Abstract

ABSTRACT NAME OF INSTITUTION: De La Salle University-Dasmariñas ADDRESS : 4115 Dasmariñas, Cavite TITLE : The Effects of Monosodium Glutamate on Short-term Memory Recall Performance AUTHORS : Garces, Jenna B. Miyagawa, Maria Rhodora H. FUNDING Parents SOURCE: RESEARCH COST: P 5,000 DATE STARTED: June 2007 DATE COMPLETED: March 2008 OBJECTIVES OF THE STUDY: A. GENERAL To ascertain whether Monosodium Glutamate has an effect on the short-term memory recall performance of first and second year students of De La Salle University-Dasmariñas. B. SPECIFIC 1. To determine the mean score in the short-term memory recall performance of the subjects with and without MSG. 2. To know if there is a significant difference in the short-term memory recall performance among the subjects with and without MSG. SCOPE AND LIMITATIONS The over-all purpose of this study was to determine the effects of Monosodium Glutamate on short-term memory recall performance with the help of a Consonant-Vowel-Consonant (CVC) recall test. METHODOLOGY The study utilized the Analysis of Variance, One Way Between- Within subjects design. MAJOR FINDINGS The researchers conducted the study to find out the effects of Monosodium Glutamate on short-term memory recall performance through the use of a CVC test. The subjects were 80 students of De La Salle University- Dasmariñas who took up introductory classes in Psychology. Simple Random Sampling, specifically the “Fish Bowl Method” was used to determine the sample population since this technique gives each subject the same probability of being chosen at any stage during the sampling process. 1. What is the mean score in the short-term memory recall performance of the subjects with and without MSG? The placebo group (without MSG) obtained a mean score of 10.00 while Treatments one (1) (1.2 g), two (2) (2.0 g), and three (3) (2.4 g) acquired mean scores of 10.45, 11.05, and 8.40 respectively (See Figure 1). 2. Is there a significant difference in the short-term memory recall performance among the subjects with and without MSG? At 0.05 level of significance, the f computed value of 2.84 was higher than the f tabulated value of 2.72 (See Figure 3). Thus rejecting the hypothesis; it was found out that there is a significant difference among the subjects in the experimental (with MSG) and control group (without MSG). It was also assumed that when MSG was utilized in normal levels, the recall performance of the subjects was enhanced whereas those who consumed 2.4 grams of MSG exhibit difficulties remembering CVCs (See Figure 1). CONCLUSIONS Based from the results gathered, it was then deduced that: 1. There are flavor enhancers that could affect not just the food but also those who consume the said substance; one of these is Monosodium Glutamate, which is the most widely used flavor enhancer. 2. Monosodium Glutamate can increase short-term memory recall performance if consumed lower than the normal gram. As the gram of MSG increases up to the normal gram (2 g.) a person can consume everyday recommended by the World Health Organization (WHO), the higher the probability that the short-term memory recall performance increases. 3. Monosodium Glutamate has a negative effect on short-term memory if it was consumed in doses higher than the normal amount (2 g./day) a person should consume. RECOMMENDATIONS Researchers 1. It was recommended that higher levels of Monosodium Glutamate be used in measuring the effects of it on short-term memory recall performance. 2. The means of ingestion may be altered. For example, instead of using plain water for the subjects to drink, a researcher may use soup. 3. A larger population may be used for the results to be further validated. 4. The intelligence quotients (IQ) of the subjects may be measured to counter validate the results. 5. A pre-test may be given before the ingestion of MSG, and then posttest with a different set of CVC for further validation. Students 6. Students must be very careful of the kind of foods that they eat. It might contain large amounts of MSG that might affect their memory. Parents 7. Mothers should be careful of using too much MSG as a flavor enhancer when they cook meals since it might cause negative effects to the family members. Public Servants 8. Health officials must do something to advertise the negative effects of MSG. They must also promote programs regarding the matter. 9. The government must support the programs of local officials in developing the awareness of the people.
