According to the text, injury to the frontal lobe can result in all of the following except:

• A. Memory loss
• B. Decreased attention span
• C. A difficulty following directions
• D. Tactless behavior

Answer: (A)

Frontal lobe injuries disrupt executive functions—planning, organizing, sustaining attention, and controlling behavior. They also affect social judgment and impulse control, which can lead to tactless or inappropriate behavior. Memory, especially forming new long-term memories, relies more on temporal lobe structures like the hippocampus. While frontal damage can impact working memory and the ability to hold or manipulate information briefly, it is not typically the source of outright memory loss. That’s why memory loss is the exception among the listed effects. The other options—decreased attention span, difficulty following directions, and tactless behavior—fit with frontal lobe dysfunction because they reflect impairments in attention, sequencing, and social conduct that arise from disrupted executive control.
