One problem reported by contemporary employers is the difficulty younger people have in focusing fully on their work because of a desire to be connected to what their friends are up to on social media. It might seem excessive to call use of technology addictive, but research shows that when people engage with Facebook, the search for messages and information leads to an increase in dopamine levels. Dopamine is a pleasure chemical, a 'reward' that the bran gives you which it also experiences with food, sex, and exercise. While those 3 activities are innate biological drives, social media absolutely is not - digital media is designed to hook you in, and there are scientists who argue that the brain's neuroplasticity - ie its ability to alter itself - means that it is being shaped as a result of our interaction with digital technology. The sheer volume of online data is overwhelming - look at your Facebook page and you'll be presented with multiple stimuli, many times that you'd experience on television where at any one time a single communication is happening. Advertisers used to talk abot 'jolts per minute'. Now, they refer to 'jolts per second' with regard to the stimulation we receive.
