  1. Marked by a teacher

    To retain recall, which is more beneficial, rote rehearsal or imagery?

    4 star(s)

    their experiment consisted of giving participants three-consonant trigram etc. Miller (1956) used a memory span procedure to test how many items participants could hold in STM. He concluded that the average number was seven items. Hence the phrase Millers magical number seven give or take two.

  2. Memory: Rote Rehearsal and Mental Imagery.

    As even though generally participants did better using imagery there were still some participants who did not, so it would be interesting to explore if other methods of recall are even better then memory Also I could use a much bigger participant sample, as this would allow mw to generalise my findings.

  1. Report on Psychological Research into Eyewitness Testimony

    such as interrupting the witness whilst they were recalling information.15 Other methods sometimes used include hypnosis. It was widely believed that hypnosis may help witnesses to relive the experience of the incident and so produce better recall performance; however studies carried out have offered opposing evidence. Orne et al (1984)

  2. Does chunking help with memory?

    The task takes place in the recreational centre in the college. This is in the participants own settings rather than in a laboratory. This should reduce the stress and pressure of the situation and promote natural behaviour.

  1. Investigation into acoustic and visual encoding in short-term memory

    when information is presented visually, this links into be the experimental hypothesis. Displacement and decay are the theories associated with this research. However the null hypothesis suggests there will be no significance or difference in participants using acoustic coding in STM and when information is presented visually to them.

  2. A counselling Interview

    To enhance the dynamic of our working relationship I briefly explained the Egan Model of therapy, its structure and potential aims. However I felt that upon reflection, that this confused, rather than highlighted the positives of the technique. Although it did not appear to hamper Lee's willingness to participate, I


    Most of the time you do not even notice it but with the Necker cube your brain realises there are two distinct hypotheses of what it is looking at - both equally likely and the brain simply has no way of deciding which is the most right.

  2. Recall in Memory Using Mnemonics

    My hypotheses will reflect this. The null hypothesis is used to predict no difference in the two groups, and any difference will be due wholly to chance factors. The experimental hypothesis will be one tailed (directional) I chose this as previous research seems to point towards the fact that mnemonics improve recall.
