The relationship between competitive anxiety and imagery use

Abstract

Imagery has been proposed to be an effective strategy for controlling levels of competitive anxiety, but little b known about how imagery functions to achieve this. This study explored the relationship between imagery use. imagery ability. competitive anxiety and performance. Fifty-seven Junior North American Roller Skating Championship competitors completed the revised Movement Imagery Questionnaire (MIQ-R), the Sport Imagery Questionnaire (SIQ), and the Competitive State Anxiety Inventory—2 (CSAI-2). Results from stepwise multiple regression analyses revealed visual imagery ability and motivational arousal imagery to be predictors of cognitive state anxiety. Visual imagery ability also predicted somatic state anxiety. while motivational mastery imagery was a predictor of self-confidence. With respect to the relationship between imagery use and imagery ability, high imagery ability was associated with higher imagery use. Finally, self-confidence and kinesthetic imagery ability scores correctly classified a majority of the subjects as medalists versus non-medalists. These results suggest that imagery can be used to help control competitive anxiety levels and enhance self-confidence.     

The Search for Adam Revisited: Evolution,Biblical Literalism,and the Question of Human Uniqueness

Abstract

This article questions the adequacy of the philosophical category of realism in characterizing Rheticus' endorsement of Copernicus' astronomy. Rheticus and Osiander agree that the human intellect is restricted in its aspirations to truth, resulting in a condition of “causal ignorance” regarding the celestial phenomena on Rheticus' part. Copernicus' pupil advances trust in the most true hypothesis of the motion of the earth without postulating its absolute truth. Causal knowledge waits after Resurrection. In line with Luther's comment on Genesis 1:14, Rheticus ascribes a theological meaningfulness to the pursuit of mathematics, alerting the astronomer to his immortal soul and divine creation.     

Structural Equation Modeling of Spatial Presence: The Influence of Cognitive Processes and Traits

This article examines the formation process of spatial presence, which is conceived as a two-step process involving the construction of a mental model of the mediated environment, followed by the emergence of spatial presence. During both stages, cognitive processes and user traits are in effect. We present data derived from a pooled set of data of three studies using the same virtual environment. Structural equation modeling is used to confirm the proposed theoretical model. The results show that attention and the trait of visual spatial imagery are positive predictors of the mental model of the mediated environment. In the second step, the formation of spatial presence is governed by involvement, the suspension of disbelief, and the domain-specific interest, together with the mental model.     

The Impact of Adolescent Suicide on Siblings and Parents: A Longitudinal Follow-Up

The psychiatric sequelae of loss of a family member to suicide were evaluated in parents and siblings of adolescent suicide victims and controls, who were followed up to 3 years after the suicide. Siblings did not show an increased risk for the development of depression, posttraumatic stress disorder (PTSD), or other conditions over the course of follow-up, despite showing a prolonged elevated level of grief symptomatology. Mothers showed an increased rate of recurrence of depression over follow-up, whereas fathers did not show an increased incidence of disorder compared to fathers of controls. The interrelationship of bereavement and depression for siblings, parents, and others exposed to suicide is discussed.     

Muslims Love Jesus,Too? Corrective Information Alters Prejudices Against Islam

The present study examined whether prejudices towards Islam can be altered through corrective information. A total of 1715 German participants were first asked to appraise their opinions towards Judaism, Christianity and Islam (the ratings pertained to progressiveness, tolerance, peacefulness). Subsequently, questions regarding knowledge about religious topics were posed to participants. Questions were selected to elicit common prejudices pertaining to Islam. The correct answers were then displayed along with detailed explanations. Finally, participants were asked to rate their current opinion towards the three religions once again. Opinions towards Islam were largely negative at baseline but improved significantly after presentation of the correct answers. The present study suggests that prejudices against Islam are partially fueled by knowledge gaps.     

Does spatial learning ability of common voles (<Emphasis Type="Italic">Microtus arvalis</Emphasis>) and bank voles (<Emphasis Type="Italic">Myodes glareolus</Emphasis>) constrain foraging efficiency?

Place learning abilities represent adaptations that contribute also to foraging efficiency under given spatio-temporal conditions. We investigated if this ability in turn constrains decision making in two sympatric vole species: while the herbivorous common vole (Microtus arvalis) feeds on spatio-temporally predictable food resources (e.g. roots, tubers and shoots of plant tubers), the omnivorous bank vole (Myodes glareolus) additionally subsists on temporally unpredictable food resources (e.g. insects and seeds). Here, we compare the spatial reference memory and working memory of the two species. In an automated operant home cage with eight water places, female voles either had to learn the fixed position of non-depletable places (reference memory task) or learn and avoid previously visited water places depleted in a single visit (win-shift task). In the reference memory task, Microtus females required significantly more choices to find all water places, initially performed slightly worse than Myodes females, and displayed slightly lower asymptotic performance. Both species were highly similar in new learning of the same task. In the more complex win-shift task, asymptotic performance was significantly lower in Microtus (72% correct) than in Myodes (79%). Our results suggest that both vole species resemble each other in their efficiency to exploit habitats with low spatio-temporal complexity but may differ in their efficiency at exploiting habitats with temporally changing spatial food distributions. The results imply that spatial ability adjusted to specific food distributions may impair flexible use of habitats that differ in their food distribution and therefore, decrease a species’ chances of survival in highly dynamic environments.     

Encoding the goal of an object-directed but uncompleted reaching action in 6- and 9-month-old infants

Infants start to interpret completed human actions as goal-directed in the second half of the first year of life. In a series of three studies, the understanding of a goal-directed but uncompleted action was investigated in 6- and 9-month-old infants using a preferential looking paradigm. Infants saw the video of an actor's reaching movement towards one of two objects. This reaching movement was only presented until the hand passed the midpoint between the starting position and the position of the target object. Subsequently, two final states of the reaching movement were presented simultaneously. In the plausible final state, the hand grasped the object to which the reaching movement was geared; in the implausible final state, the hand grasped the other object. In Studies 1 and 3, infants watched the actor from an allocentric perspective, and in Studies 2 and 3 from an egocentric perspective. Results indicate a discrimination of the two final states if the scene was presented from an allocentric perspective: both 6- and 9-month-olds looked longer at the implausible final state. This was not the case if infants saw the action from an egocentric perspective. The presented findings show that using this paradigm, 6-month-olds are already able to infer the goal of an uncompleted action without seeing the achievement of the goal itself. However, they encoded the goal of the reaching action only when it was presented from an allocentric perspective but not from an egocentric perspective.
