19 Short-term memory is limited

1. Working memory and focused attention

   • The brain lights up when working memory is active
     • When a task involves working memory, the prefrontal cortex lightsup.
       • If a task includes remembering numbers or words there will be activity on the left hemisphere.
         • If task involves spatial relations then the right hemisphere will also be active

2. Stress impairs working memory

   • More working memory equals better performance in school
