Against the backdrop of critical clinical blood shortage in China in recent years, the present research extends the theory of planned behaviour by incorporating two constructs potentially of importance in influencing non‐remunerated blood donation behaviour, namely perceived risk and individual trust in blood collection agencies to predict Chinese people's non‐remunerated blood donation intention and behaviour. A survey was conducted to measure variables of the theory of planned behaviour, and other variables such as experience of non‐remunerated blood donation, perceived risk and individual trust in blood collection agencies. Data to assess non‐remunerated blood donation behaviour were collected via phone interviews. Results of the path analysis are as follows. Subjective norm, perceived behavioural control and individual trust in blood collection agencies are all positively associated with attitudes toward non‐remunerated blood donation, explaining 46.9% of the variance in this variable. Perceived risk is negatively associated with blood donation intention, while subjective norm and attitudes toward non‐remunerated blood donation are both positively associated with blood donation intention. Together, the three variables account for 28.4% of the variance in donation intention. Both having a positive association with non‐remunerated blood donation behaviour, the combination of blood donation intention and donation experience explains 42.8% of its variance.  相似文献

The paper explores the relationship between attachment to God (AG) and authenticity/inauthenticity among Christian youths in relation to a range of socio-demographic variables. Cross-sectional data were collected from 100 South African Christian youths using measures of AG and authenticity/inauthenticity. The correlation results reveal that feelings of insecurity in terms of having anxiety in a relationship with God is positively related to self-alienation (feeling out of touch with oneself) and accepting external influences (conforming to the standards and expectations of others), but negatively correlated to authentic living (being in tune with one’s self). Feelings of insecurity in terms of avoidant God-attachment was also related to self-alienation. In addition, demographic differences were observed for gender and church denomination. These results suggest that insecurity with God may either be linked to feelings of authenticity or self-estrangement among Christian youths and have broad implications, both for clinical usage and further cross-cultural research.  相似文献

Behavioral dysexecutive disorders are highly prevalent in patients with neurological diseases but cannot be explained by cognitive dysexecutive impairments. In fact, the underlying mechanisms are poorly understood. Given that socioemotional functioning underlies appropriate behavior, socioemotional impairments may contribute to the appearance of behavioral disorders. To investigate this issue, we performed a transnosological study.

Seventy-five patients suffering from various neurological diseases (Alzheimer’s disease (AD), Parkinson’s disease (PD), frontotemporal lobar degeneration, and stroke) were included in the study. The patients were comprehensively assessed in terms of cognitive and behavioral dysexecutive disorders and socioemotional processes (facial emotion recognition and theory of mind). As was seen for cognitive and behavioral dysexecutive impairments, the prevalence of socioemotional impairments varied according to the diagnosis. Stepwise logistic regressions showed that (i) only cognitive executive indices predicted hypoactivity with apathy/abulia, (ii) theory of mind impairments predicted hyperactivity–distractibility–impulsivity and stereotyped/perseverative behaviors, and (iii) impaired facial emotion recognition predicted social behavior disorders. Several dysexecutive behavioral disorders are associated with an underlying impairment in socioemotional processes but not with cognitive indices of executive functioning (except for apathy). These results strongly suggest that some dysexecutive behavioral disorders are the outward signs of an underlying impairment in socioemotional processes.  相似文献

Planning and decision-making are two of the cognitive functions involved in the solution of problems. These functions, among others, have been studied from the point of view of a new field known as cognitive informatics focused on the development of cognitive architectures, autonomous agents, and human robots that are capable of showing human-like behavior. We present an exhaustive study of current biological and computational models proposed in the fields of neuroscience, psychology, and cognitive informatics. Also, we present a deep review of the brain areas involved in planning, decision-making, and affection. However, the majority of the proposed computational models are seeking to mimic human external behavior. This paper aims to contribute to the cognitive informatics field with an innovative cognitive computational model of planning and decision-making. The two main differences of our model with respect to the current models in the literature are: (i) our model considers affective and motivational information as a basic and essential trigger in planning and decision-making processes; (ii) our model attempts to mimic both the internal human brain as well as the external human behavior. We developed a computational model capable of offering a direct mapping from human brain areas to computational modules of our model. Thus, in this paper we present our model from a conceptual, formal, and computational approach in order to show how our proposal must be implemented. Finally, a set of tests were conducted in order to validate our proposal. These tests show an interesting comparison between the behavior of our prototype and the behavior exhibited by some people involved in a case study.  相似文献

Proponents of cognitive Situationism argue that the human mind is embodied, embedded in both natural and social-cultural environments and extended creating both extended and distributed cognition. Anti-situationists reject all or some of these claims. I argue that four major objections to extended cognition: (1) the mark of the cognitive, (2) the function-identity fallacy, (3) cognitive bloat, and (4) scientific irrelevance lose much of their sting in the case of distributed cognition, the extension of cognitive agency to a group of cognitive agents, such as a scientific research team. However, I claim that a crucial fifth challenge, that advocates of the extended mind commit the causal-constitution fallacy, has yet to be satisfactorily addressed. I focus on Spyridon Palermos’ use of dynamic systems theory to refute this charge and I argue that his appeal to dynamic systems theory as a way of understanding system-constitution fails. Instead, I suggest a social-cultural group selection hypothesis for understanding system-constitution. But, I leave it for another day to elaborate that hypothesis’ empirical plausibility.  相似文献

Rehabilitation within three months plays a significant role in the recovery of damaged motor functions following the onset of a stroke. To increase the effectiveness of rehabilitation, it is important to perform rehabilitative exercises with movement intention. This study analyzed the association between electroencephalogram (EEG) and electromyogram (EMG) signals in healthy individuals in an attempt to verify the differences between the two signals in corticomuscular connectivity as well as the time delay in the flow of information in accordance with the presence of movement intention. To examine the relationship between the brain and muscles, coherence and mutual information analyses were performed on the EEG signals in the motor cortex and EMG signals in the flexor digitorum superficialis muscle during grasping training. Coherence and mutual information between EEG and EMG signals were significantly higher and the time delay of information flow was shorter when subjects performed active exercise with movement intention than when they performed passive exercise without movement intention. These findings could be applied to the rehabilitation of stroke patients to develop a rehabilitative training system with heightened effectiveness through verification of the presence of movement intention in the patients.  相似文献

ObjectivesPerfectionistic strivings (PS) and perfectionistic concerns (PC) have shown different profiles with the 2 × 2 achievement goals in sport. Whether PS and PC also show comparable profiles with the achievement goals of the expanded 3 × 2 framework, however, is unclear.DesignCross-sectional.MethodWe examined self-reported perfectionistic strivings, perfectionistic concerns, and the 3 × 2 achievement goals in 136 junior athletes (mean age 17.0 years).ResultsThe results of structural equation modeling showed that PS were positively associated with task-, self-, and other-approach goals and negatively with task- and self-avoidance goals. In contrast, PC were positively associated with task-, self-, and other-avoidance goals and negatively with task- and self-approach goals.ConclusionsThe findings suggest that PS and PC show different profiles also with the 3 × 2 achievement goals which may help explain why the two perfectionism dimensions show differential relations with achievement-related outcomes in sport.  相似文献

Greater support is required in health promotion for practitioners to adopt critical approaches to their practice. Despite recognition of the role that critical reflection can play in supporting critical practice, it is underdeveloped in health promotion. This pilot study aimed to explore the use of critical reflection with health promotion practitioners. Critical postmodernism provided the theoretical perspective and critical reflection methodology guided the study. The data collection method involved the application of a critical reflection model via in-depth semi-structured interviews with two health promotion practitioners who were recruited using purposive sampling. Critical postmodernism and critical health promotion values and principles were the thematic frameworks used to analyse the data. Four types of assumptions were identified across both participants’ narratives: binary opposites and dichotomous thinking; identity and othering; professionalism; and power. Two key themes that evidenced these assumptions were conceptualising power as a commodity, and identity in the Aboriginal and Torres Strait Islander context. Both traditional and critical health promotion practice approaches were evident in participants’ practice. The process of engaging in critical reflection resulted in positive outcomes for the practitioners, including the identification of new, more critical ways of practising. Critical reflection provides a process for developing critical health promotion practice. The designation of critical reflection as a core health promotion competency may enhance the development of critical health promotion. Further research is needed to develop and test a critical reflection model incorporating the values and principles of health promotion with a larger sample of practitioners.  相似文献

Natural scientists increasingly employ the notion of system, i.e. organized groups of individual entities in dynamic interrelation, as a controlling metaphor in their analysis of physical reality, thereby reflecting a new emphasis on ecology and a holistic approach to reality. A.N. Whitehead’s understanding of the reciprocal cause-and-effect relation between constituent actual entities and the governing structure of the “society” to which they belong provides philosophical grounding for this new methodology and removes the danger of regarding systems as completely deterministic rather than open-ended and self-organizing. Likewise, a systems-oriented approach to the Christian doctrines of the Trinity, the Incarnation and Eschatology clears up residual ambiguities in the traditional understanding of those same beliefs.  相似文献
