Analysis and A02 of the Cognitive Interview.

Interviewers should tailor their language to suit witness' ie- children. 

Judgemental comments should be avoided

Should review eye witness' descriptions

Overall cognitive interview improves recall, as seen in the study by Geiselman et al. However it does have its weakness'.

Less effective in young children

How soon the person is interviewed

Does not improve person identifcation in line ups.
