A sample of 2145 adults completed the Personal Globe Inventory (PGI) as well as indicating their occupational choice and the certainty of this choice. The PGI yielded interest and self-efficacy scores and these were used with the occupational choice to calculate a congruence score for interests and one for efficacy. The prediction of career certainty by each congruence measure and their interaction was examined using hierarchical regression. The results indicated that while both interest and efficacy congruence were related to career certainty, efficacy congruence did not add to prediction above that obtained using interests congruence alone, however there was a substantial interaction. The agreement of interest congruence and efficacy congruence was related to a strong positive relation between congruence and certainty; whereas low agreement between interest and efficacy congruence was related to a non-significant relation between congruence and certainty. The results demonstrate the need to focus on both interest and efficacy and their agreement in our assessments and interventions.  相似文献

Countertransference is a concept that is widely acknowledged, but there exists little definitional consensus, making research in the area difficult. The authors adopted a prototype theory (E. H. Rosch, 1973a, 1973b; see C. B. Mervis & E. Rosch, 1981, for a review) to examine this construct because it conceptually fits well with constructs that elude explicit definition. In Study 1, 45 experienced psychologists highly agreed with the prototypicality of 104 different examples of countertransference providing support for the presence of a prototype. In Study 2, the usage of this prototype in a sample of 35 trainees was related to ability to perceive countertransference in a case example drawn from the literature and positively correlated with self-reports of their experiences of countertransference but not with their self-reported ability to manage countertransference once it was manifest. Implications for training and research are discussed.  相似文献

The purpose of this study was to explore athletes' experiences with doping education and their recommendations to improve current education to create more effective doping prevention interventions. Following a constructivist approach, interviews were conducted with 21 athletes and analyzed inductively with thematic analysis. Six themes were identified relating to athletes' experiences with doping education and recommendations for improving it. Athletes commonly described receiving insufficient doping education during adolescence, highlighting the need for increased doping prevention efforts. Recommendations for future educational programs include addressing doping prevention collaboratively, implementing education at younger ages, and assuring the programs are engaging and interactive.  相似文献

In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms of which represent physical processes. Usually, this category is taken to be at least compact closed, and more often, dagger compact, enforcing a certain self-duality, whereby preparation processes (roughly, states) are interconvertible with processes of registration (roughly, measurement outcomes). This is in contrast to the more concrete “operational” approach, in which the states and measurement outcomes associated with a physical system are represented in terms of what we here call a convex operational model: a certain dual pair of ordered linear spaces–generally, not isomorphic to one another. On the other hand, state spaces for which there is such an isomorphism, which we term weakly self-dual, play an important role in reconstructions of various quantum-information theoretic protocols, including teleportation and ensemble steering. In this paper, we characterize compact closure of symmetric monoidal categories of convex operational models in two ways: as a statement about the existence of teleportation protocols, and as the principle that every process allowed by that theory can be realized as an instance of a remote evaluation protocol—hence, as a form of classical probabilistic conditioning. In a large class of cases, which includes both the classical and quantum cases, the relevant compact closed categories are degenerate, in the weak sense that every object is its own dual. We characterize the dagger-compactness of such a category (with respect to the natural adjoint) in terms of the existence, for each system, of a symmetric bipartite state, the associated conditioning map of which is an isomorphism.  相似文献

RESUMEN

En una amplia variedad de tareas de detección de objetivos auditivos y visuales, la ejecución era escasamente influida por el número de no-objetivos simultáneos, pero le afectaba si los objetivos simultáneos debían ser detectados por separado. Se ha sugerido que sólo los objetivos necesitan pasar por un sistema de capacidad limitada que conduce a la conciencia; los no-objetivos pueden ser identificados y rechazados por un procesamiento paralelo e inconsciente. Puesto que las palabras no- objetivo, por ejemplo, se pueden rechazar en base al significado, el estímulo debe ser completamente analizado antes de pasar por el sistema de capacidad limitada. De modo general, la disminución en la ejecución debida a la atención dividida es acusada siempre que la estimulación simultánea (psicofísica, verbal, etc.) se deba identificar por separado, puesto que bajo estas circunstancias cualquier estimulación debe pasar por un sistema de capacidad limitada hasta la conciencia.  相似文献

Promoting the ability to reason generatively about novel phenomena and problems students may encounter in their everyday lives is a major goal of science education. This goal proves to be a formidable challenge in domains, such as molecular genetics, for which the accumulated scientific understandings are daunting in both amount and complexity. To develop effective instruction that fosters generative reasoning we need to have a sound understanding of the types of knowledge in the domain that are critical for such reasoning. In this study I examined the ensemble of knowledge, both general and domain-specific, undergraduate students employed in reasoning about problems in genetics. I found that students initially formulate a solution in terms that are not domain specific and that serve as a frame–solution frame–that outlines and constrains a more specific and domain-appropriate explanation. This solution frame is then filled in with two powerful forms of domain-specific knowledge I term: domain-specific heuristics and domain-specific explanatory schemas. These knowledge forms embody understandings of central mechanisms and entities in molecular genetics. By invoking these domain-specific knowledge forms, students were able to reason about a variety of both familiar and novel genetics problems. I present a cognitive model that highlights the role of these powerful conceptual understandings in promoting generative reasoning in genetics.  相似文献

The present study aims to identify whether individuals’ with a fear of being laughed at (gelotophobia), respond with less facially displayed joy (Duchenne display) generally towards enjoyable emotions or only those eliciting laughter. Forty participants (no vs. gelotophobia) described their feelings to scenarios prototypical for the 16 enjoyable emotions proposed by Ekman (Emotions revealed: recognizing faces and feelings to improve communication and emotional life. Times Books, New York, 2003), while being unobtrusively filmed. Facial responses were coded using the Facial Action Coding System (FACS, Ekman et al. in Facial Action Coding System: a technique for the measurement of facial movement. Consulting Psychologists Press, Palo Alto, 2002). The gelotophobes showed less facial expression of joy compared to the non-gelotophobes (Hypothesis 1) and this effect was stronger for frequency and intensity of Duchenne displays towards laughter-eliciting enjoyable emotions than for no laughter-eliciting enjoyable emotions (Hypothesis 2). Moreover, the no gelotophobia group responded more strongly to laughter-eliciting than to no laughter-eliciting enjoyable emotions. Individuals with marked gelotophobia showed the reverse pattern, displaying less joy in laughter-eliciting emotions which may impact on their social interaction, as communication may break down when positive emotion are not reciprocated.  相似文献

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.  相似文献

Abstract

Increasing evidence suggests that regular physical activity can have considerable psychological, as well as physical, benefits in the elderly. Although factors such as exercise dosage may be implicated in exercise-induced affect responses, it has also been suggested that social and psychological factors might influence this relationship. This study examined the roles played by exercise environment (group versus alone) and self-efficacy in affective change in 80 older adults (M age = 66 yrs) over the course of three acute exercise bouts. Using latent growth curve methodology and statistically controlling for duration and intensity of exercise, we were able to demonstrate that social (group) environments resulted in statistically significant improvements in feeling state responses when contrasted with a condition in which the participants exercised alone. In addition, increases in self-efficacy were associated with more positive and less negative feeling states. Environmental factors that might influence the exercise-affect response are discussed and recommendations for subsequent exercise, efficacy, affect research made.  相似文献
