Acquisition refers to the process of grasping information by the subconscious mind without the conscious mind being aware. Learning refers to the conscious process of obtaining knowledge. When used together, acquisition learning works in the case of native languages, which usually a child learns while growing up. A child’s brain pairs audio with actions, to store words and their implied meanings in the subconscious mind.
Stephen Krashen gave the theory of Language Acquisition, in which he argued that the first language acquired in the home environment is always native, and the second language is always learned through cognitive ability. The second language is a product of formal teaching on grammar and the style of the language.
The information about the native language stored in the brain through communication in the child’s early growing years is known as acquisition learning. There is no formal training, and the focus is more on the text rather than the style and grammar. There are different learning styles for students. Though acquisition learning is not a type of learning, it can be considered as a branch of the same.
The first language that most of the people speak is through acquisition learning without any formal training. Human babies start speaking as early as one year of age before they go to any school for formal education.
