Boredom is a complex mental phenomenon, incorporating both affective and cognitive components, which cannot be understood within the confines of conflict theory alone. The paucity of fantasy in the bored person may reflect a developmental ego defect as well as, or instead of, the commonlycited impulse-defense conflicts. The need for externally-supplied stimulation characteristic of persons with a field-dependent cognitive style, and/or characterological passivity may be among the significant predisposing factors for the development of boredom, and phase-specific factors may encourage its occurrence at particular periods of life. Boredom in the analyst, too, is multiply determined; the analytic situation itself contains features that contribute to it.
