Most of my decks are pretty specific to idiosyncratic courses I've done and I don't feel they'd be useful to others. These ones might be a bit more generally applicable if you're interested in the area:

Advanced psychological statistics - mainly about various kinds of modelling approaches and meta-analysis.

Quantitative and qualitative research methods - fairly basic research methods stuff

Functional neuroanatomy and neuroscience methods - basic stuff about various imaging techniques, a little bit of psychopharmacology
