When making attributions about a worker’s performance, people can assign responsibility to either internal or external factors?

This is true. Behavior can be described as a mix of internal factors within a person, such as character traits, intelligence, ability and so on, and external factors which are related to the environment. A person can posses the ability, but if the task is too difficult or if he finds that the coworkers are not friendly, he may have difficulty completing it.
