Theories of forgetting in psychology Rating:
There are several theories in psychology that attempt to explain why people forget information over time. These theories can help us understand the cognitive processes involved in forgetting, as well as identify strategies that may help people better retain information.
One theory of forgetting is the decay theory, which suggests that memories fade over time due to a lack of reinforcement or use. According to this theory, memories that are not regularly retrieved or practiced will eventually be lost. This can explain why people may have a harder time remembering information that they have not used in a while, such as a foreign language they learned in school but have not spoken in years.
Another theory is the interference theory, which suggests that new information can disrupt or interfere with the retrieval of old information. This can occur when there is competition between similar memories, or when the new information is closely related to the old information. For example, if someone is trying to remember a phone number but is presented with a similar phone number, it may be harder for them to recall the original number.
The cue-dependent forgetting theory suggests that people are more likely to forget information when they are not provided with the proper cues or context to help them retrieve it. For example, if someone is trying to remember a list of items but does not have the list in front of them, it may be harder for them to recall all of the items. Similarly, if someone is trying to remember a specific event, but does not have any visual or auditory cues to help them, they may have a harder time recalling the details of the event.
Finally, the repression theory suggests that people may forget certain memories due to psychological defense mechanisms, such as repression. According to this theory, people may unconsciously block out unpleasant or traumatic memories in order to protect themselves from emotional pain. While repression can be a helpful coping mechanism in the short term, it can also lead to forgetting important information or events.
Overall, there are several theories in psychology that help to explain why people forget information over time. Understanding these theories can help people identify strategies that may help them better retain information, such as regularly reinforcing and retrieving memories, organizing information in a way that helps with recall, and providing oneself with appropriate cues and context.
What is interference theory of forgetting in psychology?
Those who were given the category names recalled substantially more words than those who were not. The shorter the time interval, the more we will remember, and vice versa. State retrieval clues may be based on state-the physical or psychological state of the person when information is encoded and retrieved. One group did the learning section on the beach, and the other group did underwater. Tulving suggested that information about the physical surroundings Context external Cues Retrieval cues may be based on context-the setting or situation in which information is encoded and retrieved. Interference Theory If you had asked psychologists during the 1930s, 1940s, or 1950s what caused forgetting you would probably have received the answer " Interference". Read about How to Prepare for UPSC without Coaching The Retrieval Failure Theory of Forgetting Endel Tulving takes credit for developing the retrieval failure theory of forgetting in the year 1974.
Forgetting in Psychology: Definition, Causes & Types
This theory is based on the early studies conducted by Hermann Ebbinghaus on early memory. The idea that memories fade over time is hardly new. However, there is no doubt that interference plays a role in forgetting, but how much forgetting can be attributed to interference remains unclear Anderson, 2000. For example, you are more likely to remember your very first day of college than all of the intervening days between it and graduation. Motivated Theory of Forgetting Friedrich Nietzsche was one of the first psychologists to suggest that people intentionally forgot their memories. The Consolidation Theory of Forgetting Theorised by George Muller and Alfons Pilzecker in 1900, this theory is based on physiological evidence.
Data from Myers and Brewin 1994. For example, a person may be alert, tired, happy, sad, drunk or sober when the information was encoded. The two levels of motivated forgetting are repression and thought suppression a Repression - According to Sigmund Freud, we subconsciously push unwanted or painful memories into the unconscious for e. This occurs due i to the inadequate encoding of material ii improper storage iii incorrect retrieval cues iv the person is under emotional pressure at that time of recall. They named this phenomenon the Serial Position Effect. The more similar two or more events are to one another, the more likely interference will occur. In other words, the more similar the information, the easier it is to forget.
Who gave interference theory of forgetting? Examples of the Displacement Theory of Forgetting Suppose you have just learned a seven-digit phone number when you are given another number to memorize. Participants were asked to memorise a list of 36 unrelated words of two or three syllables. That first day was new and exciting, but all the following days probably seem quite similar to each other. This makes it very difficult to be sure that any forgetting which takes place is the result of decay rather than a consequence of the intervening events. The last few words that were presented in the list have not yet been displaced from short-term memory and so are available for recall. Initially, information is often lost very quickly after it is learned.
According to this method, the participants listen to many words following which they are asked to recall them. These findings suggest that the forgetting function is approximately logarithmic. Ebbinghaus initially learned a list of nonsense syllables having little or no meaning. This inability to form new memories is referred to as anterograde amnesia. Another tactic to fight interference is to switch up your routine and avoid studying similar material back to back. Forgetting is greatest when context and state are very different at encoding and retrieval.
What is interference and its types? Cambridge, UK: Cambridge University Press. Interference comes into play when the information stored has to be retrieved, as the new information interfere with our retrieval of older information and vice versa. State internal Dependent Cues The basic idea behind state-dependent retrieval is that memory will be best when a person's physical or psychological state is similar at encoding and retrieval. For example, name of fruits, name of animals etc. This theory of forgetting focuses on the physiological aspects of forgetting. The fact that HM's memory is disrupted for the two-year period leading up to the surgery indicates that the process of consolidation continues for a number of years. Memory: Phenomena, Experiment and Theory.
One of the problems with decay theory is that it is more or less impossible to test it. But first, what is the cue context-dependent Retrieval failure, or cue-dependent forgetting, is intended to explain the failure to recall information without cues. L: This means the theory has a real-world practical application making it useful outside of the psychology laboratory. Results: The recall of the control group was more accurate than that of the experimental group. The process of memory consolidation takes place when the memory is stabilised to prevent disruptions. When we take in new information, a certain amount of time is necessary for changes to the nervous system to take place — the consolidation process — so that it is properly recorded.
Memory retrieval requires us to revisit those traces that the brain formed when encoding the memory. Forgetting is the loss, either permanent or temporary of the ability to recall or recognize something that was learnt earlier. These cues can help recollect the details of the crime. Evaluation The research into the processes involved in consolidation reminds us that memory relies on biological processes, although the exact manner by which neurons are altered during the formation of new memories has not yet been fully explained. The Interference Theory of Forgetting John A.
Human Memory: Theory and Practice. Maybe memories start coming back as you walk around and see specific items. The theories can be classified as psychological, neurochemical, and physiological. Half of the underwater group remained there and the others had to recall on the beach. Why is it important to identify the forgetting function or functions? Through these studies, psychologists have discovered that the first and the last items on a list are the easiest ones to remember. Minami and Dallenbach 1946 carried out a study on cockroaches, which learned to avoid a dark box.
