Sam Parsons: Postdoctoral Research Associate

Interests in Research

: is being supported right now by an ESRC grant given to Prof. Elaine Fox to investigate the part affective flexibility plays in teenage concern and the emergence of emotional vulnerability. investigating underlying mechanisms using behavioral and EEG methods.

In addition to researching the cognitive-affective mechanisms behind teenage worry, I strive to contribute in some tiny way to the advancement of psychological science. This highlights the significance of routinely estimating and reporting the reliability of our measurements, which at times encourages open and reproducible research practices and at other times frustrates others.

My name is Sam Parsons. I’m a Postdoctoral Research Associate in the Department of in Experimental Psychology at Oxford University. I work in the Oxford Centre for Emotion and Affective Neuroscience, aka OCEAN. Just in case you’re here for the cat, this ginger monster is called Beau.

As well as investigating cognitive-affective processes implicated in adolescent worry, I try to do my own small bit for the improvement of psychological science. Sometimes this is promoting open and reproducible research practices; others it is frustrating others by highlighting the importance of routinely estimating and reporting the reliability of our measurements. Mostly, I’d just like us all to get along and do good research.

I am happy to be contacted to discuss reliability of cognitive measures - particularly if you have questions about my splithalf package and need assistance with it.

(I try to keep this website up to date, however it may fall slightly behind. I do keep my CV up to date, so please do refer to that)

About me I am a Radboud Excellence Initiative Postdoctoral Research Fellow. I work in the Lifespan Cognitive Dynamics Lab based at the Donders Institute. I did my DPhil in Experimental Psychology at the University of Oxford.

My current work is focused on the reliability of longitudinal structural brain imaging data across brain regions, structural measures, and studies. My aim is to support developmental cognitive neuroscience study changes in brain structure and function by focusing on sources of reliability and error. My core approach will be based on intra-class effect decomposition, closely tied to generalisability theory. These models extract sources of variation in order to explore where the variation/error comes from in the model, moving beyond a single metric of reliability (e.g. ICC for test-retest). I believe it is important to support others who may want to use these approaches, so I will be dedicating time to share code and develop tutorials.

I am happy to be contacted to discuss reliability of cognitive measures - particularly if you have questions about my splithalf package (see below) and need assistance with it.

Open Scholarship I try to do my own small bit for the improvement of psychological science and open scholarship. Amy Orben, Sophia Cruwell, and I co-founded the ReproducibiliTea Journal Clubs - now a large international community of Journal Clubs where folks talk about openness, reproducibility, and improving research practices. Flavio Azevedo and I also co-founded a Framework for Open and Reproducible Research Training (FORRT), a pedagogy-focused community working to support those seeking to incorporate News open and reproducible practices into their teaching and mentoring.
