Breakdown of the Problem

To determine at what age infants can group objects with similar physical attributes, we need to analyze developmental milestones related to cognitive and perceptual skills in early infancy.

Relevant Concepts

Infants’ cognitive development involves the ability to categorize and perceive similarities and differences among objects. Research has shown that this capability emerges within specific age ranges.

Analysis and Detail

1. 1-3 months: At this stage, infants primarily engage in sensory exploration and are more focused on recognizing faces and basic shapes.

2. 4-6 months: During this period, infants begin to show interest in sorting and manipulating objects but are not yet grouping based on attributes.

3. 7-9 months: By this age, infants have developed more advanced cognitive skills and can categorize objects based on shape, color, and texture. This developmental stage is crucial for learning through play and exploration.

4. 3-4 months: Similar to the 1-3 months stage, infants at this age are not yet capable of grouping objects effectively.

Verify and Summarize

Based on the analysis, infants start to demonstrate the ability to group objects with similar attributes around the age of 7-9 months. Therefore, the correct answer is:

Final Answer

c. 7-9 months
