Deficient cognitive control fuels children's exuberant false allegations

Area of Science:

• Developmental Psychology
• Eyewitness Testimony Research
• Cognitive Science

Background:

• A subset of children in eyewitness studies and real investigations produce numerous false allegations.
• Understanding the cognitive characteristics of these children is crucial for accurate testimony evaluation.
• Previous eyewitness studies have identified children who make false reports of events.

Purpose of the Study:

• To investigate the cognitive characteristics distinguishing children who produce frequent false eyewitness reports.
• To identify specific cognitive tasks that predict the number of false allegations made by children.
• To differentiate mechanisms underlying occasional memory intrusions versus persistent confabulation in children.

Main Methods:

• Reinterviewed 61 children (ages 4-9) who previously participated in an eyewitness study.
• Administered a battery of cognitive tasks, including utilization, response conflict (Luria tapping), and theory of mind tasks.
• Utilized factor analysis to identify common processes underlying task performance and their relation to false reports.

Main Results:

• Performance on utilization, response conflict, and theory of mind tasks predicted the number of false reports of touching.
• These tasks correctly classified 90.16% of children as typical or exuberant (≥3 false reports) reporters.
• A common underlying process accounted for 49% of the variability in children's false reports.

Conclusions:

• Deficient cognitive control, particularly in executive functions, is a key factor fueling exuberant false reports in young children.
• The cognitive mechanisms driving occasional memory intrusions differ from those driving persistent confabulation.
• Cognitive task performance offers a reliable method for identifying children at higher risk for generating numerous false allegations.
