How psychological momentum changes in athletes during a sport competition

ObjectivesThe present research sought to examine changes in psychological momentum (PM) during sport competitions through the lens of a dynamical systems approach.DesignMale regional-level cyclists competed in cycling duels on home trainers.MethodImages of moving avatars of the cyclists were projected on a wall, and were manipulated so that one cyclist was exposed to an ascending performance scenario (i.e., positive momentum) and the other to a descending performance scenario (i.e., negative momentum). Every 3 min, the cyclists answered PM items by using a keyboard that was placed on the handlebars of their bicycles. Additionally, exerted power was continuously recorded.ResultsResults revealed an asymmetrical critical boundary pattern for PM perceptions indicating that negative PM was triggered more easily than positive PM. Exerted power was generally higher during the negative momentum scenario than during the positive momentum scenario. In addition, exerted power slowly decreased over both momentum scenarios, and this decrease was faster at the very beginning of the negative momentum scenario.ConclusionResults indicate that PM perceptions possess the dynamical properties of nonlinearity and history-dependence. Moreover, the finding that exerted power was higher in the negative momentum scenario was interpreted as a resistance behavior that occurs while experiencing negative momentum. The anticipated decreases in both exerted power and PM perceptions in the negative momentum scenario converge to support the notion that negative PM is a stronger attractor than positive PM. The present study confirms that PM is a dynamical phenomenon and offers fruitful avenues for future research.     

Plausible Reasoning and the Resolution of Quantifier Scope Ambiguities

Despite overwhelming evidence suggesting that quantifier scope is a phenomenon that must be treated at the pragmatic level, most computational treatments of scope ambiguities have thus far been a collection of syntactically motivated preference rules. This might be in part due to the prevailing wisdom that a commonsense inferencing strategy would require the storage of and reasoning with a vast amount of background knowledge. In this paper we hope to demonstrate that the challenge in developing a commonsense inferencing strategy is in the discovery of the relevant commonsense data and in a proper formulation of the inferencing strategy itself, and that a massive amount of background knowledge is not always required. In particular, we present a very effective procedure for resolving quantifier scope ambiguities at the pragmatic level using simple quantitative data that is readily available in most database environments.     

Testing the Ideology of Openness: The Comparative Effects of Talking,Writing, and Avoiding a Stressor on Rumination and Health

A persistent assumption across the psychological literature is that talking and writing about one's stress is inherently more beneficial than avoiding it. This study compared the effects of these stress management strategies on personal and relational health. Two hundred and fifty‐one dating individuals focused on a stressor that was a current source of rumination. Writing about one's stressor for 5 consecutive days (without talking about it) decreased anxiety the most. Talking continuously about one's stressor to a dating partner harmed the relationship more than writing about or avoiding it. The effect of talking repeatedly about one's stressor on relationship quality and brooding, however, depended upon the emotional support received from one's dating partner and the ability to reappraise (positively or neutrally) the stressor.     

How Red,Blue, and Green are Affectively Judged

The present study aimed at examining how the colors red, blue, and green were affectively judged through three variables: dominance, arousal, and pleasure. All participants were exposed to red, blue, green, and white (control condition), which were created using the hue–saturation–value color model. Then, participants were invited to rate their perceptions using the self‐assessment manikin. Results showed that (a) red was strongly associated with dominance and arousal; (b) blue was moderately and slightly associated with dominance and arousal, respectively; (c) green was slightly associated with arousal; and (d) blue and green were slightly more pleasurable than red. These results provide initial insights into how people perceive colors through the notions of dominance, arousal, and pleasure. Important practical implications for the use of colors are discussed.

Reasons for,and consequences of,revealing personal secrets in close relationships: A longitudinal study

This investigation examines whether individuals’ reasons for keeping secrets predict whether they eventually reveal those secrets and whether individuals can accurately anticipate the outcomes of revealing. Respondents (n= 342) first reported on a secret they were keeping and then returned 2 months later to report whether they had revealed it and, if so, what happened when they did. Findings indicated that participants’ reasons for keeping a secret predicted whether they revealed it. The results also indicated both accuracy and inaccuracy in secret tellers’ expectations of the outcomes of revealing a secret. Finally, despite some demonstrable inaccuracies in the forecasted outcomes, participants’ retrospective accounts after revealing suggested that participants typically believed that they had accurately predicted the consequences of revealing.     

Repetitive transcranial magnetic stimulation may induce language switching in bilingual patients

The dorsolateral prefrontal cortex (DLPFC) may participate in the process of language switching in multilingual individuals. We present two cases of bilingual patients who experienced unexpected language switching after receiving high-frequency, repetitive transcranial magnetic stimulation (rTMS) to the left DLPFC as a treatment for major depression. These preliminary findings support the role of the DLPFC in language switching in polyglots and highlight the potential value of rTMS for non-invasively investigating language function in humans. Further investigation is warranted.     

A New VNS Metaheuristic Using MADS as a Local Optimizer

We propose a new hybrid metaheuristic VNSMADS that is an implementation of the Variable Neighbourhood Search (VNS) algorithm with the Mesh Adaptive Direct Search (MADS) as the local search. Because MADS is a Derivative‐Free Optimization method, the targeted problems may be non‐smooth on black box functions possessing several local optima. Constraints other than bounds on the variables are not considered. VNSMADS is applied on a real‐world problem from Finance: the portfolio selection problem using the investor preferences. Numerical results show the efficiency of our approach. Copyright © 2012 John Wiley & Sons, Ltd.     

Couple Identity Gaps,the Management of Conflict,and Biological and Self‐Reported Stress in Romantic Relationships

This study investigates the role of couple identity gaps in romantic partners' communicative and physiological management of stress during a conflict‐inducing discussion task. A total of 118 couples participated in a laboratory study in which they engaged in a conflict‐inducing discussion. Perceptions of intra‐ and extrarelationship couple identity gaps were associated with greater self‐reported anxiety and stress for men and greater negativity for women during the conversation. Extrarelationship identity gaps were also significantly associated with heightened cortisol and (salivary alpha‐amylase) sAA reactivity and delayed recovery, especially for women. The study extends the research on couple identity by introducing the concept of identity gaps into relational contexts to help explain why couples vary in their ability to manage stress.     

The Chilling Effect and Family Secrets

Two studies were conducted to test a theoretical model of the psychological and communicative links that mediate the impact of the chilling effect on the continued concealment of secrets in families. More specifically, we argued that individuals' continued concealment of a secret from aggressive family members would be mediated by the desire for protection (both of self and others). It was also hypothesized that the need for protection would negatively influence whether people felt that they had the communication efficacy to reveal their secret to these family members, which would also foster continued concealment. The results from Study One suggested that protection mediated the connection between family members' aggression and individuals' concealment of secrets from them. In addition, regardless of whether people believed they could communicate the secret to aggressive family members or not, they were likely to continue to conceal the secret if they were afraid that it would either hurt themselves or others. Results from follow up interviews in Study Two verified the model and also elaborated on the role of communication efficacy in this process.
