The research tested the basic question: would processing the same information on a digital versus non-digital platform affect "construal levels"-- the fundamental level of concreteness versus abstractness that people use in perceiving and interpreting behaviors, events and other informational stimuli. In order to study the basic question of whether processing the same information on one platform or the other would trigger a different baseline "interpretive lens" or mindset that would influence construals of information, the research tried to hold as many factors as possible constant between the digital and non-digital platforms. Reading material and other content for the study for example, was published using the same print size and format in both the digital and non-digital (print) versions. The research was composed of four studies that evaluated how information processing is affected by each platform. A total of more than 300 participants, ages 20 to 24 years old, took part in the studies, which were composed of 60 to 100+ participants.

Reading comprehension and problem solving success were affected by the type of platform used. Highlights from the studies include the following:

• Participants were asked to read a short story by author David Sedaris on either a physical printout (non-digital) or in a PDF on a PC laptop (digital), and were then asked to take a pop-quiz, paper-and-pencil comprehension test. For the abstract questions, on average, participants using the non-digital platform scored higher on inference questions with 66 percent correct, as compared to those using the digital platform, who had 48 percent correct. On the concrete questions, participants using the digital platform scored better with 73 percent correct, as compared to those using the non-digital platform, who had 58 percent correct.
• Participants were asked to read a table of information about four, fictitious Japanese car models on either a PC laptop screen or paper print-out, and were then asked to select which car model is superior. Sixty-six percent of the participants using the non-digital platform (printed materials) reported the correct answer, as compared to 43 percent of those using the digital platform.
• Triggering a more abstract mindset prior to an information processing task on a digital platform appeared to help facilitate a better performance on tasks that require abstract thinking. Specifically, 48 percent of participants reported the correct answer to the Japanese car judgement task after completing a priming activity intended to activate a high-level of construal in which they were tasked to take on an abstract mindset, as compared to the 30 percent, who answered correctly without the priming activity.

The research was conducted by Dartmouth's Tiltfactor lab, an interdisciplinary innovation studio that designs and studies games for social impact, and was led by Geoff Kaufman, an assistant professor at the Human-Computer Interaction Institute at Carnegie Mellon University, who was a postdoctoral researcher in psychology at Tiltfactor at the time of the study; and Mary Flanagan, Sherman Fairchild Distinguished Professor in Digital Humanities at Dartmouth and founding director of Tiltfactor.

"There has been a great deal of research on how digital platforms might be affecting attention, distractibility and mindfulness, and these studies build on this work, by focusing on a relatively understudied construct," said Geoff Kaufman. "Given that psychologists have shown that construal levels can vastly impact outcomes such as self-esteem and goal pursuit, it's crucial to recognize the role that digitization of information might be having on this important aspect of cognition," he added.

The study on digital versus non-digital platforms was prompted by earlier research by the co-authors, which revealed that players of the digital version of the public health strategy game, "POX: Save the People®," were more inclined to respond with localized solutions, rather than looking at the big picture.

"Compared to the widespread acceptance of digital devices, as evidenced by millions of apps, ubiquitous smartphones, and the distribution of iPads in schools, surprisingly few studies exist about how digital tools affect our understanding -- our cognition. Knowing the affordances of digital technologies can help us design better software," said Mary Flanagan. "Sometimes, it is beneficial to foster abstract thinking, and as we know more, we can design to overcome the tendencies -- or deficits -- inherent in digital devices," added Flanagan.
