Here is Speelman and McGann’s new book critiquing modern research and statistical analysis methods in psychology. I have not yet picked up a copy, but am looking forward to reading it.
Another thoughtful and well-reasoned paper on measurement by Joel Michell — The Mystery of Missing Psychometric Corpus: The Case of the Technological Cart Before the Scientific Horse

A new paper on pervasiveness by Denis Lajoie just landed in Personality Science. Considering Approaches to Pervasiveness in the Context of Personality Psychology.
The latest version is done and posted under the download page. A suite of new procedures for analyzing proportions has been added, as well as a procedure for conducting logical hypothesis testing based on truth tables. Many of the procedures have been enhanced for speed and efficiency, and the user experience has been improved by smoother transitions across windows. The import procedures for .csv (comma separated values) files have been sped up and improved as well. Finally, various minor bugs have been cleared.
In addition, the technical manual has been completed and revised. It will download with the software along with the numerous data files used for demonstrative purposes in the manual. Its main purpose is to record for posterity the methods written into the OOM software. It was also written to help the user navigate through and understand the various analysis procedures in the software. A chapter on importing data into OOM has also been added, and a Glossary can be found at the end. Where possible, references have been added so users can see published papers that use OOM.
God willing, I will return to the Youtube channel next, tear it down, and build it back from scratch.

I have another paper out with Ian Jones: Iconic Models in Science and Psychology in Theory & Psychology. Sometimes a picture truly is worth a thousand words.
My erstwhile student, Ian Jones, has a new paper out on word learning in children. With his co-authors, he re-analyzed archival data to answer novel questions that were not addressed by traditional statistical procedures (t-test, ANOVA, regression). If your data are not continuous, why not look for patterns in individual discrete responses rather than analyze means and variances? Here’s the paper: Jones, Kucker, Perry, and Grice (2024). Capturing the Heterogeneity of Word Learners by Analyzing Persons, Behavioral Sciences, 14(8), 708.
