In a contemporary replication of Harlow's surrogate-mother paradigm, infant macaques are housed with two artificial mothers: a wire frame dispensing milk and a cloth-covered frame providing no food. Researchers record clinging time, and they introduce a startling mechanical spider to assess where the infant flees.
When the cloth mother is present, infants explore a novel toy more often than when she is absent. This pattern best illustrates:

Use of an attachment figure as a secure base for exploration
- B
Object permanence
- C
Stranger anxiety
- D
Imprinting in the Lorenz sense
Explanation
Bowlby and Ainsworth describe attachment figures as a 'secure base' that supports exploration—exactly what Harlow's monkeys demonstrated with the cloth surrogate.
