A strength of the theory is that it is supported by evidence. For example, Slay and Frey found that when children were presented with split screen images of males and females performing the same tasks, younger children spent roughly the same time looking at the males and the females, whereas those in the gender constancy stage spent more time looking at the model the same gender as them. This supports Kohlberg’s assumption that children will seek out same gender role models once they reach the gender constancy stage.
