Tools for Teaching and Research

By David Allbritton
Updated October 13, 2026

These are some apps and web pages I have created for use in research or for demonstrations in teaching.

Also see my GitHub and OSF pages for source code and additional resources.

Shiny apps (R)

Some of these apps also have versions that run entirely in your browser, with no server needed.

• https://dallbrit.shinyapps.io/dataSimulationWithScales/ - tool for generating simulated data for a 2x2 design, for use in research methods or statistics courses
• https://dallbrit.shinyapps.io/ResearchMethodsDataSimulation_one_IV/ - tool for generating simulated data for a one IV design, for use in research methods or statistics courses
• https://dallbrit.shinyapps.io/Breathing_Life_into_MetaAnalysis/ - tool for creating a living meta-analysis using both frequentist and Bayesian methods. Published in Journal of Cognition, 2024, https://doi.org/10.5334/joc.389
• https://dallbrit.shinyapps.io/Meta_regression_app/ - an updated version of the meta-analysis tool that can do meta-regression and more (use this version instead of the archival one from the article)
• https://dallbrit.shinyapps.io/RescorlaWagnerDemo/ - demo of the Rescorla-Wagner Model of Classical Conditioning
• https://allbritton-depaul.shinyapps.io/CI_model_demo/ - demo of one step in Kintsch’s Construction-Integration Model of text comprehension
  (also here: https://dallbrit.shinyapps.io/Construction_Integration_Model_Demo)
• https://allbritton-depaul.shinyapps.io/regressionToTheMean/ - demo of regression to the mean
  (also here: https://dallbrit.shinyapps.io/regressionToTheMean)
• https://dallbrit.shinyapps.io/odds_to_proportions/ - tool to help students relate odds to proportions

Javascript apps and web pages

• Bayes Theorem Nomogram - likelihood ratio nomogram for updating prior probabilities in light of new evidence
• Bayes Factor / Likelihood Ratio - visualizing and calculating a Bayes Factor (or likelihood ratio) to quantify the strength of new evidence, with explanatory text
• Seidenberg & McClelland (1989) Demos - demos of the connectionist network from Seidenberg & McClelland (1989)
• Serial Position Effect Demo - study a list, recall it in any order, and see which list positions you remembered best
• Sternberg (1966) Memory Scanning Demo - try both experiments from Sternberg’s “High-speed scanning in human memory” and compare your reaction times with his
• Stimulus Suffix Effect Demo - hear spoken lists of digits that end in a tone or a spoken “baa” and compare recall of the last item, with notes on Neath, Surprenant & Crowder (1993)
• Stroop Effect Demo - name ink colors aloud on a quick 15-word card and on Stroop’s (1935) four card tests, then measure interference and facilitation trial by trial
• Word List Memory Demo (Roediger & McDermott, 1995) - hear six short word lists, take a memory test, then see an explanation of the results
• Phonemic Restoration Demonstration - demonstration of the “phonemic restoration” perceptual illusion in speech perception
• Thinking like a Bayesian - a brief introduction to Bayesian reasoning, with useful links
• Analyzing Reaction Time Data - lecture outline and links to resources for dealing with outliers, non-normality
