Snap shot study
A Snap shot study is a study carried out over a very short period of time such as hours and days. In comparison a longitudinal study is carried out over a longer period of time such as weeks, months or years.
Snap shot studies are obviously quicker and cheaper to carry out than longitudinal approaches and rarely suffer from attrition. However they only provide us with a ‘snapshot’ of human Behaviour and experience and therefore are not so useful when investigating development.
