Getting distracted by irrelevant information and thus being interrupted in an ongoing task is an omnipresent situation in daily life. In particular in applied task settings, a variety of interfering factors occupies the limited cognitive resources. My existing research focuses on related effects in mobile task scenarios and multimedia learning contexts and employs both experimental research and computational cognitive modeling.
Attention distraction in multimedia learning (2012)
My first project in this area of research focused on constraints arising from impaired attention in multimedia learning settings. In a task on factor analysis, attention impairments were included by distracting system-notifications, e.g., update messages, and interesting but irrelevant (so-called “seductive”) text passages that are used to foster motivation. Both features have a high prevalence in computer-based learning environment. To assess learners’ individual level of attention control, I used the FAIR-2, a standardized psychological attention inventory. The results showed that irrelevant information extended the learning time. Furthermore, learners with higher levels of attention control could cope better with system-notifications and achieve increased learning performance.
Interruption and resumption in a Smartphone task (2013-2014)
In a second project, I used a shopping list application to investigate cognitive processes related to interruption and resumption in a real-world scenario. Interruptions occurred due to product advertisement, and task difficulty was increased when shopping had to be done for more than one person. On methodological accounts, I used the cognitive architecture ACT-R to develop a computational model of underlying cognition and validated the emerging pattern with human experimental data. In particular the final product recall indicated a good fit between model and human data. Future directions involve the exploration of beneficial resumption strategies for different user groups and situations to incorporate them in assistive systems.
Can hyperlinks interrupt schema acquisition? (2016-2017)
Hyperlinks became indispensable in our digital age and are an inherent feature of many computer-based learning environments. On the positive side, they can foster deeper understanding, but on the negative side they might also impair the construction of coherent mental models. To explore this duality further, we investigated selected hyperlink features with interrupting potential. In more detail, we manipulated link loading times, spatial link format and fit between link and learning page contents in a learning task on metabolism and energy generation. Even if we could not observe crucial impairments in performance, the inspected features required increased cognitive resources to compensate for the related demands.
