating to cell means and ignoring crossed subject/item variance
  • p-values and stars with no effect size or interval for behavioral results
  • Presenting a post hoc winning model as a predicted result
  • Model/analysis code that does not regenerate the reported fits
