The Influence of Task Types on User Experience after a Web Interface Update
1 like121 views
The document explores how different task types affect user experience following an update to a web interface. Key findings indicate that repeated visits to the new interface can reduce cognitive load but have varying effects on emotional arousal and valence depending on whether the task is informational or transactional. The research suggests the need for ongoing qualitative insights and highlights the importance of task categorization in understanding user interactions with digital products.

- 9. No Hypotheses Results H1 Repeated visits to the new interface reduces cognitive load Supported H2 Repeated visits to the new interface reduces emotional arousal. Not supported H3 Repeated visits to the new interface increases emotional valence. Not supported H4 The task type moderates the relationship between the repetition of tasks on the new interface and cognitive load. So repeated visits will have less of an impact on reducing cognitive workload in the case of an informational task, than in the case of a transactional task. Supported H5 The task type moderates the relationship between the repetition of tasks on the new interface and emotional valence. So the increase in valence will be greater during the initial visits for an informational task as compared to a transactional task. Supported H6 The task type moderates the relationship between the repetition of tasks on the new interface and emotional arousal. So the decrease in arousal will be lesser during the initial visits for an informational task as compared to a transactional task. Not supported Summary of findings
- 10. Implications Support for the role of cognitive scripts in UX • Reduce cognitive load • Link between mental models and task analysis Unexpected spike in emotional arousal with repeat visits • Need for qualitative insights • Valence unaffected, as expected Effects of repeated web/I.S. use vary by task type • Extends limited prior research on the role of task type (JMIS 2005; JAIS 2014) • Future research in Use Continuance
