Analyzing the Effect of Surprise Recall and Expected Recall on Memory
Whether or not we acknowledge it, memory is one of the most important processes that our brain preforms every day. Everything we do sensory or procedural is recorded in some way into our memories, some memories only last a brief amount of time while others may last a life time depending on the amount of rehearsal and encoding. Though this is by far not a perfect system, we create schemas in our brains (or short-cuts) to aid in memory; yet sometimes due to these schemas we actually not remember something properly creating a false memory (Olszewska & Ulatowska, 2013). This due to an error in the person’s episodic memory, this is the type of memory that is person specific for remembering events; word pairs or particular words seen in a list (Cabeza et al., 1997). Finding put such a phenomenon has led to many to study how memory works, and ways too mesure what memory actually is. We can test this episodic memory using recall tests in which participants try to write the remembered word. Another test would be a recognition test in which studied items, such as a word list, are mixed with new words. The participants have to decide “yes or no” that the item was previously seen before (yes) or novel (no) (Cabeza et al., 1997).
There have been studies in the past conducted to find where exactly in the brain memory may reside, using positron emission tomography (PET) scans to see where the most blood flows into the
How is memory encoded and what methods can lead to greater recall? There have been many different models suggested for human memory and many different attempts at defining a specific method of encoding that will lead to greater recall. In this experiment subjects are asked to do a semantic task on a word related to them and an orthographic task in which they analyze the letter in the word. The results of the experiment indicate that the words which where encoded semantically and are related to the self have greater recall.
The study of creation of false memories has been a topic of interest since the 1930s when Bartlett (1932) conducted the first experiment on the topic. Though the results of this experiment were never replicated, they contributed greatly to research by distinguishing between reproductive and reconstructive memory (Bartlett 1932 as cited in Roediger & McDermott, 1995). Reproductive memory refers to accurate production of material from memory and is assumed to be associated with remembering simplified materials (e.g., lists). Reconstructive memory emphasizes the active process of filling in missing elements while remembering and is associated with materials rich in meaning (e.g., stories).
Memory is not located in just one spot of the brain, but it is a brain wide process, in which
Memory is the process of encoding, storing and retrieving information in the brain. It plays an import role in our daily life. Without memory, we cannot reserve past experience, learn new things and plan for the future. Human memory is usually analogous to computer memory. While unlike computer memory, human memory is a cognitive system. It does not encode and store everything correctly as we want. As suggested by Zimbardo, Johnson and Weber (2006), human memory takes information and selectively converts it into meaningful patterns. When remembering, we reconstruct the incident as we think it was (p. 263). Sometimes our memory performance is incredibly accurate and reliable. But errors and mistakes are more commonly happen, because we do
Due to this, it has been deemed difficult to determine which deficit is the consequence of which part of a lesion. To overcome this problem, other methods are being used to aid in the visualisation of memory processes in the healthy parts of the brain. These come in the form of functional neuroimaging studies using Positron Emission Tomography (PET) and Functional Magnetic Resonance Imaging (fMRI). These studies have allowed researchers to target specific memory processes using targeted psychological experiments. However, with all psychological experiments, there are limitations to using neuroimaging equipment. PET and fMRI attain their signals from local changes in blood flow or metabolism correlated with neural activity rather than from brain waves (or signals). The local vascular changes affect the distribution of an injected radionuclide (e.g. O15) in PET or magnetic properties that are blood-oxygen level dependent (BOLD) in fMRI. The indirect measure of neural activity limits the temporal and spatial fidelity of activations.
Memory is one of the most critical parts of cognition. It is important because it is involved in almost every aspect of cognition including problem solving, decision making, attention, and perception. Because of this importance, people rely on one’s memory to make important decisions. The value of one’s memory in this society is so high that it is used as evidence to either save one’s life or kill one’s life during murder trials. But as many of the cognitive psychologists know, human’s memory can cause many errors. One of these errors is false memory which is either remembering events that never happened or remembering events differently from the actual event. This finding of false memory raised big interests among psychologists and
Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process
False memory, second to forgetting, is one of the two fundamental types of deformation in episodic memory (Holliday, Brainerd & Reyna, 2010). Simply stated, false memory is the propensity to account normal occurrences as being a fraction of a key experience that in actuality was not an element of that experience (Holliday, Brainerd & Reyna). False memories are something nearly everyone experience. Furthermore, false memory is defined as placed together, constructed representations of mental schemas that are incorrect (Solso, MacLin & MacLin, 2008). Individuals do not intentionally fabricate their memory. However, perceptual and social factors are a few things that a responsible for manipulating memory (Solso, MacLin & MacLin, 2008).
Neurobiological studies show that both suppression and recall and the creation of false memories are possible. (Kandel, 1994) In this paper both sides of the debate will be analyzed and evaluated.
The experiment is as follows; one hundred students, randomly selected, participated in a context dependent memory experiment. twenty five were in each of the four following learn-recall situations; hot room-hot room, hot room-cold room, cold room-cold room, cold room-hot room. They were asked to spend thirty minutes learning a list of thirty words. The next day they were asked to recall those words in a fifteen minute time period. There are no results.
When speaking about memory, one needs to look at the parts of the brain that are
There are two prominent distortions of the episodic memory system: forgetting and the false memory effect. False memory is the propensity to report an event as part of an episodic experience that was not actually present (Holliday, Brainerd, & Reyna, 2011). Several theories give an explanation for this effect, but the most prominent one is the fuzzy trace theory,
Roediger and McDermott’ (1995), experiment based on Deese’s (1959) experiment renewed the interest in false memories and invented the Deese-McDermott-Roediger Paradigm which many studies surround. Their study focused on eliciting false memories through receiving lists of words and being asked to recall those that were present from a separate list that included a critical word that if recalled, showed presence of false memory effects. Notably many participants were sure that the
Memory facilitates necessary functions in daily life activities, but it is not a perfect mechanism in operation. Goldstein (2011) states that memory is, “…the process involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present” (p.116). There are many adaptive functions within the complexities of the human memory system and the interlinked constructs between each function leave room for doubt in the accuracy of recollection. Study of the human mind has opened avenues of discovery on the inner workings of our brains and the resulting knowledge suggests that humans are prone to creating false memories and even remembering things that never actually happened. A great deal of information has been written explaining the nature of memory errors and within the following pages a real-life case offers a glimpse into how recall distortions and memory errors can wield unpleasant consequences. Memory errors can be avoided with a significant effort, but the truth remains that no one is perfect and memories are subject to individual bias.
Central idea: Memory is a process of the brain which is prone to certain failures, although specific steps can be taken to guard against these failures.
