His seventh book,The Distracted Mind: Ancient Brains in a High-Tech World, co-authored with Adam Gazzaley, MD, Ph.D., looks at why we all get so easily distracted from both the neuroscience and psychology perspectives. The Distracted Mind (MIT Press) was published in October 2016.

I have been interested in the impact of technology on people since technology entered our world in the form of large, hidden mainframe computers. My first research project in this area was in 1985! Since then I have published dozens of research papers on a variety of topics including technology in the workplace, the coming impact of Y2K (yep, that long ago), video games, online dating, multitasking, MySpace, parenting, writing, and a bunch more topics. Currently, in the George Marsh Applied Cognition Laboratory at California State University, Dominguez Hills, we are running many research projects including:

  • Similarities and differences between light and heavy technology users in executive function performance and prefrontal cortex oxygenation.
  • An examination of the predictors of course performance based on executive function, anxiety and technology use (assessed by both self-report and a smartphone app).
  • An examination of the feelings of "presence" in 3D movies and their applicability to education.
  • The impact of classroom text message interruptions on comprehension.
  • The impact of media usage on physical and mental health.
  • Generational characteristics, values and beliefs among and between Baby Boomers, Generation X, Net Generation, iGeneration and Generation "C" (for constantly connected) children born in the new millennium.

We are continuing to examine the world of technology which seemingly changes daily. With the rapid advances coming into and penetrating our society we investigate how they impact people. Stay tuned for more from my lab!


I live in Solana Beach, California and enjoy a whole lot of things outside of my work world.  I have four children ranging from 25 to 40.  Thank goodness none of them still live at home although they visit often and connect through a whole lot of different technologies.  My family and I make an annual gingerbread house from scratch and if you hop on my website you can see photos (tucked way down on the left side of the page is a link). I dabble in art that involves canvases with old technology and old rock 'n roll music (link to pics also down at the bottom of the website).  I love theater and, in particular, musicals of any kind.  I love music of "nearly" any kind.  I go to a zillion movies a year (well, maybe only about 60 or so) and particularly like indie films.  Been to Sundance Film Festival many times and recently switched from cold Park City to warm Palm Springs for the Palm Springs International Film Festival where we typically see 6-9 movies in 3 days.  I love to cook (and eat) although my son (who cooked for 90 people at my 60th birthday party five years ago) is a much better cook.  I read voraciously, but only murder mysteries, international intrigue and science fiction.  I watch little television outside of The Daily Show, The Colbert Report, MSNBC (love Rachel) and the Big Bang Theory.  I do miss 24 but "Homeland" and "Covert Affairs" are quite good.  During the summer I body surf and there is no way I am ever going to get up on skis at the top of a hill. Cross country skiiing is ok but I am sure that I would break at least two bones on my first downhill attempt.  I love to travel and get lots of opportunities giving talks all over the world.   All in all, I can't think of a better life! I recently "half" retired meaning that I still do all my research but only teach one semester a year. In honor of my retirement I was "elevated" (?) to emeritus status although I swear that I can't be a day over 40 and it seems like I just started teaching even though I have been at Dominguez Hills for 41 years!

Rewired: The Psychology of Technology

I study the impact of technology and media on children, teens and adults in all arenas including the home, school, the workplace and leisure time activities. My newest book, iDisorder: Understanding Our Obsession With Technology and Overcoming its Hold on Us, discusses how technology is making us all exhibit signs and symptoms of psychiatric disorders such as OCD, narcissism, voyeurism, and depression. It is full of strategies for resetting your brain and avoiding an iDisorder. My next book is called "The Distracted Mind" and is due out in early 2016.
