A contrast is defined as the sum of each group mean multiplied by a coefficient for each group (i.e., a signed number, c j). [10] In equation form, , where L is the weighted sum of group means, the c j coefficients represent the assigned weights of the means (these must sum to 0 for orthogonal contrasts), and j represents the group means.

The same accessible information can result in assimilation or contrast effects, depending on how it is categorized. When the accessible information to construct the representation of the target is used, an assimilation effect results, whereas accessible information used to construct the standard of comparison leads to contrast effects.
Social comparison can be traced back to the pivotal paper by Herbert Hyman, back in 1942. Hyman revealed the assessment of one's own status is dependent on the group with whom one compares oneself.
