What happens when people gather in crowds – whether for political rallies, protests, football games or religious pilgrimages? Stephen Reicher, PhD, of St. Andrew’s University in Scotland, discusses why “mob mentality” is a myth; other misconceptions about crowd behavior; the role of leaders in groups and what can we learn from re-examining some classic psychology studies on obedience to authority; and what we’ve learned about leaders, followers, group identity and collective behavior from the COVID-19 pandemic.

Factitious disorder, more commonly known as Munchausen syndrome, is a mental health disorder in which people fake serious illness to gain sympathy, attention and support. A related disorder, Munchausen by proxy, or factitious disorder imposed on another, is a form of abuse in which caregivers make up or induce illness in their children. Psychiatrist Marc Feldman, MD, and psychologist Janet Cahill, PhD, discuss researchers’ evolving understanding of these disorders, how common they are, the phenomenon of “Munchausen by internet” where people lie to strangers online, and whether there are any effective therapies for these disorders.

Laurence Steinberg, PhD, of Temple University, talks about how these changes are affecting the relationship between parents and their grown children, what young adults wish their parents understood about their lives, and how parents and adult children can resolve conflicts and build a strong relationship together.

Cheri Levinson, PhD, of the University of Louisville, discusses myths about eating disorders, how our toxic diet culture combined with genetic vulnerability can spur eating disorders, what treatments are available, and how researchers are using new technologies to come up with more effective personalized treatments and expand access to care.
