Piaget's Stage 1 of Cognitive Development01:14

Piaget's Stage 1 of Cognitive Development

2.5K
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Piaget's Theory of Cognitive Development from Childhood into Adulthood

3.5K
Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.

The Nativist Approach

605
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...

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Observational Learning

1.4K
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...

Piaget's Stage 2 of Cognitive Development

1.3K
The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...

Summary

Young infants learn by noticing when things don't go as expected. Expectancy violations guide infant learning and exploration, helping them understand their environment.

Area of Science:

  • Developmental Psychology
  • Cognitive Science
  • Infant Learning

Background:

  • Infants face a vast amount of environmental information.
  • A key challenge is determining what information is relevant for learning.
  • Prior expectations play a role in filtering and prioritizing learning.

Purpose of the Study:

  • To investigate how infants identify learning opportunities.
  • To examine the role of expectancy violations in infant learning.
  • To understand how infants respond to unexpected events.

Main Methods:

  • 110 eleven-month-old infants participated.
  • Infants observed events violating prior expectations about object behavior.
  • Control events, nearly identical but non-violating, were also shown.

Main Results:

  • Expectancy violations significantly enhanced infant learning.
  • Infants showed increased exploration of objects that violated expectations.
  • Observed violations promoted hypothesis-testing behaviors specific to the violation type.

Conclusions:

  • Expectancy violations serve as crucial learning opportunities for infants.
  • Unexpected events guide infants' attention and information-seeking.
  • This mechanism helps infants navigate and learn from their environment early in life.
