Final answer:
Infants at around one year of age should begin to respond to the instruction 'no' and recognize their name. This aligns with cognitive milestones that include understanding simple commands and starting to say their first words.
Step-by-step explanation:
Infant Response to 'No' and Recognition of Name
Infants generally start to respond to the instruction 'no' and quickly turn to the sound of their name by around one year of age.
At this stage, infants are often able to understand simple commands and exhibit signs of recognizing their own name.
They are becoming more interactive with their environment and can follow some basic instructions, especially when accompanied by gestures.
By twelve months, infants usually show further cognitive development like responding to 'no', understanding simple commands, and showing recognition of their names, as they start to say their first words and indicate their needs through babbling and various gestures.
Cognitive milestones also reflect certain social behaviors, such as separation anxiety and the beginnings of independent behavior.
It's important for caregivers and educators to be attentive to these developmental milestones to support children appropriately as they grow and learn.
By one to two years old, toddlers make significant advancements in language and behavior, responding to verbal commands and expressing their own desires, sometimes through words like 'no', or actions, including temper tantrums as part of their growing independence.
