Working memory vs STM

Working memory vs STM

1. Introduced by Baddeley and Hitch (1974)

   • Def.: “a limited-capacity system for temporary storage and manipulation of information for complex tasks such as comprehension, learning, and reasoning.”
     • Capacité limité
       • Stockage temporaire de l'info
     • VS ancien modèle de la mémoire à court terme (STM)
       • Manipulation de l'info
         • Pour tâches complexes
           • Compréhension
           • Apprentissage
           • Raisonnement
       • ''Atkinson and Shiffrin’s modal model''
         • 1 tâche à la fois
           • occupy the entire STM.

2. Holding + processing infos

   • active (dynamic) processes
     • ex. understanding conversations
     • ex. solving (even simple) math problems

3. Possibility to carry out two tasks simultaneously

4. consist of a number of components

   • can function separately
