Personal profile


Dr Claire Cullen (she/her/hers) is an Assistant Lecturer in Psychology, at the School of Humanities, South East Technological University, Waterford. She completed her PhD in Experimental Behavioural Social Psychology at Maynooth University under the supervision of Professor Dermot-Barnes-Holmes (2016) where she developed, refined and tested the Implicit Relational Assessment Procedure (IRAP) for the assessment of implicit anti-gay bias. Her PhD (funded by the Irish Research Council for Science, Engineering & Technology; the Association of Behaviour Analysis International; and Maynooth University) constituted the first ever systematic study to investigate the malleability of implicit & self-reported homonegativity. Part of that work involved using event related brain potentials (ERPs) analyses in an attempt to vaidate the Homonegativity-IRAP that she developed. The work also involved the development and validation of a sensitive multidimensional screening tool for the assessment of sexual orientation. 

Claire has a demonstratable record of commitment to equality, diversity and Inclusion (EDI). She co-authored the Psychological Society of Irelands (PSI) professional practice guidelines for working with LGB clients (2009-2015) and the first PSI Policy on Promoting Equality and Inclusive Practice (EQuIP: 2008; revisions: 2009; 2010).  As a student, Claire (founding Secretary) established the PSI Student Affairs Group (SAG: 2007) along with Dr Bredan Rooney (founding Chair). She was the founding Chair of the PSI Sexual Diversity and Gender Issues Special Interest Group (SDGISIG: 2007-2010); a founding committee member of PSIs Culture and Ethnic Diversity Special Interest Group (CEDSIG: 2008); and a founding  committee member of the PSI Equality and Inclusive Practice working-group (EQuIP: 2008). Claire served as the first elected PSI co-representative to the International Network of Lesbian, Gay, Bisexual, & Transgender Issues in Psychology (INET; 2008-2010), having been nominated by Dr Clinton Anderson (Division 44: American Psychological Association (APA)). Claire is an elected professional member of the International Society for the Scientific Study of Sexuality (SSSS). She has published international peer-reviewed research on sexual diversity, gender issues, and more recently, sex education. She recently served on the Board of Directors at Outhouse, Dublin’s LGBT community resource centre (2018-2020).
