Quiz: Can You Crack the Same Logic Puzzles as a Lab Rat? PopBiology Owl Apr 5, 2026 0 1. The new maze design gives rats a central platform to survey all their options before choosing – which helps scientists clearly detect when genuine deliberation is happening True False None 2. When a new pair is added to the hierarchy – say, C > D joins the mix – why do some rats' scores on already-learned pairs dip slightly? They're forgetting old information to make room for new They're quietly restructuring their entire mental ranking to absorb the new information The maze layout changes and throws them off They lose interest and stop trying None 3. In the final test, rats performed better on a brand-new, never-seen pairing (B vs. D) than they did when first learning some of the basic trained pairs True False None 4. That head-sweeping behaviour called Vicarious Trial and Error (VTE) – does it appear more when rats are confident, or when they're uncertain? When they're confident and performing well When they're uncertain, which often precedes errors Only during easy, well-practised choices It's not a real, documented behaviour None 5. Unlike older scent-based tests, this maze ensures that even the lowest-ranked option (arm E) occasionally delivers a reward. Why does that design choice matter so much? It prevents rats from simply avoiding E forever – forcing genuine understanding of the full hierarchy It speeds up training but reduces accuracy It deliberately disrupts the hierarchy to increase difficulty It doesn't really matter – it's just a minor procedural tweak None Time's up
