The subject is then asked recall theĪlthough it is widely known that benzodiazepines impair episodic memory, few studies have investigated their effects upon specific processes involved in free recall. Each item is introduced at a regular interval. The items to be remembered are presented on a manner of reading the list to the subject. In this method the subject is given a list of various items (words of the same length) that should be remembered. One of the ways to demonstrate serial position curve is by means of using a free recall task using a verbal learning test such as Rey Auditory Verbal Learning Test (RAVLT). Theoretical Background The theoretical construct of serial position curve is that the primacy effect represents recall from a more remote memory or long term memory which is better consolidated than the recency effect which represents recall from a more recent memory or working memory (Glanzer & Cunitz, 1966). Primacy effect refers to the better recall of items from the beginning of list (first three or four items) whereas recency effect refers to the better recall of items from the end of the list (last three or four items) than middle items of the list. The serial position effect consists of two phenomena viz. This occurs due to a phenomenon known as Serial Position Effect. First described by Nipher (1878), the serial position curve can be defined as a " U-shaped relationship between a word's position in a list and its probability of recall ". Synonyms U shaped learning curve Definition Serial position curve is a 'U' shaped learning curve that is normally obtained while recalling a list of words due to the greater accuracy of recall of words from the beginning and end of the list than words from the middle of the list.
