- AThe caregiver is being used as a secure base for exploration and reassurance.correct
- BThe toddler has completed formal operational reasoning.
- CThe toddler has learned language only through imitation of adult grammar.
- DThe stranger has become an unconditioned stimulus.
Why A is correct
The behavior shows exploration balanced with caregiver reassurance.
secure attachment explains the evidence in "A toddler explores a playroom while a caregiver sits nearby.". The credited option, "The caregiver is being used as a secure base for exploration and reassurance", is supported because Exploring while returning for comfort is consistent with secure attachment behavior. "The toddler has learned language only through imitation of adult grammar" is a real-looking alternative, but The observation is about attachment, not language learning; "The stranger has become an unconditioned stimulus" also fails because The stranger may be new, but the scenario does not make the stranger an unconditioned stimulus. The aim is to connect the concrete evidence to the psychological mechanism, then reject choices that shift the process, time frame, or research logic away from the scenario pattern.
