Attachment theory is a psychological, evolutionary and ethological theory concerning relationships between humans. The most important tenet is that young children need to develop a relationship with at least one primary caregiver for normal social and emotional development. The theory was formulated by psychiatrist and psychoanalyst John Bowlby.
Evolutionary developmental psychology (EDP) is a research paradigm that applies the basic principles of evolution by natural selection, to understand the development of human behavior and cognition. It involves the study of both the genetic and environmental mechanisms that underlie the development of social and cognitive competencies, as well as the epigenetic processes that adapt these competencies to local conditions.
Lyn Yvonne Abramson is a professor of psychology at the University of Wisconsin–Madison. She was born in Benson, Minnesota. She took her undergraduate degree at the University of Wisconsin–Madison in 1972 before attaining her Ph.D. in clinical psychology at University of Pennsylvania in 1978.
Socio-ecological models were developed to further the understanding of the dynamic interrelations among various personal and environmental factors. Socioecological models were introduced to urban studies by sociologists associated with the Chicago School after the First World War as a reaction to the narrow scope of most research conducted by developmental psychologists. These models bridge the gap between behavioral theories that focus on small settings and anthropological theories.
Carroll Ellis Izard was an American research psychologist known for his contributions to differential emotions theory (DET), and the Maximally Discriminative Affect Coding System (MAX) on which he worked with Paul Ekman. Izard also undertook empirical studies into the facial feedback hypothesis according to which emotions which have different functions also cause facial expressions which in turn provide us with cues about what emotion a person is feeling. In addition, Izard constructed a multidimensional self-report measure – the Differential Emotions Scale – currently in its 4th edition (DES-IV). His later research focused on emotional development in young children and the development and testing of his Emotions Course for Young Children.
Emotional self-regulation or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. Emotional self-regulation belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.

Attachment-based therapy applies to interventions or approaches based on attachment theory, originated by John Bowlby. These range from individual therapeutic approaches to public health programs to interventions specifically designed for foster carers. Although attachment theory has become a major scientific theory of socioemotional development with one of the broadest, deepest research lines in modern psychology, attachment theory has, until recently, been less clinically applied than theories with far less empirical support. This may be partly due to lack of attention paid to clinical application by Bowlby himself and partly due to broader meanings of the word 'attachment' used amongst practitioners. It may also be partly due to the mistaken association of attachment theory with the pseudo-scientific interventions misleadingly known as attachment therapy. The approaches set out below are examples of recent clinical applications of attachment theory by mainstream attachment theorists and clinicians and are aimed at infants or children who have developed or are at risk of developing less desirable, insecure attachment styles or an attachment disorder.
Mary Main was an American psychologist notable for her work in the field of attachment. A Professor at the University of California Berkeley, Main is particularly known for her introduction of the 'disorganized' infant attachment classification and for development of the Adult Attachment Interview and coding system for assessing states of mind regarding attachment. This work has been described as 'revolutionary' and Main has been described as having 'unprecedented resonance and influence' in the field of psychology.

Vittorio Filippo Guidano was an Italian neuropsychiatrist, creator of the cognitive procedural systemic model and contributor to constructivist post-rationalist cognitive therapy. His cognitive post-rationalist model was influenced by attachment theory, evolutionary epistemology, complex systems theory, and the prevalence of abstract mental processes proposed by Friedrich Hayek. Guidano conceived the personal system as a self-organized entity, in constant development.
