An experiment was run to test the effect on reading comprehension of distraction by a television programme, which was presented while reading took place. Respondents, classified in terms of extroversion or introversion, carried out two reading comprehension tests in silence and in the presence of a television drama programme. As predicted, extroverts and introverts both performed better in silence, but there was a significant interaction that showed that extroverts performed better than introverts in the presence of television distraction. The findings are discussed in relation to previous research on this subject.
