What is encoding?
Converting environmental & mental stimuli into memorable brain codes
Holding on” to encoded information
a. Pulling information from storage
a. (1) Sensory memory- hold information in its original form only for an instant
i. Capacity: Sperling’s experiment suggested a capacity of 9-12 items
ii. Duration: is very brief with most gone in less than 1 second
b. (2) Short Term Memory- Memory system in which information is held for brief periods of time while being used
i. Capacity: The digit span test suggests the average capacity is between 5-9 items
ii. Duration: only lasts for roughly 30 seconds
c. (3) Long term memory: permanent type of memory that holds huge amounts of information for a long period of time
i. Storage and duration are thought to be unlimited
a. grouping units into higher order units that can be remembered
a. Assumes information that is more “deeply processed,” or processed according to its meaning rather than just the sound or physical characteristics of the word or words, will be remembered
more efficiently and for a longer period of time
Declarative memory (explicit): conscious recollection of information such as specific facts or events
i. Semantic memory: involves general knowledge
ii. Episodic memory: retention of autobiographical information
a. (Implicit) Behavior is affected by prior experience without that experience being consciously recollected (remembered)
i. Procedural Memory: memory for skills that often don’t require direct attention and continual conscious awareness to learn and improve
a. a type of incidental learning where exposure to events that influence future behavioral, emotional, and/or cognitive responses, which are generally unintentional
a. Recall- memory task without cues
b. Recognition- memory task with cues to help recognize learned items
a. People recall information better when they are in the same psychological state or mood as learning
a. If given a list, only the beginning and end of the list will be memorized better than the middle
i. Primary Effect: Good at memorizing things in the beginning of the list
ii. Recency Effect: Good at memorizing things in the beginning of the list
a. (Possibilities for Forgetting) Information never makes it into storage (long term memory)
a. Forgetting can result from failure to retrieve information from long term memory
a. Information learned EARLIER (list A) interferes with information learned LATER (list B)
a. Information learned LATER (list B) interferes with information learned EARLIER (list A)
a. Amnesia: significant and abrupt loss of memory
i. Organic versus Nonorganic (Psychogenic) Amnesia
ii. Retrograde versus Anterograde Amnesia
