Cognitive Development and Piaget's Theory

Shift discussed begins at page 175, initiating a new section on cognitive development.
Key question from previous material: At what point does a child have memories?
- Answer: Around four years of age.

The section will focus predominantly on Jean Piaget's theories in cognitive development.
Comparison to other theorists:
- Freud's Psychosexual Relationships: Emphasizes different interactions with caregivers (e.g., interaction with mother vs. father).
- Erikson's Socio-Emotional Development: Introduces the importance of the child's social support system, mentioning oxytocin.
- Kohlberg's Moral Reasoning: Focuses on when individuals, particularly teenagers, begin to understand moral complexity (shades of gray).
Importance of understanding the context of definitions of "good" and "bad".

Developmental psychology includes prominent figures:
- Freud
- Erikson
- Piaget
- Kohlberg
Piaget’s contribution focuses on the cognitive aspects of child development, moving away from purely psychosocial perspectives to include scientific methodologies.
Piaget’s theory comprises four stages of cognitive development:
1. Sensorimotor Stage
2. Preoperational Stage
3. Concrete Operational Stage
4. Formal Operational Stage

Characteristics:
- Involves interactions through sensory experiences and motor activities.
- Caregivers use tactile and auditory stimuli (toys designed for sensory stimulation).
- Example: A Jack in the Box toy demonstrates this interaction as children engage with the auditory and visual stimuli.

Characteristics:
- Characterized by "out of sight, out of mind" phenomenon.
- Example: Children enjoy peekaboo as a stress-relieving game where they experience temporary separation and emotional flooding when visibility is restored.
- Development of object permanence: Recognition that objects still exist even when out of sight.
Observations:
- If a child does not search for a toy when covered, they exhibit characteristics of preoperational development.

Characteristics:
- Children understand the concept of conservation: Quantity remains the same despite changes in shape or appearance.
- Example in practice:
- A child is presented with two containers of the same size filled with the same amount of liquid. When pouring the liquid from one container to a taller, thinner container, a 5-year-old might incorrectly assume the taller one contains more liquid due to height perception.
- A 10-year-old, however, recognizes both contain the same amount of liquid, demonstrating conservation skills.

Characteristics:
- Development of more complex thinking, inference, and logical reasoning.
- Example: Discussion with a child about throwing trash out the window illustrates complex thought, where children reflect on consequences and moral reasoning at a mature level.
- Associated with frontal lobe development, generally not complete until the mid-twenties.

Introduced through Lev Vygotsky's principles, scaffolding involves providing support that helps children achieve greater understanding and independence:
- Example scenario:
- Two children (one in eighth grade, one in fifth grade) use an alarm system at home. As they learn, the older sibling can assist in demonstrating effective use, showing the cognitive development facilitated by prior experience.

Attachment is defined as how infants develop trust relationships with caregivers.
- Key types of attachment:
- Secure Attachment: Child feels safe and explores freely yet returns to caregiver for reassurance.
- Avoidant Attachment: Child avoids connection and interaction with the caregiver due to inconsistency or unavailability.
- Anxious Attachment: Child displays emotions of anxiety during separation and exhibits ambivalence upon the caregiver's return.
Mary Ainsworth's study delineates these attachment styles by assessing behaviors in a controlled environment, focusing on children's reactions when a parent leaves or returns.

A serious concept in child development highlighting the negative effects of neglect:
- Defined as the state where a child may die from lack of emotional connection, often seen in orphanages where caregivers are not present to meet the child's emotional needs.
- Represents profound consequences of insecure attachment and caregiving deficits in early childhood development.

The next part of the discussion, to be revisited, will cover trauma, abuse, and poverty as significant influences on child development at page 186 of the text where the examination of developmental impacts continues.
