Dispositional and induced optimism lead to attentional preference for faces displaying positive emotions: An eye-tracker study

The aim of this study was to examine whether dispositional optimism and induced optimism are associated with an attentional bias for positive stimuli. Fifty-six healthy participants performed an eye-tracking task twice, while their gazing time at faces displaying joy, anger, pain, or a neutral expression was measured. Participants scoring high on dispositional optimism tended to gaze longer at joy faces during the first face-presentation trial compared to participants scoring lower on optimism, and this correlation became significant during the second face-presentation trial. In between the two presentations, participants received either an optimism manipulation or a control manipulation. There was no effect of type of manipulation on gazing behavior but post hoc analyses demonstrated that participants showing an increase in state optimism displayed a significant decrease in gaze duration for anger faces and a nearly significant increase in gaze duration for joy faces.

Image Manipulation as Research Misconduct

A growing number of research misconduct cases handled by the Office of Research Integrity involve image manipulations. Manipulations may include simple image enhancements, misrepresenting an image as something different from what it is, and altering specific features of an image. Through a study of specific cases, the misconduct findings associated with image manipulation, detection methods and those likely to identify such manipulations, are discussed. This article explores sanctions imposed against guilty researchers and the factors that resulted in no misconduct finding although relevant images clearly were flawed. Although new detection tools are available for universities and journals to detect questionable images, this article explores why these tools have not been embraced.

What’s Wrong with Motive Manipulation?

Consider manipulation in which one agent, avoiding force, threat, or fraud mobilizes some non-concern motive of another so as to induce this other to behave or move differently than she would otherwise have behaved or moved, given her circumstances and her initial ranking of concerns. As an instance, imagine that I get us to miss the opening of a play that I have grudgingly agreed to attend by engaging your sublimated compulsive tendency to check the stove when we are halfway to the theatre. Such motive manipulation is, I take it, widely regarded as morally worrisome. If it really is morally worrisome, then we should be able to explain adequately why it is so. But existing condemnations of manipulation come up short in this regard. In this paper, I develop and defend a more plausible account of the moral status of this phenomenon.

The Relevance of Intention in Argument Evaluation

The paper discusses intention as a rhetorical key term and argues that a consideration of rhetor’s intent should be maintained as relevant to both the production and critique of rhetorical discourse. It is argued that the fact that the critic usually has little or no access to the rhetor’s mind does not render intention an irrelevant factor. Rather than allowing methodological difficulties to constrain critical inquiry, I suggest some ways in which the critic can incorporate the rhetor’s intention in evaluating argumentation. To this end, a standard of fairness is presented. The paper was presented at the 6th International Conference on Argumentation in Amsterdam, June 27–30, 2006.     

Rapid learning of syllable classes from a perceptually continuous speech stream

To learn a language, speakers must learn its words and rules from fluent speech; in particular, they must learn dependencies among linguistic classes. We show that when familiarized with a short artificial, subliminally bracketed stream, participants can learn relations about the structure of its words, which specify the classes of syllables occurring in first and last word positions. By studying the effect of familiarization length, we compared the general predictions of associative theories of learning and those of models postulating separate mechanisms for quickly extracting the word structure and for tracking the syllable distribution in the stream. As predicted by the dual-mechanism model, the preference for structurally correct items was negatively correlated with the familiarization length. This result is difficult to explain by purely associative schemes; an extensive set of neural network simulations confirmed this difficulty. Still, we show that powerful statistical computations operating on the stream are available to our participants, as they are sensitive to co-occurrence statistics among non-adjacent syllables. We suggest that different learning mechanisms analyze speech on-line: A rapid mechanism extracting structural information about the stream, and a slower mechanism detecting statistical regularities among the items occurring in it.     

Experimentally manipulated change in children's proactive and reactive aggressive behavior

The current study assessed the effectiveness of two behavior manipulations created to differentially lower aggressive responses in a laboratory task. It was hypothesized that the reactive anger manipulation would have the greatest effect for reactive aggressive behavior and the instrumental manipulation would significantly affect proactive aggressive behavior and slightly affect the reactive behavior. Fifty participants played pinball in competition for points against an unknown peer, whose responses were actually controlled by the experimenter. Participants could push a noise button, sending the peer an annoying noise; a tilt button, interfering with the opponent's game; or a no answer button, offering a pro‐social alternative to aggression. After playing four rounds, participants were randomly assigned to either a reactive anger or a positive instrumental manipulation group; they then played pinball again for four rounds. Results indicate that the instrumental manipulation significantly lowered aggressive responses for both reactive and proactive behavior. The reactive manipulation effected aggressive responses only for use of the noise button and produced significantly lower levels of anger. Aggr. Behav. 29:215–227, 2003. © 2003 Wiley‐Liss, Inc.     

Towards a structural ownership condition on moral responsibility

In this paper, I propose and defend a structural ownership condition on moral responsibility. According to the condition I propose, an agent owns a mental item if and only if it is part of or is partly grounded by a coherent set of psychological states. As I discuss, other theorists have proposed or alluded to conditions like psychological coherence, but each proposal is unsatisfactory in some way. My account appeals to narrative explanation to elucidate the relevant sense of psychological coherence.     

网络公益平台默认选项设置对个人捐赠意愿的影响及作用机制

本文探讨了在网络公益背景下默认选项金额对个人捐赠意愿的影响及其心理机制。通过4个实验, 本文发现在网络公益平台中将默认选项设置为高金额会显著地减少个人的捐赠意愿, 而感知被操控在该影响过程中起到了中介作用。具体而言, 当公益机构将默认选项的金额设置为高金额(vs. 低金额)时, 人们的被操控感知增强, 进而捐赠意愿降低, 产生了默认效应的反作用。此外, 个体道德认同水平在这一影响中发挥了调节作用。当个体道德认同水平较低时, 高金额默认选项(vs. 低金额默认选项)会降低其捐赠意愿, 而对于道德认同水平较高的个体而言, 他们的捐赠意愿在高/低金额默认选项时不存在显著差异。研究结论推进了默认效应在捐赠决策领域的理论研究, 同时对于当前快速发展的网络公益平台进行捐赠金额的设置具有重要的实践意义。     

Variability and creativity in small-sided conditioned games among elite soccer players

ObjectiveSmall-sided conditioned games (SSCG) in soccer are games with a small number of players, often played on smaller than regular pitches and with adapted rules. It has been argued that SSCG foster soccer players’ physical, technical and tactical performances and creativity. This study tested the latter conjecture by analysing video-footage of individual actions of elite soccer players in 5 v 5, 6 v 6, 7 v 7 SSCG played during regular training sessions and 11-aside training matches. Based on the ecological dynamics approach, we hypothesized that smaller formats would result in players making more individual actions. We additionally anticipated that the smaller formats players would induce a larger repertoire of actions, that is, an increased variability of actions, and that such increase in variability would be associated with more creative actions. Along the same lines, we reasoned that midfielders would make more creative actions than defenders and attackers.MethodWe categorized 3555 soccer actions on the ball and without the ball of 24 elite soccer players.ResultsPlayers produced more actions in smaller SSCG formats compared to the larger SSCG format and the 11-aside match. They also produced more different actions in SSCG than the 11-aside match. Furthermore, ten creative actions (i.e., actions that were adequate and only made by one or two players) were discerned. The creative actions emerged most often in the smaller SSCG, and were absent in the 11-aside matches. Finally, strikers, defenders and midfielders did not show reliable differences in terms of number, variability and creativity of action.ConclusionSSCG in soccer do indeed stimulate variability and creativity of individual actions. It is important to confirm whether these immediate effects of SSCG generalize across longer time scales.
