How do capuchin monkeys learn to use stones to crack open nuts? Perception-action theory posits that individuals explore producing varying spatial and force relations among objects and surfaces, thereby learning about affordances of such relations and how to produce them.

The notion that non-human animals are capable of episodic memory is highly controversial. Here, we review recent behavioral work from our laboratory showing that the fundamental features of episodic memory can be observed in rats and that, as in humans, this capacity relies on the hippocampus. We also discuss electrophysiological evidence, from…

Recounts an experiment where two groups of college students composed questions for a simulated quiz show and then answered each other's questions. They then answered questions comparing their performance with other groups. Proposes a social norm rather than attribution error explanation for the fact that groups consistently will underestimate…
