sleep learning

the learning of material presented while one is asleep. The possibility of true sleep learning is still a controversial issue. Simple learning, such as classical conditioning, may occur during sleep; more complex learning, such as the acquisition of a foreign language, has not been reliably demonstrated.

nonadditive

adj. describing values or measurements that cannot be meaningfully summarized through addition because the resulting total does not correctly reflect the underlying properties of and associations between the component values. For example, if two variables a and b interact to influence another variable y, the addition of the separate effects of a and b will not equal the total effect since the contribution of the interaction needs to be included. Compare additive.
