These are assessed using the Strange Situation Procedure, designed to assess the quality of attachments rather than whether an attachment exists at all.A securely attached toddler will explore freely while the caregiver is present, engage with strangers, be visibly upset when the caregiver departs, and happy to see the caregiver return. The anxious-ambivalent toddler is anxious of exploration, extremely distressed when the caregiver departs but ambivalent when the caregiver returns. The anxious-avoidant toddler will not explore much, avoid or ignore the parent—showing little emotion when the parent departs or returns—and treat strangers much the same as caregivers with little emotional range shown. The disorganized/disoriented toddler shows a lack of a coherent style or pattern for coping. Evidence suggests this occurs when the caregiving figure is also an object of fear, thus putting the child in an irresolvable situation regarding approach and avoidance. On reunion with the caregiver, these children can look dazed or frightened, freezing in place, backing toward the caregiver or approaching with head sharply averted, or showing other behaviors implying fear of the person who is being sought. It is thought to represent a breakdown of an inchoate attachment strategy and it appears to affect the capacity to regulate emotions.Although there are a wide range of attachment difficulties within the styles which may result in emotional disturbance and increase the risk of later psychopathologies, particularly the disorganized style, none of the styles constitute a disorder in themselves and none equate to criteria for RAD as such.
Low-set ears are a clinical feature in which the ears are positioned lower on the head than usual. They are present in many congenital conditions. Low-set ears are defined as outer ears positioned two or more standard deviations lower than the population average. Clinically, if the point at which the helix of the outer ear meets the cranium is at or below the line connecting the inner canthi of eyes(bicanthal plane), the ears are considered low set.Low-set ears can be associated with conditions such as:

Down syndrome
Turner syndrome
Noonan syndrome
Patau syndrome
DiGeorge syndrome
Cri du chat syndrome
Edwards syndrome
Fragile X syndrome
Okamoto syndromeIt is usually bilateral, but it can be unilateral in Goldenhar syndrome. See also
LEOPARD syndrome
