However, Luchins did find that if a space of time was involved between the primary information and the recent information then the recency effect could over ride the primacy effect. He said that the recency effect was important but not as important as the primacy effect (Silka 1989). Central traits are also said to affect attitude formation. Kelley (1950) found that central traits are more important to us when building first impressions during the substitute teacher study. Kelley found that using words such as 'warm ' or 'cold ' to describe someone can affect the way that people behave towards the described person.

This is believing that people have other traits such as being 'friendly ' because they are considered a 'warm ' person. It is thought that we judge people who have even just one good central trait on being a good person despite their peripheral traits. This is the same for having a bad central trait.

Even just reading about Jane Elliot 's experiments changes peoples attitudes and it is thought that they have contributed to a decrease in prejudice and discrimination. (Marsh
