Although correlational studies indicate that team attributes are related to athletes' precompetitive psychological states, it is unknown how team members experience these relationships. The present study's purpose was to investigate athletes' perceptions of precompetitive team influence. Consequently, we worked from a constructivist realist position and used qualitative methods (interviews with competitive team-sport athletes). An inductive content analysis revealed that athletes perceived established and novel team characteristics and processes to influence their precompetitive psychological states. Athletes perceived these influences as both adaptive and maladaptive, and it appeared that they were qualified by contextual factors as well as intuitive regulatory attempts. 相似文献

We present a case study of hierarchical Bayesian explanatory cognitive psychometrics, examining information processing characteristics of individuals with high-functioning autism spectrum disorder (HFASD). On the basis of previously published data, we compare the classification behavior of a group of children with HFASD with that of typically developing (TD) controls using a computational model of categorization. The parameters in the model reflect characteristics of information processing that are theoretically related to HFASD. Because we expect individual differences in the model’s parameters, as well as differences between HFASD and TD children, we use a hierarchical explanatory approach. A first analysis suggests that children with HFASD are less sensitive to the prototype. A second analysis, involving a mixture component, reveals that the computational model is not appropriate for a subgroup of participants, which implies parameter estimates are not informative for these children. Focusing only on the children for whom the prototype model is appropriate, no clear difference in sensitivity between HFASD and TD children is inferred. 相似文献

Today, thanks to biomedical technologies advances, some persons with fertility issues can conceive. Transgender persons benefit also from these advances and can not only actualize their self-identified sexual identities but also experience parenthood. Based on clinical multidisciplinary seminars that gathered child psychiatrists and psychoanalysts interested in the fields of assisted reproduction technology (ART) and gender dysphoria, philosophers interested in bioethics, biologists interested in ART, and endocrinologists interested in pubertal suppression, we explore how new biotechnical advances, whether in gender transition or procreation, could create new ways to conceive a child possible. After reviewing the various medical/surgical techniques for physical gender transition and the current ART options, we discuss how these new ways for persons to self-actualize and to experience parenthood can not only improve the condition of transgender persons (and the human condition as a whole through greater equity) but also introduce some elements of change in the habitual patterns of thinking especially in France. Finally, we discuss the ethical issues that accompany the arrival of these children and provide creative solutions to help society handle, accept, and support the advances made in this area. 相似文献

Inspired by Barsalou’s (Journal of Experimental Psychology: Learning, Memory, and Cognition, 11, 629–654, 1985) proposal that categories can be represented by ideals, we develop and test a computational model, the ideal dimension model
(IDM). The IDM is tested in its account of the typicality gradient for 11 superordinate natural language concepts and, using
Bayesian model evaluation, contrasted with a standard exemplar model and a central prototype model. The IDM is found to capture
typicality better than do the exemplar model and the central tendency prototype model, in terms of both goodness of fit and
generalizability. The present findings challenge the dominant view that exemplar representations are most successful and present
compelling evidence that superordinate natural language categories can be represented using an abstract summary, in the form
of ideal representations. Supplemental appendices for this article can be downloaded from . 相似文献

An account is given of the treatment of a pre-school child who had serious behavioural and physical handicaps. In a sense this is a study involving both psychotherapy and rehabilitation. The treatment consisted of applying laboratory-developed techniques through the attendants and the parents over a seven-month period. 相似文献

Narrative bioethics is primarily understood to involve storytelling through the use of literature. This article suggests that other forms of media are necessary to convey stories of an ethical nature to an audience broader than one being trained as medical professionals. "Documentary bioethics" is a manner to present and interpret stories of an ethical nature using forms of popular electronic media in a reality-based documentary style to society at large, specifically Generations X and Y. 相似文献

Sympathetic nervous system (SNS) activity at the time of acquisition is associated with human memory. However, rather than SNS activity per se, it may be afferent baroreflex feedback that is responsible for this effect. A pharmacological design was employed to unload (SNP, sodium nitro-prusside) and load (norepinephrine) baroreceptors. In addition to two placebo periods, epinephrine and esmolol (a peripherally acting beta1-blocker) served as control conditions for altered cardiac perception. During drug infusion blood pressure, heart rate, and perception of heartbeat were tested. Twenty-four healthy men were participated. The participants viewed emotional slides while their electromyographic eye blink responses to random noise bursts were measured (affective startle modulation paradigm) to determine potential drug impact on emotional processing. Subjects were not informed that memory testing would take place after 4 weeks. Drugs did not impact startle, thus indicating unbiased emotional processing at the time of acquisition. Norepinephrine had no effect on heartbeat perception, but improved (p = .002) recognition memory. SNP (p = .0001) increased heartbeat perception but impaired (p = .038) recognition memory. Epinephrine, on the other hand, increased heartbeat perception (p = .0001) yet did not impair but partially improve memory (effect on high arousing pictures only: p = .05). Heartbeat perception in the placebo condition did not correlate with recognition memory (p's > .5). We suggest that baroreflex unloading, with subsequent feedback activation of the SNS, impairs long-term incidental visual recognition memory in humans while baroreflex loading enhances it. Further, we propose that these memory effects are neither secondary to cardiac sensations that accompany SNS activation nor to altered emotional picture processing at the time of acquisition. 相似文献

McClelland's (Psychol. Rev. 86 (1979) 287) influential cascade model of reaction time (RT) is often seen as an important explicitly formulated alternative to strictly serial models because some of its basic notions fit in with known characteristics of neural activation processes. A disadvantage is that it is an essentially deterministic model to which noise is added by across-trials parameter variability that is unrelated to the concept of cascaded activation propagation per se. We propose and analyze a general stochastic cascade model based on neural counting processes; within this framework we present a new process-oriented interpretation of McClelland's cascade activation equation. We then theoretically explain and numerically explore conditions under which the stochastic cascade model predicts additive vs. interactive mean RT effects, and compare them to known properties of McClelland's model. Some of these properties remain valid even within a stochastic neural counting formulation, while others reflect assumptions which are essentially unrelated to the concept of cascaded activation. 相似文献

Characteristics of traditional Mexican-American families with consequent family rules that affect these family systems are discussed along with selected clinical cases. The specific cases discussed involve: (1) interactions with family of origin in intercultural marriages, (2) intracultural differences in levels of acculturation and traditional family rules, and (3) extended family impact in response to severe life crisis. The development of therapeutic processes from structural and strategic family therapy approaches, which reflect appreciation for cultural differences and strengths, is suggested.This material was presented at the annual meeting of the Texas Association for Marriage and Family Therapy, January, 1994, San Antonio, TX. 相似文献

Racemicd,l-lactate has long been used in burn therapy as Ringer’s lactate and in peritoneal dialysis fluid for treatment of renal failure. The d-lactate component of this racemic mixture is known to cause two forms of neurological toxicity in patients: encephalopathy and, in a subset of the population, panic reaction. Here we demonstrate that coma, similar in degree to that produced by blood levels of 75 mM ethanol was induced in rats by the intraperitoneal infusion of sodiumd-lactate sufficient to raise serumd-lactate concentration to 25 mM, whereas infusion of equal quantities of sodiuml-lactate produced no observable neurological effect. We further demonstrate that the intravenous infusion of racemicd,l-lactic acid into 48-hour fasted rats produced serious disturbances of cardiac rate and rhythm leading to death. When serumd-lactate concentration had reached 1–2 mM there was bradycardia, at 2–3 mM prolongation of QT interval, at 6–7 mM AV block with ectopic escape rhythms, and at 11 mM death in ventricular standstill or fibrillation. In contrast, intravenous infusion ofl-lactic acid to blood levels of 25 mM failed to produce any change in cardiac rhythm. On the other hand, the isolated working heart, free of influence from the central nervous system, displayed no change of cardiac rhythm or physiological function when perfused with 25 mM sodiumd,l-lactate. 相似文献
