murzikaleks [220]

Answer:

A. Sensation

Explanation:

  • <em>A sensation</em> is a mental process (like hearing, seeing or smelling) resulting from the immediate external stimulation of a sense organ often as distinguished from a conscious awareness of the sensory process, it's a physical feeling or perception resulting from something that happens to or come into contact with the body. Considering the example given the freshly cut grass, gentle breeze and sound of children laughing are the physical feelings stimulating your nose, skin, and ears.
  • <em>Selective attention</em> is focusing on a particular object in the environment for a certain period, in your example, the subject is not specifically focusing on one thing at the time.
  • <em>Sensory adaption</em> is the reduction in sensitivity to a stimulus after constant exposure to it, in this case, the subject is nos experiencing awareness of a constant stimulus.
  • <em>Cognition</em> is the process of acquiring knowledge and understanding through thought, experience, and the senses. In your example, the data obtained by the subject is still not processed.

I hope you find this information useful and interesting! Good luck!

the control group is a way for scientists to see how an experiment truly affected or altered the subject
