positive effects of this instruction with young children if it is accompanied by
frequent prompts. Under the CP instruction, children were more likely to
report correct than incorrect or confabulated details (cf. Akehurst
et al .,
2003 ).
Notably, Holliday & Albon ’ s (2004) research showed that the RE and CRI
instructions, when used together, reduced four - and fi ve - year - old children ’ s
reporting of misleading suggestions both during an interview and on subse-
quent memory tests. Moreover, children who were given MCI, ERMCI,
RE + CO and RE + CRI interviews, but not FCIs, recalled more correct
information about the fi lm, and their reports were more complete than chil-
dren given a control interview (see also Milne & Bull, 2002 ). In other words,
developmentally appropriate CIs enhanced reporting of correct information
and ameliorated the adverse effects of misinformation to some degree with
very young children. The fi nding that a shortened CI is effective with young
children is important given the problems surrounding interviewing these wit-
nesses (limited attention span, rapid forgetting) and the pressures on police
and practitioners to obtain correct information as soon as possible after a crime.
The implication of this research is that a developmentally appropriate interview
comprising these two CI instructions would take approximately 70% of the
time of a full CI.
Is a s horter CI viable with e lderly w itnesses?
Holliday and Humphries and their colleagues (Milne, Bull, Memon) are con-
ducting research in which individual CI instructions are being evaluated with
young - old (60 – 74 years) and old - old (75 – 100 years) witnesses in the context
of a participant - experienced staged event. The research will determine whether
or not a different set of instructions is benefi cial for young - old and old - old
adults. There is good reason to expect that older witnesses are, like other
special populations, capable of recollecting details that are forensically relevant
if they are interviewed using an interview protocol that is specifi cally designed
for them.
The Cognitive Interview

The n ext s tep: CI s of s uspects
More than 20 years have passed since the original CI was developed by
Geiselman et al. (1984) and over 15 years ago Professor Ray Bull wrote to
the UK government proposing research on this, but to no avail (personal
communication, 10 April 2008). It is therefore now time to determine its
effectiveness with crime suspects. In a recent article, Fisher & Perez (2007)
noted that the dearth of studies with these individuals may be due to ethical
restrictions and to the nature of the individuals themselves – they are suspects
in a criminal investigation. How likely are they to want to be interviewed for
a research study when they have been accused of a crime? Fisher
&
Perez proposed that suspects who are innocent, suspects who feel ashamed
of their crime and suspects who agree to provide information in the hope of
a lighter sentence might participate. Hence, they argue that the next step in
CI research should concentrate on testing whether or not a CI is viable with
cooperative suspects who are motivated to tell the truth. A second avenue
of fruitful research to consider is in contexts other than a criminal investiga-
tion. As Fisher & Perez point out, there are many areas in which diffi culties
exist in gathering information
– accident investigations of air, rail, car or
the workplace, war crimes and business decisions, to name but a few. This
exciting new area of CI research will challenge researchers for another 20 years
at least.
