Background: Differential learning is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed, Web of (...) Science, and Google Scholar were searched until February 3, 2020. To be included, studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method, studies had to describe the effects on one or more measures of performance in a skill or movement task, and the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase as well as for the retention phase was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found. (shrink)

Introduction Marina Sbisà University of Trieste 1. Pragmatics and philosophy It is well known that pragmatics – like many branches of the social and even ...

This encyclopaedia of one of the major fields of language studies is a continuously updated source of state-of-the-art information for anyone interested in language use. The IPrA Handbook of Pragmatics provides easy access - for scholars with widely divergent backgrounds but with convergent interests in the use and functioning of language - to the different topics, traditions and methods which together make up the field of pragmatics, broadly conceived as the cognitive, social and cultural study of language and communication, i.e. (...) the science of language use. The Handbook of Pragmatics is a unique reference work for researchers, which has been expanded and updated continuously with annual installments since 1995.

This article starts from the observation of current changes in the nature of a globalizing public sphere for which older structural boundaries have lost much of their relevance. Though the public sphere has traditionally been a topic for social scientists, a redefinition in terms of the realm of publicly accessible meaning, and of struggles over socially and politically important meaning, necessitates a contribution from the humanities. In particular, linguistic pragmatics, providing tools for an analysis of the way in which explicit (...) and implicit forms of meaning interact in the process of generating meanings, is argued to be a useful instrument. The argument is supported with an analysis of the differences in meaning landscapes that emerge even in different-­language versions of the ‘same’ text, illustrating how dependent publicly available meaning is on basic pragmatic processes. The article concludes that a maturing science of language use is therefore needed to understand variations in the accounts of social and political reality that people in a globalizing public sphere live by.
