Day9:“Introduction to experimental methods,” “The data collection,” and “Experimental study design.”1/17/2019 The main process of psychology is to design research, data collection, and analysis. Data collection is an important step in psychology. There is three-way of data collection which is observation, self-report, and automatic acquisition. Observation has three methods which are the visual method, the acoustic method, and the biometrics method. The scientists use all kinds of machines to collect their observations. Self-report is introspection. Social desirability often affects self-report a lot. Automatic acquisition through facebook, twitter, and Instagram automatically collect data which can be used for psychology research. The data of the company, the government, and the statistics can all be used for psychology. The standardization of the birth of modern psychology is the setup of the lab for experiments. Therefore, setting up an experiment while designing research is necessary for psychology research. Dr. Peng provides an example. He likes to drink orange juice. Dr. Peng feels more active and positive every time he drinks orange juice. Therefore, he thought if orange juice can provide positive feelings for a human. Dr. Peng observed his friends who drink orange juice and found that his friends who drink organic juice did look positive. However, this result is not accurate because the size of respondents and the rules of data collection are not regulated. Experiments and researches require rigorous process and accurate collections. I need more basic knowledge to support my works for the lab. Video coding is one of the steps in data analysis. The purpose of video coding is selecting the important parts of the experimental video which is preparing for the further analysis. I believe that I can understand my works better with more professional knowledge.
