Alexander T. Latinjak is a senior lecturer and the course leader of the BSc (Hons) Sport and Performance Psychology at the University of Suffolk, and visiting researcher at the EUSES Schools of Health and Sports Sciences in Catalonia. Although Alexander wrote his dissertation on strategic self-talk interventions for tennis players, he has recently been more intensively involved in the study of spontaneous and goal-directed self-talk. His research led to the design of a reflexive self-talk intervention and the development of a conceptualisation of self-talk based on the distinction between organic and strategic self-talk.
