Anyone here able to explain a formula in Wikipedia about the Tolman Paradox?

The t' definition is a mystery to me. How would we drop in c to get the unit of time? How come a is multiplied with v?

Our paper on the poor replicability of Tolman, Richie & Kalish, 1946 - the famous "Sunburst maze" - is out!
Last author @rmgrieves made a very nice thread about it here:
https://fediscience.org/@rmgrieves/115844897663215766The article: Tolman's Sunburst Maze 80 Years on: A Meta-Analysis Reveals Poor Replicability and Little Evidence for Shortcutting
I'll just add that this doesn't at all question the #CognitiveMap theory, which is quite strongly supported by diverse lines of evidence - but it shows that one of the elements previously used to support the theory, the ability to choose a shortcut over unexplored space, is not that clearly demonstrated!
Importantly, this also shows that it is crucial to consider papers in their context and to make sure results are consistently replicable before changing them into scientific facts!
PS: I managed to attract Roddy to Mastodon - it would be great to show him we can get at least as much interaction on here as with his similar thread on Bluesky

The #Tolman "sunburst maze" results (from 1946) are often used to demonstrate shortcut ability in rats... but do they really? More on this later!
For now, would you know of any #ComputationalModels that were tested in this protocol (whether they replicate the original results or not)? We know of a few (well... 4) but would like to make sure we are not missing any.
