What were the independent and dependent variables in the study described here? What are the levels of the IV?

**Understanding Sugar and Hyperactivity: A Comprehensive Analysis** **Instructions:** Using the following information and prompts from your textbook author’s blog, read through the information provided and then as a group, determine the best responses. Here's something "everybody says": Kids will become hyperactive if they eat too much sugar. This folk belief is as much a part of North American cultural wisdom as learning styles and the catharsis hypothesis. But this [column in the *New York Times*](#) explains that, like learning styles and catharsis, the idea of a "sugar high" is also a myth. The physician who wrote the column traced the modern idea of sugar causing hyperactivity to 1975. But then the author describes a randomized clinical trial on this question. Here's the description: *An **extraordinarily rigorous study settled the question in 1994**. Writing in the *New England Journal of Medicine*, a group of scientists tested normal preschoolers and children whose parents described them as being sensitive to sugar. Neither the parents, the children nor the research staff knew which of the children were getting sugary foods, and which were getting a diet sweetened with aspartame and other artificial sweeteners. Urine was tested to verify compliance with the diets. Nine different measures of cognitive and behavioral performance were assessed, with measurements taken at five-second intervals.* **The original study** was, indeed, ambitious. The authors provided all food to the homes of the children in the study so they could completely control what sweeteners were being used. The study took place over nine weeks in a repeated-measures design—the diets were based on sucrose (sugar) one week, aspartame another week, and saccharine during another week. The researchers measured the children's cognitive performance and mood throughout the study. *The study concluded that sugar does not affect children’s behavior or cognitive function. An [editorial that accompanied the study](#) put a fine point on that conclusion, stating “there is no evidence that sugar alone can turn a child with normal attention into a hyperactive child.”*
