The proper evaluation of a theory’s virtues seems to require taking into account what the theory is indirectly or implicitly committed to, in addition to what it explicitly says. Most extant proposals for criteria of theory choice in the literature spell out the relevant notion of implicit commitment via some notion of entailment. I show that such criteria behave implausibly in application to theories that differ over matters of entailment. A recent defence by Howard Peacock of such a criterion against this objection is examined and rejected. I go on to a develop a better proposal on which, roughly speaking, a theory is counted committed to a claim if and only if its best fully explicit extension is explicitly committed to the claim. Such extensions in turn are evaluated by ordinary standards of theory choice adapted to the case of theories assumed to articulate their intended content in a fully explicit fashion.  相似文献

Choice blindness is the finding that participants both often fail to notice mismatches between their decisions and the outcome of their choice and, in addition, endorse the opposite of their chosen alternative. But do these preference reversals also carry over to future choices and ratings? To investigate this question, we gave participants the task of choosing which of a pair of faces they found most attractive. Unknown to them, we sometimes used a card trick to exchange one face for the other. Both decision theory and common sense strongly suggest that most people would easily notice such a radical change in the outcome of a choice. But that was not the case: no more than a third of the exchanges were detected by the participants. We also included a second round of choices using the same face pairs, and two stages of post‐choice attractiveness ratings of the faces. This way we were able to measure preference strength both as choice consistency and by looking at measures of rating differences between chosen and rejected options. We found that the initially rejected faces were chosen more frequently in the second choice, and the perceived attractiveness of these faces was increased even in uncoupled individual ratings at the end of the experiment. This result is discussed in relation to Chen and Risen's recent criticism of the Free Choice Paradigm, as it shows that choices can affect future preferences.

Most psychotherapists and researchers agree that a good relationship essentially contributes to therapeutic change. The psychoanalytic concepts transference and countertransference which describe fundamental aspects of the psychotherapeutic relationship have now become integrated into behavior therapy. These concepts, however, are used differently in psychoanalysis as well as in behavior therapy. This makes the communication between psychotherapists coming from different orientations difficult. Therefore, a research approach which describes the important verbal and nonverbal elements of a helpful therapeutic interaction independently from therapeutic orientation could help to evaluate their effectiveness in different psychotherapeutic methods. In this way a culture of integration into psychotherapy could be encouraged.  相似文献

Background

Despite changes in the regulations concerning outpatient psychotherapy in Germany, relatively few patients with substance use disorders receive this type of treatment.

Objectives

The results of a recent study among stimulant users are taken as an example to illustrate the psychotherapeutic needs of patients with substance use disorders.

Materials and methods

A total of 392 individuals with active use of amphetamine and/or methamphetamine were included using a broad range of recruitment strategies. In a mixed methods approach, qualitative as well as quantitative data were gathered regarding the history of substance use, the motives for use, and traumatic experiences during childhood.

Results

Psychological distress was a frequent motive even at the initiation of stimulant use. About two thirds of the participants (65.1?%) reported at least one form of childhood trauma (sexual, physical or emotional abuse, emotional or physical neglect).

Conclusion

The findings suggest a high need for psychotherapy among patients with substance use disorders. It seems important to further improve the information as well as the training of psychotherapists to work with these clients.  相似文献

At workplaces where nanomaterials are produced or used, risk assessment and risk management are extremely difficult tasks since there is still limited evidence about the risks of nanomaterials. Measurement methods for nanoparticles are contested and safety standards have not yet been developed properly. To support compliance with the legal obligation of the employer to care for safe workplaces a large number of ‘soft’ regulatory tools have been proposed (e.g. codes of conduct, benchmarks, standards). However, it is not clear whether and under which conditions soft regulation is complied with. This article discusses the potential advantages and drawbacks of soft regulation. It explores compliance issues when exposure measurement devices and other technology-related factors are involved. The exploration of three examples of soft regulation on occupational health and safety (a ministerial recommendation on preliminary exposure benchmarks, a nano-specific guidance of a chemical company and a public–private OHS guideline) shows that the capacity of the regulated parties to comply depends on the availability of appropriate technological devices and methods, technical expertise and other resources. When technological prerequisites are met, compliance is likely to increase.  相似文献

This paper focuses on the contribution of meta-regulation in responding to the regulatory needs of a field beset by significant uncertainties concerning risks, benefits and development trajectories and characterised by fast development. Meta-regulation allows regulators to address problems when they lack the resources or information needed to develop sound “discretion-limiting rules”; meta-regulators exploit the information advantages of those actors to be regulated by leveraging them into the task of regulating itself. The contribution of meta-regulation to the governance of nanotechnologies is assessed in terms of responsibilisation. Responsibilisation is regarded as a pre -requisite for regulatory actors to internalise social values (such as consumer safety and occupational health) and to ensure that these values are built into regulatory practice. In order to explore the potential of responsibilisation, the Code of Conduct for Responsible Nanosciences and Nanotechnologies Research launched by the European Commission in 2008 is evaluated. The Code is a good case of meta-regulation that aims to steer the self-regulation of nanotechnological business and research organisations. The paper concludes that, while efforts were made on the part of meta-regulators and self-regulators to contribute to responsibilisation, important opportunities for responsibilisation such as dissemination and promotion of the Code, trust-building activities, and failure to provide rewards, incentives and stakeholder guidance were not taken up. In order to foster responsibilisation within the meta-regulatory instrument of the EC Code, a number of crucial activities to be undertaken by meta-regulators are recommended.  相似文献

The Quick-Estimation heuristic (QuickEst) was introduced by Hertwig, Hoffrage, and Martignon (1999 Hertwig , R. , Hoffrage , U. , & Martignon , L. (1999) . Quick estimation: Letting the environment do the work . In G. Gigerenzer , P. M. Todd , & the ABC Research Group (Eds.) , Simple heuristics that make us smart (pp. 209234) . New York : Oxford University Press . [Google Scholar]) as a fast and frugal method to generate numerical estimates. The heuristic posits that estimate-relevant knowledge is organised and searched according to ordered reference classes that are based on binary cue values. Two experiments tested two main predictions derived from QuickEst with respect to the memory search and estimation behaviour of human participants. The results provided no evidence that QuickEst is used in numerical estimation processes. As alternative explanation of our findings, we discuss a cyclic sampling mechanism that retrieves information from memory according to their associative strength.  相似文献

People frequently continue an investment despite a negative outcome or sunk cost. Such irrational persistence in a losing course of action has been termed escalation of commitment. Although several explanations of escalation of commitment have been proposed, none of them accounts for all determinants that have been empirically demonstrated. Based on a review of previous research, a conceptualisation is introduced of how escalation of commitment is affected by 4 task dimensions: type and nontransparency of decision goal, nontransparency of sunk costs, time course of sunk costs, and accountability. A more inclusive theory that subsumes escalation of commitment is offered as an alternative that may be developed to account for the effects of the task dimensions.  相似文献

The feeling of regulatory fit is thought to arise from the right kind of goal pursuit, but some studies imply that it may be evoked even by lesser involvement in the right kind of strategies. The present experiment explored the minimum of involvement necessary to evoke regulatory fit. Participants (N = 71) first completed a regulatory focus manipulation task and were then led to believe that they would receive either rich or accurate information concerning vegetable sterols, evoking beliefs that they used eager or vigilant information search strategies. In reality, all participants received the same information. Participants in promotion focus reported more positive attitudes in the rich information condition, whereas prevention-focused participants reported more positive attitudes in the accurate information condition. The results showed that regulatory fit can be evoked through mere thought, without actual goal pursuit and even without engagement in the goal pursuit strategies.  相似文献
