The Think/No-Think Paradigm



Role: Lead researcher

This was part of my PhD research. It had the following aims:
  • Extension of the Think/No-Think paradigm 
  • The ability to suppress unwanted using the Think/No-Think paradigm in relation to two psychological traits (OCD and PTSD)
  • Using the Think/No-Think paradigm as a countermeasure in Brain Fingerprinting
This project was completed in collaboration with Prof Michael Anderson at the MRC Cognition and Brain Sciences Unit, University of Cambridge, UK.
