According to Jean Piaget, abstract reasoning emerges during which stage of development?

A. Walking: Walking depends mainly on motor cortex, brainstem pattern generators, cerebellum, and spinal circuits rather than prefrontal cortex.
B. Fine motor skills: Fine motor control relies on motor and premotor cortices and cerebellar coordination; prefrontal cortex helps plan but isn’t the primary motor executor.
C. Self-regulation: The prefrontal cortex is centrally involved in executive functions such as impulse control, planning, and self-regulation.
D. Recognizing faces: Face recognition relies primarily on temporal-lobe regions (e.g., fusiform gyrus), not the prefrontal cortex.
E. Long-term memory: Long-term declarative memory depends on medial temporal structures (hippocampus) and distributed networks, not primarily the prefrontal cortex.

A. He will qualify for special education services:An IQ of 60 is well below average (typically in the range associated with mild intellectual disability), and children with such low scores commonly qualify for special education supports (though eligibility also depends on adaptive functioning and school policy).
B. He is more intelligent than 60 percent of his classmates:An IQ of 60 is below average (100 is the mean), so he scores lower than the majority.
C. He is of average intelligence:Average intelligence is around an IQ of 100.
D. He is likely to have savant syndrome:Savant syndrome is rare and not implied by a low IQ score.
E. He is much older than other children who have taken the test:The IQ score reflects relative performance, not the child’s age relative to test-takers.
