Psychology research papers on memory
Well-developed perceptual systems provide a continuous flow of abundant and up-to-date This phenomenon is known as the weapon effect - when a witness is involved in a situation in which a weapon is present, they have been found to remember details less accurately than a similar situation without a weapon.
We are able to recall minute details of our personal circumstances whilst engaging in otherwise mundane activities when we learnt of such events.
Participants were shown a list of 60 words, which they then answered a question about which required either shallow processing or more elaborative rehearsal. Loftus found when the question suggested that the crash had been severe, participants disregarded their video observation and vouched that the car had been travelling faster than if the crash had been more of a gentle bump Loftus and Palmer, But why are we able to remember the whole sentence that a friend has just uttered, when it consists of dozens of individual chunks in the form of letters?
Memory in psychology pdf
The results showed that participants were better able to recall memories when the scent at the time of encoding matched that at the time of recall Cann and Ross, A sight or sound that we might find interesting captures our attention, and our contemplation of this information - known as rehearsal - leads to the data being promoted to the short-term memory store, where it will be held for a few hours or even days in case we need access to it. In , Craik and another psychologist, Endel Tulving, published the findings of an experiment which sought to test the levels of processing effect. Nobre, Ian A. These findings suggest that a link between our sense of smell and memories remains, even if it provides less of a survival advantage than it did for our more primitive ancestors. The authors suggest that selective attention during the maintenance of a memory can turn it from one that is relatively weak into one that is more robust, which allows for access to information that would otherwise be forgotten. Interference Interference theory postulates that we forget memories due to other memories interfering with our recall. In the third study, ravens and humans are tested in a series of novel working memory tasks, completed individually or with a competing partner. When you are given a new schedule a few months later, you may find yourself adhering to the original times. After the trigrams had been shown, participants were asked to count down from a number, and to recall the trigrams at various periods after remembering them. In a situation such as an bank robbery, you may have other things on your mind besides memorizing the appearance of the perpetrator. Attention, working and long-term memory work in concert to harness the flow of information, and to support rapid and flexible adaptation to the changes in the environment.
Researchers sent participants on a self-guided tour of a museum with a camera that automatically took pictures of their visit. The use of framed questions, as demonstrated by Loftus, can retroactively interfere with existing memories of events.
Cognitive psychologist Elizabeth Loftus has spent much of her life researching the reliability of our memories; particularly in circumstances when their accuracy has wider consequences, such as the testimonials of eyewitness in criminal trials.
James Coan demonstrated that false memories can even be produced of entire events. The cue was placed at the location of the item valid retro-cue or around the central cross neutral retro-cue.
On half the trials, participants saw a cue indicating which arrow would be tested.

The booklet given to his brother contained a false account of him being lost in a shopping mall, being found by an older man and then finding his family. This model suggested that information exists in one of 3 states of memory: the sensory, short-term and long-term stores. These findings suggest that a link between our sense of smell and memories remains, even if it provides less of a survival advantage than it did for our more primitive ancestors. Well-developed perceptual systems provide a continuous flow of abundant and up-to-date According to this model, memories do not reside in 3 stores; instead, the strength of a memory trace depends upon the quality of processing, or rehearsal, of a stimulus. Participants were shown a list of 60 words, which they then answered a question about which required either shallow processing or more elaborative rehearsal. This supported the concept of retroactive interference: the second list impacted upon memories of words from the first list. But how has this evolutionary advantage survived in modern-day humans? When many people learned that JFK, Elvis Presley or Princess Diana died, or they heard of the terrorist attacks taking place in New York City in , a detailed memory seems to have formed of what they were doing at the particular moment that they heard such news. Only through sustained effort of rehearsing information are we able to memorize data for longer than a short period of time. Whilst viewing the slides, the participants were exposed to pleasant odor of aftershave or an unpleasant smell.
