Currently, medical errors are one of the most common causes of death in the United
States (Makary & Daniel, 2016), which includes errors related to look-alike, sound-alike prescription drug name confusion. The use of Tall Man lettering, a text enhancement style that capitalizes the dissimilar portions of words, has been recommended by the US Food and Drug Administration (FDA) as well as the Institute for Safe Medication Practices (ISMP) since 2008 in order to make it easier for healthcare professionals to distinguish and identify two otherwise easily confusable drug names. Research performed on the efficacy of Tall Man lettering and similar text enhancements in successfully differentiating look-alike, sound-alike drug names has thus far been either null or inconclusive. Therefore, it is crucial that further research be conducted in order to provide a path to alleviation by increasing the understanding of the problem, and providing evidence to a clearer solution (Lambert, Schroeder & Galanter, 2015). The objective of the current study was to measure the efficacy of Tall Man Lettering and additional text enhancement strategies through an experiment that replicates some of the previously used methods of research. The current study utilized a repeated measures design. Participants were shown a prime drug name, followed by a brief mask, and then either the same drug name or its confusable drug name pair. They were then asked to identify whether the two drug names presented were identical or different. All of the participants completed a total of four trials representing each condition (regular, Tall Man, Tall Man Bold, highlight) and a practice trial. Overall performance was measured through accuracy and reaction time, which revealed that regular, lowercase text was more effective than any of the other text enhancements, including Tall Man lettering, in quickly and accurately identifying differences in drug names. These results seem to add to the body of inconclusive research on the efficacy of Tall Man lettering and similar text enhancement strategies for reducing drug name confusion. Given the significant impact that drug name confusion errors can have on patient safety, it is imperative that further research be conducted in order to give a more definitive answer of whether text enhancement strategies like Tall Man lettering are helpful in practice.

The relationship between user experience, learning, and psychology is complex. There are many rules and concepts that guide experience design. It is likely that some of the guidance is valid whereas other guidance is not. This explores some of that guidance and evaluates how they are linked to learning. Do the guidance’s made 25, 50, 100 years ago still hold true today? Additionally, the psychological background behind the way someone holds memory is important. Knowing how information is stored and processed helps educators provide the best learning experience possible. With an eye toward perception and cognition, this paper examines the relevance of the various pieces of guidance. The results suggest that, overall, this guidance is still valid and valuable to current learning trends and designs. This suggests that user experience designers for education need to pay attention to the guidance provided by psychology when designing learning management systems, placing content in a course, and choosing which aesthetics to follow.

This paper describes the development of a mobile application aimed at facilitating the communication and collaboration of roommates with regards to grocery shopping, food-sharing, and cost-splitting. The approach involves several methods of user-informed design. First, I conducted an analysis of user needs, interviewing potential end-users to gauge shopping habits and behaviors. Second, using iterative wireframing and a design tool called Figma, I constructed a working prototype of the design. Third, the prototype was used in a usability study, focused on uncovering pain points and other insights regarding the performance of the app. The usability tests were designed to simulate tasks that users might reasonably encounter when using the app. Finally, a second analysis of user needs was conducted, this time on a much larger scale. These methods were used to develop several informed design decisions that could improve the overall usability in future iterations of the design.
