Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting In 1946, Tolman etΒ al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze...

Can humans & animals really use internal maps to take shortcuts?

Tolman famously said yes - based largely on his Sunburst maze.

Our new review & meta-analysis suggests evidence is far weaker than you might think.

PhD Position on computational modelling and neuroscience (m/f/d)

We are hiring a new Ph. D. student on neuroimaging and/or computational modeling on motivation and emotion. TΓΌbingen is a great place to pursue work on these topics!!

Your stomach called – your striatum picked up!

But does this actually happen in humans?

Using simultaneous dopamine PET/fMRI, we show that the gut hormone ghrelin helps the brain adjust motivation to current metabolic need.

These findings point to larger issues surrounding the challenges of isolating associative mechanisms among humans (see also McLaren et al., 2019) as well as the extent to which associative learning could plausibly serve as the foundation of "higher-order" cognition (see also Lind, 2018)

(2) At least among humans, associative learning mechanisms might not reliably preclude switch costs (maybe because task switching itself functions as a declarative task set).

(1) Whereas pigeons appear to be "true" associative learners, our human II-learners may have actually been rule-users. This possibility accords with a growing body of literature suggesting that RB and II tasks might not reliably encourage distinct learning mechanisms. Alternatively ...

When trained to switch either between two RB tasks (thought to encourage declarative rule use) or two II tasks (thought to encourage associative learning), humans showed clear switch costs in both task conditions, whereas pigeons showed them in neither. This difference suggests that ...

New paper! Associative learning mechanisms are often overlooked in studies of "complex" cognitive processes. Here, we examined how they participate in humans' and pigeons' task-switching.

Human motivation to protect them falls five times faster than cockatoos' motivation to open them, and increasing protections makes cockatoos better at it.

πŸš€ New paper! We just took a major step in understanding how architecture shapes cognition.

Our paper shows that something as simple as corners in rooms or corridors can shift canonical spatial attention cueing costs.

Key method? Mobile Brain/Body Imaging combined with VR!
