of the development of personality via linear phases with regression to fixed points accounting for psychological distress. Bowlby instead posited that several lines of development were possible, the outcome of which depended on the interaction between the organism and the environment. In attachment this would mean that although a developing child has a propensity to form attachments, the nature of those attachments depends on the environment to which the child is exposed. From early in the development of attachment theory there was criticism of the theory's lack of congruence with various branches of psychoanalysis. Bowlby's decisions left him open to criticism from well-established thinkers working on similar problems. Internal working model The philosopher Kenneth Craik had noted the ability of thought to predict events. He stressed the survival value of natural selection for this ability. A key component of attachment theory is the attachment behaviour system where certain behaviours have a predictable outcome (i.e. proximity) and serve as self-preservation method (i.e. protection). All taking place outside of an individuals awareness, This internal working model allows a person to try out alternatives mentally, using knowledge of the past while responding to the present and future. Bowlby applied Craik's ideas to attachment, when other psychologists were applying these concepts to adult perception and cognition. Infants absorb all sorts of complex social-emotional information from the social interactions that they observe. They notice the helpful and hindering behaviours of one person to another. From these observations they develop expectations of how two characters should behave, known as a "secure base script." These scripts provide as a template of how attachment related events should unfold and they are the building blocks of ones internal working models. infant's internal working model is developed in response to the infant's experience based internal working models of self, and environment, with emphasis on the caregiving environment and the outcomes of his or her proximity-seeking behaviours. Theoretically, secure child and adult script, would allow for an attachment situation where one person successfully utilizes another as a secure base from which to explore and as a safe haven in times of distress. In contrast, insecure individuals would create attachment situations with more complications. For example, If the caregiver is accepting of these proximity-seeking behaviours and grants access, the infant develops a secure organization; if the caregiver consistently denies the infant access, an avoidant organization develops; and if the caregiver inconsistently grants
