After studying these articles, the research question for this experiment is; is it easier to recall positive, negative words or neutral words? To answer this question, an experiment will be conducted. The experiment will have positive, negative and neutral words shown to the participants, and they will have to recall at the end as many words as they can. The prediction for this is that more negative words will be remembered overall, as negative emotions can greatly affect people no matter what they are feeling. Doerksen & Shimamura (2001) investigated whether or not emotional words affect memory compared to neutral words. They did this, as they wanted to know the extent of enhancing emotions on recalling items previously presented to participants affect the …show more content…
Doerksen & Shimamura (2001) conducted three experiments to test this. For all experiments, they used 24 undergraduates from University of California, Berkeley. In the first experiment, 164 words were produced, 64 neutral and 64 emotional. Participants silently watched the randomised words on the monitor, which were shown for two seconds each for five minutes. The words were also either in yellow or blue. After this, participants then wrote down as many of the words they could recall. Following this, the words were then shown in black, and the participants had to determine which of the words were in yellow, blue or was a new word. Experiment two was conducted similarly, except the words were shown in black with a white background, which had a yellow or blue border. A third experiment was then conducted, similar to the second experiment except the emotional words were replaced with categorical words. From conducting these experiments, Doerksen & Shimamura (2001) got similar results for all three

Over the years, memory have been researched and debated, however there are two theories that have explained extensively and are highly recognised by psychologist in the cognitive field of psychology and scientist alike, on how we process experiences and turn them into memories. These theories include the Atkinson and Shiffrin (1968) Multi-store Model of Memory and Baddeley and Hitch (1974) Phonological Loop Model of Memory. This essay aims to compare, contrast and evaluate these models of memory, with supporting evidence and empirical research.
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.

When someone creates a memory, especially one which is a flashbulb, they generally feel confident in what they remember. The events which are especially full of emotion are often recreated with vividness and confidence (Romeu, 2006). These memories however are no more accurate than an everyday memory (Weaver, 1993). Studies show people will forget flashbulb memories at the same rate as other memories. In a study from 2012, researchers looked at the effects of emotional intensity in regards to memory. The subjects were shown a collection of 60 photographs which contained 20 colored dots in the center of the photograph. After viewing the photographs the participants watched a neutral video for an hour and then were ...
The article How to Tell If a Particular Memory Is True or False by Daniel M. Bernstein and Elizabeth F. Loftus, addresses the various techniques used by cognitive scientists and other researchers in hopes of distinguishing true from false memories. For this article Loftus and Bernstein, memory researchers, chose to discuss the different methods currently used, rather than trying to find new ways to tell if a particular memory is true or false. Their findings in these three different approaches are very interesting, and leads us to think critically of the veracity of true and false memories.
The film emphasizes on the power of our long-term memory and our episodic memories. Would we be happier if we forgot about traumatic past experiences? Or are our long-term memories so tangled up with emotions and sensations that our brain is unable to truly let go of long-term memories? The film also looks at the difference between explicit and implicit memories.

Research has shown that even though information may be committed to memory, what is retrieved can be altered during the encoding process. It has been said that, “the recollection of memory can be manipulated and or large aspects of the event can be confabulated.” (Cain,1997). Moreover, the recollection of past experiences can negatively affect future decisions, opinions, and more significant outcomes such as an eyewitness. This type of impact is due to something called, “false memories.” False memories can be defined as “an recollection of an event that never actually occurred.” False memories are said to be normal occurrences and have little impact on lives. However, Loftus and Palmer argue something different. In 1974, Loftus and Palmer conducted an experiment to test out the theory behind “false memories.” Their aim was to show that language used in eyewitness testimony can alter memory. People in this experiment were asked to estimate the speed of motor vehicles using different ways of questioning. Loftus and Palmer asked questions in regards to vehicle speed because typically that is something that most people are bad at estimating. Therefore these people would be more vulnerable and open to suggestions. The procedure of this experiment involved participants watching a video of cars. Participants were asked what they had seen in regards to how that car came in contact with the other car. Loftus and Palmer used words like “crashed, collided, hit, and smashed.” Their findings concluded that the estimated speed was affected by the verb used to describe the cars’ contact with one another. It seem as if participants saw that the verbs as clues of the speed the cars were going. Loftus and Palmer also came to the conclusion that there could only be two reasons for their findings. Those reasons were Response- bias factors or the fact that the memory representation is alter.
Craik and Tulving did a series of experiments on the depth of processing model. They had participants use a series of processing methods to encode words at different levels; shallow, moderate, and deep. The subjects were shown a series of words and ask questions about the words that would provide a "yes" or "no" response. At the shallow level they were asked questions about whether or not the word was written in capital letters. At the moderate level of processing, the subject was asked questions as to whether or not two words rhymed. Finally, the subjects were asked about words in sentences and whether or not they fit. This was the deep level of processing. After participants had completed the task they were then given a surprise recognition test with the words that they were just asked questions on (target words) and then words that they have never seen before (distraction words). The results of the experiment showed that people remembered the words better that were at deeper level of processing (Craik and Tulving 1975).
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 general public and many researches were done in order to find more about the false memory. The constructive approach to memory, which states that memory is constructed by person based on what really happened in addition to person’s other knowledge, experiences, and expectations, supports the idea of false memory. Just like what constructive approach to memory states, the false memory can be created by person’s knowledge, common biases, and suggestions. The present study was done in order to demonstrate one methodology that biases people to create and recall false memories. The present study is based on Deese’s experiment in 1959 and also on Roediger and McDermott’s experiment in 1995. The participants will be presented with sequence of words visually, and then they would have to classify a set of words as either in the sequence or not in the sequence. Our hypothesis is that people will create false memories and recall distractor words that are related to the sequence of words presented significantly m...
The findings of this research would reinforce findings of previous research specifically in relation to the robustness of false memories. The experiment undertaken by students will also be helpful to the study of false memories specifically to test the reproducibility of this type of experiment.

affect our memory. It is important to be aware of these factors and to question the accuracy of our own memories. commit due to inaccurate eyewitness testimony. Cognitive psychologists have conducted extensive research on the reliability of eyewitness testimony and have found that it can be influenced by a variety of factors, including stress, leading questions, and post-event information. In fact, studies have shown that eyewitnesses are often inaccurate in their descriptions and identifications, which can have serious consequences for the accused.
