Typically survey pretesting involves separate timelines and research staffs for cognitive and usability testing. In this paper, we make the case that a more comprehensive and less labor-intensive approach to pretesting is to conduct both cognitive and usability testing concurrently. By testing the same questionnaire concurrently with respondents and interviewers (the users in this case), potentially problematic question wording and instrument design can be more efficiently identified in a way that can be used to improve the questionnaire for both the respondent and the interviewer. In 2005 and 2006, the U.S. Census Bureau conducted separate rounds of cognitive and usability testing on an interviewer-administered non-response follow-up questionnaire in preparation for the 2010 Census. The usability testing was conducted in the Census Bureau’s Usability Lab with an early version of the instrument. Later, the Census Bureau’s Cognitive Lab conducted cognitive testing of the instrument. In doing the testing separately, we learned that in addition to usability issues, usability testing also identifies question wording issues, but that usability staff does not have the specialized experience (or sometimes the authority) to make recommendations in that arena. Similarly, while examining question wording, cognitive testing also identifies poor usability features, but the cognitive-testing staff lacks the experience with such testing to be able to recommend improvements in usability features. Based on this observation, in 2008, the Cognitive and Usability Labs at the Census Bureau conducted 40 cognitive and 20 usability interviews concurrently and in conjunction to test the questionnaire and presented results and recommendations from both types of testing together. When testing is conducted concurrently, staff from both labs, representing both specialties, can be at the table at once, creating a more efficient methodology. By examining these two case studies, this paper will discuss what can be gained by conducting these studies in concert above and beyond conducting them independently. Examples of the kinds of findings that are possible through this joint research and the synergy from having both research teams involved will be described.

The point location problem is to determine the position of n distinct points on a line, up to translation and reflection by the fewest possible pairwise (adversarial) distance queries. In this paper we report on an experimental study of a number of deterministic point placement algorithms and an incremental randomized algorithm, with the goal of obtaining a greater insight into the practical utility of these algorithms, particularly of the randomized one.

Point Placement Algorithms: An Experimental Study

This paper presents the results of a study investigating the impact of participant personality on usability testing. Data were collected from 20 individuals who participated in a series of usability tests. The participants were grouped into 10 introverts and 10 extroverts, and were asked to complete a set of four experimental tasks related to the usability of an academic website. The results of the study revealed that extroverts were more successful than introverts in terms of finding information as well as discovering usability problems, although the types of problems found by both groups were mostly minor. It was also found that extroverts spent more time on tasks but made more mistakes than introverts. From these findings, it is evident that personality dimensions have significant impacts on usability testing outcomes, and thus should be taken into consideration as a key factor of usability testing.
