Summary
Young children do not assume ignorance implies error. Studies show that preschoolers do not predict characters will incorrectly infer outcomes based solely on a lack of knowledge.
Area of Science:
- Cognitive Development
- Theory of Mind
- Developmental Psychology
Background:
- Children's understanding of belief and knowledge is crucial for social interaction.
- Previous research suggests children may develop intuitive rules to interpret others' mental states.
Purpose of the Study:
- To investigate whether 4- and 5-year-old children apply the rule 'ignorance means you get it wrong.'
- To determine if children infer false beliefs from ignorance.
Main Methods:
- Two experiments presented scenarios where characters lacked knowledge about object locations.
- Participants (children and adults) predicted the character's actions and beliefs.
Main Results:
- Most children predicted characters would act correctly despite ignorance, unlike adults.
- Children's predictions indicated they did not assume ignorance leads to false beliefs.
Conclusions:
- Preschoolers do not appear to follow the 'ignorance means you get it wrong' heuristic.
- Children's reasoning about ignorance and belief is more nuanced than previously assumed.

Observational Learning
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning because...
Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
Obedience
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...
The Nativist Approach
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
Social Foundations of Self II: The Generalized Other
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
Milgram's Obedience to Authority
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”
