  • Geer And Maisel
    • Aim:
      • To see if perceived control or actual control can reduce stress reactions to aversive stimuli (photos of crash victims).
    • Methodology:
      • Laboratory experiment where participants were shown photos of dead car crash victims.
      • Stress levels were measured by GSR and HR electrodes.
      • Independent measures design - randomly assigned to 1 of 3 conditions.
    • Participants:
      • 60 psychology undergraduates from New York University,
    • Procedure:
      • Each sat in a sound-shielded room, wired up to GSR and heart rate monitors. Baseline measurements taken.
      • Group 1 - Given control over time they saw photos for. Press a button to terminate photograph for max of 35 seconds. Were told tone would precede each photograph.
      • Group 2 - Saw photos for same time as group 1. Told 10 second tone would precede each photo. Had no control, but knew what would happen.
      • Group 3 - Told from time to time they would see photos and hear tones. Had no control or predictability.
    • Findings:
      • Data from heart monitors seen as invalid so data was discarded. Group 2 were most stressed by the tone as they knew what was coming, yet had no control.
      • Group 1 were less stressed by the photo than group 2 and 3 who had no control.
    • Conclusions:
      • Results suggest that having the control to terminate aversive stimuli reduces the stressful impact of those stimuli.
