Click the reference below articles to access the paper at my Kudos profile. The Kudos page contains archived versions where the paper is not free at the publisher and lay summaries for brief, simple descriptions of the studies. In some cases, archived versions are pre-prints (without the benefits of peer-review), post-prints (incorporating comments by reviewers), or the publisher’s final PDF. Where there isn’t an archived version, the paper is usually available for free from the journal website. If you would like a copy of the final version, I can send that by email if you contact me. I have tried, where possible, to make the datasets available for each paper. (* indicates co-author is a student)
