Waiting When Both Certainty and Magnitude Are Increasing: Certainty Overshadows Magnitude

In everyday decision making, people often face decisions with outcomes that differ on multiple dimensions. The trade‐off in preferences between magnitude, temporal proximity, and probability of an outcome is a fundamental concern in the decision‐making literature. Yet, their joint effects on behavior in an experience‐based decision‐making task are understudied. Two experiments examined the relative influences of the magnitude and probability of an outcome when both were increasing over a 10‐second delay. A first‐person shooter video game was adapted for this purpose. Experiment 1 showed that participants waited longer to ensure a higher probability of the outcome than to ensure a greater magnitude when experienced separately and together. Experiment 2 provided a precise method of comparing their relative control on waiting by having each increase at different rates. Both experiments revealed a stronger influence of increasing probability than increasing magnitude. The results were more consistent with hyperbolic discounting of probability than with cumulative prospect theory's decision weight function. Copyright © 2014 John Wiley & Sons, Ltd.     

The Intention–Behavior Gap

Bitter personal experience and meta‐analysis converge on the conclusion that people do not always do the things that they intend to do. This paper synthesizes research on intention–behavior relations to address questions such as: How big is the intention–behavior gap? When are intentions more or less likely to get translated into action? What kinds of problems prevent people from realizing their intentions? And what strategies show promise in closing the intention–behavior gap and helping people do the things that they intend to do?     

孔子思想中的君子人格：心理学测量的探索

君子人格是中国文化(尤其是儒学思想)中的理想的人格特质, 对于理解中国文化心理具有重要意义, 但鲜有实证研究。通过经典文本的理论分析与心理测量的实证分析相结合的方法, 选取《论语》中孔子对君子的论述编制初测条目, 通过探索性和验证性因素分析、效标关联效度分析等实证研究方法(总样本量 = 1916), 对孔子思想中的君子人格的内在结构进行了探索, 并编制了具有良好信效度的测量工具。结果表明, 孔子思想中的君子人格包含了智仁勇、恭而有礼、喻义怀德、有所不为、持己无争5个因素。此外还考察了其与大五人格、中国人价值观、自我和谐、合作与竞争人格倾向、亲社会倾向等效标变量的相关关系。     

Dealing with feeling: a meta-analysis of the effectiveness of strategies derived from the process model of emotion regulation

The present meta-analysis investigated the effectiveness of strategies derived from the process model of emotion regulation in modifying emotional outcomes as indexed by experiential, behavioral, and physiological measures. A systematic search of the literature identified 306 experimental comparisons of different emotion regulation (ER) strategies. ER instructions were coded according to a new taxonomy, and meta-analysis was used to evaluate the effectiveness of each strategy across studies. The findings revealed differences in effectiveness between ER processes: Attentional deployment had no effect on emotional outcomes (d(+) = 0.00), response modulation had a small effect (d(+) = 0.16), and cognitive change had a small-to-medium effect (d(+) = 0.36). There were also important within-process differences. We identified 7 types of attentional deployment, 4 types of cognitive change, and 4 types of response modulation, and these distinctions had a substantial influence on effectiveness. Whereas distraction was an effective way to regulate emotions (d(+) = 0.27), concentration was not (d(+) = -0.26). Similarly, suppressing the expression of emotion proved effective (d(+) = 0.32), but suppressing the experience of emotion or suppressing thoughts of the emotion-eliciting event did not (d(+) = -0.04 and -0.12, respectively). Finally, reappraising the emotional response proved less effective (d(+) = 0.23) than reappraising the emotional stimulus (d(+) = 0.36) or using perspective taking (d(+) = 0.45). The review also identified several moderators of strategy effectiveness including factors related to the (a) to-be-regulated emotion, (b) frequency of use and intended purpose of the ER strategy, (c) study design, and (d) study characteristics.     

The Predictive Power of Combined Neuropsychological Measures for Attention-Deficit/Hyperactivity Disorder in Children

The present study explores the predictive power of seven neuropsychological assessment tools used in combination in classifying children with attention-deficit/hyperactivity disorder (ADHD). Twenty-one ADHD boys and 22 community control children participated. Group differences were significant on the continuous performance test only; however, battery analysis did increase overall predictive power, which was moderate. This study highlights the difficulty in identifying consistent mean differences on tests of frontal/executive functioning across studies, as well as the need to assess the predictive validity of these tests in classifying children with ADHD. The study suggests that these tests may provide greater predictive validity when used in combination. Inconsistencies in the literature are discussed, with consideration of research methodology, the heterogeneity of the ADHD population, and comorbid diagnoses.     

Long-range channelling in low energy ion implantation into silicon

Abstract

Low energy (50 eV) implantation of boron and silicon into crystalline Si through the {110} and {100} faces is studied by a molecular dynamics simulation and the results compared with a binary-collision crystalline computer model and SIMS data. It is found that long-range channelling of the B particles takes place and that their ranges far exceed those predicted by transport theory in random media or Monte-Carlo computer models. It is found that channelling of B occurs only in the 〈110〉 direction. The Si atoms which are displaced by more than the nearest-neighbour spacing always originate from near to the surface as a result of direct knock-ons from ions which do not channel. These displacements show a distinct angular dependence because of the crystalline nature of the solid. For the Si implantation, the attractive forces between the incoming ion and the crystal atoms play an important role in limiting the ion range.     

Traumas With and Without a Sense of Agency

The authors differentiate two types of traumatic experience: trauma with agency and trauma without agency. The types are different despite the fact that the symptoms of both look similar enough to fall within the diagnosis of post-traumatic stress disorder (PTSD). The differentiating factor is the sufferer's sense of agency during the circumstances surrounding the trauma. What is traumatizing is that the individual acted in some way that, however adaptive in the moment of threat and crisis, was ultimately loathed simultaneously or subsequently by the person's larger self and seen by this larger self as defining of character. Traumatized clients with a sense of agency require treatment that comes from being cared for and loved despite this hated facet of self.
