Understanding Forgetting: Interference Theory Explained

Interference Theory of Forgetting is a comprehensive explanation of memory loss that occurs when different pieces of information disrupt each other in long-term memory. The theory primarily focuses on two types of interference: proactive interference and retroactive interference, with similarity between memories playing a crucial role in the strength of interference effects.

Key points:

  • Interference is strongest when memories share similarities
  • McGeoch and McDonald's 1931 study provides empirical support
  • Real-world applications demonstrated through studies with rugby players
  • Drug studies support the theory through retrograde facilitation
  • Memory accessibility can be improved through proper cueing

Understanding Interference Theory

The page delves into the fundamental concepts of interference theory of forgetting and its supporting research.

Definition: Interference theory occurs when two pieces of information disrupt each other, primarily affecting long-term memory.

Types of Interference:

Vocabulary:

  • Proactive interference PIPI: When older memories interfere with newer ones
  • Retroactive interference RIRI: When newer memories interfere with older ones

Research Evidence:

Example: McGeoch and McDonald's 1931 study demonstrated that similar materials synonymssynonyms produced the worst recall, supporting that interference is strongest between similar memories.

Strengths of the Theory:

Highlight:

  • Drug studies support the theory through retrograde facilitation
  • Real-world evidence from studies with rugby players increases ecological validity
  • Interference effects can be overcome using proper memory cues

Limitations:

Highlight:

  • Laboratory studies may create artificially ideal conditions
  • Interference might be less common in everyday situations
  • Most forgetting might be better explained by alternative theories

Supporting Research:

Quote: "Coenen and Van Luijtelaar 19971997 found that recall of words learned under diazepam was poorer than the placebo control group, while recall of material learned before drug administration was better."

Memory Accessibility:

Example: Tulving and Psotka's research showed that category cues could restore recall levels to around 70%, suggesting interference causes temporary accessibility issues rather than permanent loss.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
