Final answer:
Andi is practicing social referencing, where she looks at her caregivers to understand how to react to the presence of a stranger. It indicates her cognitive and social development during the sensorimotor stage. This behavior is key in learning to navigate social interactions and environments. the correct option is (c).
Step-by-step explanation:
At about 1 year of age, when Andi looks at her caregivers to gauge their reactions when a stranger walks into the room, this phenomenon is called social referencing. This is a process where a child looks to the facial expressions or emotional responses of their caregivers to determine how they should respond to an unfamiliar event or person. It is different from stranger anxiety, which refers to the fear of unfamiliar people, and separation anxiety, which involves distress when a caregiver leaves. Social referencing is an important part of children's social and emotional development and helps them learn to understand and navigate their environment.
Mary Ainsworth's research using the Strange Situation procedure illustrates various forms of attachment and reactions to strangers and separation. This research helps detail the behaviors that manifest at these stages of development, including social referencing. Object permanence, on the other hand, is the understanding that objects continue to exist even when they're out of sight.
