Tamara Is Careless at the Office One Day and Accidentally

Tamara is careless at the office one day and accidentally prescribes the wrong medicine for a twelve year-old patient. When her new associate catches the mistake, he assumes she does not know the difference in medications and that she must not be practicing very good medicine, and that she may not be very bright. This tendency to underestimate the role of situational factors when explaining Tamara's behaviour is the:

A) internal locus of control
B) indiscriminatory process
C) cognitive dissonance theory
D) fundamental attribution error
