The effectiveness of practice and stringent lineup instructions in improvin
g children's identifications from sequential-presentation lineups was inves
tigated. Elementary school children (N = 144) viewed a slide sequence of a
crime followed by practice or control procedures. In the practice condition
s, children either practiced themselves (self) or watched a videotape of a
child practicing (modeled). Practice consisted of 2 target-absent lineups (
unmixed) or a target-absent lineup and a target-present lineup (mixed) of f
emale photos unrelated to the crime. The control conditions did not engage
in identification practice, All witnesses were given stringent instructions
for identifying the criminal from target-present or target-absent sequenti
al-presentation lineups, Multiple responding was dramatically reduced. Prac
tice affected gender differentially. Female children increased in correct i
dentifications, whereas male children increased in false rejections. None o
f the practice procedures reduced foil identifications from target-absent l
ineups.
