SPEED Model Applications
SPEEDAn Contrarian Model of Procedural Expertise
Previous Notions
“It has been widely held that although memory traces are at first formed in the cerebral cortex, they are finally reduced or transferred by long practice to subcortical levels” (p. 466)
Karl Lashley (1950) In search of the engram.
Previous Notions
“Routine, automatic, or overlearned behavioral sequences, however complex, do not engage the PFC and may be entirely organized in subcortical structures” (p. 323)
Joaquin Fuster (2001). The prefrontal cortex – an update.
SPEEDAn Contrarian Model of Procedural Expertise
SPEED Model
Procedural learning is striatum dependent.
Procedural expertise is striatum independent.
