Fisher and Johnston (1996) Allocated Patients with Chronic Pain to Conditions

Fisher and Johnston (1996) allocated patients with chronic pain to conditions in which their perceptions of control over their pain were experimentally increased or decreased.

A) Patients in the increased control condition performed a lifting task for longer than those in the decreased control condition.
B) The manipulation had no effect on behaviour
C) Patients in the increased control condition performed a lifting task for the same time as those in the decreased control condition but reported less pain.
D) Patients in the increased control condition performed a lifting task for longer than those in the decreased control condition, despite reporting more pain.
