ABSTRACT

The present study examined the ability to encode information about absolute size and its relation to executive functioning (EF). In particular, we explored whether the ability to inhibit relational information is critical in encoding size information. For this purpose, 4-, 6-,and 8-year-olds were given an absolute size task (Duffy, Huttenlocher, & Levine, 2005a)and a Flanker task. Our results showed that the ability to encode absolute size improves significantly between 4 and 8 years of age. The most prevalent type of error was relative error, which was significantly reduced when they reached age 8. There was also a significant correlation in all age groups between performance on the two tasks. Furthermore,we found a significant relationship between the amount of relative error and performance in the third block of the Flanker task in 4-year-olds. These findings indicate that executive function is critical in encoding absolute size in early childhood.
