- Sequence learning
Serial organization is fundamental to human
behaviour . Most of our day-to-day activities involve sequencing of actions to achieve a desired goal, from sequencing words toform a sentence, to driving an automobile or following directions on a roadmap, to making a recipe following instructions in a cooking manual (see Sun and Giles 2001). Lashley (1951) has highlighted the ubiquity of sequentiality or serial order in our behaviour“ ... the coordination of leg movements in insects, the song of birds, the control oftrotting and pacing in a gaited horse, the rat running the maze, the architectdesigning a house, the carpenter sawing a board present a problem of sequencesof action ... ”
In a classic experiment,
Yarbus (1967) demonstrated that though the subjects viewing portraits report to apprehend the portrait as a whole, their eye movements successively fixated at the most informative parts of the image. These observations suggest that underlying an apparently parallel process of face perception, a serialoculomotor process is concealed. It is a common observation that when askill is being acquired, we are more attentive in the initial phase, but after repeated practice, the skill becomes nearly automatic (Fitts, 1964), this is also known asunconscious competence . We can then concentrate onlearning a new action while performing previously learned actions skillfully. Thus it appears that a neural code or representation for the learnt skill is created in our brain, which is usually calledprocedural memory . The procedural memory encodes procedures or algorithms rather than facts.There are many other areas of application for sequence learning. Researchwork on sequence learning has been going on in several disciplines such as
artificial intelligence ,neural networks ,cognitive science (sequence learning aspectsin skill acquisition), and engineering [cite paper|author=Ron Sun and C. Lee Giles|title=Sequence Learning: From Recognition and Prediction to Sequential Decision Making|date=Aug 2001|url=http://www.cogsci.rpi.edu/~rsun/sun.expert01.pdf|accessdate=2007-05-05] . How humans learn sequential procedureshas been a long-standing research problem incognitive science and currently isa major topic inneuroscience .References
