105. Measuring Intuitiveness: Expected and Experienced Fluency
SessionPoster Session 1
DescriptionSubjective fluency may be a key indicator of intuitive interactions (Reinhardt & Hurtienne, 2023). Even so, the robustness of fluency effects is unclear. This experiment extends subjective fluency research to complex stimuli in a naturalistic task – searching websites for information. It also explores the impact of a priori expectations on experienced subjective fluency (c.f., Jiang & Hong, 2014). Expected interaction fluency was manipulated by telling participants they would search English (fluent) or Dutch (disfluent) websites. Experienced fluency was manipulated using font (fluent – Arial, disfluent – Blackadder). Participants in the Dutch condition expected the interaction to be less fluent than those in English. Expected fluency for both groups increased with task experience. In contrast, no subjective measure of fluency (fluency, subjective ease, NASA TLX) was sensitive to language or font manipulations. There was no interaction with expected fluency. The results call into question the reliability of subjective fluency measures.
