▶ Your Answer : The
lecturer argues that brain scan polygraphs are not more effective at detecting
lies. This contradicts the reading’s claims that brain scan is effective to
figure out lying.
Firstly,
the lecturer reputes the true not to be misidentified as lies. When someone
tell truth, the polygraghs can detect the truth as lies. This is because brains
are activated same part as someone is embrassed or lying. So scan can’t distinguish
between lie and truth.
Secondly,
the lecturer mentions that interpretation in object is totally false way. Since there
is no standard criteria for analyzing the responses in mistake. Thus,
polygraph is not a perfect way to analyze brain and even it’s false.
Lastly, the
lecturer contradicts difficulty of tricking by giving a example. The example is
this. If someone have to solve complicated math equations, then the anxious
part of brain will be activated. And there is another example. When someone is
telling untrustful story to another. But he or she can pretend to be honest as
well.
To sum up,
the lecturer argue that reading passage’s thesis. Therefore, the brain scan is
not a better method than conventional methods. |
