A psychologist studies road-crossing decisions. Participants sit in a quiet classroom, watch recorded street scenes on a screen and press a key when they think it would be safe to cross. They do not enter a road during the study.
State one way that taking part in this study is different from deciding when to cross a road in everyday life.
Give one reason why the difference you stated may reduce the ecological validity of the findings.
