Implications of recent research in neurobiology for psychological assessment

In this article, I highlight 3 major findings from current research in attachment, neurobiology, psychopathology, and psychotherapy: (a) attachment failures and early trauma are related to many forms of psychopathology, (b) one of the major sequelae of developmental trauma is disorganization of the right hemisphere, and (c) psychological interventions that promote emotional experience, awareness, and expression are more effective than those that rely solely on cognitive restructuring. I then suggest implications of these findings for the practice of psychological assessment: (a) the relationship between client and assessor is more important than has been acknowledged generally, (b) performance-based personality tests are very useful in part because they tap right-hemisphere and subcortical brain functioning and provide information that clients cannot directly report, and (c) when psychological assessments provide clients with powerful emotional experiences, therapeutic change is often the result. I illustrate these points with excerpts from the Therapeutic Assessment of a 27-year-old man with compulsive sexual behavior.
