Why do we modify memories?
One reason we may modify memories is to keep them consistent with our schema. This may be the reason people are known to give inaccurate accounts of events.
What is the term for the inability to recall or recognize information that we think should reside in long-term memory?
Forgetting is the inability to recall or recognize information that we think should reside in long-term memory. Recall refers to reproducing or reconstructing a memory without a specific external cue; recognition refers to identifying something you learned previously based on external cues.
How does recalling a memory change it?
Recalling a memory changes it. The act of reconstructing a memory makes it relatively stronger than other memories and may modify its contents.
What is interference in memory?
Interference is a critical factor in forgetting. Retrieving a memory probably involves pattern completion. In this theory, the cue (such as a question) activates the associated schema to complete the pattern. Interference of one type or another can lead to failure of retrieving the correct information.
What is retroactive interference?
Retroactive interference (RI) occurs when newly learned information impedes the recall of something you previously learned. For example, if you are learning Spanish, you may not recall how to pronounce a word in French. The rules of Spanish pronunciation are interfering with this.
What is the meaning of consolidation of memories?
Consolidation of memories involves deep processing and associating information in a meaningful way with a network of learned information. Memories that are not consolidated are less stable.

When we learn a complex problem, the short-term memory is freed up and the action becomes automatic. Emotionally charged events are remembered better than those of neutral events.
What is the term for triggering behavior through unconscious suggestion?
4. Priming : Past memories are often triggered or primed by one’s environment. Priming refers to activating behavior through the power of unconscious suggestion. Research found that people who are made to think of self-discipline (by having to unscramble sentences about it) immediately made more future-oriented snack choices than those given sentences about self-indulgence. In this case, the goal stored in long-term memory is retrieved and placed in short-term memory. Similarly, the concept of a library causes people to speak more softly.

What is episodic memory?
The condition boils down to deficits in episodic memory, which involves storing knowledge of times, places, associated emotions, and basically everything else regarding “who, what where, and when.” Meanwhile, participants’ semantic memory was found to be strong, and in some cases superior to control subjects. Semantic memory is the ability to recall specific facts and concepts learned over a lifetime, such as how to use scissors or knowing that an event occurred — such as your friend scraping his knee in third grade.
Can people have memory problems?
It may be hard to grasp, but there are actually people who have these memory problems. Three of them were recently the subjects of a study on the condition, dubbed severely deficient autobiographical memory (SDAM), which researchers compare to living life in the third-person. “Many of us can relate to the idea that people have different abilities when remembering events. What is unique about these individuals is that they have no personal recollection,” said Dr. Brian Levine, senior scientist at the Baycrest Centre for Geriatric Care’s Rotman Research Institute, in a press release. “Even though they can learn and recall information normally and hold down professional careers, they cannot re-experience the past with a vivid sense of personal reliving. It’s as if their past was experienced in third-person.”
Why do people forget?
The Motivated Forgetting theory suggests people forget because they push unpleasant thoughts and feelings deep into their unconscious. People may actively work to forget memories, especially those of traumatic or disturbing events or experiences.

What is the term for the failure to recall a memory due to missing stimuli or cues that were present?
Retrieval failure is the failure to recall a memory due to missing stimuli or cues that were present at the time the memory was encoded. This theory is that a memory is temporarily forgotten simply because it cannot be retrieved, but with the proper cue that information can be brought to mind.
Why do we forget information?
The inability to retrieve a memory is only one cause of forgetting. We may forget because the information was never in long-term memory in the first place. The way information is encoded affects the ability to remember it. If it is not coded effectively, we will likely forget the information in the future. We may also forget specific information because we confuse it with other information which we have processed. Information may also be forgotten simply because we have not thought about in in a long time.
Why do we lose memories?
When information fades from working and short-term memory, it disappears because the space was needed for other incoming information . However, loss of long-term memories does not seem to depend on how much time has gone by since the information was learned. Most theorists believe that once information has been transferred to long-term memory it is stored there permanently. The theorists believe that the memory is always there, but the mental path to get to the memory has decayed. For example, people might easily remember their first day of high school, but completely forget the last movie they saw. This may be because of the strong links (emotion, visual, etc..) the person has to the memory. This is why people who see a horrific accident, have a hard time forgetting it.
What happens when information fades?
With the Decay theory, when information fades from long-term memory, what really fades is the link to that information, not the information itself. The information is there, but we just cannot find it. It is like a path in the woods that leads to a cabin; the more you use the path, the easily it is to find the cabin. However, if you do not use the path for several years, the path will eventually fade. The cabin will still exist, but will be harder to find because the path that leads there has faded. Fading can be prevented by encoding the information as meaningfully as possible, by frequently retrieving it, and by using effective memory strategies.
What does it mean to forget something?
1 . Forgetting typically involves a failure in memory retrieval. While the information is somewhere in your long-term memory, you are not able to actually retrieve and remember it.
Why is it so hard to remember what happened two months ago?

What is the purpose of recall?
Recall: People who have been asked to memorize something , such as a list of terms, might be asked to recall the list from memory. By seeing how many items are remembered, researchers are able to identify how much information has been forgotten. This method might involve the use of free recall (recalling items without hints) or prompted recall (utilizing hints to trigger memories).
What is the tendency to forget facts or events over time?
1. Transience. This is the tendency to forget facts or events over time. You are most likely to forget information soon after you learn it. However, memory has a use-it-or-lose-it quality: memories that are called up and used frequently are least likely to be forgotten.
How does memory affect perception?
In your memory, your perceptions are filtered by your personal biases — experiences, beliefs, prior knowledge, and even your mood at the moment. Your biases affect your perceptions and experiences when they're being encoded in your brain. And when you retrieve a memory, your mood and other biases at that moment can influence what information you actually recall.
Why do old people misassociate?
As with several other kinds of memory lapses, misattribution becomes more common with age. As you age, you absorb fewer details when acquiring information because you have somewhat more trouble concentrating and processing information rapidly. And as you grow older, your memories grow older as well. And old memories are especially prone to misattribution.
