What are three aspects of the orienting response?

The orienting response is a critical aspect of how organisms react to new or unexpected stimuli in their environment. It typically involves a variety of physiological and behavioral changes aimed at directing attention towards potential threats or novel experiences.

In the context of the correct choice, increased muscle tone indicates a readiness to respond to stimuli. Sensory sensitivity reflects heightened awareness and responsiveness to environmental cues, allowing for better detection of relevant stimuli. Decreased heart rate can occur as the body shifts from a state of rest to a more focused one, facilitating calmness while still being alert and ready to act.

Together, these three aspects illustrate the biological and psychological engagement when an individual encounters something new or requires additional attention, demonstrating the dynamic interplay between readiness, alertness, and physiological adaptation in response to stimuli. This aligns with the understanding of the orienting response as an automatic reaction that enhances situational awareness and preparedness for action.
