This article explores a female university volleyball student-athlete’s experience with protracted concussion symptoms. Through the methodology of narrative inquiry, four salient themes became apparent related to Daphnée’s experiences: (a) “I felt so alone,” (b) “I had to make one of the hardest decisions of my life,” (c) “I feel like I’m in prison,” and (d) “There’s no light at the end of the tunnel.” Overall, this study offers a rare look into the impact of concussion on an individual’s athletic and academic identities, career progression, and in turn, her imagined stories of who she was and who she was becoming. 相似文献

The prospect of consumable meat produced in a laboratory setting without the need to raise and slaughter animals is both realistic and exciting. Not only could such in vitro meat become popular due to potential cost savings, but it also avoids many of the ethical and environmental problems with traditional meat productions. However, as with any new technology, in vitro meat is likely to face some detractors. We examine in detail three potential objections: 1) in vitro meat is disrespectful, either to nature or to animals; 2) it will reduce the number of happy animals in the world; and 3) it will open the door to cannibalism. While each objection has some attraction, we ultimately find that all can be overcome. The upshot is that in vitro meat production is generally permissible and, especially for ethical vegetarians, worth promoting. 相似文献

Alexithymia is a personality trait associated with the reduced ability to regulate, identify, and communicate feelings or
emotions and is often linked to psychosomatic disorders. The present study used event-related potentials (ERPs) to investigate
the relationship between individual differences in alexithymia and emotion regulation. Participants classified as scoring
either high or low on the revised form of the Toronto Alexithymia Scale (TAS-20; Taylor, Bagby, & Parker Psychother Psychosom
57:34–41, 1992) were asked to view negative and neutral images, adopting three different regulation strategies (expressive suppression,
cognitive reappraisal, and attend) while ERPs were recorded. Results revealed an inverse relationship between TAS scores and
emotion-related ERP activity during suppression, but not during reappraisal or a control “attend” condition. These results
were observed in both early and late ERP latencies. These findings are interpreted according to potential differences between
high- and low-TAS individuals regarding the frequency of prior utilization of suppression-based regulation strategies. 相似文献

Alterations in the perception of body signals (i.e., interoceptive awareness [IA]) are considered crucial for the development and maintenance of somatoform disorders (SFDs). However, competing theories come to different conclusions about whether IA is increased or decreased in SFDs. The present study investigated IA in 23 patients with SFDs (as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and in 27 healthy controls. IA was reliably assessed with two well-established heartbeat perception paradigms (heartbeat discrimination task and mental tracking task). The results of both paradigms showed no evidence for increased IA in patients with SFDs. Correlational analyses revealed that having a higher number of somatoform symptoms was significantly linked to lower (rather than higher) IA in SFDs. These findings are in line with recent cognitive approaches to SFDs that stress the importance of biased schema-guided processing of interoceptive information.

The emotional enhancement of memory is often thought to be determined by attention. However, recent evidence using divided attention paradigms suggests that attention does not play a significant role in the formation of memories for aversive pictures. We report a study that investigated this question using a paradigm in which participants had to encode lists of randomly intermixed negative and neutral pictures under conditions of full attention and divided attention followed by a free recall test. Attention was divided by a highly demanding concurrent task tapping visual processing resources. Results showed that the advantage in recall for aversive pictures was still present in the DA condition. However, mediation analyses also revealed that concurrent task performance significantly mediated the emotional enhancement of memory under divided attention. This finding suggests that visual attentional processes play a significant role in the formation of emotional memories. 相似文献

Visual cerebral lateralization over phases of the menstrual cycle: a preliminary investigation 总被引:2,自引:0,他引:2
This study investigated whether visual cerebral asymmetries would change in phase with hormonal variations during the menstrual cycle. Lexical decision and line orientation tasks were administered during follicular, luteal, and menstrual phases of each woman's cycle. These tasks were also administered to a reference group of male subjects. Signal detection analyses indicated an unvarying RVF advantage in word/nonword discriminability (d') throughout the menstrual cycle, but a phase-dependent shift in left hemisphere response criterion (log beta). Gender differences were present for discriminability of line orientation, and female performance on this task varied over the cycle. The results imply that the neural systems subserving some cognitive functions are sensitive to fluctuations in gonadal steroids and suggest a hormonal basis for gender differences in some visual-spatial functions. 相似文献

Cortical function was evaluated in 26 subjects with spasmodic dysphonia. Quantitative topographic electrophysiologic mapping (QTE) was employed to provide quantitative analyses of EEG spectra and auditory and visual long-latency evoked potentials. Single-photon emission computed tomography (SPECT) of the cerebral transit of Xenon-133 was used to evaluate regional cerebral blood flow. Left hemispheric abnormalities in cortical function were found by both techniques in 10 subjects and by at least one technique in 18 subjects. Right hemispheric abnormalities were observed by both techniques in 8 subjects and by at least one technique in 18 subjects. Most patients with cortical dysfunction in one hemisphere had cortical dysfunction in the other, while only 4 subjects had unilateral lesions as found by one of the two techniques. Eight subjects were normal by all measurements. Underlying structural abnormalities were detected by magnetic resonance imaging in 5/24 subjects. However, functional abnormalities (SPECT or QTE) were not observed at sites of structural abnormalities. SPECT and QTE were significantly related in identification of left hemispheric dysfunction (p = .037) with a trend in the right hemisphere (p = .070), and a significant congruence of SPECT and QTE findings occurred in the left anterior cortical quadrant (p = .011). These findings indicate that dysfunction of cortical perfusion and/or cortical electrophysiology is associated with spasmodic dysphonia in the majority of subjects studied. 相似文献
