A field experiment was conducted to evaluate whether mindfulness produces higher affective forecasting accuracy. Participants were randomized into a mindfulness-task, control-task, or baseline condition and then forecasted their positive and negative affect upon completion of an exam and upon receiving the exam grade. They also predicted their exam score. Those in the mindfulness-task condition more accurately predicted positive and negative affect upon exam completion and more accurately predicted negative affect and exam performance upon receiving their actual exam grade. Dispositional mindfulness predicted more accuracy in forecasting negative affect upon exam completion. Results suggest that mindfulness produces higher affective forecasting accuracy, particularly for negative affect. However, evidence was more mixed when considering the dispositional mindfulness results and for positive affect. 相似文献

Temporal discount rates are often poor predictors of behaviors that we expect will be motivated by the future. The current research suggests this may be because conventional discounting measures are poor measures of the motivational value of future rewards. In six studies, I develop motivation-based measures of the present value (PV) of future rewards and compare the PVs obtained with those obtained using conventional money-based discounting measures. Conventional money-based PVs consistently overestimate motivation-based PVs and are discriminable from them. I explore explanations for this mismatch, including timing of effort exertion (Study 2) and loss aversion (Study 3), both features of the motivation-based measures. In Study 5, I use self-reports of valuation strategies and a time pressure manipulation to demonstrate that participants use different valuation strategies in the conventional money-based and the motivation-based measures that, in part, determine the difference in PVs obtained and the relatively low correspondence between them. 相似文献

In an earlier article (see J Gen Philos Sci (2009) 40: 357–372) I have discussed the arguments brought forward by Michael Wolff against the interpretation given in the commentary by Ebert and Nortmann on Aristotle’s syllogistic theory (Aristoteles Analytica Priora Buch I, übersetzt und erläutert von Theodor Ebert und Ulrich Nortmann. Berlin 2007) and against the critique of Kant’s adaption of the syllogistic logic. I have dealt with Wolff’s arguments concerning (Ebert/Nortmann’s interpretation of) Aristotle in the paper mentioned and with his attempts to defend his critique in this subsequent article (part 1; see J Gen Phils Sci (2010) 41: 215–231). Part 2 (the paper below) is concerned with Wolff’s renewed attempts to defend Kant as a logician. In particular I point out that if, as Wolff claims, the nota notae relation in Kant is restricted to subordinated concepts, then it can hardly serve as a principle for syllogistic logic, as Kant claims. Against Wolff’s attempts to defend Kant’s claim that o-propositions are simpliciter convertible, I point out two arguments: (1) Even if Kant, following the Vernunftlehre by Meier, has assumed that an o-proposition can be turned into an i-proposition, this conversion is useless for the reduction to first figure syllogisms since we are no longer dealing with three syllogistic terms but with four. (2) It is quite unlikely that Kant has a conversion of this type in mind since the texts of his students always talk of the group of either the particular propositions or else of the negative propositions. Given Kant’s mistakes concerning the convertibility simpliciter of o-propositions, it is no wonder that he overlooks the special status of the moods Baroco and Bocardo. Wolff’s attempts to provide Kant with what he claims are direct proofs for these moods can be shown to rely on a reductio ad impossibile. Kant mistook what are parts of the proofs for the validity of moods in figures two to four as parts of these moods themselves. Wolff—who tries to defend Kant on this point—is forced to an artificial and unconvincing reading of the Kantian texts. 相似文献
