TL;DR: The 9-item ATI scale, an economical unidimensional scale that assesses ATI as an interaction style rooted in the construct need for cognition (NFC), achieves good to excellent reliability, exhibits expected moderate to high correlations with geekism, technology enthusiasm, NFC, self-reported success in technical problem-solving and technical system learning success, and also with usage of technical systems.

TL;DR: Correlational analyses showed that intensity of tracker usage and data interaction, current physical activity, and tracker acceptance were related to specific abandonment reasons, and abandonment due to perceived data inaccuracy/uselessness and loss of tracking motivation were linked to negative attitudes towards personal quantification.

TL;DR: The notion that quantified feedback of gamified systems can create a dependency that can harm motivation, which becomes apparent through activity reduction when the tracker is not available is examined.

TL;DR: Empirical evidence suggests a need for updated guidelines for designing latency in HCI, particularly on the lower boundary latencies below 100 ms, even though smaller latencies have been shown to be perceivable to the user and impact user performance negatively.

TL;DR: A pronounced diversity of reasons for (not) using nutrition apps indicating that there is no “one-size-fits-all” approach for uptake and prolonged use of nutrition aps, and tailoring nutrition apps to needs of specific user groups seems promising for increasing engagement.
