School of Humanities and Social Science Division of Social Science 193 Division of Social Science The Development of Information Updating in Working Memory Supervisor: CHENG, Chen / SOSC Student: JIANG, Hanyu / GCS-SOSC Course: UROP1100, Spring Working memory, an extensive and intriguing theme of the cognitive aspect of psychological development, has been investigated by scholars for decades. This semester, the UROP project “The Development of Information Updating in Working Memory” led by Professor CHENG, Chen, has been focused on various aspects of working memory as well, including visual and arithmetic aspects of working memory. My role and gains in this project, which are the main contents of this progress report, is composed of studies and research. The report will first discuss the major studies of this semester, including the experimentation for intuitive arithmetic of adults and some preparation work for the working memory study and the rainbow game study. Then the research findings from the analyses of a dozen existing research papers on the topic of proenvironmental behaviors and attitudes will be introduced. The Development of Information Updating in Working Memory Supervisor: CHENG, Chen / SOSC Student: MUI, Pui Ka / QSA Course: UROP1000, Summer The project aims to figure out whether and how adults’ arithmetic skills are affected by their approximate number system (ANS) precision in estimating the numerosity of sets of of dots, and the role of temporal variation (the duration of the process, whether is in the iconic memory or the working memory) in encoding and symbolic arithmetic ability in the process. In the summer term, I conducted an experiment to investigate the relationship between the temporal variation in encoding and ANS representational precision in estimating solutions between different manipulations (comparison vs. addition), especially in how fast adults can retrieve the numerical information with a brief visual display and varied the visual presentation with different duration. In this progress report, I illustrated the literature review from 3 journal articles, and reported the method and procedure of the ANS experiment I conducted during my UROP training period. The Political Economy of Conflict and Elections Supervisor: HENDRY, David James / SOSC Student: CHO, Young Beom / QSA Course: UROP1100, Summer This research progress report delves into the impact of the Voting Rights Act's language minority provisions on voting decisions within the United States, with an emphasis on Spanish-language translations of ballot measures. Utilizing a regression discontinuity (RDD) design, the project examines the influence of Spanishlanguage ballots on voter turnout and election outcomes at the precinct level. The methodology encompasses comprehensive data collection and preprocessing, employing Python libraries such as NumPy and Pandas for data manipulation. The report delineates the progress achieved, including updates on data availability, cleaning, transformation, and the challenges encountered, such as inconsistencies in precinct information and complexities in state ballot questions. The report also explains further tasks which needs to be done for the research.
