Memory: Forgetting Curve

In course

HUM-432: How people learn: Designing Learning Tools I

The students will understand the cognitive and social factors which affect learning - particularly in science and engineering. They will be able to use social research techniques as part of the design process to understand end users. ...

Description

This lecture covers the process of making memories, forgetting, repetition, and organization in long-term memory (LTM). It discusses Ebbinghaus' experiments on memory retention and the implications of forgetting in learning. By the end of the lecture, students should understand the Forgetting Curve and its application in memory experiments and learning.

Nihat Kotluk

Dr. Kotluk is currently a post-doc at the EPFL. He focuses mainly on emotions in the decision-making process, moral reasoning, and ethics in Engineering Education. He also works on equality and diversity issues. He has an academic background in both STEM and social sciences. Dr. Kotluk has acquired advanced skills in education, inclusive pedagogy, and science teachers' training. He has 14 years of teaching experience and has trained high school students in physics and teachers in pedagogy and research methods, among others. Dr. Kotluk has strong teaching and learning communication skills. He holds a Ph.D. in Educational Science, Curriculum, and Instruction. In his thesis, he studied the perceptions and practices of educators in culturally relevant pedagogy and developed recommendations to put more emphasis on inclusion in pre-service teacher education. With his research, he opened a new discussion in the academic community in Turkey and internationally. In his recent work, he analyzes the educational challenges facing refugee communities and other marginalized groups. In the study, he focused on whether and how teachers implemented the principles of culturally relevant and sustaining pedagogies and the challenges teachers faced while trying to implement these principles with Syrian students in Turkey. In his more recent work, he has studied moral emotions, moral reasoning in engineering ethics, and equality and diversity issues in engineering education. His teaching and research interests include emotions in engineering education, culturally responsive STEM education, equity and diversity in education, and multicultural education.

Memory

Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. Memory loss is usually described as forgetfulness or amnesia. Memory is often understood as an informational processing system with explicit and implicit functioning that is made up of a sensory processor, short-term (or working) memory, and long-term memory.

Long-term memory

Long-term memory (LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to short-term and working memory, which persist for only about 18 to 30 seconds. LTM is commonly labelled as "explicit memory" (declarative), as well as "episodic memory," "semantic memory," "autobiographical memory," and "implicit memory" (procedural memory). The idea of separate memories for short- and long-term storage originated in the 19th century.

Memory consolidation

Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term potentiation, occurs on a small scale in the synaptic connections and neural circuits within the first few hours after learning.

Forgetting curve

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is able to recall it. A typical graph of the forgetting curve purports to show that humans tend to halve their memory of newly learned knowledge in a matter of days or weeks unless they consciously review the learned material.

Recall (memory)

Recall in memory refers to the mental process of retrieval of information from the past. Along with encoding and storage, it is one of the three core processes of memory. There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humans and animals. Two main theories of the process of recall are the two-stage theory and the theory of encoding specificity.
