The Three Separate Memory Systems:
|
-sensory memory
-short-term memory -long-term memory |
7 Sins of Memory:
|
-blocking
-absentmindedness -transience -misattribution -bias -suggestibility -persistence |
Three Types of Forgetting:
|
-Blocking
-Absentmindedness -Transience |
Absentmindedness
|
-one of the 7 sins of memory
-type of forgetting -reduced memory due to failing to pay attention ex: forgetting where you put your keys or that you planned a lunch date |
Transience
|
-one of the sins of memory
-type of forgetting -reduced memory over time ex: forgettting the plot of a movie you saw last year -information has decayed |
Blocking
|
-one of the seven sins of memory
-type of forgetting -inability to remember important information, such as failing to recall the name of seomeone you met on the steet. |
Misattribution
|
-one of the 7 sins of memory
-type of distortion -assigning a memory to a wrong source, such as falsely thinking that "Richard Schiffrin" is famous |
Bias
|
-one of the 7 sins of memory
-type of distortion -influence on current knowledge on our memory for past events, such as remembering our past attitudes as similiar to our current attitudes even though they have changed |
Suggestibility
|
-one of the 7 sins of memory
-type of distortion -altering a memory because of misleading information, such as developing false memories for events that did not happen example: you witness a robbery, you read things in paper and hear things from other people and you start believing that that is what you witnessed |
Persistence
|
-one of the 7 sins of memory
-type of distortion -the resurgence of unwanted or disturbing memories that we would like to forget such as a time when we were embarassed ex: post-traumatic stress disorder |
Sensory Memory
|
-one of the memory systems
-encodes a raw copy of whatever it is that you experience -doesn't translate it into any other form (no encoding or conversion) -information is lost from sensory memory over time by decaying -information is available in sensory memory from 250 ms -capacity is unlimited (we can remember as much as we can pay attention to at one time, for no longer than 250 ms) -The Modal Model -2 types of sensory memory: iconic memory and echoic memory |
Modal Model of Sensory Memory
|
-model of sensory memory
-Sperling (1960) -whole report procedure -partial report procedure |
Whole Report Procedure
|
-procedure of the modal model of sensory memory
-people could generaly report 4-5 (33-42%) of the letters originally shown -presented 12 letters on the screen for 50 ms and asked participants to repeat what they saw: people were very accurate when making guesses on what letters appeared and in what spot without even consciously recalling it |
Partial Report Procedure
|
-procedure of the modal memory of sensory memory
-presented 12 letters for 50 ms -asked to report all letters in row indicated by tone: -high pitch=top row -medium pitch= middle row -low pitch= bottom row -he's assuming there's a display that's in memory for 250 ms -3.3 out 4 (82%) letters were accurately reported |
Types of Sensory Memory
|
-Iconic Memory
-Echoic Memory |
