Here you are:

1.      c      Explanation The term just noticeable difference is synonymous with difference threshold          and refers to the detection of change.


2.      c      Explanation: Sensory adaptation is the process whereby receptors become less responsive       to an unchanging stimulus.

3.      d      Explanation: Receptor cells in the retina responsible for color vision are cones.

4.      b      Explanation: Volume is the most similar to brightness and is based on the intensity of
the stimulus.

5.      c      Explanation: Conduction deafness refers to hearing problems that originate in the          eardrum and middle ear.

6.      c      Explanation: The five primary tastes are bitter, salty, sour, sweet, and umami.

7.      a      Explanation: The reason is that we have one canal to sense motion in each of the three
planes.

8.      a      Explanation: The tendency to interpret an object as always being the same physical
dimensions, regardless of its distance from the viewer, is known as size constancy.

9.      c      Explanation: Texture gradient refers to the fact that texture appears to become less
detailed in the distance.  

10.     c      Explanation: An illusion is a perception that does not correspond to reality.  Objects look
distorted in some fashion or a dimension is misperceived.
