6.2 Cognitive and Language Development

Babies and toddlers are like sponges, soaking up knowledge through their senses and actions. From birth to age 7, they progress through stages of cognitive development, learning to think symbolically and understand their world.

Language blossoms rapidly in early childhood, starting with coos and babbles and evolving into complex sentences. Social interactions, like scaffolding and joint attention, play a crucial role in cognitive and language growth, setting the stage for future learning.

1 of 3

• Sensorimotor stage (birth to 2 years)
  • Infants learn about the world through their senses and motor actions such as grasping, sucking, and looking
  • Object permanence develops gradually, allowing infants to understand that objects continue to exist even when not in view (peek-a-boo)
  • Progression from reflexive behaviors (rooting reflex) to intentional, goal-directed actions (reaching for a toy)
• Preoperational stage (2 to 7 years)
  • Development of symbolic thinking, enabling children to use words, images, and symbols to represent objects and events (pretend play)
  • Egocentrism, or the inability to consider others' perspectives, is common (difficulty sharing toys)
  • Animism involves attributing life and consciousness to inanimate objects (talking to stuffed animals)
  • Centration refers to focusing on one aspect of a situation while ignoring other relevant aspects (judging quantity based on height alone)
  • Lack of conservation, meaning children do not understand that quantity remains constant despite changes in appearance (pouring liquid from a short, wide glass to a tall, narrow one)

Language milestones in early childhood

• Prelinguistic stage (birth to 1 year)
  • Cooing emerges around 2-3 months, involving the production of vowel-like sounds ("ahh," "ooh")
  • Babbling appears around 6-7 months, characterized by repetitive consonant-vowel combinations ("bababa," "mamama")
• One-word stage (1 to 1.5 years)
  • First words typically emerge around 12 months, often consisting of simple, meaningful words ("mama," "ball")
  • Holophrastic speech involves using single words to convey complex meanings ("up" to indicate wanting to be picked up)
• Two-word stage (1.5 to 2 years)
  • Children begin combining two words to form simple sentences ("more milk," "daddy go")
  • Telegraphic speech omits function words and focuses on content words ("baby sleep" instead of "the baby is sleeping")
• Multi-word stage (2 to 3 years)
  • Children start forming longer, more complex sentences with proper grammar and word order
  • Overgeneralization of grammatical rules is common, such as applying regular past tense endings to irregular verbs ("runned" instead of "ran")

Factors Influencing Cognitive and Language Development

Social influences on cognitive growth

• Scaffolding involves adults providing support and guidance to help children learn new skills, gradually reducing assistance as the child becomes more competent (helping a child complete a puzzle)
• Joint attention refers to the shared focus between a child and an adult on an object or event, facilitating language learning by associating words with their referents (pointing to a bird and saying "bird")
• Responsive caregiving entails prompt, appropriate, and consistent responses to a child's needs and communication attempts, fostering secure attachment and promoting cognitive and language development
• A language-rich environment exposes children to diverse vocabulary and complex language structures, encouraging language acquisition and comprehension (reading books, engaging in conversations)

Strategies for early academic skills

• Literacy strategies
  1. Reading aloud to children regularly, using age-appropriate books and engaging them in the story
  2. Encouraging interactive reading by asking questions, making predictions, and discussing the story
  3. Providing access to a variety of books and creating a designated reading area
  4. Modeling writing and encouraging children to experiment with writing tools (crayons, pencils)
  5. Incorporating literacy activities into daily routines and play (writing a grocery list, creating signs for a pretend store)
• Numeracy strategies
  1. Using math language in everyday conversations (counting steps, comparing sizes of objects)
  2. Providing opportunities for sorting, classifying, and patterning objects (sorting buttons by color, creating AB patterns with blocks)
  3. Encouraging exploration of shapes, sizes, and spatial relationships (building with blocks, completing shape puzzles)
  4. Incorporating number games and songs into play (singing counting songs, playing board games)
  5. Modeling problem-solving strategies and encouraging children to find solutions (dividing a snack equally, figuring out how to balance a block tower)
