1. INTRODUCTION OF PSYCHOLOGY Forgetting Theories 2. INTRODUCTION There are four major theories of forgetting that should be dicussed in some detail : Decay theory which states that time alone causes memory traces to fade. Interference theory which suggests that other memories interfere with remembering. Motivated forgetting theory which suggests that we forget information that is unpleasant or threatening. Retrieval failure theory which propose that information memory must be distorted when we attempt to recall it. * We will discuss about Decay Theory, Interference Theory & Motivated Failure Theory. 3. SIGNIFICANCE DECAY THEORY we do not know whether the failure to recall something reflects that it is no longer in our memory, or that it reflects retrieval failure. Perhaps it is still there but we cannot retrieve the memory for some reason. The theory that information in memory eventually disappears if it is not accessed (Wade & Tavris, 2011). 4. Interference theory Forgetting occurs because similar items of information interfere with one another in either storage or retrieval. The information may get into memory and stay there but it becomes confused with other information. PROACTIVE INTERFERENCE - When competing information that prevents recall has been learned before the forgotten item, as in the case of the forgotten phone number, the process is called proactive interference. 5. RETROACTIVE INTERFERENCE According to Comer & Gomer (2013), retroactive interference occurs when new information prevents the retrieval of previously learned information. French English French 6. MOTIVATED FORGETTING Motivated forgetting arises from strong motive or desire to forget, usually because the experience is to disturbing or upsetting to remember. For example, a) We do tend to recall more pleasant than unpleasant things. b) trauma victims dont have full memories of traumatic events. 7. Discussion Decay Theory Interference Theory Motivated Forgetting 8. CONCLUSION Decay theory, interference theory and motivated forgetting is three fact in forgetting theory that always happen to us. Therefore, either our memory may fade way, being interfered or even purposely forget, forgetting will always be happened if we did not trying to rehearsed. By focusing our learning strategies on the strengths of the brains memory systems, we may be able to learn more information.
