Internal working model of attachment
Internal working model of attachment is a psychological approach that attempts to describe the development of mental representations, specifically the worthiness of the self and expectations of others' reactions to the self. This model is a result of interactions with primary caregivers which become internalized, and is therefore an automatic process. John Bowlby implemented this model in his attachment theory in order to explain how infants act in accordance with these mental representations. It is an important aspect of general attachment theory.
Active perception
Active Perception is part of the broader field of ecological psychology. Ecological Psychology (and theories of Ecological Perception) was formulated by gestalt psychologists in the 1930s, and refined by Gibson through the 1950s to 1970s. The theory has held strong, although for the approximately 80 years that it has been around, it has always been considered a niche area of psychology. Ecological Perception has had little traction in medicine, for instance, until recently, when a series of coherent hypotheses proposed that active perception is the basis for developmental disorders and psychiatric symptoms.
