Introduction

Short term memory investigation Nerve cells require up to 24 hours before they can exchange information over new synapses. Abstract: A lot of research has been done to determine whether short-term memory works better in the morning or afternoon. In a study, 16-18-year-olds (sixth form students of Battersea park school) were administered to take part in a word test to assess their short-term memory. Results of this were analyzed. Null Hypothesis: learning in the morning is more effective Alternative hypothesis: learning in the afternoon is more effective. Introduction To learn new things, to store experiences and to adapt to new circumstances - these characteristics of the brain enable us the daily survival . This special flexibility of the brain is reached through constant making and breaking contact between nerve cells. Whenever we learn something, the connections between nerve cells, (synapses) change. At this point, the Axon of a nerve cell and the Dendrite of the neighbouring cell meet. The centre for brain research of the medical University of Vienna is currently involved in two researches that contribute to the clarification of the processes in memory. They had tested the article (of researchers at the Harvard Medical School), which is called a key experiment. ...read more.

studied the effects of both phonological and noise distracters on short term momory recall and showed that both distracters negatively affected the memorization process. The stronger that the distracter was to the material to be memorised than the more severe this effect was. The recency effect is greater for auditory than visually presented material. This is called the modality effects. It has been shown that if an irrelevant item is spoken at the end of a list, the recency effect is reduced for auditory but not for visually presented lists. This is called the suffix effect. Many other factors can adversely affect short term memory recall. For example, Banbury, Macken, Tremblay and Jones (2001) studied the effects verbal distractions on short term memory. The degree of interference was related to the properties of the sound specifically and even quiet background sounds have a negative effect upon recall. The word frequency and the rate of presentation are also influential in short term memory recall as is presentation type. For example Frankish (1985) found that there was a substantial recall advantage for grouped lists with auditory but not with visual presentation. Individuals with defective short terms memory systems have told us a lot about memory and illustrate the need for continued research in this field. ...read more.

    I chose to do the letters test. You are given 10 seconds to remember the list. The next screen pops up and gives you the opportunity to enter the three letters. This process continues for as many sequences you can make it through. The purpose was to go through consecutively recalling the letters.

  2. Investigate into the Primacy and Recency effect

    0.01 Discussion From the results found it can clearly be seen that there is less of a recency effect in the experiment when using an interference task. Futhermore, it can also be seen that there was both a primacy and recency effect in the non-interference experiment.

  1. Primacy and Recency effect

    experiment to show whether participants tend to remember the first few words and the last few words better than the middle words. Hypothesis: one tailed hypothesis The first 10 words of a list of 30 (positioned from 1-10) and the last 10 words (positioned from 21-30)

  2. Investigating the short-term memory

    The obtained result showed that after 18seconds the idea that without rehearsal, the duration of the short-term memory is shorter, therefore causing us to forget. Alan Baddeley (1966) investigated short-term memory. In his study, he investigated the coding of words.

  2. "An experiment to see the effect of chunking on short-term memory recall".

    the experiment and spare paper for the participants to write their answers on. A stop clock was used because this is more efficient and more accurate way for measuring the time. Paper was provided for the participants because this way their paper was clean and new and there would be nothing on the paper that would distract the participants.

  1. The Effects of Chunking and Distraction on Short Term Memory Recall

    For example Frankish (1985) found that there was a substantial recall advantage for grouped lists with auditory but not with visual presentation. One of the other most important factors to influence short term memory recall is that of chunking. The process of chunking was originally defined by De Groot (1956)

    Confidentially is a legal right under the Data Protection Act; this investigation did not record the names of participants; instead used numbers though gender of participants was noted. Participants were given informed consent, allowing participants the right to withdraw if they decide during the experiment that they no longer wish to participate.
