The Experimental Psychology Society (EPS), established in 1946, is one of the UK's leading learned societies for experimental psychology. The EPS Essex meeting marks the Society's 80th anniversary and brings together researchers across cognitive, developmental, social, and neuropsychology to present and discuss cutting-edge experimental work.
Hosted at the University of Essex, the 2026 meeting features a flagship anniversary symposium entitled Where is experimental psychology now, and where will it be at 100? The programme includes the 33rd EPS Prize lecture by Melissa Colloff (with an accompanying symposium organised by Markus Bindemann) and the 15th Frith Prize Talk by Denise Cadete. Abstract submissions were reviewed for eligibility and selected through the Society's established meeting process, with oral and poster presentations spanning the breadth of contemporary experimental psychology.
Conference dates: 1–3 July 2026
Location: University of Essex, Colchester, Essex, UK
Format: In-person (talks, symposia, posters & conference dinner)
Local organiser: Maria Laura Filippetti
Organiser: Experimental Psychology Society
The three-day programme at Essex celebrates eight decades of the Experimental Psychology Society with invited prize lectures, themed symposia, and contributed oral and poster presentations. The anniversary symposium reflects on the past, present, and future of experimental psychology, while prize sessions highlight outstanding mid-career and early-career contributions to the field.
A conference dinner is held on 2 July 2026 at Church Street Tavern, Colchester, with transport arranged between the university campus and the venue. The meeting provides a major forum for UK and international experimental psychologists to share empirical findings, methodological advances, and theoretical developments.
Title: Network Models for Assessing Comorbidity between Stuttering and ADHD
Presenter: Dr. Fjorda Kazazi
Presentation type: Accepted oral / podium presentation
Abstract: Overlap of symptoms between people who stutter (PWS) and people with ADHD (PWADHD) is often claimed. However, whether these overlaps reflect a single underlying condition with shared cognitive mechanisms or distinct cognitive architectures remains unclear. This study tested whether the underlying cognitive architectures of stuttering and ADHD differ. Controls (N = 67), PWADHD (N = 79), and PWS (N = 33) were assessed on stuttering, ADHD traits, and phonological working memory (PWM), a known risk factor across both conditions. Network models examined relationships among these domains, quantifying connectivity and comparing network structure and centrality across groups.
Results showed that while controls and PWADHD exhibited broadly similar architectures, both differed from PWS. PWM emerged as a central node in all groups, but its connectivity varied: PWM affected attention in controls and PWADHD, but not in PWS. Stuttering severity affected PWM in PWADHD and PWS but the link was stronger in PWS. Higher stuttering rates correlated positively with attention issues in PWADHD and negatively in PWS.
Findings do not support a unified network structure consistent with a single shared underlying mechanism, but instead support partially distinct cognitive architectures. The results highlight network approaches and a differential mechanistic role of PWM across conditions.
