S. Garven et al., Allegations of wrongdoing: The effects of reinforcement on children's mundane and fantastic claims, J APPL PSYC, 85(1), 2000, pp. 38-49
S. Garven, J. M. Wood, R. S. Malpass, and J. S. Shaw (1998) found that: the
interviewing techniques used in the McMartin Preschool case can induce pre
school children to make false allegations of wrongdoing against a classroom
visitor. In this study, 2 specific components of the McMartin interviews,
reinforcement and cowitness information, were examined more closely in inte
rviews of 120 children, ages 5 to 7 years. Children who received reinforcem
ent made 35% false allegations against a classroom visitor, compared with 1
2% made by controls. When questioned about "fantastic" events (e.g., being
taken from school in a helicopter), children receiving reinforcement made 5
2%, false allegations, compared with 5% made by controls. In a second inter
view, children repeated the allegations even when reinforcement had been di
scontinued. The findings indicate that reinforcement can swiftly induce chi
ldren to make: persistent false allegations of wrongdoing.
