Final answer:
The frontal lobe, specifically the prefrontal cortex, of the brain is responsible for planning and judgment. It carries out several executive functions, including decision-making and problem-solving. The frontal lobe is also critical for motor functions, language production, and personality expression.
Step-by-step explanation:
The section of the brain responsible for making plans and judgment is the frontal lobe. The frontal lobe, particularly the prefrontal cortex, is involved in higher-level cognitive functioning, including reasoning, planning, judgment, personality, and decision-making. This area of the brain helps individuals respond to complex problems, manage attention, initiate and regulate behavior, and make decisions.
Furthermore, the frontal lobe contains the motor cortex, key for planning and coordinating movement. It also contributes to language production through Broca's area and plays a crucial role in emotional expression. Assessing executive functions such as problem-solving ability and interpretation of common proverbs are ways to evaluate the function of the frontal lobe.
