People with secure attachment styles, are capable of using their caregivers as a basis of safety when they are distressed. They have caregivers who are sensitive to their needs, therefore, have confidence that their attachment figures will be available, which will respond and help them in the face of adversity. (Feeney, B. & Kirkpatrick, l. 1996). In the interpersonal domain, secure people tend to be more warm, stable and satisfactory intimate relationships, and intrapersonal domain, tend to be more positive, integrated and coherent perspective of himself.

(Mikulincer, M. 1998a). 2. Persons with evasive attachment styles, exhibit an apparent selflessness and detachment to the presence of their caregivers during periods of distress. These children have little confidence that will be helped and expect to be displaced because thus past experiences tell it. (Feeney, B. & Kirkpatrick, l. 1996).

These people possess insecurity towards others and prefer to keep apart from the others, in addition, have fear of intimacy and show have difficulty relying on people. (Mikulincer, M. 1998b). 3. Children with ansioso-ambivalente attachment style, respond to the separation with intense anguish and mixed behaviors of attachment with expressions of protest, anger and resistance. Due to the inconsistency in the emotional skills of their caregivers, these children have no expectations of confidence with respect to access to and response from their caregivers (Feeney, B. & Kirkpatrick, l. 1996). These people are defined by a strong desire for intimacy, along with one insecurity with respect to each other. (Mikulincer, M. 1998b). Scopes, impact studies they have examined the hypothesis that people with different attachment styles differ in the way of searching and processing information. This hypothesis is based on the own postulates of Bowlby which holds that models of attachment affect the encoding and organizing information about emotional events, figures of attachment and the self. (Mikulincer, M. 1997). It is said that based on these postulates are studies about the differences between styles of attachment in adults and the search for new information, understood as the exploration of the environment and the acquisition of knowledge about things unknown as places, people and objects; and the integration of new information into the cognitive structures consisting of decode information acquired, comparing it to the existing information and arranging the scheme to new information (Mikulincer, M. 1997). It has been found that people with secure attachment style carried out an active search for information, being open to new information and they have flexible cognitive structures, as they can deal well with anguish, they are able to incorporate new information, even if you move them to momentary confusion periods, because they are able to reorganize their schemas. This capability would lead them to adjust adequately to changes in the environment, set realistic goals and to avoid irrational beliefs. People with evasive attachment style, reject information that could create confusion, closing their schemes to this, having rigid cognitive structures. Ansiosas-ambivalentes people also show this behavior, but unlike the avoiders, want access to new information, but their intense conflicts take them away from her (Mikulincer, M. 1997).
