Two experiments were conducted to examine the effects of pressure on lineup decisions across child and adult eyewitnesses. In both experiments, participants were exposed to a target via videotape and then presented with a 6-person, target-absent lineup. Pressure was manipulated via lineup instructions (neutral vs. biased instructions). With neutral lineup instructions, children had a higher false-positive rate than did adults. With biased lineup instructions, children's patterns of false-positive responding paralleled that of adults; that is, an increase in false positives occurred. These results suggest that social pressure may not be the only factor driving children's higher false-positive responding, compared to adults. Potential factors that may be affecting children's lineup decision processes are discussed.
