In recent years, there has been increasing interest in studying listening effort. Research on listening effort intersects with the development of active theories of speech perception and contributes to the broader endeavor of understanding speech perception within the context of neuroscientific theories of perception, attention, and effort. Due to the multidisciplinary nature of the problem, researchers vary widely in their precise conceptualization of the catch-all term listening effort. Very recent consensus work stresses the relationship between listening effort and the allocation of cognitive resources, providing a conceptual link to current cognitive neuropsychological theories associating effort with the allocation of selective attention. By linking listening effort to attentional effort, we enable the application of a taxonomy of external and internal attention to the characterization of effortful listening. More specifically, we use a vectorial model to decompose the demand causing listening effort into its mutually orthogonal external and internal components and map the relationship between demanded and exerted effort by means of a resource-limiting term that can represent the influence of motivation as well as vigilance and arousal. Due to its quantitative nature and easy graphical interpretation, this model can be applied to a broad range of problems dealing with listening effort. As such, we conclude that the model provides a good starting point for further research on effortful listening within a more differentiated neuropsychological framework. 相似文献

Change point detection in multivariate time series is a complex task since next to the mean, the correlation structure of the monitored variables may also alter when change occurs. DeCon was recently developed to detect such changes in mean and\or correlation by combining a moving windows approach and robust PCA. However, in the literature, several other methods have been proposed that employ other non-parametric tools: E-divisive, Multirank, and KCP. Since these methods use different statistical approaches, two issues need to be tackled. First, applied researchers may find it hard to appraise the differences between the methods. Second, a direct comparison of the relative performance of all these methods for capturing change points signaling correlation changes is still lacking. Therefore, we present the basic principles behind DeCon, E-divisive, Multirank, and KCP and the corresponding algorithms, to make them more accessible to readers. We further compared their performance through extensive simulations using the settings of Bulteel et al. (Biological Psychology, 98 (1), 29-42, 2014) implying changes in mean and in correlation structure and those of Matteson and James (Journal of the American Statistical Association, 109 (505), 334-345, 2014) implying different numbers of (noise) variables. KCP emerged as the best method in almost all settings. However, in case of more than two noise variables, only DeCon performed adequately in detecting correlation changes. 相似文献

Data provided by 150 9- to 11-yr.-old primary school pupils in England showed scores on the Francis Scale of Attitude toward Christianity more highly correlated with (personal) prayer (r = .57) than with (public) church attendance (r = .23), providing support for the view that attitude scales access a deeper level of religiosity less contaminated by those contextual and social factors which may influence public church attendance more than personal prayer. 相似文献

How do people react to those who have helped them? The authors propose that a recipient's evaluation of a helper's intentions and the recipient's own attitudes about future interactions with the helper depend partly on the recipient's perceptions of how the helper decided to assist: on the basis of affect, of role, or of cost-benefit calculation. When a recipient perceives that the decision was based on affect (i.e., positive feelings about him or her), he or she will be more inclined toward future interaction and reciprocation than if he or she perceives the decision as based on role or cost-benefit calculation. It is proposed that these "decision modes" signal the helper's underlying attitudes about the recipient, which in turn, clarify their relationship. A boundary is also identified: The negative impact of apparent cost-benefit thinking is greatest when the amount of help provided is small. Predictions are confirmed in four studies of actual and experimentally manipulated helping episodes. 相似文献

The authors examined whether individuals' approaches to relationships, expressed in terms of attachment styles, was related to how they viewed ideal leadership and to their degree of tendency to emerge as team leaders. Specifically, the authors hypothesized that attachment styles, or cognitive representations of orientation to others, would explain individual differences in leadership perceptions and emergence. Participants were 127 American students in college teams. The authors found that securely attached individuals (n = 81) perceived themselves as more effective team members than did insecurely attached individuals (n = 46) and that fellow team members saw securely attached team members as emerging team leaders significantly more often than they did insecurely attached team members. 相似文献

A sample of 158 churchgoers attending eight Anglican churches in the United Kingdom completed the abbreviated Revised Eysenck Personality Questionnaire together with the Francis Scale of Attitude toward Christianity to replicate a 1996 study by Carter, Kay, and Francis. Data confirm that scores on Attitude toward Christianity were significantly negatively related to Psychoticism, but to neither Extraversion nor Neuroticism scores. 相似文献

This paper discusses the general problem of translation functions between logics, given in axiomatic form, and in particular, the problem of determining when two such logics are synonymous or translationally equivalent. We discuss a proposed formal definition of translational equivalence, show why it is reasonable, and also discuss its relation to earlier definitions in the literature. We also give a simple criterion for showing that two modal logics are not translationally equivalent, and apply this to well-known examples. Some philosophical morals are drawn concerning the possibility of having two logical systems that are empirically distinct but are both translationally equivalent to a common logic. 相似文献

This study of older patients with osteoarthritis and their spouses examined concordance between patients' and spouses' reports of patients' pain severity and the association of concordance with support and caregiving outcomes. Patients and spouses independently viewed videotapes of the patient performing simulated household tasks and provided ratings of patients' pain. Spousal overestimation of patients' pain was the most common type of nonconcordance. Spouses who were accurate in their perceptions of their partner's level of pain during a log-carrying task responded less negatively and provided emotional support that was more satisfying to patients. In addition, spouses who were accurate in their perceptions of their partner's pain during the log-carrying task reported less stress from providing support and assistance. Future research that uses such observational methods may be highly useful for understanding the effects of chronic illness on older couples. 相似文献

Neurotrophins, such as brain-derived neurotrophic factor (BDNF), are a unique family of polypeptide growth factors that influence
differentiation and survival of neurons in the developing nervous system. In adults, BDNF is important in regulating synaptic
plasticity and connectivity in the brain. Recently, a common single-nucleotide polymorphism in the human BDNF gene, resulting
in a valine to methionine substitution in the prodomain (Val66Met), has been shown to lead to memory impairment and susceptibility
to neuropsychiatric disorders. An understanding of how this naturally occurring polymorphism affects behavior, anatomy, and
cognition in adults is an important first step in linking genetic alterations in the neurotrophin system to definable biological
outcomes in humans. We review the recent literature linking this BDNF polymorphism to cognitive impairment in the context
of in vitro and transgenic animal studies that have established BDNF’s central role in neuronal functioning in the adult brain. 相似文献
