"Studies show that reading develops imagination, induction, reflection and critical thinking, as well as vocabulary," Greenfield said. "Reading for pleasure is the key to developing these skills. Students today have more visual literacy and less print literacy. Many students do not read for pleasure and have not for decades."

Another study Greenfield analyzed found that college students who watched "CNN Headline News" with just the news anchor on screen and without the "news crawl" across the bottom of the screen remembered significantly more facts from the televised broadcast than those who watched it with the distraction of the crawling text and with additional stock market and weather information on the screen.   These and other studies show that multi-tasking "prevents people from getting a deeper understanding of information," Greenfield said.

Visual intelligence has been rising globally for 50 years, Greenfield said. In 1942, people's visual performance, as measured by a visual intelligence test known as Raven's Progressive Matrices, went steadily down with age and declined substantially from age 25 to 65. By 1992, there was a much less significant age-related disparity in visual intelligence, Greenfield said.   "In a 1992 study, visual IQ stayed almost flat from age 25 to 65," she said.   Greenfield believes much of this change is related to our increased use of technology, as well as other factors, including increased levels of formal education, improved nutrition, smaller families and increased societal complexity.

Email, videos of cats falling over, frivolous list-based websites—there’s no-denying that the Internet has given us some pretty wonderful things. However, all this awesomeness comes at a cost, and that cost is the destruction of our minds, sanity, and social lives. That’s right: For all the good it’s done, the Internet has the potential to make us very miserable, very angry, or very dead.

10 Email Is Addictive (Just Like Gambling)

The trouble is, email follows something called the “variable interval reinforcement schedule,” which is the same process that drives gambling addiction. In both cases, you perform an action (check your email or put a coin in the machine) in the hopes of receiving a reward (an interesting email or a whole lotta money). But that reward only comes at unpredictable times—causing you to perform the first action more and more frequently. It’s one of the strongest habit-training methods known to man, and nearly everyone who owns a computer has been subjected to it for years. 

As teenagers’ scores on standardized reading tests have declined or stagnated, some argue that the hours spent prowling the Internet are the enemy of reading — diminishing literacy, wrecking attention spans and destroying a precious common culture that exists only through the reading of books.

At least since the invention of television, critics have warned that electronic media would destroy reading.

Some traditionalists warn that digital reading is the intellectual equivalent of empty calories. Often, they argue, writers on the Internet employ a cryptic argot that vexes teachers and parents. Zigzagging through a cornucopia of words, pictures, video and sounds, they say, distracts more than strengthens readers. And many youths spend most of their time on the Internet playing games or sending instant messages, activities that involve minimal reading at best.

This study attempts to establish whether changes in digital literacy, through a period of five years, are age-dependent or the result of experience with technology. The study is based on empirical findings from two independent studies of Eshet-Alkalai & Amichai-Hamburger (2004), which investigated digital literacy skills among different age groups, and of Eshet-Alkalai and Chajut (2009), which investigated changes over time in these digital literacy skills among the same participants five years later. In order to distinguish between the age-related and the experience-related factors, the present study reports on findings from control groups of a similar age and demographic background, which were tested with tasks similar to Eshet-Alkalai & Chajut (2009). Results show two major patterns of change over time: (1) closing the gap between younger and older participants in tasks that emphasize experience and technical control (photo-visual and branching tasks); (2) widening the gap between younger and older participants in tasks that emphasize creativity and critical thinking (reproduction and information tasks). Based on the results from the control groups, we suggest that experience with technology, and not age-dependent cognitive development, accounts for the observed life-long changes in digital literacy skills. Results, especially the sharp decrease in information skills, suggest that the ability to find information or use digital environments does not guarantee an educated or smart use of digital environments.

Since the first television screens lit up our living rooms scientists have been studying its affect on young children. Now scientists have compared mother-child communication while watching TV to reading books or playing with toys to reveal the impact on children's development. The results show that watching TV can lead to less interaction between parents and children, with a detrimental impact on literacy and language skills.

The team found that when reading a book with their children parents used a more active communication style, bringing the child into contact with words they may not hear in every day speech, thereby improving their vocabulary and grammatical knowledge. In contrast watching TV resulted in significantly fewer descriptions and positive responses than mothers playing with toys. "Reading books together increased the maternal communication beyond a level required for reading, while watching TV decreased maternal communication. This is significant when we consider the amount of time young children spend watching TV. In some cases children are left alone to watch TV, missing out on any parental communication at a critical stage in their development," concluded Nathanson.

are our schools meeting this demand? In short, no. Or at least, not well enough. As a country we have devoted many resources to early childhood education initiatives that teach children to read. But once students possess these basic skills, they must be taught to interpret the information they read, to think critically, to write clearly, and to communicate effectively. Unfortunately, middle and high school students are not meeting state and national standards for basic reading proficiency, let alone developing higher literacy skills. According to the National Assessment of Educational Progress, only 38% of twelfth graders read at or above the proficient level.

Promoting adolescent literacy cannot be limited to reading and writing. To be highly literate in our culture involves mastering many different types of literacy- digital, financial, health, media, etc. If a student graduates high school able to read and write, but is unable to use a computer, we would consider their functional literacy limited. Yes, this is an oversimplification, but it serves to illustrate this point: literacy is defined and influenced by cultural and societal standards. And in a consumerist society such as ours, our jobs dictate many of those standards. These jobs demand digital literacy.

Some social critics are of the opinion that the spread of the electronic media is destroying literacy. Standardized test scores of reading and writing ability have in fact gone down in recent years. Are the new media the main cause?

the number of hours spent watching television declines as the education levels of viewers rise, but education-related differences in the amount of television use are not large and they have been narrowing

Volti notes that Marshall McLuhan was of the opinion that television affected viewers by requiring they use all their senses, that viewing television was not like reading, which is linear. Television is less concerned with sequence than reading.

Frequent users of smartphones quickly get used to the “auto-complete” function of their devices—the way they need only type a few letters and the phone fills in the rest. Maybe too used to it, in fact. This handy function seems to make adolescent users faster, but less accurate, when responding to a battery of cognitive tests, according to research published in 2009 in the journal Bioelectromagnetics.

A study led by researchers at the University of Coventry in Britain surveyed a group of eight- to twelve-year-olds about their texting habits, then asked them to write a sample text in the lab. The scientists found that kids who sent three or more text messages a day had significantly lower scores on literacy tests than children who sent none

The ready availability of search engines is changing the way we use our memories, reported psychologist Betsy Sparrow of Columbia University in a study published in Science last year. When people expect to have future access to information, Sparrow wrote, “they have lower rates of recall of the information itself and enhanced recall instead for where to access it.” It’s good to know where to find the information you need—but decades of cognitive science research shows that skills like critical thinking and problem-solving can be developed only in the context of factual knowledge. In other words, you’ve got to have knowledge stored in your head, not just in your computer.
