Aditi seldom has time for breakfast because she attends morning classes. So she feels the urge to eat since her stomach is grumbling and feels empty. This is an example of -

Human behavior is often explained through a hierarchy of internal states and processes: need, drive, and motivation. These concepts help in understanding why individuals act in certain ways to reduce discomfort or satisfy desires, especially when basic physiological conditions are involved.

Key Points

• Drive is best illustrated in Aditi’s case. Her grumbling stomach and feeling of emptiness represent an internal state of discomfort that pushes her to take action to eat.
• A drive is a psychological state of arousal resulting from a need (like hunger) that motivates behavior to reduce that tension.
• Here, the biological need is hunger, and the drive is the discomfort and urge to eat caused by that unmet need.

Hint

• Need refers to the physiological requirement itself (food), which leads to the development of a drive when unfulfilled.
• Motivation is a broader term that includes both the internal drive and the resulting behavior (seeking food), but it doesn't focus on the internal tension as clearly as "drive" does.
• Extrinsic motivation is related to performing an action for external rewards or pressure, which is not the case here since Aditi’s urge is driven by internal physical discomfort.

Hence, the correct answer is drive.
