At which age would an infant typically begin to demonstrate an understanding of object permanence by actively searching for hidden objects? is frontal dementia?
The correct answer and explanation is:
An infant typically begins to demonstrate an understanding of object permanence between the ages of 6 to 8 months. Object permanence is the cognitive ability to understand that objects continue to exist even when they are not visible. Initially, infants may not search for hidden objects, but as their brain develops, they start to realize that objects that disappear from view are still present. This developmental milestone is critical in the cognitive development of infants and reflects the increasing sophistication of their memory and attention.
At around 6 months, infants may begin to look for objects that are hidden in their line of sight, but by 8 to 12 months, they are able to search for objects that are hidden out of sight. This indicates that their understanding of object permanence is developing. This ability plays a role in early problem-solving and understanding of cause and effect, laying the groundwork for more complex cognitive skills in later life.
On the other hand, frontal dementia, also referred to as frontotemporal dementia (FTD), is a neurodegenerative condition that primarily affects the frontal and temporal lobes of the brain. These areas are responsible for decision-making, personality, behavior, and language. Individuals with frontal dementia may exhibit changes in personality, behavior, and emotional responses. They may also experience cognitive impairments such as poor judgment, difficulty planning, and challenges in understanding social cues.
Frontal dementia typically occurs in individuals between the ages of 45 and 65 and is different from Alzheimer’s disease in that it tends to affect personality and behavior earlier in the disease process. The cognitive changes associated with FTD are more pronounced in areas like executive function, rather than memory, which is more commonly affected in Alzheimer’s disease.
