There have been many published studies aiming to identify temporal changes in river flow time series, most of which use monotonic trend tests such as the Mann–Kendall test. Although robust to both the distribution of the data and incomplete records, these tests have important limitations and provide no information as to whether a change in variability mirrors a change in magnitude. This study d...

Biological studies into antidepressant drug action and into the aetiology of depression were highly active areas of research in the 1960s and 1970s but, arguably, have now lost some of their impetus and direction. Many investigations seem to have come to a natural end and there is a need for the subject to make a quantum leap to promote its development. It is recognized however, that advances h...

A region of the brain called the putamen has a central role in procedural memory consolidation during sleep.

Switching between mental sets has been extensively investigated in both experimental and individual differences research using a wide range of task-switch paradigms. However, it is yet unclear whether these different tasks measure a unitary shifting ability or reflect different facets thereof. In this study, 20 task pairs were administered to 119 young adults to assess 5 proposed components of ...
