Which cognitive construct is defined as the ability to maintain performance during extended or repetitive tasks and can be affected by right-hemisphere damage?

• A. Long-Term Memory
• B. Working Memory
• C. Divided Attention
• D. Sustained Attention

Answer: (D)

Sustained attention is the ability to maintain focus and consistent performance on a task over a long period, especially when the task is repetitive or monotonous. This vigilance helps you detect targets and respond reliably despite fatigue or boredom. Right-hemisphere damage is commonly associated with deficits in sustaining attention, leading to more lapses, slower responses, and missed targets during extended tasks. That makes sustained attention the best fit for the description. In contrast, long-term memory concerns storing information for later retrieval, working memory involves holding and manipulating information for short periods, and divided attention refers to monitoring multiple streams of information at once—none of these inherently capture the ability to stay engaged and steadily perform over lengthy, repetitive tasks.
