Monozygotic Twins' Colour-Number Association: A Case Study

  Presentation By Mandy French

Introduction

• Investigates the color-number associations of monozygotic twins age 12 at testing

• Origin of color-number association is known to be a colored number jigsaw puzzle

• At age 3 the association was first noted when a teacher asked the boys to report numbers, but they insisted on reporting color names

• The colors that were reported were synonymous with the colors shown on the “Early Learning Centre” number jigsaw puzzle that the boys regularly played with

• The brothers showed the same color to number pairings, but the association was not quit as strong for one of the brothers

• By age 12 the boys report what color a digit is as well as most letters

• Researcher was interested in determining if the boys show the Stroop-like interference effects that are commonly used and if they had enduring associations

Methods

• Name the color in which a digit is displayed

• Hypothesized that if the digit is colored according to the jigsaw puzzle, then the boys will be quicker when compared to incorrectly colored digits

Participants

• Monozygotic twin boys aged 12 years and 2 months

• Physically and intellectually similar

Materials

• The twins separately selected colors for each of the digits from 0-9

• Numbers were displayed in 200pt font about 6cm high on the screen

• The color selections the boys made were stored as congruent colors

• Incongruent versions were created by changing the colors of discordant pairs

• The swaps were all for adjacent numbers
