Sometimes we can detect the presence of very weak stimuli and sometimes we can not. This is due to the
A) special properties of the stimulus we are attempting to detect.
B) inherent variability in the activity of our nervous systems.
C) random defects in our receptor cells.
D) psychophysical properties of stimulus detection problems.
E) psychophysical properties of environmental conditions.

Quizplus · Accepted Answer

The inherent variability in the activity of our nervous systems accounts for why we can sometimes detect very weak stimuli and sometimes cannot. This variability affects our sensory processing and perception, leading to differences in our ability to detect stimuli under similar conditions.
