Modern graphical and computational techniques for detecting nonlinearity in psychological data sets are presented. These procedures
allow researchers to determine the information complexity of temporal data, using physiological and psychological measurements,
and to provide evidence for chaos in time series contaminated by measurement noise. Problems with noise reduction and appropriate
experimental control, using surrogate time series, are discussed, and applications of the technology are illustrated, using
response time, handwriting, and typing data sets. In an experimental application of appropriate nonlinear analysis procedures,
the results of a time series prediction experiment confirm that some subjects are sensitive to chaos. In contrast to previous
attempts demonstrating sensitivity to chaos, the experiment reported here employs surrogate series to control for linear stochastic
aspects of the stimulus sequences, such as autocorrelation. Recommendations for the selection of appropriate software for
performing nonlinear analyses are presented, including a comprehensive list of World-Wide Web sites offering such software. 相似文献

Die Anti-NMDA(N-Methyl-D-Aspartat)-Rezeptor-Enzephalitis ist eine seltene autoimmunologisch bedingte Erkrankung mit verschiedenen neuropsychiatrischen Symptomen, die durch den Nachweis von NMDA-Rezeptor-Antikörpern im Liquor diagnostiziert wird. Die gängigen Behandlungsprotokolle beinhalten ein Stufenschema der Immuntherapien; allerdings beruhen die therapeutischen Entscheidungen derzeit auf einem Grad-IV-Evidenzniveau. Wir berichten hier über zwei junge, unterschiedlich betroffene Patientinnen und beschreiben die Therapiestrategien inklusive der Kombination verschiedener Immuntherapien einschließlich Ocrelizumab und Überlegungen bezüglich Fertilitätserhalt. 相似文献

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., “What is Robin doing?”), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, “Where does Robin work?”), or unknown (e.g., “What is Robin's favorite food?”). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism. 相似文献

Evidence-based practice, developed in clinical medicine, is being applied to community health programs. Barriers to implementation of evidence-based practice noted in clinical medicine are likely to exist in community health settings and may be complicated by the nature of community health programs. These barriers include accessibility and availability of relevant data, social and political considerations of program decision-making, and conflicting expectations for evaluation research. This paper discusses barriers to both amassing evidence for practice and using evidence for decision-making in community health. The potential for conflict between practice goals set by evidence-based thinking and those set by community health organizations is also discussed. Implications for evaluations of community health programs are raised and recommendations for improving access to and use of evaluation information are made. 相似文献

Organizational acquisitions may be characterized by the degree of friendliness or hostility as well as the degree of autonomy or absorption of the organizations following the merger. This study examined judgments of fairness across four types of organizational acquisitions. Students read fictitious newspaper accounts of a university acquisition and rated their expectations and perceptions of fairness about possible changes. Results indicated that in an acquisition, both the procedures used and the outcomes provided influenced how fair the acquisition was perceived. As predicted, the relative importance of procedures and outcomes in overall perceptions of fairness shifted depending on the context of the acquisition. As the desirability of the acquisition increased, individuals placed greater importance on the procedural elements. In a friendly and low integration acquisition, the processes and outcomes became equally important. Individuals faced with a high integration acquisition expected more unfair changes and fewer fair changes to occur. Furthermore, these results highlight the importance expectations play in perceptions of fairness. The type of acquisition will influence expectations for fair treatment. Under less desirable conditions (hostile and high‐integration mergers), organizations should take steps early in the process to manage fairness perceptions.

This article reviews evidence indicating that, in most circumstances, positive affect enhances problem solving and decision making, leading to cognitive processing that is not only flexible, innovative, and creative, but also thorough and efficient. These results have implications regarding consumers’ potential reactions to affect generated by ads, products, consumption situations, and service encounters. These cognitive effects of positive affect are considered in the context of effects on social interaction that show that positive affect leads to helping, generosity, and interpersonal understanding. Together, these findings suggest implications especially for customer satisfaction, and particularly for a role for employee positive affect, or employee satisfaction, in generating customer satisfaction. Moreover, studies specifically in the domain of medical decision making and problem solving indicate that these implications would apply to the specific areas of doctor–patient interaction, medical decision making, and medical consumer satisfaction. Finally, it is suggested that the benefits of positive affect be considered when formulating healthcare policy and be included in economic models and policy decisions more generally as well. 相似文献

Genetic Influences on Anxiety in Children: What we’ve Learned and Where we’re Heading 总被引:5,自引:0,他引:5
Anxiety is a common problem, typically beginning early in life. This article explores reasons for individual differences in
levels of anxiety among children, by reviewing the genetic literature. The plethora of research to date has demonstrated clearly
that both genes and environmental influences play important roles in explaining differences in levels of anxiety of various
types among children. This has encouraged researchers to search for specific genes and environmental influences upon anxiety.
Despite important progress in identifying links between anxiety and specific genes—including associations between serotonin
and dopamine genes and different symptoms of anxiety—overall, progress has been slow because multiple genes of small effect
size are likely to influence anxiety. This article explains how the hunt for genes involved in anxiety is likely to benefit
from genetically sensitive research, which examines the co-occurrence of symptoms; includes measures of the environment; and
examines endophenotypes and risk pathways. 相似文献
