Previous research on the weapon focus effect indicates that schematic knowledge plays a large role in adult witnesses' ability to recall details of a crime. This study investigated whether the weapon focus effect would be found in young children (4- and 5- year-olds), whose schemas are less developed than those of adults. An experiment was conducted in which adults and children viewed a videotape depicting a male target stealing money from a woman's purse. In the four conditions, the target's apparent occupation and the objects that he held were manipulated, so that only one condition depicted a schema inconsistency between his occupation and the object. After watching the videotape, the participants were interviewed for details regarding the target's physical appearance and the object. As predicted, the schema inconsistency resulted in decreased recall accuracy for both children and adults. These results suggest that the weapon focus effect can be generalized to young children and that their eyewitness accounts are similar to those of adults. Additionally, adults recalled a significantly greater number of details than did the children, which was also predicted. It was interesting and unexpected to find that overall. adults recalled significantly more accurate descriptions than the children. This finding was contradictory to the results of some previous studies on eyewitness memory. / Department of Psychological Science

The effect of a weapon on memory accuracy for children and adults was examined. One-hundred eighty-six participants (87 7- and 8-year-old children and 99 college undergraduates) viewed one of four videotaped scenes in which a target individual committed a crime while carrying either a weapon that was consistent or inconsistent with his schema role or a neutral non-weapon that was consistent with his role. Participants were individually interviewed about the target's physical appearance. The results indicated that participants of both age groups were less accurate when the target individual carried a weapon that was inconsistent rather than consistent with his schema role. The results also indicated that adults were more accurate overall than children. These findings are consistent with previous findings on weapon focus effect and add to our knowledge of the development of memory. / Department of Psychological Science
