Objective
The IZOF-based probabilistic approach provides a methodology to study within-individual patterns of a performer's states. So far, the time course of physiological data before performance have not been investigated within the probabilistic methodology framework. The purpose of this study was to examine the value of the probabilistic approach in the assessment of the time course of physiological indicators of arousal/activation and vigilance during the period preceding the shot, in comparison with the performance-based method.Design
Longitudinal assessment of psycho-physiological data and performance outcomes was conducted on eight elite pistol shooters in a controlled setting.Methods
Each participant performed 60 air-pistol shots in 2 sessions. Skin conductance level and cardiac activity were recorded. Affective states intensity was evaluated on a modified 11-point Borg scale. Affect, HR and SC level were evaluated with a Performance-based approach and a Probabilistic method, and results compared at an individual level.Results
Findings showed the higher effectiveness of the probabilistic method to analyse physiological parameters (skin conductance and heart rate) and to describe the physiological mechanisms associated with shooters’ performance.Conclusions
The probabilistic method better discerned the contribution of arousal/activation and vigilance to optimal and non-optimal performance in elite shooters, thereby providing a sharper representation of the temporal pattern of performers' states before shooting. From an applied perspective, we believe that the probabilistic approach can help athletes become aware of the subtle variations occurring in their psychophysical states during the preparatory period preceding the shot and not only at the moment of shot release. 相似文献182.

The current investigation examined whether attachment functioning might mediate the effects of parenting on traits associated with psychopathy. Participants completed the Parental Bonding Instrument, the Experiences in Close Relationships Scale, and the Triarchic Psychopathy Measure within a cross-sectional design. Whilst several recalled parenting variables demonstrated significant correlations with the psychopathy subscales, mediation analyses confirmed that the majority of these effects were mediated by current attachment anxiety and avoidance. Only paternal overprotection maintained a significant direct effect on levels of disinhibition. These findings provide support for the argument that attachment dysfunction may represent a potential mechanism through which parenting practices contribute to the emergence of psychopathy-related traits. Inferences regarding causality and mechanisms of effect are naturally constrained by the cross-sectional design of the current investigation, but the preliminary findings presented warrant further examination within prospective designs. 相似文献

Some aspects of executive function are thought to be dysfunctional in psychopathic individuals. We administered a small battery of neuropsychological tests (spatial alternation task, object alternation task, and Porteus Maze) to two samples of college students and obtained a measure of psychopathy via a self-report questionnaire. Psychopathic traits were related to the tests of object alternation and Porteus Maze but not to the spatial alternation task. Our results support the hypothesis of orbitofrontal cortex (OFC) dysfunction with sparing of dorsolateral prefrontal cortex (DLPFC) in psychopathy and provide a downward extension of this theory to sub-clinical levels of psychopathy. 相似文献

When adults are asked to recall their earliest autobiographical memories most can recall nothing about their infancy and early childhood, a phenomenon commonly referred to as childhood amnesia. There is general consensus regarding the existence of childhood amnesia, but there remains considerable debate over its boundary. Most researchers have argued that the boundary of childhood amnesia occurs between the ages of 3 and 4 years, but in 1993 Usher and Neisser published a highly influential paper, which has subsequently been used to argue that the boundary may be as low as 2 years. In the present experiment we examined how changes in scoring criteria influence our estimates of the age of adults’ earliest memories. We conclude that some coding criteria are more valid than others and that the best estimates of childhood amnesia will include measures of free recall in addition to the specific questions that have dominated prior research in this area. 相似文献

Abstract The study tested the model of adaptation after trauma by Benight and Bandura (2004) indicating that posttraumatic recovery may be predicted directly by coping self-efficacy (CSE) and indirectly by social support. These relations were investigated in the context of posttraumatic growth (PTG) among Hurricane Katrina survivors living with HIV. Additionally, it was hypothesized that among individuals with more intensive Posttraumatic Stress Disorder (PTSD) symptoms, those with strong CSE would experience the strongest PTG. Cross-sectional data were collected among 90 patients with HIV who reinitiated care at the HIV outpatient clinic. Questionnaires were administered approximately 14 months after the hurricane. Higher CSE was related to higher PTG among the survivors who suffered from more intensive PTSD symptoms. Received social support was directly related to only one index of PTG, relating to others. Furthermore, although there was a significant relationship between social support and CSE, the indirect conditional effect of received social support on PTG was not confirmed. Similar results were obtained across the indices of PTG, controlling for the level of exposure to hurricane-related trauma. Cross-sectional design and convenience character of the sample warrants replications. 相似文献

Although the results of previous psychological studies suggested the existence of behavioral freedom, there existed no methodology that could unequivocally identify the portion of human behavior resulting from self-determination or behavioral freedom in human action. The methodological innovations reviewed herein throw a different light on the factors involved in the genesis of human action than was previously possible with extant psychological research methodologies. But critics contend that in such studies subjects might simply be conforming to the experimenter's demands, rather than demonstrating their ability to self-determine. Two studies are presented that demonstrate that conformity is an extremely implausible explanation for the results attributed to self-determination in previous studies. Furthermore, the second study demonstrates the interaction between the idiographically construed meaningfulness of a behavior and one's desire or ability to voluntarily alter that behavior. 相似文献

This article seeks to document the characteristics and themes of later trauma recovery using a grounded theory analysis of interviews with trauma survivors enrolled in outpatient treatment. Little research exists that speaks to patients’ own accounts of the process of trauma recovery. Such accounts might elucidate how psychotherapy helps survivors make and remake meaning of their lives, their experience of traumatic events, and the resources they might call on in psychotherapy to secure recovery. This study examined narrative material gathered in a series of interviews with trauma survivors (n?=?14) who had been in treatment for an average of 8 months and could be described as in a later phase of the recovery process. Two significant themes emerged from the analysis: (a) greater coherence to the trauma narrative, and (b) the emergence of a more reflective and observational stance with respect to one's history. Implications for trauma-informed therapy are discussed. 相似文献

In this I essay I analyse four sermons delivered at Shan festivals that celebrates the end of the Rains Retreat (Waa). I first argue that sermons in general are important sources of information about lived Buddhism. I next provide background information necessary to understand the sermon events and the sermons. In conclusion, I compare the sermons and discuss what laypeople can learn from sermons and what we, as academics, can learn from them. 相似文献

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge. 相似文献
