Final answer:
Latent learning refers to knowledge acquired and retained without being immediately apparent, only revealing itself when it is necessary to use it.
Step-by-step explanation:
Learning that does not reveal itself until it is needed is called latent learning. Latent learning refers to knowledge acquired and retained without being immediately apparent, only revealing itself when it is necessary to use it. An example of latent learning is when a child like Ravi learns the route to school by observing his dad drive but doesn't demonstrate this knowledge until he rides his bike to school by himself when his dad is unavailable. This is a hallmark of latent learning, where knowledge is acquired and retained until a situation necessitates its use, without the learning being immediately evident.
