Which of the following is typical in a fight-or-flight response?

In a fight-or-flight response, respiration actually speeds up to increase oxygen intake, which is crucial for rapid energy production. This heightened respiratory rate supports the body's immediate need for oxygen during stressful situations, contrary to the concept of slowed respiration.

The heart rate increases during a fight-or-flight response to pump more blood to vital organs and muscles, enhancing physical performance. A slowed heart rate would contradict the body's need for heightened alertness and readiness to respond to danger.

Pupils typically dilate during a fight-or-flight response, allowing more light to enter the eyes and improving vision in low-light situations. Constricted pupils would limit visual acuity, which is counterproductive in a scenario requiring quick reactions to threats.

Perspiration often increases during a fight-or-flight response to help cool the body and manage heat generated by heightened physical activity. Inhibited perspiration would hinder effective thermoregulation and could negatively impact performance during stressful events.
