Sensory memory - attention - short term memory - rehearsal - long term memory

Sensory information

Iconic memory

Quick visual sensory memory

Echoic memory

Long-term memory

Long-term potentiation (LTP)

Process where repeated activities between neurons strengthens their connection, making it easier to recall

Phonological loop

Handles verbal and auditory information(remembering a phone number)

Visuospatial Sketchpad
