Accepted Answer

absolute threshold.

Question 16

Roger feels something land on his hand but has yet to determine its nature.At this point in time,Roger has experienced which process(es)?

Accepted Answer

Sensation

Question 17

__________ is a specialized cell responsible for converting external stimuli into neural activity for a specific sensory system.

Accepted Answer

Sense receptor

Question 18

The ability to detect physical energy through our visual or touch systems is known as

Accepted Answer

Sensation refers to the process of detecting physical energy through our senses, such as vision or touch. Accommodation refers specifically to the process by which the lens of the eye adjusts to focus on objects at different distances, while perception is the process of interpreting sensory information in order to make sense of the world around us. Transduction is the process by which sensory information is converted into neural signals that can be processed by the brain.
