•Shortest in duration
•2-3 seconds
•visual, auditory, taste, smell
•also known as Working Memory
•duration about 18-20 seconds
•limited capacity
• 7 plus or minus 2 units of
information
•Duration-relatively permanent
•Capacity-unlimited
•Visual Memory- about 1 second
•Auditory Memory-longer than visual
•Attention-unusual, sudden, dramatic
•Recognition-experienced before, relevant
•Iconic-pictures, images

before. Fastest form of memory
retrieval
Decay: Lack of retrieval overtime,
memory may fade.
Interference: Old information is
replaced by new information.
Temporary of permanent inability to remember.
Causes:
Physiological-injury
Substance Abuse-Alcohol, THC
Psychogenic-trauma, emotional shock
Types of Amnesia
Retro-grade- Can’t form new memories.
Anterograde-Can’t access old memories
