One-year-old Beth will explore a room when her mother is present.She becomes upset when her mother leaves the room and is quickly calmed when her mother returns.What is the term used for this type of methodology if Beth is in a study where this pattern is repeated several times,while a researcher records Beth's response

A)  avoidance procedure
B)  inhibition evaluation 
C)  temperament test
D)  strange situation

The scenario described is the classic Strange Situation test, which is a well-known laboratory procedure used to evaluate an infant's attachment style. In this test, the child is observed in a playroom with their caregiver, a stranger, and without the caregiver. The caregiver leaves the room twice, and the child's response to their absence and return is recorded. Beth's behavior of exploring while the mother is present, getting upset when the mother leaves, and being calmed when the mother returns matches the pattern observed in babies with a secure attachment style. Thus, the best choice here is D- strange situation.
