Toddlers draw broad negative inferences from wrongdoers' moral violations.

Area of Science:

• Developmental psychology
• Moral cognition
• Social cognition

Background:

• By 2 years of age, children demonstrate expectations regarding moral principles.
• Previous research indicates children's understanding of moral concepts develops early.

Purpose of the Study:

• To investigate whether toddlers draw negative inferences about a wrongdoer's future behavior after witnessing a moral violation.
• To examine how detecting a moral violation influences toddlers' expectations of subsequent actions, including fairness and generosity.

Main Methods:

• Four experiments were conducted with 152 25-month-old toddlers.
• Toddlers observed a wrongdoer harm a protagonist, and their expectations of the wrongdoer's subsequent behavior (fairness, generosity) were assessed.
• The study manipulated whether the initial harmful act was construed as a moral violation.

Main Results:

• When toddlers perceived the initial act as a moral violation, they expected the wrongdoer to act unfairly but not generously later.
• When the initial act was not seen as a moral violation, these expectations reversed: unexpected unfairness, but not unexpected generosity.
• Detecting a moral violation lowered toddlers' assessment of the wrongdoer's moral character.

Conclusions:

• Young children's detection of moral violations significantly impacts their evaluations of an individual's moral character.
• These evaluations shape sophisticated expectations about how individuals will behave in novel social contexts.
• Findings contribute to understanding the development of moral reasoning and social judgment in early childhood.
