We identify two biases in the traditional use of Bundesen’s Theory of Visual Attention (TVA) and show that they can be substantially reduced by introducing trial-by-trial variability in the model. We analyze whole and partial report data from a comprehensive empirical study with 347 participants and elaborate on Bayesian model selection theory for quantifying the advantage of trial-by-trial generalization in general. The analysis provides strong evidence of trial-by-trial variation in both the VSTM capacity parameter and perceptual threshold parameter of TVA. On average, the VSTM capacity bias was found to be at least half an item, while the perceptual threshold parameter was found to be underestimated by about 2 ms.  相似文献

Male aggressiveness is a complex behavior influenced by a number of genetic and non-genetic factors. Traditionally, the contribution of each of these factors has been established from experiments using artificially selected strains for high/low aggressive phenotypes. However, little is known about the factors underlying aggressive behavior in natural populations. In this study, we assess the influence of genetic background vs. postnatal maternal environment using a set of cross-fostering experiments between two wild-derived inbred strains, displaying high (STRA, derived from Mus musculus domesticus) and low (BUSNA, derived from Mus musculus musculus) levels of aggressiveness. The role of maternal environment was tested in males with the same genetic background (i.e. strain origin) reared under three different conditions: unfostered (weaned by mother), infostered (weaned by an unfamiliar dam from the same strain), and cross-fostered (weaned by a dam from a different strain). All males were tested against non-aggressive opponents from the A/J inbred strain. Resource-holding potential was assessed through body weight gains and territory ownership. The STRA males were shown to be aggressive in both neutral cage and resident-intruder tests. On the contrary, the BUSNA males were less aggressive in all tests. We did not find a significant effect of postnatal maternal environment; however, we detected significant maternal effect on body weight with differences between the strains, fostering type and interactions between these factors. We conclude that the aggressiveness preserved in the two strains has significant genetic component whose genetic basis can be dissected by quantitative trait loci analysis.  相似文献

Through the criminal justice system so-called dangerous offenders are, besides the offence that they are being convicted of and sentenced to, also punished for acts that they have not done but that they are believe to be likely to commit in the future. The aim of this paper is to critically discuss whether some adherents of retributivism give a plausible rationale for punishing offenders more harshly if they, all else being equal, by means of predictions are believed to be more dangerous than other offenders. While consequentialism has no problem, at least in principle, with this use of predictions most retributivists have been opponents of punishing offenders on the basis of predictions. How can an offender deserve to be punished for something that he has not done? But some retributivists like Anthony Duff and Stephen Morse have argued in favor of punishing offenders who are considered to be dangerous in the future more harshly than non-dangerous offenders. After having reconstructed their arguments in detail, it will be argued that both Duff’s and Morse’s attempts to give a retributivistic justification have several shortcomings.  相似文献

The article considers the potential of intergenerational encounters and family and social ties for alleviating loneliness and promoting older adults’ wellbeing. Loneliness has been widely recognized as one of the factors that are most deeply and pervasively detrimental to older adults’ wellbeing. We combine theoretical reflections with a comparative study of older adults in Denmark and China. Both countries have to deal with an aging population and growing number of cases of isolation and loneliness in an increasingly individualized society. They differ, however, with regard to how far they have developed a system of institutionalized care, as well as with regard to their culture-specific views of family life and parent-child relationships. We apply the notions of filial piety, known from Confucian philosophy but often misinterpreted as conservative and conformist, and generativity, to qualitative studies of older adults in Denmark and China. The great potential of intergenerational ties is confirmed. Our study also shows that filial piety is still highly valued, in both China and Denmark, and can be maintained even in a highly individualized society. There is, however, considerable uncertainty among both older adults and their younger relatives as to what is required and what can be expected; realism, and an emphasis on the quality, rather than the quantity of interaction, may be sensible coping strategies, but can also lead to unnecessary acquiescence and self-abnegation. Our study also serves to distinguish different aspects and effects on wellbeing of intergenerational relationships.

Starting from a general definition of pastoral care and politics, it is argued that pastoral care can have nothing to do with party politics. Instead, the theme of pastoral care and politics should be regarded as a sub-set of the larger issue of religion and politics in a democratic society. Adopting the view that political philosophy is at bottom an exercise in moral reflection, this article focuses on two interrelated issues: the compatibility of religion and democracy, and the connection between religion and morality. The argument proceeds in three steps. In the first section, it is demonstrated why and how major political philosophers deem it necessary to impose certain limitations on the role of religion in the public square. In the second section, Kierkegaard’s interpretation of the biblical story of Abraham’s near-sacrifice of Isaac (Gen. 22) is treated as a problematic tradition in Christian theology of admiring authoritarian faith. Finally, as a means of overcoming these difficulties, a plea is made for returning to the tradition of liberal theology and its emphasis on the internal connection between religion and morality, and on developing conscience and civic virtues by way of self-culture.  相似文献

Individual health counseling is a form of intervention designed to minimize the effects of chronic health disease and to offer a path towards good health practices. The aim of the present study was to explore the experiences of those persons who participated in health counseling in order to assess the psychosocial significance of the counseling upon their health behavior. In addition the study was concerned with the factors which underlay peoples' decision to sign up for health counseling. The research involved 11 semi‐structured interviews with individuals who had participated in a municipality based health counseling program. Data was analyzed using Malterud's systemic text condensation and a theoretical framework around Bandura's social cognitive theory. Analysis revealed that an approach tailored to each individual with minor short‐term goals accompanied by feeling supported by the counselor produced the greatest impact on behavior. Receiving feedback from the counselor and feeling positive about the relationship were seen as essential. These aspects were also crucial in the decision to undertake health counseling. The study indicates that whether individual's sign up on their own initiative or conversely are invited to join the program has no influence upon their motivation to change their behavior. Overall the respondents demonstrated improvement in their behavior and attitudes towards their health. However, the study also indicates that this form of intervention is less or even ineffective without the support of the individual's immediate family.  相似文献

Recent studies indicate that divorce sometimes is positive for subjective well-being, but we lack knowledge about the circumstances under which this is the case. Further, we lack knowledge about the possible different associations between divorce and life satisfaction (LS) vs. positive affect (PA). The current study is based on the Norwegian Mother and Child Cohort Study (MoBa). Change in LS and PA over a three-year period was examined in women who divorced and women who did not divorce (N > 37,000). Relationship quality and relationship status at follow-up were included in the models. The results indicated that divorce predicted higher LS and PA when initial relationship quality was poor. Furthermore, divorce predicted higher PA for women who, after divorce, reported being in a new romantic relationship. The associations between relationship quality and LS and PA were stronger among not-divorced than divorced women, indicating that relationship quality affects LS and PA.  相似文献
