Myron Arms Hofer

Last updated

Myron Arms Hofer (born December 20, 1931) is an American psychiatrist and research scientist, currently Sackler Institute Professor Emeritus in the Department of Psychiatry at Columbia University College of Physicians & Surgeons. He is known for his research on basic developmental processes at work within the mother-infant relationship. Using animal models, he found unexpected neurobiological and behavioral regulatory processes within the observable interactions of the infant rat and its mother. Through an experimental analysis of these sensorimotor, thermal and nutrient-based processes, he has contributed to our understanding of the impact of early maternal separation, the origins of the attachment system, and the shaping of later development by variations in how mothers and infants interact.

Early life

Born in New York City, Hofer’s family moved to Cambridge, Massachusetts in 1939 when his father, Philip Hofer, became curator of the Department of Printing and Graphic Arts at Harvard's newly built Houghton Library. Hofer went to school and college in the Boston area and married in 1954. His wife, Lynne, co-founded the Young Filmaker's Foundation and later became a psychoanalyst. The Hofers have three children and eight grandchildren.

Career path

Hofer graduated from Harvard College and Harvard Medical School (MD 1958), did his residency training in Medicine at Massachusetts General Hospital and in Psychiatry at New York State Psychiatric Institute, followed by post-doctoral research at the National Institute of Mental Health (NIMH) and the American Museum of Natural History, before joining the department of psychiatry at Albert Einstein College of Medicine in 1966, where he began his animal model research. In 1984, Hofer moved with his research group to the Department of Psychiatry at Columbia University College of Physicians and Surgeons, and in 2000 was appointed Director of the Sackler Institute for Developmental Psychobiology.

Following his early clinical research as member of the NIMH group studying threatened loss and bereavement in the parents of children with leukemia, [4] Hofer turned to animal model research to study the biological basis for the impact of separation and loss in a typical laboratory mammal. He described widespread bio-behavioral effects in infant rats during the hours after separation from their mothers, and defined the mechanisms for these effects as withdrawal (i.e. loss) of numerous unexpected regulators of infant physiology and behavior that he found within the sensorimotor, thermal and nutrient-based interactions between mothers and their infants. The discovery of these “hidden regulators” added a new dimension to the concept of early attachment. [5] [6] Hofer and his colleagues [7] went on to study infant behaviors that initiate and maintain proximity to the mother and mediate complex interactions such as nursing, and sleep-wake state regulation, [8] and showed that altering the patterns and types of interactions between mothers and infants caused short and long-term changes in offspring development, and biological vulnerability, extending into adulthood, even into the next generation. [9] [10] These studies provided clues and ideas that have guided subsequent research on human mother-infant attachment behaviors, [11] and clinical research and thinking about human bereavement. [12] Subsequent research led to an animal model for studying the development of anxiety, extending from childhood separation sensitivity to adult anxiety disorder. Hofer and colleagues explored how the ultrasonic isolation calling response of the infant rat [13] is regulated at the sensory, behavioral and neurochemical levels. [14] He then used selective breeding for high and for low levels of the infant trait, as a model for studying evolution and how it can interact with developmental processes in the creation of differences in adult temperament. [15] Hofer’s research and its implications have been periodically reported in the Science section of the N.Y. Times. [16] [17] [18] [19] He has served on the National Academy of Medicine committee on the management of the consequences of bereavement. [20] and later on the national advisory committee for development of the Healthy Steps for Young Children Program that has been effective in applying new treatment principles in Pediatrics for mothers and young children. He was asked to write the entry on "Development, psychobiology" for the “Encyclopedia of Human Biology”, edited by Renato Dulbecco, [21] and has recently contributed invited chapters on his research and thinking about development, for Handbooks in the fields of attachment, developmental and cognitive neuroscience, mammalian vocalization and anxiety disorders.

Awards and honors

Hofer was elected president of the International Society for Developmental Psychobiology, and the American Psychosomatic Society, and to membership in the Academy of Behavioral Medicine Research. His awards include the Thomas William Salmon Memorial Lectures, [27] the Senior Investigator Award of the International Society for Developmental Psychobiology, and the Paul Hoch Award, presented at the 2012 meeting of the American Psychopathological Association. An issue of Developmental Psychobiology (journal), was published in 2005 in recognition of his contributions to the field. [28]

Co-sleeping or bed sharing is a practice in which babies and young children sleep close to one or both parents, as opposed to in a separate room. Co-sleeping individuals sleep in sensory proximity to one another, where the individual senses the presence of others. This sensory proximity can either be triggered by touch, smell, taste, or noise. Therefore, the individuals can be a few centimeters away or on the other side of the room and still have an effect on the other. It is standard practice in many parts of the world, and is practiced by a significant minority in countries where cribs are also used.

Attachment disorder is a broad term intended to describe disorders of mood, behavior, and social relationships arising from unavailability of normal socializing care and attention from primary caregiving figures in early childhood. Such a failure would result from unusual early experiences of neglect, abuse, abrupt separation from caregivers between three months and three years of age, frequent change or excessive numbers of caregivers, or lack of caregiver responsiveness to child communicative efforts resulting in a lack of basic trust. A problematic history of social relationships occurring after about age three may be distressing to a child, but does not result in attachment disorder.

Attachment theory is a psychological and evolutionary framework concerning the relationships between humans, particularly the importance of early bonds between infants and their primary caregivers. Developed by psychiatrist and psychoanalyst John Bowlby (1907–90), the theory posits that infants need to form a close relationship with at least one primary caregiver to ensure their survival, and to develop healthy social and emotional functioning.

Edward John Mostyn Bowlby, CBE, FBA, FRCP, FRCPsych was a British psychiatrist, and psychoanalyst, notable for his interest in child development and for his pioneering work in attachment theory. A Review of General Psychology survey, published in 2002, ranked Bowlby as the 49th most cited psychologist of the 20th century.

Rachel Barr is a professor at Georgetown University. She is currently the co-director of graduate studies in the Department of Psychology at Georgetown University. Her research focuses on understanding the learning and memory mechanisms that develop during infancy. Because infants are preverbal, her techniques rely on imitation and learning methods to find out what infants have learned and how well and how long they remember it. Her previous research has focused on how infants pick up information from different media sources, television, siblings, adults, and different contexts. Most recently, Barr's studies focus on factors that might enhance infant learning from television.

<span class="mw-page-title-main">Attachment in children</span> Biological instinct

Attachment in children is "a biological instinct in which proximity to an attachment figure is sought when the child senses or perceives threat or discomfort. Attachment behaviour anticipates a response by the attachment figure which will remove threat or discomfort". Attachment also describes the function of availability, which is the degree to which the authoritative figure is responsive to the child's needs and shares communication with them. Childhood attachment can define characteristics that will shape the child's sense of self, their forms of emotion-regulation, and how they carry out relationships with others. Attachment is found in all mammals to some degree, especially primates.

Attachment measures, or attachment assessments, are the various procedures used to assess the attachment system in children and adults. These procedures can assess patterns of attachment and individual self-protective strategies. Some assessments work across the several models of attachment and some are model-specific. Many assessments allow children and adults' attachment strategies to be classified into three primary attachment pattern groups: B-pattern, A-pattern, C-pattern. In most models, each pattern group is further broken down into several sub-patterns. Some assessments are capable of finding additional information about an individual, such as unresolved trauma, depression, history of family triangulation, and lifespan changes in the attachment pattern. Some assessments specifically or additionally look for caregiving behaviors, as caregiving and attachment are widely considered two separate systems for organizing thoughts, feelings, and behavior. Some methods assess disorders of attachment or romantic attachment.

Co-regulation is a term used in psychology. It is defined most broadly as a "continuous unfolding of individual action that is susceptible to being continuously modified by the continuously changing actions of the partner". An important aspect of this idea is that co-regulation cannot be reduced down to the behaviors or experiences of the individuals involved in the interaction. The interaction is a result of each participant repeatedly regulating the behavior of the other. It is a continuous and dynamic process, rather than the exchange of discrete information.

Developmental psychobiology is an interdisciplinary field, encompassing developmental psychology, biological psychology, neuroscience and many other areas of biology. The field covers all phases of ontogeny, with particular emphasis on prenatal, perinatal and early childhood development. Conducting research into basic aspects of development, for example, the development of infant attachment, sleep, eating, thermoregulation, learning, attention and acquisition of language occupies most developmental psychobiologists. At the same time, they are actively engaged in research on applied problems such as sudden infant death syndrome, the development and care of the preterm infant, autism, and the effects of various prenatal insults on the development of brain and behavior.

Daniel S. Schechter is an American and Swiss psychiatrist known for his clinical work and research on intergenerational transmission or "communication" of violent trauma and related psychopathology involving parents and very young children. His published work in this area following the terrorist attacks on the World Trade Center in New York of September 11, 2001 led to a co-edited book entitled "September 11: Trauma and Human Bonds" (2003) and additional original articles with clinical psychologist Susan Coates that were translated into multiple languages and remain among the first accounts of 9/11 related loss and trauma described by mental health professionals who also experienced the attacks and their aftermath Schechter observed that separation anxiety among infants and young children who had either lost or feared loss of their caregivers triggered posttraumatic stress symptoms in the surviving caregivers. These observations validated his prior work on the adverse impact of family violence on the early parent-child relationship, formative social-emotional development and related attachment disturbances involving mutual dysregulation of emotion and arousal. This body of work on trauma and attachment has been cited by prominent authors in the attachment theory, psychological trauma, developmental psychobiology and neuroscience literatures

<span class="mw-page-title-main">Maternal sensitivity</span>

Maternal sensitivity is a mother's ability to perceive and infer the meaning behind her infant's behavioural signals, and to respond to them promptly and appropriately. Maternal sensitivity affects child development at all stages through life, from infancy, all the way to adulthood. In general, more sensitive mothers have healthier, more socially and cognitively developed children than those who are not as sensitive. Also, maternal sensitivity has been found to affect the person psychologically even as an adult. Adults who experienced high maternal sensitivity during their childhood were found to be more secure than those who experienced less sensitive mothers. Once the adult becomes a parent themselves, their own understanding of maternal sensitivity will affect their own children's development. Some research suggests that adult mothers display more maternal sensitivity than adolescent mothers who may in turn have children with a lower IQ and reading level than children of adult mothers.

<span class="mw-page-title-main">Parental brain</span>

Parental experience, as well as changing hormone levels during pregnancy and postpartum, cause changes in the parental brain. Displaying maternal sensitivity towards infant cues, processing those cues and being motivated to engage socially with her infant and attend to the infant's needs in any context could be described as mothering behavior and is regulated by many systems in the maternal brain. Research has shown that hormones such as oxytocin, prolactin, estradiol and progesterone are essential for the onset and the maintenance of maternal behavior in rats, and other mammals as well. Mothering behavior has also been classified within the basic drives.

Separation anxiety disorder (SAD) is an anxiety disorder in which an individual experiences excessive anxiety regarding separation from home and/or from people to whom the individual has a strong emotional attachment. Separation anxiety is a natural part of the developmental process. It is most common in infants and little children, typically between the ages of six to seven months to three years, although it may pathologically manifest itself in older children, adolescents and adults. Unlike SAD, normal separation anxiety indicates healthy advancements in a child's cognitive maturation and should not be considered a developing behavioral problem.

Emotional abandonment is a subjective emotional state in which people feel undesired, left behind, insecure, or discarded. People experiencing emotional abandonment may feel at a loss. They may feel like they have been cut off from a crucial source of sustenance or feel withdrawn, either suddenly or through a process of erosion. Emotional abandonment can manifest through loss or separation from a loved one.

<span class="mw-page-title-main">Ultrasonic vocalization</span>

Ultrasonic vocalizations (USVs) occur at frequencies ranging from approximately 20–100 kHz. They are emitted by animals such as bats and rodents, and have been extensively studied in rats and mice. As opposed to sonic vocalizations, ultrasonic vocalizations cannot be detected by the human ear. USVs serve as social signals, and are categorized according to their frequency. Different categories of USVs are elicited in response to different situations and varying affective states. The behavioural functions of USVs vary as a rat or mouse pup reaches the juvenile/adult stage of their development. The brain mechanisms behind calling behaviour have also been studied, and some studies have used pharmacological manipulation.
