Trauma in Attachment: Understanding the First Relationship Through Neurobiology and Psychodynamics

Much has been elucidated about the neurobiological effects of early childhood trauma and its transgenerational transmission, although its integration into psychodynamic therapy has been challenging. Here we focus on a common area of interest to both areas-emotion and cognition rooted in past trauma experiences and how these experiences produce maladaptive behaviors transmitted to the next generation through parenting behaviors. We explore two mammalian research paradigms of early-life trauma explicitly within attachment, and transmission of transgenerational pathology through the caregiver to the offspring. We suggest that understanding the neurobiology through this mammalian nonhuman research can provide, in part, an understanding for the complex psychodynamic thought processes seen in adulthood, particularly as the mother begins to raise her own child. Specifically, while cognition and complex conscious and unconscious thoughts are characteristic of the human condition following early-life trauma, the mother-infant attachment system is a phylogenetically preserved system with some basic characteristics seen across species. We outline how embracing both the cognition and preserved trauma neural programing within attachment may provide some insight into cases, especially for the parent-child social interactions well documented to program the brain. Using mother-infant attachment, we suggest there is an area of convergence between clinical psychodynamic focus and basic research in brain function and mechanisms. Focusing on this convergence may provide a unique viewpoint to psychodynamics to supplement diagnosis and treatment.
