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:

The 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

Schematic of the sunburst maze in its test version, with a central circular platform, a blocked "learned" path, and several radiating arms from the center, one of them is a shortcut to the food location.

Screenshot of parts of Fig3 of the paper showing, on the left, a mock "sunburst maze" with each specific path type coloured differently - the types are, in clockwise order: outer, other, other, adjacent, (greyed out training path), adjacent, shortcut, cued, outer.

On the left, a bar graph summarises the results of our meta-analysis with most studies showing a significant preference of rats for the Adjacent path, or no preference at all. The shortcut bar is 3rd with 8 experiments, and is mostly composed of human studies, Tolman et al.'s 1946 study being one of them. — Screenshot of parts of Fig3 of the paper showing, on the left, a mock "sunburst maze" with each specific path type coloured differently - the types are, in clockwise order: outer, other, other, adjacent, (greyed out training path), adjacent, shortcut, cued, outer.

Paper accepted 🥳 in #EJN European Journal of #Neuroscience :)

More on it once it's out and I can link to it!
