"The apple doesn't fall far from the tree." When it comes to device addiction，this may very well be the case.If you believe that how you engage with your smartphone has no impact on your children，think again.
   One study looked at 200 families and noted that the children of parents with phone addictions were much more likely to have behavior issues.In short，this obsession led to "technoference" or interruption of everyday interactions between parents and kids.In some cases，this interruption happened in face-to-face conversations，and in other cases，the devices disrupted playtime or meals.When this type of "technoference" occurred，parents rated their children as displaying more behavior problems，including whining，losing temper，sulking （生悶氣），and becoming frustrated.
   In addition，according to children development experts，there are bilateral （雙邊的） signaling systems that occur between adults and children，aiding the construction of the basic architecture of the brain.For example，infants and toddlers are highly engaged with the vocal cues of their parents that tend to happen with simplified grammar，a high-pitched tone，and exaggerated enthusiasm.This mode of relational conversation is incredibly important to a child's development.
   With the arrival of smartphones，many parents are distracted and stuck in what experts are calling "continuous partial attention" mode.This leads to significant and recurring disruptions to the parent-child conversation flow，which can impair not only a child's language learning ability but also their school achievements overall.
   While your habit may seem harmless，your kids may actually be imitating your behavior and forming a dependence of their own.One study reported that some teenagers may spend up to 12 hours — half of an entire day — online and mindlessly swiping through social media apps without engaging in any one piece of content beyond a few seconds.
   As a parent，the best thing you can do is lead by example.Try to limit time spent with technology，especially when it diverts （牽制） your attention from other priorities.Shut down smartphones at dinner.Set aside phone-free time each day to engage with your children without the distraction that technology brings.While you may not be able to completely cut ties with new modes of communication，you can be sure that your children get the one-on-one time they need to develop into healthy，happy adults.
