Physiological measures

• What is a strength of using physiological measures to assess stress?

  It avoids some problems associated with self-report measures
• What is one issue associated with self-report measures of stress?

  Social desirability bias
• Why are physiological measures like galvanic skin response important for certain groups of participants?

  They are the only way to measure stress in young children or non-human animals
• How do physiological measures compare to self-report measures in terms of objectivity?

  Physiological measures are more useful and objective
• What point did Lazarus make regarding stress measurement?

  Stress is not just a physiological response; perception is part of the experience
• What limitation do physiological measurements have according to Lazarus?

  They only tell us part of the story regarding stress
• What is a weakness of using physiological measures to measure stress?

  It only measures sympathetic arousal, which can occur due to any emotion.
• Which emotions can lead to increased sweat and skin conductance?

  Fear, anger, surprise, or sexual arousal.
• What did Osumi find regarding skin conductance and cognitive perception?

  There are changes in skin conductance based on feelings of fairness or unfairness.
• Why might skin conductance not be an accurate measure of stress?

  Because other emotional factors can influence the physiological response.
• What does it mean when physiological measures lack internal validity?

  It means they may not accurately measure what they intend to measure.
