Jean Mercer, PhD

Founding Fellow

Moorestown, New Jersey, USA

Psychologist Jean A. Mercer, PhD, is the foremost spokesman for science-based and humane psychotherapy for adopted and foster children. In the late 1990s, Dr Mercer encountered “Complementary and Alternative Medicine” (“CAM”) in the form of “Attachment (Holding) Therapy” and “Rebirthing.” Upon the therapist-caused death of 10-year-old Candace Newmaker in 2000, she began to speak out and publish critiques of “alternative” mental health interventions.

Prof Mercer is retired from teaching at Richard Stockton College of New Jersey, taking the position of Professor Emerita of Psychology there.  Since her retirement, she has devoted her time to countering the claims of “CAM” psychotherapists that their methods are evidence-based.  Her blog on Psychology Today regularly addressed unvalidated practices. Dr Mercer has also been involved with issues of inappropriate use of psychological testing in child custody cases and has both testified and published on this topic. She is currently working on a study of historical factors that may help to define “CAM” practices more clearly.  One of her co-authored articles on “alternative” mental health interventions was short-listed for the “Pro Humanitate” award. She is a major contributor to the Wikipedia article on Attachment Theory which received “featured article” status in spite of efforts of “CAM” proponents to subvert it.  In 2007 she was an expert witness in the child abuse trial of Sylvia Vasquez, a California mother who used Attachment Therapy-related methods with three of her adopted children.

Dr Mercer received her PhD in general psychology from Brandeis University in 1968. Her dissertation investigated the effects of vestibular stimulation on sound localization and was followed by an invitation to apply to the “Scientist as Astronaut” program. Remaining earthbound, however, she began a teaching career that emphasized research methods and statistics. Her research in developmental psychology includes work on factors in the timing of human lactation and on pain responses in premature babies. She was president of the New Jersey Association for Infant Mental Health for five years and remains an active board member.

Dr Mercer has two blogsites: Child Myths and The Study of Nonsense.

Alternative Psychotherapies: Evaluating Unconventional Mental Health Treatments (2014) addresses concerns about current and newly-emerging mental health treatments that are considered "unconventional." In a parallel to complementary and alternative medical treatments, alternative psychotherapies lack research support, are at odds with established information about human personality and development, and may actually be harmful. Professionals and students in the helping professions may find such treatments confusing and difficult to differentiate from emerging therapies that have not yet established a foundation of evidence; this is especially problematic if clients propose using unconventional therapies they have found on the Internet. Alternative Psychotherapies examines a series of unconventional treatments in terms of the research supporting them, their theoretical and historical backgrounds, and the potential or documented adverse events that may be associated with them. Therapies for both adults and children are included, and topics range from recovered memory therapies to bodywork to treatments for autism and to special education issues. Alternative psychotherapies frequently share certain historical backgrounds, and psychotherapists can use historical insights as well as an understanding of basic research rules and psychological theory to identify unconventional treatments other than the ones discussed. The book concludes with a discussion of the advantages and disadvantages of greater regulation of alternative therapies, as compared to the current situation in which few mental health interventions are banned or limited by law.

Selected Books:

book cover
Child Development: Myths and Misunderstandings (Sage, 2nd ed., 2013). Fifty short essays about child development that challenge readers to reconsider pre-conceived notions. For students, the book includes critical thinking questions and examples of research to help make the connection between research designs and conclusions.

book cover
Understanding Attachment: Parenting, Child Care, and Emotional Development (Praeger, 2005). This book provides a concise and jargon-free summary of attachment theory and successfully reveals how developments in the assessment of attachment promoted the evolution of attachment theory to what it is today. It challenges makers of public policy, lawyers and judges, the child care community, and parents to make the effort to truly understand attachment – and to use new knowledge on behalf of all young children and families.

book cover
Attachment Therapy on Trial: The Torture and Death of Candace Newmaker, with Larry W. Sarner & Linda A. Rosa (Praeger, 2003). Candace Newmaker was an adopted girl whose mother felt the child suffered from an emotional disorder that prevented loving attachment. Her adoptive mother, a registered nurse, sought Attachment Therapy, a fringe form of psychotherapy, for the girl and was present at her death by suffocation during that therapy. This text examines the beliefs of the girl’s mother and the  therapists, showing that the death, though unintentional, was a logical outcome of this form of treatment.

  • Jackson family confounds even child-abuse experts,” by Barbara Laker, Philadelphia Daily News, 2003 Dec 2. Dr Mercer has studied a controversial, unorthodox form of therapy – often called attachment therapy – that is used to help build a bond between parents and children. A staunch critic of these methods – which can include food restrictions, holding children so tightly they can’t move, even pinning them to the floor, and forcing them to do meaningless, difficult chores as punishment – Dr Mercer relates how those who adhere to this therapy believe that children form emotional attachments to their parents because they give them food. Food is withdrawn to reinforce parents’ authority. “This is a very cruel and ineffective form of treatment,” Dr Mercer concludes.
