The Effect of Television on our Lives


THE EFFECT OF TELEVISION ON OUR LIVES



by


Gary Ruskin


from


Scientific American


, February 6, 2002

.


Perhaps


the


most


ironic


aspect


of


the


struggle


for


survival


is


how


easily


during


reasonably


interesting


ones


just


as


well.‖



organisms


can


be


harmed


by


that


which


they


desire.


The


trout


it


caught


by


the


f


isherman'’ lure, the mouse by cheese. But


at least those creatures have the excuse that


bait


and


cheese


look


like


sustenance.


Humans seldom have that consolation. The


temptations that can disrupt their lives are


often


pure


indulgences.


No


one


has


to


drink alcohol, for example. Realizing when


a diversion has gotten out of control is one


of the great challenges of life.

.


Excessive


cravings


do


not


necessarily


involve


physical


substances.


Gambling can become compulsive; sex can


become


obsessive.


One


activity,


however,


stands


out


for


its


prominence


and


ubiquity


—the world’s most popular leisure


pastime,


television.


Most


people


admit


to


having


a


love- hate


relationship


with


it.


They


complain


about


the


―bob


tube‖


and


―couch potatoes,‖ then they settle into their


sofas and grab the remote control. Parents


commonly


fret


about


their


children’s


viewing


(if


not


their


own).


Even


researchers


who


study


TV


for


a


living


marvel


at


the


mediums


hold


on


them


personally.


Percy


Tannenbaum


of


the


University


of


California


at


Berkeley


has


written: ―Among life’s more embarrassing


moments


have


been


countless


occasions


when


I


am


engaged


in


conversation


in


a


room while a TV set is on, and I cannot for


the


life


of


me


stop


from


periodically


glancing


over


to


the


screen.


This


occurs


not only during dull conversations but

.


Scientists


have


been


studying


the


effects of television for decades, generally


focusing on whether watching violence on


TV correlates with being violent in real life.


Less


attention


has


been


paid


to


the


basic


allure of the small screen



the medium, as


opposed to the message.


4


.


The


term


―TV


addiction‖


is


imprecise and laden with value judgments,


but


it


captures


the


essence


of


a


very


real


phenomenon.


Psychologists


and


psychiatrists


formally


define


substance


dependence as a disorder characterized by


criteria


that


include


spending


a


great


deal


of time using the substance; using it more


often


than


one


intends;


thinking


about


reducing


use


or


making


repeated


unsuccessful


efforts


to


reduce


use;


giving


up important social, family or occupational


activities


to


use


it;


and


reporting


withdrawal


symptoms


when


one


stops


using it.


5


.


All


these


criteria


can


apply


to


people who watch a lot of television. That


does not mean that watching television, per


se,


is


problematic.


Television


can


teach


and amuse; it can reach aesthetic heights; it


can


provide


much


needed


distraction


and


escape.


The


difficulty


arises


when


people


strongly sense that they ought not to watch


as much as they do and yet find themselves


strangely


unable


to


reduce


their


viewing.


Some


knowledge


of


how


the


medium


exerts its pull may help heavy viewers gain


better control over their lives.

The Effect of Television on our Lives



A body at Rest Tends to Stay at Rest


6


.


The


amount


of


time


people


spend


watching


television


is


astonishing.


On


average,


individuals


in


the


industrialized


world


devote


three


hours


a


day


to


the


pursuit



fully


half


of


their


leisure


time,


and more than on any single activity save


work and sleep. At this rate, someone who


lives to 75 would spend nine years in front


of


the


tube.


To


some


commentators


this


devotion


means


simply


that


people


enjoy


TV


and


make


a


conscious


decision


to


watch it. But if that is the whole story, why


do


so


many


people


experience


misgivings


about


how


much


they


view?


In


Gallup


polls


in


1992


and


1999,


two


out


of


five


adult


respondents


and


seven


out


of


10


teenagers


said


they


spent


too


much


time


watching


TV.


Other


surveys


have


consistently shown that roughly 10 percent


of adults call themselves TV addicts.


7


.


To study people’


s reactions to TV,


researchers


have


undertaken


laboratory


experiments in which they have monitored


the


brain


waves


(using


an


electro-


encephalograph,


or


EEG),


skin


resistance


or heart rate of people watching television.


To


track


behavior


and


emotion


in


the


normal


course


of


life,


as


opposed


to


the


artificial


conditions


of


the


lab,


they


have


used


the


Experience


Sampling


Method


(ESM).


Participants


carried


a


beeper,


and


we signaled them six to eight times a day,


at


random,


over


the


period


of


a


week;


whenever they heard the beep, they


wrote


down what they were doing and how they


were


feeling


using


a


standardized


scorecard.


8


.


As


one


might


expect,


people


who


were


watching


TV


when


the


researchers


beeped


them


reported


feeling


relaxed


and


passive.


The


EEG


studies


similarly


show


less


mental


stimulation,


as


measured


by


alpha


brain-wave


production,


during


viewing `than during reading.


9


.


What is more surprising is that the


sense


of


relaxation


ends


when


the


set


is


turned off, but the feelings of passivity and


lowered


alertness


continue.


Survey



participants


commonly


reflect


that


television


has


somehow


absorbed


or


sucked


out


their


energy,


leaving


them


depleted.


They


say


they


have


more


difficulty concentrating after viewing than


before.


In


contrast,


they


rarely


indicate


such difficulty after reading. After playing


sports


or


engaging


in


hobbies,


people


report


improvements


in


mood.


After


watching


TV,


people’s


moods


are


about


the same or worse than before.


10


.


Within moments of sitting or lying


down


and


pushing


the


―power‖


button


,


viewers


report


feeling


more


relaxed.


Because


the


relaxation


occurs


quickly,


people


are


conditioned


to


associate


viewing


with


rest


and


lack


of


tension.


the


association is positively reinforced because


viewers


remain


relaxed


throughout


viewing, and it is negatively reinforced via


the


stress


and


dysphoric


rumination


that


occurs once the screen goes blank again.


11


.


Habit-forming


drugs


work


in


similar ways. A tranquilizer that leaves the


body rapidly is much more likely to cause


dependence


than


one


that


leaves


the


body


slowly, precisely because the user is more


aware


that


the


drug’s


effects


are


wearing


off.


Similarly,


viewers’


vague


learned


sense that they will feel less relaxed if they


stop


viewing


may


be


a


more


significant


factor


in


not


turning


the


set


off.


Viewing


begets more viewing.


12


.


Thus,


the


irony


of


TV:


people


watch a great deal longer than they plan to,


even


though


prolonged


viewing


is


less


rewarding.


In


the


ESM


studies


the


longer


people


sat


in


front


of


the


set,


the


less


satisfaction they said they derived from it.


When signaled, heavy viewers (those who


consistently watch more than four hours a


day) tended to report on their ESM sheets


that they enjoy TV less than light viewers


did (less than two hours a day). For some,


a twinge of unease or guilt


that they aren’t


doing something more productive may also


accompany


and


depreciate


the


enjoyment


of


prolonged


viewing.


Researchers


in


Japan,


the


U.K.


and


the


U.S.


have


found


that


this


guilt


occurs


much


more


among
