Final answer:
According to research, a large number of children in the care of a single adult may cause the caregiver to behave more restrictively and harshly, rather than fostering increased cooperation among children or improving communication skills in children. The caregiver may experience increased stress due to the demands and challenges of managing multiple children.
Step-by-step explanation:
According to research, an adult-child ratio with a large number of children in the care of a single adult may cause the caregiver to behave more restrictive and harsh. This can be attributed to the increased demands and stress on the caregiver when there are more children to supervise and manage. It becomes challenging for the caregiver to provide individual attention and ensure the safety and well-being of each child.
Increased cooperation among children is not a likely outcome in such a scenario, as the caregiver may be overwhelmed and less able to facilitate collaborative interactions among the children. Improved communication skills in children would also be unlikely, as the caregiver's restricted behavior may limit opportunities for positive communication and social interaction.
Moreover, the increased number of children in the care of a single adult can lead to greater stress for the caregiver. The presence of multiple children with diverse needs and behaviors can create a challenging and demanding environment, increasing the caregiver's stress levels.
