The "Strange Situation"
The "strange situation" is a laboratory procedure used to assess infant attachment style. The procedure consists of the following eight episodes (Connell & Goldsmith, 1982; Ainsworth, Blehar, Waters, & Wall, 1978).
- Parent and infant are introduced to the experimental room.
- Parent and infant are alone. Parent does not participate while infant explores.
- Stranger enters, converses with parent, then approaches infant. Parent leaves inconspicuously.
- First separation episode: Stranger's behavior is geared to that of infant.
- First reunion episode: Parent greets and comforts infant, then leaves again.
- Second separation episode: Infant is alone.
- Continuation of second separation episode: Stranger enters and gears behavior to that of infant.
- Second reunion episode: Parent enters, greets infant, and picks up infant; stranger leaves inconspicuously.
The infant's behavior upon the parent's return is the basis for classifying the infant into one of three attachment categories.
