Fiona got an e-mail from her manager, Rebecca, asking her to meet to discuss a past project. Unfortunately, Fiona was struggling to complete a project due that afternoon and had to reply that she was too busy to meet today. Rebecca was not pleased with Fiona's refusal to meet her and told another coworker that she thought Fiona was "too busy and important" to meet with her supervisor; thus, she is an unpleasant snob. Rebecca is making a(n) attribution of Fiona.

Dispositional attribution

Explanation:

Dispositional attribution also called internal attribution is the tendency of inferring that a particular event or behaviour is caused by internal characteristic rather than outside situations. Internal characteristics and psychological traits such as genetic traits, moods, attitudes, decisions and judgments, abilities, or effort are linked to the cause of an individual's behaviour or response.

Rebecca's disposition about Fiona was based on her perception of Fiona's internal psychological traits of feeling too busy and important.
