Cohesion

Cohesion

Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

Attachment

Attachment

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 physical...

The Nativist Approach

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...

Piaget's Stage 1 of Cognitive Development

Piaget's Stage 1 of Cognitive Development

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.

Relationship with Parents: Attachment

Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Imprinting

Imprinting

Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Cognitive Science
Developmental Psychology
Visual Perception

Background:

Object persistence is crucial for visual perception, with cohesion (a single bounded contour) being a key principle.
Research in adult cognition suggests cohesion is vital for object representation.

Purpose of the Study:

To investigate if minimal cohesion violations impair infants' ability to represent object quantities.
To test the power of cohesion as a constraint in early development.

Main Methods:

A forced-choice crawling paradigm was used with 10- and 12-month-old infants.
Infants observed crackers being placed into containers, with one cracker visibly splitting into two.
Infants' crawling behavior towards containers with different quantities was recorded.

Main Results:

Infants typically crawled towards containers with more crackers.
When a cracker split, infants failed to represent relative quantities.
This occurred despite controls for overall quantity and motion.

Conclusions:

Even minimal cohesion violations significantly impair infants' object representations.
Cohesion is a fundamental and sensitive principle of object persistence in early development.
Cohesion violations influence infants' overt behaviors and quantity representations.
