A Memory I Regret

Regret as autobiographical memory.

We apply an autobiographical memory framework to the study of regret. Focusing on the distinction between regrets for specific and general events we argue that the temporal profile of regret, usually explained in terms of the action-inaction distinction, is predicted by models of autobiographical memory. In two studies involving participants in their sixties we demonstrate a reminiscence bump f...

Regret Matching with Finite Memory

We consider the regret matching process with finite memory. For general games in normal form, it is shown that any recurrent class of the dynamics must be such that the action profiles that appear in it constitute a closed set under the “same or better reply” correspondence (CUSOBR set) that does not contain a smaller product set that is closed under “same or better replies,” i.e., a smaller PC...

Adaptive Regret Minimization in Bounded-Memory Games

Online learning algorithms that minimize regret provide strong guarantees in situations that involve repeatedly making decisions in an uncertain environment, e.g. a driver deciding what route to drive to work every day. While regret minimization has been extensively studied in repeated games, we study regret minimization for a richer class of games called bounded memory games. In each round of ...

Looking back with regret: Visual perspective in memory images differentially affects regret for actions and inactions

Tattoos: a lasting regret.

occurred shortly after a femur of a 12 year old achondroplastic dwarfwas shortened by 2 cm. Multiple fat emboli were shown at necropsy.3 Certain features peculiar to our case contributed to the outcome. The patient had undergone previous operations to release his hip contractures which had resulted in dense fibrous thickening of the posterior capsule. Thus closed manipulation rather than surgic...
