1
thousands of people worldwide suffer from a condition called poor contrast sensitivity.
2
Contrast sensitivity is the crispness of our vision.
3
It enables us to see objects or colors that do not clearly stand out from their backgrounds.
4
While this condition can be treated, correction involves wearing glasses or contact lenses or having surgery.
5
However, recent research may have provided another solution.
6
David Sanderson reports.
7
People with poor contrast sensitivity have problems with night driving, including seeing pedestrians walking along poorly lit streets.
8
They need extra light to read because they tire easily,
9
and they may even stumble in the street when they fail to distinguish a step or curb of a similarly colored sidewalk.
10
Poor contrast sensitivity affects the elderly and those suffering from amblyopia, or lazy eye.
11
Recently, neuroscientists at the University of Rochester in New York used video games to carry out experiments on poor contrast sensitivity.
12
Professor Frank Alexander explains.
13
The images we see are processed by the brain into information about our environment.
14
Neuroscientists have been studying how certain video games can enhance your eyesight and consequently, brain function.
15
In this particular experiment,
16
researchers studied two groups of college students who both played video games for 50 hours during a nine -week course.
17
One group played action -packed shooter games such as Unreal Tournament and Call of Duty,
18
which require precise, visually -guided aiming at targets, while the other played less intense puzzle games like Sims.
19
The results indicated that gamers who play shooter games experienced a 43 to 58 % improvement in their contrast sensitivity,
20
while those who played non -action games showed none.
21
Fast action video games improved the student's spatial resolution or ability to see small objects,
22
even when closely packed together on a cluttered screen. In fact, the students who played action games were able to distinguish such
23
objects even in the chaotic visual scenes of a game because gaming sharpens vision.
24
It also assists the brain in processing situations that are visually complex,
25
allowing a player to keep track of multiple items simultaneously while processing information that is constantly being updated or changed.
26
Poor contrast sensitivity was once considered impossible to change naturally, that is, without wearing glasses or undergoing surgery.
27
This research confirms that it can be improved.
28
Consequently, the brain makes better use of the visual information it receives.
29
Interestingly, games that best improved contrast sensitivity were unpredictable and required aiming at various targets while distinguishing friend from enemy before shooting.
30
This demands consistent alertness and analysis of what's happening on screen.
31
But was the improvement temporary or permanent?
32
This was crucial to the research.
33
The subjects were tested two days after the gaming period, after six months, and then two years later.
34
The results confirmed the initial findings video games extend our visual system to its limits
35
and the brain adapts itself accordingly the effects remain even two years after the initial gaming period is over
36
these findings will be applied to contrast sensitivity in people suffering from amblyopia
37
thus helping to give them stereo vision so
38
that both eyes are working together and also to the elderly whose contrast sensitivity has deteriorated with age.
39
In addition, the research is relevant to jobs requiring the fast, accurate processing of visual stimuli such as piloting a plane,
40
scanning x -rays, and screening luggage at airports.
41
Scientists are also interested in how video games can improve learning,
42
so that one day developers can create games that intrinsically enhance memory, perception, and other mental capabilities.
43
Number 1.
44
What is poor contrast sensitivity?
45
Number 2.
46
What was the purpose of the research?
47
Number 3.
48
What was the main finding of the research study?
49
Number 4.
50
Which feature of the games did researchers identify as most significant?
51
Number 5.
52
How can this research be applied outside the medical field?
53
Contrast sensitivity is the crispness of our vision.
54
It enables us to see objects or colors that do not clearly stand out from their backgrounds.
55
And they may even stumble in the street when they fail to distinguish a step or curb of a similarly colored sidewalk.
56

57
The results indicated that gamers who play shooter games experienced a 43 % to 58 % improvement in their contrast sensitivity.
58

59
Interestingly, games that best improved contrast sensitivity were unpredictable and required aiming at various targets while distinguishing friend from enemy before shooting.
60
Poor contrast sensitivity affects the elderly and those suffering from amblyopia, or lazy eye.
61
These findings will be applied to contrast sensitivity in people suffering from amblyopia,
62
thus helping to give them stereo vision so that both eyes are working together.
63
Thank you.
64
Thank you.

Bu videoyla nasıl çalışılır

  1. Videonun tamamını konuşmadan bir kez dinleyin ve bilmediğiniz kelimeleri not edin.
  2. Normal hızda cümle cümle tekrar edin; ritminiz konuşmacıyla aynı olana kadar her cümleyi yineleyin.
  3. Kendinizi kaydedin ve orijinaliyle karşılaştırın; suffer, distinguish, consequently gibi kelimelere özellikle dikkat edin.

Gölgeleme Tekniği Nedir?

Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
