Dr。 Sheedy says the added effort to change focus and the effort to change the angle of the lines of sight between the two eyes will likely make your eyes feel tired and your body spent.

52、 100 participants （參與者） a series of general-knowledge questions， such as naming the capital of France. For half of the study， participants had access to the Internet。 They had to look up the answer when they responded that they did not know the answer。 In the other half of the study, participants di

Furthermore， in some cases, the people with access to the Internet reported feeling as though they knew less compared

54、to the people without access。“With the popularity of the Internet， we are almost frequently connected to large amounts of information。 And when that data is within reach, people seem less likely to rely on their own knowledge，” said Professor Risko。Studying the results， the researchers thought that

55、access to the Internet might make it less acceptable to say you know something but are incorrect。 It is also possible that participants were more likely to say they didnt know an answer when they had access to the web because online searching offers an opportunity to confirm their answer， and the pr
