Prof. Dr. Janssen's research interests include the psychophysiology of sexual desire and arousal, the effects of emotions on sexual response and behavior, and relationships, sexuality, and health. With his research he aims to improve our understanding of the determinants of sexual aggression, risky sexual behavior, sexual dysfunction, hypersexuality, and sexual and relationship satisfaction.
A large part of Dr. Janssen's work focuses on the award-winning Dual Control Model of Sexual Response, which he introduced with John Bancroft, M.D. and which, with its focus on individual differences in the propensity for sexual excitation and inhibition, opened up a new research agenda with wide relevance.
Research Interests:
- Sexual Psychophysiology
- Sexuality and Close Relationships
- Sexual Inhibition and Excitation
- Sexual Aggression
- Risky Sexual Behavior
- Hypersexuality
- Sexual Dysfunction.
Prof. Dr. Janssen also studies the relationship between sexual and nonsexual emotions (e.g., happiness, sadness, anger) and how these, separately and in interaction, influence sexual functioning, behavior, and satisfaction, in individuals as well as in couples.
