Kelley’s covariation model which describes how people use the information about consistency, distinctiveness and consensus while forming causal attribution of certain behavior or situation stands out as one of the most significant models of attribution, as well as Weiner’s attribution theory of achievement motivation whose purpose is to determine specific cognitive, emotional and behavioral consequences of attributional process. Over the time newer models of attribution were made. One of them is the theory of relational attributions, which proposes that there is not only internal and external locus of causality, but also a third locus: relational attributions. Relational attributions refere to the made by a focal individual that locate the cause of an event within the relationship he has with another person. In other words, they can't be based on the actions of just one person, but on the characteristics of a relationship which can be directed either on the task or the person. The use of all three models can be seen in a wide range of personal and formal interpersonal and intergroup relations. Attribution biases are an important area of attributions. They are the observers causal explanations that systematically deviate from either the normative standard that should represent the rational processing of information, or the explanations made by other observers. The aim of this paper is to familiarize the reader with the process of attribution, attribution biases, as well as the most significant models in the field of attribution, with the purpose of deeper and wider understanding of the use of that field of psychology in diferent life surroundings.
