Explanation:
The theorist who believed that children learn language when they are reinforced by parental attention was B.F.Skinner.
B.F.Skinner was a celebrated American psychologist who advanced the behaviorist theory of learning. This theory is based on the idea that learning occurs through a method of ‘conditioning’, which when stimulus, rewards, and punishments are combined to drive the learning process.
The conditioning relies on what Skinner calls reinforcement. Reinforcement is of two types, namely positive reinforcers, which are the rewards after meeting a target, and negative reinforcers, which refers to the unpleasant consequences of failing to meet the target.
Actions that are followed by negative reinforcers tend to weaken, while those followed by positive reinforcers tend to be repeated. For example, children can be encouraged to learn language if they receive consistent positive reinforcement from their parents every time they learn a new word or phrase.
