Muselmann was a derogatory term used
among inmates of World War II Nazi
concentration camps to refer to those suffering
from a combination of starvation and
exhaustion and who were resigned to their
impending death. The Muselmann inmates
exhibited severe emaciation and physical
weakness, an apathetic listlessness regarding
their own fate, and unresponsiveness to their

personal control needed fewer pain relievers

Lack of control leads to learned helplessness
Dogs conditioned to receive a shock did not move to relieve
themselves from it even though they were free to.
A child who performs poorly on
math tests and assignments will
quickly begin to feel that nothing
he does will have any effect on his
math performance. When later
faced with any type of math-
related task, he may experience a
sense of helplessness.
To study the effects of enhanced personal
responsibility and choice in a group of nursing
• Does increased control have
general beneficial effects?
• How would physical, mental
alertness, activity, sociability
and satisfaction be affected?
• Would the sense of
responsibility be generalised to
other aspects of their lives?
• Study carried out on two
floors of a top Conneticut
• All residents had similar:
health, socioeconomic status
and length of stay in home.
• 1 floor = Responsibility
Induced Group (RIG). This was
the experimental condition.
• 2nd Floor = comparison group.
This was the control

Each group was briefed differently about
their stay in the nursing home:
1 week before the briefing Questionnaires 1 and

Asked participants about their level of
control in their lives and their
happiness and activeness
Nurses rated participants happiness,
alertness, dependency, sociability,
activity levels, types of activity.
Researcher also rated participants
They also noted whether residents went to the movie night or took part in
Questionnaire 1 (given 1 week before and 3 weeks after the briefing)
• Happiness and Activeness increased in the RIG although they didn’t
perceive themselves as having greater control .
• RIG were seen as being more alert
Questionnaire 2 – What the nurses thought…
• 93 % of the RIG group had improved and were more active (moving,
talking etc) than passive (reading).
• Movie attendance higher in the RIG
• Jelly bean guessing competition – 10 participants from the RIG, 1 from
Personal responsibility = increased well being
But what about the sample?
71% of CG became more debilitated over the 3 weeks
The improvements in the conditions of the RIG group were
quite small – what if you made bigger changes?
What made them go to the movies? Happiness or control?
Real world application – conditions in a care home?
Method – field experiment
Reliability – refers to whether something is consistent.
Consistency of answers on a questionnaire – test-retest
Validity – refers to whether something is legitimate or true.
Internal validity concerns the extent to which the researcher has
tested what they intended to test.
Ecological validity concerns the extent to which the research findings
can be generalised beyond the research setting.
Experimenter bias Extraneous variables
Sampling – representative?
Ethics – Informed consent? Deception? Lack of right to withdraw?
Privacy? Protect from harm? Confidentiality?
