Piaget's Stage 2 of Cognitive Development01:14

Piaget's Stage 2 of Cognitive Development

1.2K
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...

Piaget's Stage 1 of Cognitive Development

2.4K
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

3.2K
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 Approach01:21

The Nativist Approach

581
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...

Attachment01:20

Attachment

709
Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

Theory of Romantic Attachment in Adulthood

50.2K
Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Area of Science:

  • Paleoanthropology
  • Geology

Background:

  • The Taung hominin fossil, discovered in 1924, has been subject to various interpretations regarding its depositional environment.
  • Previous research proposed that the pink carbonate deposits containing fossils formed in open terrestrial environments.

Purpose of the Study:

  • To challenge the proposed model of open terrestrial pedogenic deposits for the Taung hominin fossil's formation.
  • To re-evaluate the depositional environments of the tufa formations at Buxton Limeworks.

Main Methods:

  • Field observations from paleontological excavations at Buxton Limeworks (1988-1993).
  • Laboratory analysis of recovered fossils and associated sediments.

Main Results:

  • The pink carbonate deposits at Taung are not a single, uniform "unit" as previously suggested.
  • Excavations revealed diverse fossiliferous deposits with distinct taphonomic origins and formation processes.
  • While some deposits align with the terrestrial model, the most significant fossils originate from different formations.

Conclusions:

  • The majority of fossiliferous deposits at Taung, including those yielding key hominin fossils, are best interpreted as karst-related formations.
  • This challenges the notion of open terrestrial pedogenic origins for the Taung hominin's depositional environment.
