Discretionary task interleaving RUNNING HEAD: DISCRETIONARY TASK INTERLEAVING Discretionary task interleaving: Heuristics for time allocation in cognitive foraging

When participants allocated time across two tasks (in which they generated as many words as possible from a fixed set of letters) they made frequent switches. This allowed them to allocate more time to the more productive task (i.e. the set of letters from which more words could be generated), even though times between the last word and the switch decision (“giving-up times”) were higher in the...

In fact, the randomness arises fr...
