1 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting Module 12 Remembering & Forgetting

2 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting ORGNIZATION OF MEMORIES Network theory of memory organization –theory says that we store related ideas in separate categories, or files, called nodes Associations –linking of nodes or categories of ideas together by making associations or mental roads between new information and old information that was previously stored Network –thousands of interconnected nodes, which form an enormous cognitive network for arranging and storing files

3 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting p262 NORMAN TRAIN OF THOUGHT

4 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting ORGNIZATION OF MEMORIES (CONT.) Organization of network hierarchy –refers to the arrangement of nodes or memory files in a certain order or hierarchy –bottom of the hierarchy are nodes with very concrete information, which are connected to nodes with somewhat more specific information, which in turn are connected to nodes with general or abstract information

5 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting FORGETTING CURVES Unfamiliar and uninteresting –forgetting curve measures the amount of previously learned information that subjects can recall or recognize Familiar and interesting –remembering is partly related to how familiar or interesting the information is

6 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting REASONS FOR FORGETTING Overview: forgetting –refers to the inability to retrieve, recall, or recognize information that was stored or is still stored in long-term memory Repression –according to Freud, repression is a mental process that automatically hides emotionally threatening or anxiety-producing information in the unconscious, from which repressed memories cannot be recalled voluntarily, but something may cause them to enter consciousness at a later time

7 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting REASONS FOR FORGETTING (CONT.) Overview: forgetting –poor retrieval cues/poor encoding –retrieval cues are mental reminders that we create by forming vivid mental images or creating associations between new information and information we already know Interference –common reason for forgetting –recall of some particular memory is blocked or prevented by other related memories

8 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting REASONS FOR FORGETTING (CONT.) Overview: forgetting –Amnesia may be temporary or permanent, is loss of memory that may occur after a blow or damage to the brain or after disease –Distortion we misremember something due to memory distortions caused by bias or suggestibility

9 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting REASONS FOR FORGETTING (CONT.) Interference –Proactive interference occurs when old information (learned earlier) blocks or disrupts the remembering of related new information (learned later) –Retroactive interference occurs when new information (learned later) blocks or disrupts the retrieval of related old information (learned earlier)

10 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting REASONS FOR FORGETTING (CONT.) Retrieval cues –mental reminders that you create by forming vivid mental images of information, or associating new information with information that you already know Tip-of-the-tongue phenomenon –refers to having a strong feeling that a particular word can be recalled, but despite making a great effort, we are temporarily unable to recall this particular information

11 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting BIOLOGICAL BASES OF MEMORY Location of memories in the brain –cortex Short term memories –ability to hold words, facts, and events in short- term memory depends on activity in the cortex Long term memory –ability to remember or recall songs, words, facts, and events for days, months, or years depends on areas widely spread throughout the cortex

12 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting p268 AREAS BRAIN INVOLVED MEMORY

13 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting BIOLOGICAL BASES OF MEMORY (CONT.) Location of memories in the brain –Amygdala: emotional memories the amygdala, located in the tip of the temporal lobe receives input from all the senses and is associated with emotional memory –Hippocampus: transferring memories transfers words, facts, and personal events from short-term memory into permanent long- term memory

14 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting BIOLOGICAL BASES OF MEMORY (CONT.) Making a short-term memory –Neural assemblies groups of interconnected neurons whose activation allows information or stimuli to be recognized and held briefly and temporarily in short-term memory

15 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting p269 NEURAL ASSEMBLY MEMORY

16 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting BIOLOGICAL BASES OF MEMORY (CONT.) Making a long-term memory –Long-term potentiation (LTP) refers to change in the structure and function of neurons after they have been repeatedly stimulated neuroscientists believe that the LTP process, which changes the structure and function of neurons, is the most likely basis for learning and memory in animals and humans

17 Introduction to Psychology, 7th Edition, Rod Plotnik Module 12: Remembering & Forgetting MNEMONICS: MEMORIZATION METHODS Improving your memory –Mnemonic methods ways to improve encoding and create better retrieval cues by forming vivid associations or images, which improve recall. –Method of loci encoding technique that creates visual associations between already memorized places and new items to be memorized –Peg method encoding technique that creates associations between number-word rhymes and items to be memorized
