In this article I would like to describe the Bird's Nest Drawing technique. It was developed by Donna Kaiser, Ph.D., certified art therapist, assistant professor of psychology at Albertus Magnus College in New York. -Haven (Connecticut), Director of Research, Department of Art Therapy, Eastern Virginia Medical University (Norfolk, Virginia). This technique was developed for the level of attachment assessment. Research was conducted over ten years in various groups of subjects. Unlike other art therapeutic techniques, the “Drawing a Bird's Nest” technique is based on attachment theory and evaluates a person’s internalized view of himself and others. Interiorization (from French interiorization - transition from outside to inside and Lat. Interior - internal) - the formation of internal structures of the human psyche through the assimilation of external social activities, the appropriation of life experience, the formation of mental functions and development in general. Attachment theory Attachment theory has the basis for the study of human development and relationships and is associated with psychoanalytic ideas. The founder of attachment theory is John Bowlby. In his theory, he focused on how important attachment is throughout a person's life. Babies instinctively feel the need to be close to adults who care for them. At any age, a person feels very happy and confident and develops most fully as a person when he is confident that one or more close people are behind him. Such confidence serves as support and protection, which allows you to take more risky steps towards achieving your goal. This experience is acquired from the first minutes of life. Based on early experience of communicating with parents, children develop an internal model of behavior for interacting with other people and the outside world in general. This model of behavior includes a person’s idea of ​​both himself and the world as a whole: is he worthy of being loved and cared for? The internal model of behavior is the basis for building relationships throughout a person’s life. Research has identified three types of attachment disorders in children: evasive (avoidant), ambivalent (stubborn-resistant), disorganized (disoriented). In adults, these attachment disorders are associated with neglect, preoccupation and anxiety. People with attachment disorders have a variety of problems with emotion regulation. More often than others, they tend to deny emotions, or, on the contrary, to express them too violently and not control them at all. Art therapy and attachment theory For art therapists, the work of Kaplan and Main (1986), who studied children’s drawings with images of their attachment figures, is of great interest. The work used drawings by preschool children depicting family members. As a result of the research, signs were developed that, with a 76% probability, indicate insecure attachments. Children with secure attachment in their drawings depicted different emotions in different family members, all members were located at a fairly close distance, they interacted with each other. Children with avoidant disorder portrayed family members with identical happy facial expressions (superficial, false image), and the figures often lacked arms, legs, or other important body parts. Children with ambivalent attachment depicted either too small or too large figures, often the figures were layered on top of each other, the figures of the parents occupied most of the sheet, some parts of the body were very enlarged. Children with disorganized attachment were similar to the previous images, but there were deformations and irrational images of figures, unfinished images. Drawing a bird's nest This projective technique was developed.).
