Heavy Smartphone Use Linked to Lower Intelligence

University of Waterloo (03/05/15) Wendy Philpott

New research from the University of Waterloo suggests a link between heavy smartphone use and lower intelligence. The study suggests smartphone users who are intuitive thinkers, or who depend on gut feelings when making decisions, frequently use their device's search engine rather than their own brainpower. "They may look up information that they actually know or could easily learn, but are unwilling to make the effort to actually think about it," says University of Waterloo researcher Gordon Pennycook. In contrast, analytical thinkers second-guess themselves and solve problems in a more logical way. Highly intelligent people are more analytical and less intuitive when solving problems. In three studies involving 660 participants, the researchers examined various measures, such as cognitive styles ranging from intuitive to analytical, in addition to verbal and numeracy skills. They also examined participants' smartphone habits, and found individuals who demonstrated stronger cognitive skills and a greater willingness to think in an analytical way spent less time using their smartphones' search engine function. The researchers suggest when people avoid using their minds for problem-solving, it may have adverse consequences for aging.

Time to Disconnect: Why the SIM Card Has Had Its Day

The Conversation (03/05/15) Markus Kuhn

SIM cards used by mobile phones to connect to phone networks will soon be 25 years old, and have been found to be vulnerable, writes University of Cambridge senior lecturer Markus Kuhn. British and U.S. intelligence agencies reportedly stole millions of SIM card security keys, enabling spies to track users and listen in on calls. Kuhn says SIM technology could have been replaced some time ago with a simpler alternative--typing in a user identifier and password directly into the phone, similar to how Wi-Fi is accessed. Quick Response (QR) codes also could be a convenient alternative for smartphones with cameras, where an app could read the details encoded in the QR via the camera. Modern cryptographic techniques such as password-authenticated key exchange enable passwords as simple as a five-digit PIN to create highly secure encrypted connections. Network operators would be opposed to eliminating SIM cards, which enable them to lock in customers to their network. However, Kuhn says today's Internet-based telephony has demonstrated that moving a telephone number between networks can be accomplished in seconds, and the same should be implemented in mobile phone networks. The European Commission has long tried to improve mobile phone competition, and Kuhn says abandoning the SIM would be a major step toward this goal.

Addressing the Human Brain's Big Data Challenge With BrainX3

Pompeu Fabra University (Spain) (03/04/15) Xerxes D. Arsiwalla

Researchers at Pompeu Fabra University's Synthetic Perceptive, Emotive, and Cognitive Systems (SPECS) lab have developed BrainX3, a platform for visualizing, simulating, analyzing, and interacting with massive amounts of data. BrainX3 combines computational power with human intuition in representing and interacting with large complex networks. The platform serves as a hypothesis generator of big data. The team has used BrainX3 to reconstruct a large-scale simulation of human brain activity in a three-dimensional virtual reality environment, including the neuronal activity of the entire cortex in the resting state. Users can interact with BrainX3 in real time, while the immersive mixed and virtual reality space enables users to explore and analyze dynamic activity patterns of brain networks both at rest and during tasks, or for finding signaling pathways associated with brain function and/or dysfunction or as a tool for virtual neurosurgery. The researchers also have simulated neural activity from lesioned brains and activity resulting from transcranial magnetic stimulation perturbations. The data on brain activity in these states could be used to assess levels of consciousness in patients with severe brain injury.

How Big Data Can Be Used to Understand Major Events

University of Bristol News (03/04/15)

A paper by researchers at the University of Bristol describes their use of big data analytics to understand and characterize the media coverage of the 2012 U.S. presidential election. Academics from the university's Intelligent Systems Laboratory (ISL) analyzed more than 130,000 online news articles using a big data system featuring new methods that are richer than traditional word-association networks. The researchers used a semantic graph that linked a given text to identified noun phrases and verbs, using the resulting subject-verb-object triplets as the basis for a word-association network. The researchers note this method has never been used with such a large real-world dataset, and employing it enabled them to show, for example, that Democrats presented a more united front on policy issues, while Republicans were divided on several issues. "Mapping the full electoral campaign coverage by offline and online media is a very difficult challenge, given the large amount of data and the large number of sources available in advanced democracies," says ISL's Saatviga Sudhahar. "We believe that the methodology used for the study is a big step forward in the linguistic analysis of texts by using extracted relational data and could help us understand major events."
