PTC - Thesis Proposal Example As compared to males, the study that was presented by Bartoshuk, Duffy and Miller (1994) strongly suggest that there is a higher taste sensitivity for PTC/PROP among the females. In line with this, Fareed, Shah and Hussain (2012) made a confirmation that there are literally more female PTC tasters as compared to male. Women in general can be classified as taster or non-taster of PTC. Specifically the main purpose of this laboratory proposal is to analyse the PTC threshold of my female classmates. As such, this study aims to answer the question as to whether or not ethnic or racial considerations could somehow affect the ability of women to taste PTC. Likewise, it will also answer whether or not PTC concentration affects the tasters’ and non-tasters’ ability to taste PTC. In other words, the proposed laboratory test will seek to address the following research hypothesis: The laboratory test is composed of two rounds. The first round will require each participant to taste each of the six (6) tasting solution at a lower concentration. The second round will require each participant to taste each of the six (6) tasting solution at a higher concentration. Regardless of age, a total of 20 female students will be invited to participate in the laboratory tests. To learn more about the health status of each participant, each one of them will be requested to check their history of illnesses (i.e. diabetes, COPD, sinusitis, etc.). Prior to test, each of the research participants will be instructed not to smoke, eat, or drink for at least an hour (Hong et al., 2005). In relation to age and ethnic or race, the PTC taster status, taste threshold, and taste recognition threshold will be measured in each participant. As such, participants who are able to recognize the bitterness of PTC solution at a concentration of < 1.80 x 10-4 M will be classified as PTC tasters (Hong et al., 2005). Prior to tasting each sample, each participant will be
