What are the defining characteristics of a good psychology study? We received this excellent question from a listener and decided to do a whole episode on this idea. Some of the topics discussed: When’s the last time you saw a psych study that only reported a t-test? Dan and James’ new paper on worry and heart rate variability Skepticism towards studies with many variables and ‘novel’ statistical approaches (that tend to always provide marvellous results) Repeated measures ANOVAs vs. linear mixed models Publishing convenient ideas, even if they’re wrong Fishing expeditions The ‘nocebo’ effect in action What are markers of study quality? Pre-registering studies - can it be gamed? The gradual improvement of psychology studies Links Dan and James' new paper on worry and heart rate variability http://www.ncbi.nlm.nih.gov/pubmed/27255891 The paper that said "Encouraging experimental psychologists to use LMMs was like giving shotguns to toddlers.” http://www.ncbi.nlm.nih.gov/pubmed/25657634 Facebook page ht

Heart rate variability is becoming incredibly popular in the biobehavioral sciences yet there's no standard for how this research is reported. In this episode, Dan and James discuss their latest paper where they propose heart rate variability reporting guidelines. They also talk about saunas (why not?) and why 'sympathovagal balance' should be abandoned.

Meta-analysis has become an increasingly popular tool used by many scientists to synthesise data. However, it's not without its detractors — from H. J. Eysenck, Ph.D., calling it "an exercise in mega-silliness" in 1978, to J. A. J. Heathers Ph.D., describing its use as a "profound moral failing" (he's half-serious) in 2016. In this episode, Dan defends meta-analysis against more recent criticisms put forward by James and offers suggestions on how meta-analysis can be improved.
