Menges (1973) Review of 1,000 American Studies

Aim: Menges research was titled ‘Openness and honesty versus coercion and deception in psychological research’ and looked at the amount of deception of participants in psychological research.

Illustrative background for MethodIllustrative background for Method ?? "content

Method

  • A meta-analysis of approximately 1,000 studies published in American Psychological Association (APA) journals.
Illustrative background for ResultsIllustrative background for Results ?? "content

Results

  • Around 20% of the studies involved giving participants false or misleading information, so they had not given informed consent.
  • Less than 50% had been debriefed and in only a minority of the research were the participants volunteers; 40% were students participating for credits.
  • Menges estimated that only 3% of studies involved no deception.
Illustrative background for Conclusion Illustrative background for Conclusion  ?? "content

Conclusion

  • Menges argued that his research showed the necessity for new ethical guidelines, as current research did not reflect the aims of openness and honesty in psychology.

Evaluation

  • Has led to increased awareness of ethics in psychology.
  • Has led to the development of new ethical guidelines.
  • Study has temporal validity – it was carried out in 1973, so hopefully things have changed for the better.

Glass & Singer (1972): Behavioural Aftereffects

The researchers exposed participants to noise to make them stressed.

Adverse aftereffects

  • Although subjects were able to adapt to loud noise and other stressors in laboratory experiments, they clearly demonstrated adverse aftereffects.
  • This suggests that adaptation to noise has long term costs.
Illustrative background for MethodIllustrative background for Method ?? "content

Method

  • Laboratory experiment.
  • 5 conditions:
    • Predictable loud or soft noise (9 second blast every minute);
    • Unpredictable loud or soft noise;
    • A control with no noise.
  • Participants were asked to complete simple task and galvanic skin responses measured.
  • There was a follow-up proof reading task where the number of errors made recorded.
Illustrative background for ResultsIllustrative background for Results ?? "content

Results

  • Although the noise was disruptive at first, participants were able to perform at the same level as the control after 4 minutes and galvanic skin responses returned to control levels.
  • There are limits to adaptation. Participants in the loud noise conditions struggled more with complex tasks such as reading three dials at the same time (like an air traffic controller might do), than simple tasks.
Illustrative background for ConclusionIllustrative background for Conclusion ?? "content

Conclusion

  • Noise can affect stress levels and cognitive performance, especially on complex tasks.
  • Individuals do adapt to noise levels, but this may have long term costs.
  • Predictable noise has less of an effect than unpredictable noise.
  • A further variable is perceived control over noise levels. This research has implications for individuals living in noisy urban environments.
Illustrative background for Inspiration for researchIllustrative background for Inspiration for research ?? "content

Inspiration for research

  • Glass & Singer’s research was inspired by a report in Fortune magazine where a shift worker from the Bronx had shot a boy from his window because their noise was keeping him awake.
  • The noise was unpredictable and outside of his control, therefore causing him stress and disrupting his sleep patterns.
Illustrative background for Evaluation Illustrative background for Evaluation  ?? "content

Evaluation

  • Strengths:
    • This was a laboratory experiment, so it was controlled and reliable and can be replicated.
  • Limitations
    • Lacks ecological validity; individuals react differently in a laboratory to real life situations.
    • Ethics – were the participants protected from harm, mild stress was induced and the experiment had possible long-term aftereffects?
    • Individual differences; some people seem less affected by noise than others.
