Questions 30-34
Complete the summary using the list of words and phrases, A-J, below.
Write the correct letter, A-J, in boxes 30-34 on your answer sheet.
NB: You may use any letter more than once.
Glass and Singer (1972) showed that situations in which there is intense noise have less effect on performance than circumstances in which 30 ..................... noise occurs. Subjects were divided into groups to perform a task. Some heard loud bursts of noise, others soft. For some subjects, the noise was predictable, while for others its occurrence was random. All groups were exposed to 31 ..................... noise. The predictable noise group 32 ..................... the unpredictable noise group on this task.
In the second part of the experiment, the four groups were given a proofreading task to complete under conditions of no noise. They were required to check written material for errors. The group which had been exposed to unpredictable noise 33 ..................... the group which had been exposed to predictable noise. The group which had been exposed to loud predictable noise performed better than those who had heard soft, unpredictable bursts. The results suggest that 34 ..................... noise produces fatigue but that this manifests itself later.

Write the correct letter, A-E, in boxes 35-40 on your answer sheet.
NB: You may use any letter more than once.
- Subjects exposed to noise find it difficult at first to concentrate on problem-solving tasks.
- Long-term exposure to noise can produce changes in behaviour which can still be observed a year later.
- The problems associated with exposure to noise do not arise if the subject knows they can make it stop.
- Exposure to high-pitched noise results in more errors than exposure to low-pitched noise.
- Subjects find it difficult to perform three tasks at the same time when exposed to noise.
- Noise affects a subject's capacity to repeat numbers while carrying out another task.
List of Researchers:
