Generally, chunking is helpful in short-term memory retention. INTRODUCTION A study on the effect of chunking on short-term memory retention has been made which concluded that the use of chunking can increase a person’s short term memory. De groot (1946) first introduced this information-processing mechanism with respect to problem solving.It is considered that a collection of elements that are strongly associated with one another is called as a chunk and can be classified as deliberate or automatic (Gobet et al., 2001). According to the research, chunking will help in increasing our ability to memorize things for a longer time. This study is done to find out the difference between memory-retention of people to whom chunking was taught and to whom no chunking was taught. METHOD Design The participants were selected randomly, a total of 2 people with diverse sex and ages. The participants were asked to recall letters they were shown a little while ago.The independent variable being the various letters shown to the people and the dependent variable measured was the short-term memory capacity. Participants There were total of 2 random participants aged between 20-25 years. The both participants are literate enough to understand the seriousness of the study conducted. The consent of participants had been taken prior to the test and had been asked for any vision problems they may have. (No participant was having a vision problem) Materials A consent form (Appendix A). Instructions for participant (Appendix B). Additional instructions for the second participant (Appendix C). List of letters to be memorized (Appendix D). Procedure The Participants were guided as to the objective of the test conducted and provided with a copy of instructions. Appendix B was given to the both participants but Appendix C, that was illustrating the chunking process, was given to only one participant. The participants were given to read and memorize a scattered bunch of letters (Appendix D) for a complete one minute and then told to write down as much letters as they can remember. The test was assessed by giving one mark for every correct answer and zero for every wrong one then a t-test was performed on the results to analyze the findings. RESULTS The mean result of the test conducted is shown below in Table 1. It was discovered that the score is higher in people to whom chunking was taught than the others with the values of 15 and 10 respectively. This endorses the experimental hypothesis which that chunking principle is highly useful in enhancing short-term memory retention.
