Methodological Issues Chaney

Question 1

Data

Answer 1

Quantitative
Answers were yes or no questions
Doesn’t tell us the reasons why there was a difference in attitude and behaviour

Question 2

Ethics

Answer 2

Not told aim but all guidelines were met.

Question 3

Internal

Answer 3

How sure are we that the research was actually measuring how the devices influence behaviour
Self report - social desirability bias - pretended they used the funhaler when they didn’t to seem like better parents
EV’s weren’t controlled for as was a field experiment (how strict parents were, how tired parent was, how busy they were) this means we don’t know what else influenced the use but ecological validity was high

Question 4

Ecological validity

Answer 4

Natural behaviour as in their homes

Not everyday that parents fill in questionnaire

Question 5

Reliability

Answer 5

Many aspects were standardised, questionnaire, length of time using funhaler, funhaler was same for every child. So could be repeated.
Only on 32 children so not large enough to establish a consistent effect

Question 6

Sample

Answer 6

Can’t be generalised as just on young children - appropriate for target population as toys were for young children

Question 7

Ethnocentrism

Answer 7

All from Australia, so ethnocentric as the toys wouldn’t appeal to children from all cultures

Question 8

Research method

Answer 8

Field experiment

Repeated measures - ppt variables controlled, forgetting inhaler but DC’s occurred working out aim
