Individuals with a high internal locus of control believe that events in their life derive primarily from their own actions; for example, if a person with an internal locus of control does not perform as well as they wanted to on a test, they would blame it on lack of preparedness on their part. If they performed well on a test, they would attribute this to ability to study.[1]. In the test-performance example, if a person with a high external locus of control does poorly on a test, they might attribute this to the difficulty of the test questions. If they performed well on a test, they might think the teacher was lenient or that they were lucky.[1]
Those with a high internal locus of control exhibit better control of their behavior[citation needed], tend to be more politically involved[citation needed] and are more likely to attempt to influence others than are those with an external locus of control.[citation needed] They also assign greater likelihood to their efforts being successful, and more actively seek information concerning their situation.[citation needed]
Locus of control has generated much research in a variety of areas in psychology. The construct is applicable to fields such as educational psychology, health psychology or clinical psychology. There will probably continue to be debate about whether specific or more global measures of locus of control will prove to be more useful.
