The superior recall of items at the start of the list is called the primary effect, whilst the superior recall of the items at the end of the list is called the recency effect. This is good evidence for the multi-store model of memory because it shows the difference between the STM and the LTM. Rundus & Atkinson (1970) Rundus and Atkinson asked participants to rehearse out loud the list they were given (similar to Murdock's experiment). Tape recordings showed that words from the beginning of the list were more likely to be rehearsed than later ones. Because of the limited capacity of the STM, words from the middle of the list are thought to be lost completely or unavailable for recall.
Research supporting the working memory model can be seen in Baddeley, Thomson and Buchanan’s research in 1975 of the phonological loop. Their research saw participants recalling one word at a time, of varying lengths. They found that performance was superior in short words (monosyllabic), rather than polysyllabic words. This shows that the capacity of the phonological loop is determined by the length of time it takes to say the words to yourself rather than the number of items. So there are some confounding variables that can alter your ability to remember some words, rather than just rehearsal, or attention, as suggested in the multi-store memory model.
There does not seem to be a particular change type that is easiest or most difficult to spot in both conditions, however in MI, location appears to take a lot longer to spot than colour and presence (mean location=16293.25 compared to colour= 9486.44 and presence= 113.96.13) Mauchleys test of sphericity was found to be non-significant (F=0.931p>0.05) therefore spherificity was assumed. The ANOVA test shows a significant effect of the Interest (F= 83.079 p<0.001), Change Type (F= 5.406 p <0.05) and a significant effect of Interest and Change Type (F=13.094 p<0.001). The dependant T-Tests shows a significant effect of interest (central vs marginal) on response times for colour (t = -3.25, df = 15, p< 0.05) for location, (t = -9.9, df=15, p<0.01) and for presence, (t = -6.23, df = 15, p<0.01). Therefore the hypothesis must be accepted and the null hypothesis rejected as there response times were faster in the CI than the MI with all 3 types of change.

Hitch and Baddley showed support for the WM by conducting an experiment where they gave participants two tasks to do at the same time. They found participants were slower completing these tasks when a task involved using both the central executive and the articulatory loop. This shows that you can't use two componants of the STM at the same time. Shallice and Warrington also showed support for the WM in the casestudy of a brain damage patient KF. The study showed that short term forgetting of auditory information was much greater than that of visual stimuli and his auditory
Willingham states that primary memory is limited to 2 seconds of acoustic code and four visuospatial objects. Semantic-based memory is not as limited because it utilizes a process known as “chunking.” Chunking in a process that increases the capacity of primary memory by having the secondary memory doing the translating, or encoding, using semantics. The reason that Primary memory is temporary is because interference and decay effect what can be stored in that area of the brain at one time. Any damage or factors that would prohibit the Primary Memory storing information effect that future or past memories have on the current information stored in primary memory. Decay is the biggest interference to the ability of Primary Memory and limits its capacity and the required attention to retrieve information.
There are 2 types of memory: short term and long term. What did the results show? Did your data support your hypothesis? Why are nonsense syllables often used in memory research rather than actual words? Nonsense syllables do not stand for abbreviations and has no meaning therefore participants cannot relate to the word.
He/she showed that though their short term memory was damaged or quite poor when it came to preforming verbal tasks, they were still able to perform visual tasks, indicating separate stores for visual and verbal task as suggested by the working memory model. Brain scans can also show physiological support indicating that separate stores of memory are used for different types of tasks as different parts of the brain are used for verbal and visual data based information, as suggested by the working memory model. Another positive remark about the working memory model is that it is more plausible and realistic compared to the multi-store model as it suggests that the stm holds our information in ties with manipulation due to problems that maybe encountered unlike the multi-store model that claims the stm is a static store with its fixed duration and capacity rate that may be little affected. The working memory model gives more in-depth information about the short term memory store in contrast to the multi-store model. On the other hand, the working memory model has been hugely criticised for not being a comprehensive model of memory as it only concerns itself with the short term
He also states that the Top-down processes override sensory or bottom-up information. People think that sights, sounds, and touch from the outside world constituted reality. But the brain constructs what it perceives based on past experience (Kossyln 2006). "Doctors Oakley and Halligan researched the effects of neutral hypnosis. Neutral hypnosis is when a person is hypnotized before any hypnotic suggestions are given.
The converse has been found to be true as well: Instructional strategies that appear to slow the learner's progress during training often lead to better post training or transfer performance. For example, many studies have shown beneficial effects of random over blocked practice on transfer of learning, even though blocked practice often leads to better performance during the training session. In a 2 × 3 factorial experiment (N = 120), with the factors practice schedule (random, blocked) and critical thinking prompts (before task, after task, none), this study investigates whether this also applies to complex judgment tasks and whether critical thinking prompts can enhance the effectiveness of particular practice schedules. It is hypothesized that prompts provided after task execution yield best transfer in a random practice schedule, whereas prompts provided before task execution yield best transfer in a blocked schedule. In line with this hypothesis, a blocked schedule led to better performance than random practice during training but not on the transfer test, where a random schedule was beneficial.
A flicker paradigm occurs when an original and a modified image continually alternate, one after the other, with a brief blank field between the two. This study consisted of measuring reaction time based on presenting a flashing stimulus then either changing the stimulus with one of the independent variables; with a color-presence- location change or placement change, centrally versus marginally. The study also consisted of measuring whether reaction time was quicker or slower based on these changes occurring centrally or marginally. Based on the idea that visual acuity is good only in small area straight ahead, where the image is focused on a part of the retina called the fovea (St. James, Schneider, & Eschman, 2005), I predicted that reaction time would be quicker when the change was located centrally within the
