3 AI Habits That Can Change How You Organize Your Work Week
Forbes online

Nor should you just be expected to focus all day, non-stop. “We can’t expect to lift weights nonstop all day, and we can’t expect to use sustained focus and attention for extended periods of time, either,” Gloria Mark, a professor of informatics at the University of California, Irvine, told the New York Times.
Smartphones and Social Media May Be Shrinking Our Attention Spans

Gloria Mark [UC Irvine professor emeritus ICS] studies people's attention and behavior while using digital devices. Her research has found a significant decline in the amount of time people remain focused on screens. … "It's a combination of offloading our memories to our devices as well as just spending less time focusing on any one thing that's making it hard for people to learn."

Gloria Mark, a researcher at UC Irvine who has studied digital distraction for over two decades, found that after a single interruption it takes an average of twenty-three minutes to fully return to the original task. The ability to sit with one thing for ninety minutes without reaching for something else used to be ordinary. Now it’s rare enough to be a competitive edge.
Digital habits that rob attention and energy — and how to combat them

I've spoken to researchers, like Gloria Mark at University of California, Irvine, who have studied how we switch our attention. One of the things she has seen is that if you've spent an hour switching from screen to screen, checking X, then Instagram and going over to email, even if in the next hour everything calms down and you want to sit down with a single article, you will start switching tasks yourself. So even if nobody else is interrupting you, you will start interrupting yourself.
The No. 1 way Americans spend their free time: It’s ‘always been a huge part’ of our culture
CNBC online

Gloria Mark, a chancellor’s professor of informatics at the University of California, Irvine …. believes the fast-paced nature of both traditional media and short-form content has negatively affected people’s attention spans, which can affect stress levels as well as quality of performance on an activity. When you’re trying to figure out what to do in your leisure time, “you can read books, you can walk in nature, you can play sports, you can have conversations with people,” she says. “Those things require us to have longer periods of attention.”

Understanding smartphone usage in college classrooms: A long-term measurement study
Computers & EducationInyeop Kim, Rihun Kim, Heepyung Kim, Duyeon Kim, Kyungsik Han, Paul H Lee, Gloria Mark, Uichin Lee

Smartphone usage is widespread in college classrooms, but there is a lack of measurement studies. We conducted a 14-week measurement study in the wild with 84 first-year college students in Korea. We developed a data collection and processing tool for usage logging, mobility tracking, class evaluation, and class attendance detection. Using this dataset, we quantify students' smartphone usage patterns in the classrooms, ranging from simple use duration and frequency to temporal rhythms and interaction patterns.
The Perpetual Work Life of Crowdworkers: How Tooling Practices Increase Fragmentation in Crowdwork
Proceedings of the ACM on Human-Computer InteractionAlex C Williams, Gloria Mark, Kristy Milland, Edward Lank, Edith Law

Crowdworkers regularly support their work with scripts, extensions, and software to enhance their productivity. Despite their evident significance, little is understood regarding how these tools affect crowdworkers' quality of life and work. In this study, we report findings from an interview study (N=21) aimed at exploring the tooling practices used by full-time crowdworkers on Amazon Mechanical Turk.

We describe a controlled experiment, aiming to study productivity and stress effects of email interruptions and activity interactions in the modern office. The measurement set includes multimodal data for n = 63 knowledge workers who volunteered for this experiment and were randomly assigned into four groups: (G1/G2) Batch email interruptions with/without exogenous stress.

Several psychologists posit that performance is not only a function of personality but also of situational contexts, such as day-level activities. Yet in practice, since only personality assessments are used to infer job performance, they provide a limited perspective by ignoring activity. However, multi-modal sensing has the potential to characterize these daily activities. This paper illustrates how empirically measured activity data complements traditional effects of personality to explain a worker's performance.

Personal visualizations present a separate class of visualizations where users interact with their own data to draw inferences about themselves. In this paper, we study how a realistic understanding of personal visualizations can be gained from analyzing user interactions. We designed an interface presenting visualizations of the personal data gathered in a prior study and logged interactions from 369 participants as they each explored their own data.
