In 1951, Karl Lashley, a neurophysiologist at Harvard University, published “The Problem of Serial Order in Behavior,” addressing the current beliefs about sequence learning and introducing his hypothesis.
The next line is the properties of movements occurring early in a sequence can anticipate later features.
A second line of evidence says that errors are involved in human behavior as hierarchical organization.
However, recently, implicit sequence learning has gained more attention and research.
The exact properties and number of mechanisms of implicit learning are debated.
Sequential decision making or sequence generation through actions breaks down into three variations: goal-oriented, trajectory-oriented, and reinforcement-maximizing.
In a classic experiment published in 1967, Alfred L. Yarbus demonstrated that though subjects viewing portraits reported apprehending the portrait as a whole, their eye movements successively fixated on the most informative parts of the image.
Thus, it appears that a neural code or representation for the learned skill is created in our brain, which is usually called procedural memory.
How humans learn sequential procedures has been a long-standing research problem in cognitive science and currently is a major topic in neuroscience.
Research work has been going on in several disciplines, including artificial intelligence, neural networks, and engineering.
