However, psychological constructs can be challenging to measure and quantify. This video examines reliability in the context of content analysis. A recent study in the journal Pediatrics reported that 4-year-olds who watched a fast-paced cartoon had worse performance on cognitive tasks, such as following rules in a game, listening to direction from an adult, and delaying gratification, compared to other children who watched a slower paced cartoon.1 In addition to the pace of the cartoon, the content of the cartoon may also have deleterious effects on its young viewers. This video uses a simple two-group design, to exemplify the issue of reliability, in examining the question of whether the cartoon SpongeBob SquarePants has more inappropriate content than does the cartoon Caillou.
