Tables & Figures (cogpsych-tables-figures)
In Cognitive Psychology the central exhibit usually shows the model fitting the data — observed
patterns with the model's predictions overlaid — because the contribution is the model, not the bare
effect. Exhibits should reveal distributions and uncertainty, report parameter estimates with
intervals, and let a reader judge model comparison at a glance. Bars of means hide exactly what
this venue cares about.
When to trigger
- Designing the main model-fit figure or a model-comparison table
- Deciding what goes in the article vs. the supplementary material / appendix
- A reviewer found an exhibit unclear, or said "show the fit, not just the means"
- Visualizing distributions, individual data, model predictions, and uncertainty
Principles
-
Overlay model on data. The headline figure shows observed data (with uncertainty) and the
model's predicted curve/points superimposed, ideally for the rival model too, so the reader sees
which account tracks the data. This is the venue's signature exhibit.
-
Show the data and uncertainty. Prefer distributions/individual points with means and
confidence/credible intervals over bar-of-means plots; for model parameters, plot estimates with
intervals.
-
Make model comparison legible. A table reports each model's fit (AIC/BIC/BF or cross-validated
score), free-parameter count, and the winning criterion — so the comparison is checkable, not
asserted.
-
Self-contained. Titles, notes, axes, Ns, trial counts, units, and "intervals are 95% CIs/CrIs"
make each exhibit intelligible alone, following the journal's (Elsevier/APA-style) conventions.
-
Reproducible + accessible. Generated by the deposited model/analysis code so values match;
colorblind-safe and grayscale-legible.
Worked micro-example — the main model-fit figure (illustrative)
For the recognition-memory program, the primary figure must show the fit, not the means.
Figure 1. Observed and model-predicted z-ROCs, Experiments 1-3.
Geometry: observed confidence-ROC points with 95% CIs, UVSD predicted
curve overlaid (solid) and DPSD predicted curve overlaid
(dashed) — the reader sees UVSD track the linear z-ROC.
Panels: one per experiment; shared axes for comparison.
Annotation: z-ROC slope 0.78 [0.72, 0.84]; dBIC = 14 favoring UVSD.
Note: defines the ROC metric, Ns, trials/bin, exclusion count, and
that bands are 95% intervals - readable without the main text.
Source: rendered by the deposited model-fitting script so values match.
Table 1. Model comparison: free parameters, -2logL, AIC, BIC, BF, by model.
Exhibit triage — article vs. supplementary material
| Exhibit |
Home |
Reason |
| Observed data + model fit (headline) |
main text |
this is the contribution |
| Model-comparison table (criteria + k) |
main text |
the comparison must be checkable |
| Parameter-recovery / model-recovery plots |
supplement |

| Full per-subject fits |

Exhibit-stage reviewer pushback and the venue fix
- "Bar chart hides the spread" → switch to distribution/points + intervals; show individual data where N
allows.
- "Show the fit, not the means" → overlay model predictions (and the rival's) on the observed data.
- "I can't compare the models from this" → add the model-comparison table with criteria and parameter
counts.
- "Figure values don't match Table 1" → regenerate both from the single deposited model script.
Exhibit calibration anchors
- The figure that wins a Cognitive Psychology paper is the one where the reader sees one model track
the data and the rival miss; design for that, not for a decorative bar chart.
- Show parameter estimates with intervals so the model's psychological claims are inspectable, and put
recovery plots in the supplement so the comparison is trustworthy.
- Make the model-comparison table do real work: free-parameter counts and a penalized criterion guard
against the "better fit = overfitting" objection before a reviewer raises it.
- Accessibility is part of credibility: colorblind-safe palettes and grayscale-legible line styles so
the model-vs-data distinction survives printing.
Execution bridge (StatsPAI / Stata MCP)
Generate exhibits from the fitted result, not by retyping numbers (the usual source of
body-vs-supplement drift). 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.
-
Tables:
etable (multi-model columns) or did_summary_to_latex straight from the
result_id.
-
Figures:
plot_from_result / enhanced_event_study_plot / event_study_table —
axis units and the SE/clustering note baked in.
-
Every note names the estimator + clustering and states the effect size in
interpretable units.

Anti-patterns
- Bar plots of means that hide distribution, uncertainty, and the fit
- A results figure with no model overlay in a model-driven paper
- Asserting a model "fits best" with no comparison table (criteria + parameter counts)
- Exhibits that need the prose to be intelligible (not self-contained)
- Figure/table values that don't match the deposited model code
