Which researcher stated that babies can learn and remember that foot movement moves the mobile?

• A. Rovee-Collier
• B. Gibson and Walk
• C. Rader et al
• D. Halo Effect

Answer: (A)

This question tests how infants can learn that their own actions cause a consequence and remember that link over time. The classic demonstration of this idea is Carolee Rovée-Collier’s mobile conjugate reinforcement studies. In that setup, an infant wears a ribbon tied to a mobile; when the infant kicks, the movement of the leg makes the mobile rotate. The infant learns this contingency, and with a short delay can continue to kick to make the mobile move, showing both learning and memory for the action–outcome relationship even before language develops. That’s why Rovée-Collier is the best match. The other names are associated with different topics: Gibson and Walk studied depth perception with the visual cliff; Rader and colleagues aren’t the standard reference for this infant contingency memory; the Halo Effect refers to a social-psychology bias.
