Research summary

My primary research focuses on the promotion and effectiveness of open research practices. As part of this work, I co-founded Registered Reports, Exploratory Reports, Verification Reports, the Transparency and Openness Promotion guidelines, the Royal Society Replications initiative, the UK network of open research working groups, the Peer Reviewers' Openness Initiative, the UK Reproducibility Network (UKRN), the GW4 Undergraduate Psychology Consortium programme for promoting reproducible science, the Royal Society Rapid Review Network for COVID-19 Registered Reports, and the Peer Community in Registered Reports. I currently chair the Registered Reports committee supported by the Center for Open Science, serve on the UKRN steering committee and sit on the Advisory Board of Nature Human Behaviour.

I am author of the Seven Deadly Sins of Psychology: A Manifesto for Reforming the Culture of Scientific Practice, which won the 2018 British Psychological Society Book Award (Best Academic Monograph) and the 2018 PROSE Award from the Association of American Publishers. From 2013-2018 I was a freelancer writer at the Guardian where I co-hosted the psychology blog, Head Quarters

In my scientific research I have used brain stimulation (TMS, TES) and brain imaging techniques (fMRI, MRS, MEG) to understand cognitive control, attention and awareness in the human brain, as well as translational applications of cognitive neuroscience in the domain of obesity and behaviour change. Over the last 15 years, my team has also made methodological contributions to the simultaneous combination of TMS and MRI, in addition to technical advances in TMS methods to improve the precision and reliability of cortical stimulation.

Alongside these interests I have pursued research on the relationship between science and the media, and the role of science in shaping evidence-based public policy.


























My research addresses questions across a range of fields. My primary interest is the field of metascience, especially research on the effectiveness of open research practices including Registered Reports and related policy initiatives for improving scientific quality. Within cognitive neuroscience, I have interests in understanding attention and impulse control, and translational applications in clinical fields such as addiction.

In 2012 I jointly established the Insciout research group together with Petroc Sumner, Jacky Boivin and Andy Williams. Insciout was a collaborative project between the School of Psychology and the School of Journalism, Media and Cultural Studies. Our aim was to identify causes of error in the translation of science to the news, and to develop evidence-based guidelines for best practice in science/media interactions. Some of our key publications in this area can be read here and here.

In 2014 I formed a research team that proposed the formation of the UK Evidence Information Service, a research-led initiative that would facilitate interaction between academia and politicians in the service of evidence-based policy. In 2016 we published the results of the first community-led consultation of UK parliamentarians in this field, which suggest that the proposed service would have high demand among MPs. Our final report on the proposal can be found here.

Research topics and related papers

Open Science

Psychology and cognitive neuroscience are in the midst of a credibility revolution that is being advanced through the adoption of practices that boost the transparency of the research process. Since 2014 I have served as chair of the Registered Reports Committee of the Center for Open Science (COS). Registered Reports are a form of empirical article that tackles publication bias and various forms of reporting bias (such as p-hacking and hindsight bias) by conducting peer review before data collection and analysis. I am also a member of the COS Transparency and Openness (TOP) Guidelines committee, which proposes a series of guidelines for academic journals to improve the credibility of published work. In 2015 we published the TOP guidelines in the journal Science, led by COS Executive Director Brian Nosek. I have also worked closely with colleagues to establish the Royal Society Replications initiative, the Exploratory Reports and Verification Reports article types, the UK network of open research working groups, the Peer Reviewers' Openness Initiative, the UK Reproducibility Network (UKRN), the GW4 Undergraduate Psychology Consortium programme for promoting reproducible science, and the Royal Society Rapid Review Network for COVID-19 Registered Reports.

Cognitive control

Neural mechanisms of cognitive control enable us to coordinate, execute, and update behaviour. The prefrontal cortex has long been associated with cognitive control but the architecture of the prefrontal system is one of the great unsolved mysteries in cognitive neuroscience. Within the broad field of cognitive control (or ‘executive functions’), our research focuses on understanding the neural basis of response inhibition, response selection, and the link between inhibition and risk-taking (including gambling and eating behaviour), principally through the application of training methods, TMS and TES.

Attention and awareness

Our sensory environment contains a vast quantity of information, only a fraction of which can guide behaviour. Brain mechanisms of attention are crucial for enhancing the processing of stimuli that are relevant to current goals. Within the field of attention, our research focuses on the use of TMS and fMRI to understand the cognitive neuroscience of attentional control and spatial representations. We are also interested in the neurophysiology and neurochemistry that supports consciousness in the occipital and frontal cortex.

Concurrent TMS and MRI

The combination of TMS and neuroimaging (MRI, EEG) provides a unique window on human brain function, with broad applications and implications across the cognitive and clinical neurosciences. By applying TMS within the MRI scanner, we can directly observe the physiological consequences of stimulation both locally (at the site of stimulation) and in remote interconnected brain regions. The integration of TMS and different imaging techniques also holds great promise for revealing the mechanism by which TMS influences neurophysiology and neurovascular coupling.

We previously established concurrent TMS-MRI at CUBRIC via the Academic Expertise for Business (A4B) grant programme, an initiative of the Welsh Assembly Government that funds links between academia and industry in Wales. Our industrial partners on this project were Welsh neuromedical companies Magstim and Dymed. Together we developed passive shim technology that nearly eliminates one major source of interference between TMS and MRI.

TMS methods

The application of TMS in cognitive neuroscience carries a variety of technical and interpretative challenges. As a neurostimulation method, one critical issue is the control of TMS intensity. What strength of TMS is sufficient to yield effective (but not excessive) stimulation of cortical tissue? We have found that the extent of cortical activity during TMS is steeply related to the distance between the scalp and cortex. Even a difference of 1mm in the scalp-cortex distance between different sites can have a measurable and reliable effect on TMS-evoked behaviour. We have therefore developed a scaling method for calibrating the intensity of TMS according to scalp-cortex distance, thus enabling more precise and comparable stimulation of different regions.

The relationship between science and the media - the Insciout project

We are interested in how press releases issued by universities and academic journals influence the reporting of science news in the media. By understanding both positive and negative effects we aim to formulate an evidence-based policy for maximizing the impact and accuracy of science-related public relations. This project is supported by an ESRC transformative grant, the Wellcome Trust, and the British Psychological Society. It also benefits from our close relationship with the Science Media Centre.

The Evidence Information Service

From 2014-2019 we undertook research on the potential value of a new service to facilitate communication between academic researchers and UK politicians and civil servants. The aim of the Evidence Information Service (EIS) would be to act as a rapid matchmaking and advisory service, connecting politicians with experts in academia and industry. The EIS would host a database of scientists who are willing to commit their time voluntarily to help policy makers obtain and interpret the most reliable evidence on specific issues. Such activities will include the provision and explanation of peer-reviewed literature, statistical consulting, and the critical assessment of data or conclusions.
