    The present study examined the efficacy of the enhanced cognitive interview, compared to the structured interview, in improving the recall of an event by older witnesses. This was achieved by designing and implementing a practical experiment. The present study utilised an experimental and independent measures design, aimed at collecting quantitative data. Two independent variables were used: (i) the age of the participant (older adults/general population) and (ii) the interview used (enhanced cognitive interview/structured interview). The dependant variable was how well the participants were able to recall the information presented to them by the visual stimulus. Participants were divided into two groups, adults from the general population (19-54 years old) and older adults (60-90 years old). They were asked to watch a short film and were then randomly allocated to the two interviewing techniques. It was found that the enhanced cognitive interview significantly increased recall of both age groups without increasing the amount of incorrect or confabulated information. Also the individuals in the general population condition were found to remember significantly more than those in the older adults group. However, the accuracy of the information recalled by the older adults was no less than that recalled by the general population.
