Sequence Learning and Serial Reaction-Time Task
Why Sequence Learning?
All complex behaviours are built from a limited number of simpler behavioural elements.
Known as
motor primites
,
motor quanta
,
functional synergies
.
Motor Primitives
A building component of body movements, usually consisting of coordinated kinematic variables (i.e., joint angels) or dynamic variables (i.e., muscle activations).
Speech
As a motor process, speaking is an intricate orchestration of multiple
effectors
(articulators) corrdinated in time and space to produce sound sequences.
When Motor Sequences Go Wrong
Stuttering
Effects 1% of adults
Dyspraxia
Effects 10% of children - 2% severely.
Focal Dystonia
Musicians, artists, sports (yips)
Brain Damage
Sequence Learning is Important
The ability to learn, remember and produce these learnt sequences at will, underpin many activities in daily life.
This skill allows us to go about our daily life without having to use up out brains processing power to perform the mindane tasks.
If this ability is compromised - it can have profound results.
Therefore, understanding sequence learning is important.
The Science of Sequence Learning

The Problem of Serial Order in Behaviour
Suggested a cognitive account in which behaviour sequences are typically controlled with
central plans
