同伴侵害对青少年问题性网络游戏使用的影响:一个有调节的中介模型

采用问卷法对1401名青少年进行调查研究,考察了同伴侵害对青少年问题性网络游戏使用（Problematic online game use,POGU）的影响,同时考察了学业自我效能感在其中的中介作用,以及该过程是否受到父母知情的调节。结果发现：（1）在控制了性别、年龄和家庭社会经济地位（SES）后,同伴侵害仍可显著正向预测青少年POGU;（2）同伴侵害不仅可以直接正向预测青少年POGU,还可以通过影响学业自我效能感进而间接预测青少年POGU;（3）父母知情显著调节同伴侵害影响青少年POGU的直接效应,较高的父母知情可以缓冲同伴侵害的负面效应;（4）父母知情显著调节中介模型的后半段（学业自我效能感→POGU）,即低水平的父母知情放大了低学业自我效能感对青少年POGU的风险效应。

The role of urgency and its underlying psychological mechanisms in problematic behaviours

The urgency facet of impulsivity, that is, the tendency to act rashly in response to intense emotional contexts [Cyders, M. A., & Smith, G. T. (2008). Emotion-based dispositions to rash action: positive and negative urgency. Psychological Bulletin, 134, 807-828], has been related to a wide range of maladaptive behaviours. The present study further investigates the role of urgency in problematic behaviours by considering distinct psychological mechanisms that may underlie this component of impulsivity. With this aim, 95 volunteer participants were screened with self-reported questionnaires assessing urgency and three problematic behaviours (compulsive buying, excessive mobile phone use, excessive Internet use). They performed two laboratory tasks: a stop-signal task designed to assess the capacity to inhibit prepotent responses in response to both neutral and emotional stimuli; and the Iowa Gambling Task (IGT) measuring the ability to take into account the future consequences of an action. A poor ability to inhibit prepotent responses in the emotional condition of the stop-signal task was found to predict more disadvantageous choices in the IGT, which ultimately results in higher urgency and more problematic behaviours. These findings shed new light on the construct of urgency, its related psychological mechanisms, and its role in problematic behaviours.     

Decomposition of multivariate utility functions in non-additive expected utility theory

In expected utility many results have been derived that give necessary and/or sufficient conditions for a multivariate utility function to be decomposable into lower-dimensional functions. In particular, multilinear, multiplicative and additive decompositions have been widely discussed. These utility functions can be more easily assessed in practical situations. In this paper we present a theory of decomposition in the context of nonadditive expected utility such as anticipated utility or Choquet expected utility. We show that many of the results used in conventional expected utility carry over to these more general frameworks. If preferences over lotteries depend only on the marginal probability distributions, then in expected utility the utility function is additively decomposable. We show that in anticipated utility the marginality condition implies not only that the utility function is additively decomposable but also that the distortion function is the identity function. We further demonstrate that a decision maker who is bivariate risk neutral has a utility function that is additively decomposable and a distortion function q for which q(½) = ½.     

Dealing with missed opportunities: Action vs. state orientation moderates inaction inertia

Inaction inertia refers to the effect that missing a more attractive opportunity decreases the likelihood to act on an attractive current opportunity in the same domain. We studied the influence of how people cope with negative decision outcomes (i.e., action vs. state orientation) on this inaction inertia effect. Experiment 1 used an experimental induction of action vs. state orientation and confirmed our prediction that state oriented people showed more inaction inertia than action oriented people. Experiment 2 replicated these results with a measure of chronic action orientation and showed a mediating effect of valuation of the current opportunity. Experiment 3 showed that temporal segregation of the current from the missed opportunity decreased inaction inertia effects for state oriented, but not for action oriented people. We discuss the implications of these results for the inaction inertia and action vs. state orientation literatures.     

Decision by sampling: The role of the decision environment in risky choice

Decision by sampling (DbS) is a theory about how our environment shapes the decisions that we make. Here, I review the application of DbS to risky decision making. According to classical theories of risky decision making, people make stable transformations between outcomes and probabilities and their subjective counterparts using fixed psychoeconomic functions. DbS offers a quite different account. In DbS, the subjective value of an outcome or probability is derived from a series of binary, ordinal comparisons with a sample of other outcomes or probabilities from the decision environment. In this way, the distribution of attribute values in the environment determines the subjective valuations of outcomes and probabilities. I show how DbS interacts with the real-world distributions of gains, losses, and probabilities to produce the classical psychoeconomic functions. I extend DbS to account for preferences in benchmark data sets. Finally, in a challenge to the classical notion of stable subjective valuations, I review evidence that manipulating the distribution of attribute values in the environment changes our subjective valuations just as DbS predicts.

Subjective expected utility without preferences

This paper proposes a theory of subjective expected utility based on primitives only involving the fact that an act can be judged either “attractive” or “unattractive”. We give conditions implying that there are a utility function on the set of consequences and a probability distribution on the set of states such that attractive acts have a subjective expected utility above some threshold. The numerical representation that is obtained has strong uniqueness properties.     

情绪与决策的关系

该文对情绪与决策关系的研究进行了较为全面的阐述：早期的决策理论完全排斥情绪的影响作用,研究者们热衷于建立理性决策的数学模型;自Kahneman和Tversky提出前景理论后,产生了以预期情绪为主的后悔和失望理论,以及主观预期愉悦理论;20世纪90年代后,随着神经科学和社会心理学家们对情绪与认知关系研究的深入,一些学者意识到决策过程中不仅存在作为效用的预期情绪,还存在“即时”情绪,它们可以在没有认知评估参与的情况下产生,可以反过来影响认知评估,可以直接影响决策行为。     

Personality traits associated with problematic and non-problematic massively multiplayer online role playing game use

This research investigated the associations between personality traits and both normal and problematic massively multiplayer online role playing game (MMORPGs) play, as measured by a self report scale. A total of 225 participants completed the online questionnaire, 66 of whom played MMORPGs. Correlational analyses indicated that low levels of functional impulsivity and agreeableness alongside high levels of verbal aggression and video game dependency were associated with greater amount of time spent playing MMORPGs. When comparing problematic and non-problematic MMORPG players directly, problematic players were found to be lower in self regulation, dysfunctional impulsivity and agreeableness, suggesting that these traits may be important in the development and maintenance of problematic MMORPG use.     

Disclosure and rationality: Comparative risk information and decision-making about prevention

With the growing focus on prevention in medicine, studies of how to describe risk have become increasing important. Recently, some researchers have argued against giving patients “comparative risk information,” such as data about whether their baseline risk of developing a particular disease is above or below average. The concern is that giving patients this information will interfere with their consideration of more relevant data, such as the specific chance of getting the disease (the “personal risk”), the risk reduction the treatment provides, and any possible side effects. I explore this view and the theories of rationality that ground it, and I argue instead that comparative risk information can play a positive role in decision-making. The criticism of disclosing this sort of information to patients, I conclude, rests on a mistakenly narrow account of the goals of prevention and the nature of rational choice in medicine.
