hyperactivity in children and sugar influences

Two researchers had the same question: Why are some children more active than others in the classroom? Is the amount of sugar in the diet a contributing factor? 

 

·        To answer the question the first researcher, Dr. Madison, asked parents of first grade students to keep a diary of food intake for a week. The same children were then observed in the classroom and rated on activity level. Dr. Madison found a statistically significant correlation of .6 between sugar intake and activity level. 

·        The second researcher, Dr. Johnson, approached the question in a different way. She gathered first grade students from local schools and brought them to her laboratory. Dr. Johnson randomly assigned the children to one of two groups – one group was given a sugary snack and the second group was given a non-sugary snack. She then observed all children in a mock classroom setting and each child was rated on activity level. Dr. Johnson found no significant difference in activity level between the two groups.
