The theory of encoding specificity finds similarities between the process of recognition and that of recall. The encoding specificity principle states that memory utilizes information from the memory trace, or the situation in which it was learned, and from the environment in which it is retrieved.
In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
This experiment showed a recognition of the mobile, as well as recall (after one week), and cued recall (after 2 weeks). Recognition and recall are two essential aspects of memory; these are particularly useful in children since verbal reporting of memory may not be available yet or as reliable when testing very young participants.
Modern studies show an increased effect of levels-of-processing in Alzheimer patients. Specifically, there is a significantly higher recall value for semantically encoded stimuli over physically encoded stimuli. In one such experiment, subjects maintained a higher recall value in words chosen by meaning over words selected by numerical order. [26]
Using this paradigm, researchers can look into the mechanisms of neuro-biological functions as well as social aspects of disorders and illnesses that plague humans. Recognition memory has been linked to advancements in the understanding of schizophrenia, epilepsy and even explaining simple autobiographical memory loss as we grow older.
Recall refers to the re-accessing of previously learned information held in long-term memory stores. During this process, the brain relays a specific pattern of neural activity that echoes the original perception of that event. [12] Regular recalling of stored information helps to improve memory retention.
A practical application of recognition memory is in relation to developing multiple choice tests in an academic setting. A good test does not tap recognition memory, it wants to discern how well a person encoded and can recall a concept. If people rely on recognition for use on a memory test (such as multiple choice) they may recognize one of ...
Researchers distinguish between recognition and recall memory. Recognition memory tasks require individuals to indicate whether they have encountered a stimulus (such as a picture or a word) before. Recall memory tasks require participants to retrieve previously learned information.
