Memory Levels of Memory A) Sensory: Records information from the senses for only a few seconds Encoding depends on attention

Memory Types of memory B) Short-term memory: Holds information for up to 15 or 20 seconds. Rehearsal helps information stay longer Short term memory can store about 7 ungrouped items.

Memory Test your short-term memory How many of the following ordered numbers can you remember ? You will have 5 seconds to memorize the following digit numbers. Mistakes in two consecutive rows represent the limit of shortterm memory.
