Activity 3: Long term memory strategies

Long-term memory is the final stage information flow model, this provides the lasting retention of information and skills. There is different types of long term memory . Procedural memory is is responsible for knowing how to do things.  Semantic memory is responsible for storing information about the world and Episodic memory is responsible for storing information about events. Duration varies from few minutes to lifetime.

Bahrick et al. (1975) investigated very long term memory (VLTM). Nearly 400 participants aged 17 – 74 were tested.  There were various tests including:  A free recall test, where participants tried to remember names of people in a graduate class. A photo recognition test, consisting of 50 pictures.  A name recognition test for ex-school friends. Results of the study showed that participants who were tested within 15 years of graduation were about 90% accurate in identifying names and faces. After 48 years they were accurate 80% for verbal and 70% visual.  Free recall was worse. After 15 years it was 60% and after 48 years it was 30% accurate.

Here Danah Henriksen explains his experiemtns about the long term memory. His designed the experiment to test long-term memory, based on both immediate and delayed recall of a list of twenty words.
