Professor Boyle has spent over three decades undertaking quantitative research in the field of psychometrics, as related to the measurement of individual differences in personality, intelligence, and motivation, as well as undertaking studies within the fields of neuropsychology, clinical psychology, and educational psychology. In more recent years, he has applied his extensive research skills to studies within the broad fields of medical/health psychology, and has undertaken many studies within the area of women's health. Lately, he has focused his attention more on research topics pertaining to men's health.My research focuses on the study of individual differences with an emphasis on personality and intelligence, including emotional intelligence. These studies and resulting publications are theoretical and practical as well as correlational and experimental. The opportunity for cross-cultural studies has significantly broadened the scope of this research. Also, my recent research interests in emotional intelligence, including emotions and social cognition is motivated by the current emphasis on prevention, resiliency, psychological health, and building capacity. Publications of some of my more recent books, book chapters and journal articles are included in the publications link.
