Chaney Et Al

Question 1

What was the conclusion

Answer 1

That it increases adherence and effective delivery by fun haler which manages young asthmatic

Using functional incentive device of funhaler = may improve health (need more research)

Question 2

How does study link to the development area

Answer 2

Illustrate how children learn and parents help to aquire desired effects through positive and negative reinforcement

Question 3

How does the field experiment effect the validity

Answer 3

Contend and control extraneous variables
Which decreases validity as as might have stronger impact on inhaler

Question 4

What is the reliability of the study
(Evaluation)

Answer 4

Field - but standardised which aids reliability
Same questions, same instructions, same inhaler, questions aire

Eg deep exhalation = spin faster

• sample only 32 children
  Small not large enough to establish controlled effect

Question 5

What is a strength of using a repeated measured design in Chaney study?

Answer 5

One strength is that there are no participant variables
acting as extraneous variables (1) so adherence to a
particular inhaler cannot be attributed to the personality of the child or the support of the family

Question 6

Chaney used a repeated measure design in their funhaler study

Explain how the design was used
(2 marks)

Answer 6

Repeated measures was used as participants took part in both conditions of the experiment (1)

first of all being assessed on the outcomes of using a standard inhaler and then being assessed on the outcomes of using the Funhaler (1).
