There is substantial evidence that psychological factors influence human testosterone levels, but little support if any for an influence of circulating testosterone on dominance in men. Persistent interest in testosterone as an explanation of behaviors such as dominance and aggression might reflect the influence of cognitive schemas regarding race and sex rather than empirical evidence.

A recent critique of hierarchical Bayesian models of delusion argues that, contrary to a key assumption of these models, belief formation in the healthy (i.e., neurotypical) mind is manifestly non-Bayesian. Here we provide a deeper examination of the empirical evidence underlying this critique. We argue that this evidence does not convincingly refute the assumption that belief formation in the neurotypical mind approximates Bayesian inference. Our argument rests on two key points. First, evidence that purports to reveal the most damning violation of Bayesian updating in human belief formation is counterweighted by substantial evidence that indicates such violations are the rare exception—not a common occurrence. Second, the remaining evidence does not demonstrate convincing violations of Bayesian inference in human belief updating; primarily because this evidence derives from study designs that produce results that are not obviously inconsistent with Bayesian principles.

In this chapter, two aspects of the meaningful work context are considered: task discretion and organizational participation. It argues that these provide opportunities for values associated with meaningful work to be realized at both an intrinsic and instrumental level. Drawing on both theoretical arguments and empirical evidence, the chapter explores the extent to which meaningful work values are realized in both domains. Two types of direct participation are found to be complementary: task discretion is particularly important for increasing the scope for informal learning, while organizational participation is a stronger lever for securing higher levels of training provision. The chapter presents substantial evidence that participation in decision-making, both at the level of the work task and in wider organizational decisions, is an essential precondition of meaningful work.

Abstract This paper argues that the “necessity of protection” should be seriously considered when evaluating the effect of misrepresentation, but a substantial criterion or a formal standard with rebuttable and substantial exception is recommended. The weakness of insured is a key characteristic in insurance law. This feature leads to the typical idea that the insured should deserve more protection in insurance contract. However, the necessity of protection may vary in different types of insurance and occasions. Thus, many jurisdictions use consumer or business insurance, sophisticated or unsophisticated insured and similar standard to differentiate the levels of protection for insured. For misrepresentation, one of the most important issue in insurance law, many jurisdictions also use this criterion in designing misrepresentation’s elements and consequences. This paper aims to find justification for this standard theoretically and empirically for Taiwan. The paper starts with the general discussion for distinguishing consumer insurance and business insurance. Then, the focus will be moved on to misrepresentation, especially about the distinction between consumer insurance and business insurance, and its effect on misrepresentation’s elements and consequences. Afterwards, this paper argues the inefficiency of the bright-rule for evaluating the necessity of protection and the distinction between business insurance and consumer insurance. Empirical evidence is also provided to assess the effects of elements in Taiwan. Finally, the study proposes that a substantial criterion or a bright-line rule which can be rebutted by substantial evidence may be a more proper and efficient model.

Political consumerism is currently one of the most prevalent forms of non-institutionalized political engagement in Western democracies. This article aims to understand its psychological roots. We expect interindividual differences in psychological dispositions to be particularly relevant for political consumerism due to the individualized and cause-oriented nature of this form of political action. Our empirical evidence supports this claim: Open people favour, and conscientious people avoid, boycotting and buycotting. Agreeable persons tend to avoid boycotting in particular. These relationships persist even when political and social attitudes are controlled for. Thus, we show that psychological factors play an important role in shaping politically conscious consumption behaviour. At the same time, our study points out that personality profiles vary across different forms of political consumerism and modes of political action more generally. The characteristics of the diverse modes may help to understand this variation.

Abstract The arguments offered by Jaswal & Akhtar to counter the social motivation theory (SMT) do not appear to be directly related to the SMT tenets and predictions, seem to not be empirically testable, and are inconsistent with empirical evidence. To evaluate the merits and shortcomings of the SMT and identify scientifically testable alternatives, advances are needed on the conceptualization and operationalization of social motivation across diagnostic boundaries.

Abstract The integration of first-, second-, and third-personal information within joint intentional collaboration provides the foundation for broad-based second-personal morality. We offer two additions to this framework: a description of the developmental process through which second-personal competence emerges from early triadic interactions, and empirical evidence that collaboration with a concrete goal may provide an essential focal point for this integrative process.

Although a previous study in this laboratory determined that Purkinje cells of the rat cerebellum did not appear to be damaged following 30 min of forebrain ischemia followed by 30 min of reperfusion, it was suggested that an increase in rough endoplasmic reticulum (RER) and/or polysomes had occurred in these cells. The primary objective of the present study was to morphometrically determine whether or not this increase had occurred. In addition, since there is substantial evidence that glial cells may be affected by ischemia earlier than other cell types, glial cells also were examined. To ascertain possible effects on other cerebellar components, granule cells and neuropil near Purkinje cells as well as neuropil in the molecular layer also were evaluated in this investigation.
