Document Summary
Next pair shown and pattern repeated: functional purpose for animals: learning one"s place without having to fight with everyone in a social group, prediction: species with a linear dominance hierarchy should be especially successful at transitive inference, species that perform well: monkeys, chimps, rats, pigeons (though not all for the same reasons), based on a linear representation of numerosity (same with people) (cid:224) inference like performance when lists are linked. B valued over d because b appears more often with positive stimuli (a), while d appears more with negative stimuli (e: not conclusive whether this is based on a linear representation or not, hippocampally lesioned rats could still learn a list of odor pairs but did not perform above chance on b vs. d tests, whereas intact rats did (cid:224) concluded that rats rely on spatial representation of the whole list.
