New Important Several months Hypothesis in the Second Code Buy: A mathematical Feedback and you may a good Reanalysis

For the second code acquisition research, the crucial period hypothesis ( cph ) retains that form between learners’ decades as well as their sensitiveness to help you 2nd words type in are low-linear. So it report revisits the fresh indistinctness based in the books with regard compared to that hypothesis’s scope and forecasts. Even though their scope is obviously delineated and its own predictions try spelt aside, however, empirical knowledge–having pair exceptions–use analytical (statistical) equipment which might be irrelevant with respect to the predictions made. This report talks about analytical fallacies well-known in the cph search and you will portrays an option analytical strategy (piecewise regression) as a reanalysis out-of a couple of datasets out of a 2010 papers purporting to have discovered mix-linguistic evidence in preference of the brand new cph . It reanalysis demonstrates the particular age activities forecast of the cph are not mix-linguistically strong. Applying the principle out-of parsimony, it is figured many years designs from inside the second words buy was perhaps not ruled of the a serious period. Continue reading →
