Study finds ultimate hack to protect teen brains from harmful screen time: Exercise (and good role-modeling)

by

Recent­ly, the Wall Street Jour­nal ran an arti­cle about how Insta­gram was affect­ing teen men­tal health. In par­tic­u­lar, some inter­nal stud­ies at Face­book (which owns Insta­gram) appeared to con­firm that when teen girls used the site, they suf­fered poor­er body image and were at increased risk for depres­sion and eat­ing disorders.

But is social media use itself at fault for mak­ing teen men­tal health worse? While some stud­ies sug­gest it is, oth­ers paint a more nuanced pic­ture, find­ing it dif­fi­cult to pin­point prob­lems with screen time itself ver­sus oth­er fac­tors some­times asso­ci­at­ed with social media use that may reduce teen well-being—like cyber­bul­ly­ing or social iso­la­tion. Plus, cur­rent con­clu­sions are often based on data from a sin­gle point in time, which makes it hard to prove that extend­ed screen time actu­al­ly caus­es poor­er men­tal health.

Now, find­ings from an inter­na­tion­al study on teens (details below) add more to this debate and point toward poten­tial guide­lines for screen use. Focus­ing on over 577,000 ado­les­cents from 42 coun­tries across Europe and North Amer­i­ca, the study’s results sug­gest that we might not have to wor­ry about screen time in small­er dos­es, until it reach­es a cer­tain harm­ful lev­el, and that exer­cise can play a pro­tec­tive role no mat­ter how much time a teen spends on screens.

Debate: Will brain-computer interfaces replace smartphones and other “mediating” devices?

by

The Fifth Indus­tri­al Rev­o­lu­tion: where mind meets machine (The National):

The Fifth Indus­tri­al Rev­o­lu­tion will make that con­nec­tion clos­er and seam­less, and will feel unmedi­at­ed. The smart device onto which we tap and into which we speak will dis­ap­pear. Brain-com­put­er inter­faces will replace them…Can we con­nect our brains – and our minds – to machines? The short answer is yes, and we have done so for some time. The longer answer is more com­pli­cat­ed, but more interesting.

Four guidelines for smart use of smartphones

by

These days, you can’t go any­where with­out hear­ing about how tech­nol­o­gy is ruin­ing every­thing, includ­ing our hap­pi­ness. There is some truth to this, but it’s not the whole story.

Tech­nol­o­gy can be bad for us—for exam­ple, when social media gives us FOMO (fear of miss­ing out) or traps us in fil­ter bub­bles that pre­vent us from see­ing mul­ti­ple points of view on impor­tant issues. As a soci­ety, we are increas­ing­ly con­cerned that tech­nolo­gies like smart­phones and social media result in more social com­par­i­son, bul­ly­ing, and loneliness—all stum­bling blocks to hap­pi­ness. Tech­nol­o­gy seems to be bad for our hap­pi­ness when it inter­feres with the men­tal, social, emo­tion­al, and behav­ioral process­es that con­tribute to well-being.

But we often fail to real­ize (and dis­cuss) the ways that tech­nol­o­gy can also sup­port hap­pi­ness and well-being—for exam­ple [Read more…] about Four guide­lines for smart use of smartphones

Q&A: What does the Facebook acquisition of CTRL-Labs mean for Neurotechnology and Augmented & Virtual Reality?

While sit­ting at din­ner with an unsus­pect­ing friend, my phone blew up with odd­ly-late mes­sages from fel­low neu­rotech­nol­o­gy com­rades. CTRL-Labs announced their impend­ing acqui­si­tion by Face­book and inte­gra­tion into Face­book Real­i­ty Labs (respon­si­ble for Ocu­lus et al.), for enough mon­ey to buy my guilt-induc­ing­ly-expen­sive New York cof­fee for a mea­ger 550,000 years. Woah—so very many ques­tions.
