We examined the influence of self-regulatory focus on the anticipation of regret in the context of life decisions. Eager promotion-focused individuals consider different negative outcomes to be more relevant than do vigilant prevention-focused individuals (e.g., non-gains vs. losses). We proposed that the two regulatory foci would elicit more regret for different negative decision consequences ...

Both affective neuroscience and decision science focus on the role of emotions in decisions. Regret and disappointment are emotions experienced with negative decision outcomes. The present research examines the neural substrates of regret and disappointment as well as the role of regret and disappointment in decision making. Experiment 1 compared the subjective experience of regret and disappoi...

Regret is a cognitively mediated, multifaceted emotion engendered by thoughts of how things might have been better had we behaved differently. The causes, experience and behavioural impact of regret have been widely studied by psychologists. However, research into the neural basis of regret has been motivated primarily by economic approaches, which often reduce regret to such a simplistic const...

Mirror descent with an entropic regularizer is known to achieve shifting regretbounds that are logarithmic in the dimension. This is done using either a carefullydesigned projection or by a weight sharing technique. Via a novel unified analysis,we show that these two approaches deliver essentially equivalent bounds on a no-tion of regret generalizing shifting, adaptive, discount...

Past research has established a connection between regret (negative emotions connected to cognitions about how past actions might have achieved better outcomes) and both depression and anxiety. in the present research, the relations between regret, repetitive thought, depression, and anxiety were examined in a nationally representative telephone survey. although both regret and repetitive thoug...

Recent fMRI studies have investigated brain activity involved in the feeling of regret and disappointment by manipulating the feedback participants saw after making a decision to play certain gambles: full-feedback (regret: participant sees the outcomes from both the chosen and unchosen gamble) vs. partial-feedback (disappointment: participant only sees the outcome from chosen gamble). However,...

We explore the construction of nonsubjective prior distributions in Bayesian statistics via a posterior predictive relative entropy regret criterion. We carry out a minimax analysis based on a derived asymptotic predictive loss function and show that this approach to prior construction has a number of attractive features. The approach here differs from previous work that uses either prior or po...

The expectation–confirmation model (ECM) of continued information systems (IS) use has proven to be successful across online service contexts. Previous studies based on ECM have focused on a referent (i.e., comparison standard) that is centered on the target IS (i.e., target online service). The effect of this referent, captured through confirmation, has been strongly demonstrated. Yet, few stu...

Recently, there has been a growing research interest in the analysis of dynamic regret, which measures the performance of an online learner against a sequence of local minimizers. By exploiting the strong convexity, previous studies have shown that the dynamic regret can be upper bounded by the path-length of the comparator sequence. In this paper, we illustrate that the dynamic regret can be f...
