Replicability of findings is at the heart of any empirical science. The aim of this article is to move the current replicability debate in psychology towards concrete recommendations for improvement. We focus on research practices but also offer guidelines for reviewers, editors, journal management, teachers, granting institutions, and university promotion committees, highlighting some of the emerging and existing practical solutions that can facilitate implementation of these recommendations. The challenges for improving replicability in psychological science are systemic. Improvement can occur only if changes are made at many levels of practice, evaluation, and reward.

We assessed the effects of aging in the transfer of motor learning in a sequential manual assembly task that is representative for real working conditions. On two different days, young (18–30 years) and middle-aged adults (50–65 years) practiced to build two products that consisted of the same six components but which had to be assembled in a partly different order. Assembly accuracy and movement time during tests, which were performed before and after the practice sessions, were compared to determine proactive and retroactive transfer. 相似文献

The recent Ebola outbreak in West Africa began in the spring of 2014 and has since caused the deaths of over 6,000 people. Since there are no approved treatments or prevention modalities specifically targeted at Ebola Virus Disease (EVD), debate has focused on whether unproven interventions should be offered to Ebola patients outside of clinical trials. Those engaged in the debate have responded rapidly to a complex and evolving crisis, however, and this debate has not provided much opportunity for in-depth analysis. Additionally, the existing literature on access to unproven therapies has focused on contexts like HIV/AIDS and oncology, which are very different than the Ebola epidemic. In this paper, we examine the ethical issues surrounding access to unproven therapies in the context of the recent Ebola outbreak to yield new insights about this controversial and unsettled issue. We argue first that, in this context, the interests of patients in obtaining access to unproven therapies are not fully aligned with the interests of their providers and drug developers. Second, we focus on the resource constraints facing providers, funders, and patients and conclude that they often counsel against the use of unproven interventions against EVD. 相似文献

Parkinson’s disease is a neurodegenerative disease with the cardinal symptoms bradykinesia, rigidity and tremor. In 1817, James Parkinson already described in his "Essay on the Shaking Palsy" in addition to the motor symptoms also autonomic, cognitive and behavioral disturbances (Parkinson, An essay on the shaking palsy. Sherwood, Nealy and Jones, London, 1817). Their impact on quality of life has been underestimated until more recent times. Dopamine dysregulation syndrome is an iatrogenic disturbance, characterized by an addictive pattern of dopamine replacement therapy use. Despite good control of motor symptoms, patients often increase doses of dopamine replacement therapy in excess of those normally required. Consequently these behavioral disorders may also result in social and professional problems. 相似文献

Schizophrenia is characterized by an abnormal dopamine system, and dopamine blockade is the primary mechanism of antipsychotic treatment. Consistent with the known role of dopamine in reward processing, prior research has demonstrated that patients with schizophrenia exhibit impairments in reward-based learning. However, it remains unknown how treatment with antipsychotic medication impacts the behavioral and neural signatures of reinforcement learning in schizophrenia. The goal of this study was to examine whether antipsychotic medication modulates behavioral and neural responses to prediction error coding during reinforcement learning. Patients with schizophrenia completed a reinforcement learning task while undergoing functional magnetic resonance imaging. The task consisted of two separate conditions in which participants accumulated monetary gain or avoided monetary loss. Behavioral results indicated that antipsychotic medication dose was associated with altered behavioral approaches to learning, such that patients taking higher doses of medication showed increased sensitivity to negative reinforcement. Higher doses of antipsychotic medication were also associated with higher learning rates (LRs), suggesting that medication enhanced sensitivity to trial-by-trial feedback. Neuroimaging data demonstrated that antipsychotic dose was related to differences in neural signatures of feedback prediction error during the loss condition. Specifically, patients taking higher doses of medication showed attenuated prediction error responses in the striatum and the medial prefrontal cortex. These findings indicate that antipsychotic medication treatment may influence motivational processes in patients with schizophrenia. 相似文献

Genetic testing is becoming increasingly available for cardiac channelopathies, such as long QT syndrome and Brugada syndrome, which can lead to sudden cardiac death. Test results can be used to shape an individual’s medical management and to identify at-risk family members. In our qualitative study, all participants had a personal or family history of a diagnosed cardiac arrhythmia syndrome or sudden cardiac death. Open-ended interviews were conducted individually and in focus groups. Interviews were audio recorded, transcribed verbatim, and analyzed using a qualitative grounded-theory approach. Of 50 participants, 37 described their motivations for pursuing genetic testing for long QT syndrome or another cardiac channelopathy. Participants’ motivations included: to find an explanation for a family member’s sudden death, to relieve uncertainty regarding a diagnosis, to guide future medical management, to allay concern about children or other family members, and to comply with recommendations of physicians or family members. Perceived reasons not to pursue genetic testing included denial, fear, and lack of information. The genetic counseling and informed consent process can be enhanced by understanding and addressing an individual’s internal and external motivations either for or against pursuing genetic testing. 相似文献

In the U.S., women account for over a quarter of the approximately 50,000 annual new HIV diagnoses and face intersecting and ubiquitous adversities including gender inequities, sexism, poverty, violence, and limited access to quality education and employment. Women are also subjected to prescribed gender roles such as silencing their needs in interpersonal relationships, which may lessen their ability to be resilient and function adaptively following adversity. Previous studies have often highlighted the struggles encountered by women with HIV without focusing on their strengths. The present cross-sectional study investigated the relationships of silencing the self and socioeconomic factors (education, employment, and income) with resilience in a sample of women with HIV. The sample consisted of 85 women with HIV, diverse ethnic/racial groups, aged 24–65 enrolled at the Chicago site of the Women’s Interagency HIV Study in the midwestern region of the United States. Measures included the Connor-Davidson Resilience Scale -10 item and the Silencing the Self Scale (STSS). Participants showed high levels of resilience. Women with lower scores on the STSS (lower self-silencing) reported significantly higher resilience compared to women with higher STSS scores. Although employment significantly related to higher resilience, silencing the self tended to predict resilience over and above the contributions of employment, income, and education. Results suggest that intervention and prevention efforts aimed at decreasing silencing the self and increasing employment opportunities may improve resilience. 相似文献
