When thinking about the ‘key features’ of long-term memory in order to answer this essay question, the first elements that come to mind are the different kinds of long-term memory that humans have in order to retain information, and which is the most effective/ important when comparing them all. The key features of long-term memory (LTM) that will be explored in this essay, as shown by Keane and Eysenck (2015), come under ‘declarative’ memory. Within declarative memory, both episodic and semantic memory is going to be evaluated and discussed. During the discussion; duration, capacity and accuracy will be examined and comparisons will be drawn between the features in order to choose to most effective feature of long-term memory.

For example, Bahrick et al (1975) conducted a study looking at old photographs of ex-students from school yearbooks. Keane and Eysenck (2015) stated that “Ex-students showed remarkably little forgetting of information about their former classmates’ names at retention intervals up to 25 years. Performance was 90% for recognising classmates’ names” (p. 270). From this study we can infer that episodic memory shows to have excellent retention and duration ability, as the majority of information regarding ex-students’ names was retained for up to 25 years. In addition to this, this study shows the importance of episodic memory, as it allows access to old information encoded in the past, but it also reveals that memories from this feature can be easily triggered by certain stimuli such as images, and knowing this shows that triggering recall of episodic memories may be much easier than for semantic memories. This trigger for recall that was demonstrated in this study can be applied the real world in revision situations, as students could use images to help recall information for an exam. So, this shows that episodic memory is very valuable and without it we would lack the ability to remember events from the past and other information that we encoded during that event. However, it is important to argue about the possibility of semantic memory being the most important feature of long-term
