| The over55s who grew up watching blackandwhite programs and films are more likely to dream in grey, research suggests. And the under25s who have watched color TV all their lives tend to have colorful adventures in_the_ land_of_nod. Research from the first half of the 20th century,especially in the 1930s and 1950s,suggested that most dreams are in black and white. But results from tests in the 1960s and later suggested that up to 80 per cent of dreams contain some colors. Since this period marked the transition (过渡) from blackandwhite films and TV to widespread Technicolor (彩色印片法),an obvious explanation was that television was influencing dreams,but differences between the studies prevented the researchers from drawing any firm conclusions. Later studies asked subjects (实验对象) to complete dream diaries immediately they woke up,but the earlier research used questionnaires completed in the middle of the day,so the subjects might have simply forgotten color elements in their dreams and assumed they were grey. To solve the problem,psychologist Eva Murzyn asked 60 subjects,half of whom were under 25 and half over 55,to answer a questionnaire on the color of their dreams and their childhood exposure (暴露) to films and TV. The subjects then recorded different aspects of their dreams in a diary every morning. She found there was no significant difference between results drawn from the questionnaires and the dream diaries. She then analyzed data to find out whether an early exposure to blackandwhite TV or films could still have a lasting effect on her subjects'dreams,40 years later. Less than five per cent of the under25s'dreams were black and white.But the over55s who had access to blackandwhite media in their younger days reported dreaming in black and white roughly a quarter of the time. Murzyn said,"There could be a critical period in our childhood when watching films has a big influence on the way dreams are formed." People's attention might be heightened during the time they are watching TV or films. |
