A moral developmental perspective on children’s eyewitness identification: Does intent matter?

Abstract

In Study 1, eyewitness identification of the perpetrator of a “crime” (fire), framed as either intended or unintended, was studied in 138 children, ages 7 to 18. Analysis using Signal Detection reveals an interaction of age and condition on decisional bias. Like in past studies, the framing of the act had no effect on the 7- to 9-year-olds, but did have an effect on decisional bias for the other age groups. Decisional bias was more lax (indicting more false alarms) in the intended condition for 10- to 12- and 14- to 15-year-olds but was more stringent (fewer false alarms) for the 16- to 18-year-olds. This pattern of age and condition differs from the pattern of explicit judgments (how bad the act was, how much punishment it deserved, and how bad it is to commit a false alarm or a miss). Study 2 was conducted to confirm the unexpected findings for the 10- to 12-year-olds. Forty-two children, ages 10–12, viewed the same film, which was framed as unintended but resulting either in (a) major or (b) minor damage (fire). Approximately half randomly assigned to condition (a) and half to (b). Parallel results were obtained with an earlier study, with lower bias scores (more false alarms) in the major than minor damage conditions. Thus, from both studies, we may conclude that decisional bias is more lenient (resulting in more false alarms) for 10- to 12-year-olds when either intent or damage is bad.
