The Effects of Expectations on Subjective Fluency in Intuitive Interactions
Description/Abstract/Artist Statement
Three main indices of an intuitive interaction are: high effectiveness (ability to complete the task), low cognitive effort (requires minimal critical thinking), and strong positive subjective fluency (interaction felt familiar and effortless). This study is designed to determine if expectations have a significant impact on a user’s rating of subjective fluency during an interaction. Subjective fluency refers to the judgments we make about an interaction regarding how easy it is to process the information presented (perceptual fluency) and how straightforward the interaction is (interaction fluency). In this study, objective fluency was manipulated by having pages of high/low perceptual and interaction fluency. Participants also experience an expected fluent or disfluent situation. This expected fluency was manipulated by telling participants they would search English websites (fluent) or they would search Dutch websites (disfluent). During the experiment, participants search nine websites with the goal of finding a specific piece of information. Time to complete the search is recorded as well as the accuracy of their search (did they find the information). After each trial, participants rate that page’s ease of use and the subjective effort needed to complete the task. It is expected that perceptually and interactively disfluent webpages (difficult to read font and unconventional pop-ups, respectively) will be rated as more difficult to use. In addition, it is expected that believing the interaction will be difficult (e.g., those in the Dutch condition), will lead them to rate all interactions as more difficult even when they objectively are not.
