Learning is the way people gain new knowledge, skills, behaviors, or ways of thinking. It can happen through experience, practice, or being taught by someone else. Inside the body, especially the brain, learning changes how brain cells connect and work together. At the same time, learning is also affected by a person’s emotions, surroundings, culture, and social life. This means learning is both a brain-based and a life-based experience.[1][2] In the brain, learning involves tiny changes in the strength of synapses. This is part of a process called neuroplasticity, which means the brain can change and adapt over time.[3] The hippocampus helps form new memories, and the prefrontal cortex helps with attention and making decisions.[4] Chemicals in the brain, called neurotransmitters, like dopamine and acetylcholine, help control motivation, focus, and how we respond to rewards and challenges. These brain parts and chemicals all work together when we learn something new.[5]

There are different types of learning. One type is classical conditioning, where someone learns by connecting two things together, like Pavlov’s dogs learning to expect food when they heard a bell.[6] Another is operant conditioning, where behavior changes based on rewards or punishments, like in B.F. Skinner’s experiments.[7] Observational learning happens by watching others, such as in Bandura’s famous Bobo doll study.[8] There is also latent learning, where someone learns something but does not show it until there is a reason to use it.[9] Some scientists focus on the mental side of learning, like how we remember, think, or understand things. These ideas come from cognitive theories. Piaget believed that people go through stages as they grow and think in more complex ways.[10] Vygotsky said that learning improves when we get help from others, especially when working in our “Zone of Proximal Development”, tasks we can do with guidance but not alone. This shows that learning often depends on talking, working together, and getting support.[11]

Many things affect how well someone learns. These include how motivated they are, what they already know, how they feel, and the way information is taught. Some helpful methods include spaced repetition (reviewing over time) and retrieval practice (trying to recall information), which are more effective than just rereading notes.[12] In the past, people thought learning styles, like being a “visual” or “auditory” learner, were very important, but newer studies show that the way material is organized and how challenging it is matters much more than someone’s preferred learning style.[13] Learning does not only happen in school. Formal learning happens in places like schools and universities. Informal learning happens naturally in everyday life, like when talking to friends or trying a new hobby. Non-formal learning takes place in settings like workshops or online classes, which are structured but not part of traditional school.[14] Adults often learn differently from children. According to Malcolm Knowles’ theory of andragogy, adults prefer learning that is practical, based on their own experiences, and more self-directed.[15]

Technology is also changing how we learn. Tools like educational games, smart tutoring programs, and apps that adjust to your level help make learning more personal and fun.[16] Some programs use ideas from neuroscience, though not all of these are fully proven. Some are based on “neuromyths” or misunderstandings of how the brain works.[17] Also, where and how people grow up affects learning. In group-focused (collectivist) cultures, memorizing facts and respecting teachers might be more common. In more individual-focused cultures, asking questions and thinking critically may be encouraged.[18] Finally, learning is not just something humans do. Many animals also learn. For example, bees can understand the idea of “same” and “different,” and octopuses can solve puzzles.[19][20]

Types

There are a number of different types of learning: [21]

  1. Classical conditioning: where two stimuli come together, the organism learns they are related.
  2. Operant conditioning: an organism changes its behaviour when behaviour has consequences.
  3. Play: an inherited mechanism whereby mammals speed up learning in the young.
  4. Gestalt learning: learning by insight
  5. Imitation, emulation or observational learning: mimicking the behaviour of others
  6. Implicit learning or unconscious learning: learning which is done without conscious awareness of the learning process.
  7. Imprinting: a very rapid type of early learning.

Learning may occur as a result of habituation or classical conditioning, seen in many animal species, or as a result of more complex activities such as play, seen only in relatively intelligent animals.[22][23] Learning may occur consciously or without conscious awareness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early in development.[24] According to James Zull, Professor of Biology and Biochemistry at Case Western University, "Learn­ing is phys­i­cal. Learn­ing means the mod­i­fi­ca­tion, growth, and prun­ing of our neu­rons, connectionscalled synapsesand neu­ronal net­works, through expe­ri­ence".
