As we embrace new technology that does everything but kiss us on the mouth, we risk cutting ourselves off from human interaction. For many, the iPhone has become a best friend, partner, lifeline, companion and, yes, even a Valentine.
"He advocates the technique .... essentially as a form of Lite-Brite phrenology."
DiscourseMarker: WHAT DOES HE THINK AN IPHONE IS USED FOR??!? It's for SOCIAL INTERACTION!!! Maybe people like iPhones (and Blackberries and Droids and regular cell phones) because they help us stay in touch with other people.
People who email the vast majority (80-100%) of their core ties weekly are in phone contact with 25% more of their core ties than non-emailers. Moreover, those who email the vast majority of their significant ties weekly are in phone contact with twice as many of their significant ties than non-emailers.
face-to-face conversations may not always be the rich, deep, and inherently superior means of communication that it is often presumed to be. The quality of face-to-face conversation was rated no higher than telephone calls (in fact, the mean quality of telephone calls was higher, although not significantly so). People having face-to-face conversations were most likely to be engaged in other activities simultaneously. In sum, our studies suggest that, instead of a trade-off between high quality face-to-face conversations and lower quality internet interactions, students are supplementing high quality face-to-face conversations and telephone calls with really good internet interactions. source.
Bennett’s point is that a suite of methods known as multiple comparisons correction can allow researchers to maintain most of their statistical power while keeping the danger of false positives at bay.
The work highlights that brain science is highly data-driven and statistical now. Although the visualizations — usually some orangey spots on an otherwise dark brain scan — seem simple, the data collection and interpretation that go into producing them is intense.
The point of the salmon study isn’t to prove that fMRI shouldn’t be used or is worthless. Brain scientists can do things with fMRI machines they otherwise couldn’t, said Ed Vul, an MIT neuroscience graduate.
