Explanation / Answer

7)

The top-down and the bottom-up are two general process of perception and sensation. In bottom-up we percieve or sense things as it comes to us whereas, in a top-down process we have a context for our sensations and perception.

In the given scenario, the perception is made on the basis of a context that is it is known that at every Sunday noon there is a football match on fox, and thus, is determined that there was a football match on Fire without turning on T.V is a Top-down process.

8)

Absolute Threshold is the ability of the senses to detect the lowest level of any stimulus, whereas, the just noticeable difference is the ability to detect the difference between the two levels of stimulation.

Hence, this is just noticeable difference.

9)

Cochlea is responsible for converting auditory stimulations into neural impulses, while the olfactory epithelium tissue present inside the nasal cavity is responsible for converting the odors into neural impulses.

10)

Sensation is a process in which our senses on stimulation from a physical source converts that physical stimulus into nerve impulses and send it to the brain for interpretation and thus we sense that physical stimulation.

Perception is a process our brain translates the sensation into meaningful information by storing into our memories as experience, or attaching a emotion to it. It is a process how we understand any sensation.
