When was the last time that you dialed a phone number from memory? It probably depends on how long you’ve been using     1     like a cellphone. While some generations can recall the days of memorizing phone numbers, it’s possible that members of Generation Z have never had to remember a single     2    . Why is this? Because smartphones offer quick and convenient ways for storing and     3     information. There is no need to memorize anything. But this isn’t without consequence. As digital devices develop, more and more users’ heavy reliance on them may be having disabling effects.“Digital dementia（失智）”is the term being used by medical professionals to identify some of these effects.

Some professionals like Jim Kwik, an expert in memory improvement and optimal brain performance, are taking a closer look at this effect. Kwik describes digital dementia like this:“...we’re     4     our brains to our smart devices. We’re so reliant on our smartphones that our smartphones are making us stupid. As medical studies chart the decline in memory and cognitive skills among smartphone users, a connection is made between symptoms     5     with dementia.”

The seriousness of overuse becomes     6     when you consider just how young smartphone users are becoming. Author and speaker Simon Sinek points out that young minds“Are not ready for it! Their minds cannot cope with the dopamine（多巴胺）.”Consequently, the overstimulation of screens and sounds lead to     7     more often than not. So now parents, teachers and managers are asking how to handle the influx（汇集）of young people with this kind of addiction.

First, monitor your cellphone use. Keep downloading applications like Forest or Checky. Then cut back on any     8     usage. Set a specific goal of how much you think you should use your phone.

Determine     9     areas for cellphone use. For example, while you’re at home, only allow yourself to check your phone somewhere like a home office. This way, the time in between tasks isn’t     10     filled with staring at your screen.
