In our daily lives, we constantly try to store and retrieve information from our memory. Sometimes the retrieval process is quite simple, while other times it seems to be almost impossible. An experiment was done to investigate the effect of list position on free recall. The serial position effect refers to the U-shaped pattern presentation on a free recall task. The accuracy of item recall depends on the order that the stimulus is presented. The serial position curve is an example of how the recency and primacy effect appears to have influence on recall. Primacy effect results from initial observations and it is believed that the first few items of the list is remembered the second best. The recency effect results from the final observations and it is believed that these are the items that are recalled the best. The regency and primacy effect lends support to the interference theory. This theory states that forgetting occurs as a result of interfering information with the recall information. There are two aspects to this theory- retroactive interference and proactive interference. Retroactive interference occurs when a participant has difficulty recalling old information due to the interference of newly learned information. The primacy effect is subjected to the retroactive interference. In contrast, proactive interference occurs when a participant has difficulty learning new information due to the already learned information. The recency effect is subjected proactive interference.

...to recover cups from drawers while memorizing the letters inside the cups. The first two experiments used forward serial recall while the third experiment used free recall. The study conducted conflicted with the results of serial position curve. In this study, the recency effect was eliminated and the primacy effect was attained. Although previous studies were able to show that the recency effect can eliminated if there is a sufficient amount of interference after learning, the same reasoning could not be applied in this study, as the perceptual task was not preformed longer here. These findings provide evidence that the recency effect was eliminated due to motor interference. This study suggests that demanding motor tasks effects memory due to proactive interference. Thus, Serial position experiment can aid I adjusting our current knowledge about memory.
This investigation looks at retrieval failure in the long-term memory, particularly context-dependant forgetting. The theory behind retrieval failure is that available information stored in the long-term memory cannot be accessed because the retrieval cues are defective. Cue-dependant forgetting theory focuses on the assumption that the context in which we learn something is significant when we come to recall the information. Recall is better if it takes place in the same context as the learning. Research conducted on retrieval failure includes Tulving and Pearlstone (1966) who studied intrinsic cues by asking subjects to learn a list of words from different categories.

The experiment consists of two people that take part in a study of memory learning, one of them referred to as the "Teacher" and the other as the "Learner." The experimenter explains that the study's main goal is to observe the effect of punishment on learning. The learner will be seated in something similar to the electric chair, his arms will be strapped and an electrode will be attached to his wrist. The learner will be told that he will be tested on his ability to remember the second word of a pair when he hears the first one again. If he makes a mistake, he will then receive electric shocks of increasing intensity.
The second stage of memory processing is storage. Aronson et al. (2013) defines storage as the process by which people store the information they just acquired. Unfortunately, memories are affected by incoming information through alteration or reconstruction. This phenomenon is referred to as recon...

Altogether this study has helped us learn more about the brain and memory. Learning is measured thorough when a student can reiterate the right answer to a question. In this study, students in one conditions learned forging language vocabulary words in standard example of recurrent study exam trials. In three other conditions, once a student had correctly formed the language item, it was constantly studied but dropped from further testing. Repeatedly tested but dropped from the further study or just dropped from both the study and also the test. The results reveal the critical part of retrieval practice in combining education and shows that even college students seem naive of the fact.
The procedure is simple. On the computer screen, twelve words are revealed one word at a time in the form of a list. After the last word, a matrix of twelve words is shown. The matrix is a table of twelve words, some of which were on the list, some of which were not. Participants in the task chose which words they believe were on the list, using free recall to select words in any order. A new list begins when participants believe they have all of the correct words from the matrix. The cycle begins again. A list of twelve words are presented, a matrix appears after the twelfth word, and participants select words according to their memory of what was on the list. There are six lists in total, with no practice trials, however there are breaks in between to express the differences in each list.
...Baddeley (1966) study of encoding in the short term memory and long term memory supports the MSM model on the mode of processing such that words are processed on recall and both models share the same opinion that processing does influence recall. Finally, the MSM model of memory states that all information is stored in the long term memory, however, this interpretation contrasts with that of Baddeley (1974) who argue that we store different types of memories and it is unlikely that they occur only in the LTM store. Additionally, other theories have recognised different types of memories that we experience, therefore it is debatable that all these different memories occur only in the long-term memory as presumed by the multi-store model which states the long term memory store as with unlimited capacity, in addition it also fails to explain how we recall information.
Human memory is flexible and prone to suggestion. “Human memory, while remarkable in many ways, does not operate like a video camera” (Walker, 2013). In fact, human memory is quite the opposite of a video camera; it can be greatly influenced and even often distorted by interactions with its surroundings (Walker, 2013). Memory is separated into three different phases. The first phase is acquisition, which is when information is first entered into memory or the perception of an event (Samaha, 2011). The next phase is retention. Retention is the process of storing information during the period of time between the event and the recollection of a piece of information from that event (Samaha, 2011). The last stage is retrieval. Retrieval is recalling stored information about an event with the purpose of making an identification of a person in that event (Samaha, 2011).

According to Sternberg (1999), memory is the extraction of past experiences for information to be used in the present. The retrieval of memory is essential in every aspect of daily life, whether it is for academics, work or social purposes. However, many often take memory for granted and assume that it can be relied on because of how realistic it appears in the mind. This form of memory is also known as flashbulb memory. (Brown and Kulik, 1977). The question of whether our memory is reliably accurate has been shown to have implications in providing precise details of past events. (The British Psychological Association, 2011). In this essay, I would put forth arguments that human memory, in fact, is not completely reliable in providing accurate depictions of our past experiences. Evidence can be seen in the following two studies that support these arguments by examining episodic memory in humans. The first study is by Loftus and Pickrell (1995) who found that memory can be modified by suggestions. The second study is by Naveh-Benjamin and Craik (1995) who found that there is a predisposition for memory to decline with increasing age.
In the field of cognitive neuroscience a memory study usually involves a combination of behavioral tasks and a machine that permits t...
The serial position effect is defined by the likelihood to remember, or recall, the first and last items in a series, or a list, rather than the middle items. This creates a U-shaped curve when graphing this event. The primary effect is defined by the tendency to remember the beginning of the series. The recency effect is defined by the tendency to remember the last few items of the series. An explanation for this phenomenon is as such, the first set of items in a series is put into long-term memory as a result of rehearsal. The last set of items is put into short term memory. The items in the middle of the series were poorly recalled because they were not efficiently put in the short term memory because a lot more items came afterward. This
In everyday life, we use our memory widely to carry out daily tasks. Memory is a topic that has become a primary focus in investigation for many years. According to Goldstein (2011), memory is a process involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present. Memory stores and retrieves information. The Atkinson-Shiffrin model is a theory of human memory that was proposed by Richard Atkinson and Richard Shiffin in 1968. The theory labelled as “stage theory” is widely accepted and the focus of the model is on how memory is stored. There are three main structure features that contain different physiological properties namely sensory memory, short term memory and long term memory (refer to Figure 1 in Appendix 1).
