Assertion and Reason Based

Q1: Assertion: Psychophysics is a field that explores the connection between physical stimuli and subjective sensations.
Reason: It is a branch of physics that studies the behavior of subatomic particles.
(a) Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) The assertion is true, but the reason is false.
(d) The assertion is false, but the reason is true.

Q2: Assertion: Sustained attention pertains to the capacity to sustain focus on a particular stimulus over an extended period.
Reason: Selective attention involves attending to two different things at the same time.
(a) Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) The assertion is true, but the reason is false.
(d) The assertion is false, but the reason is true.

Q3: Assertion: The principle of proximity states that objects that are close together in space or time are perceived as a group.
Reason: The principle of closure suggests that we tend to perceive objects as complete wholes, even if there are gaps in the information.
(a) Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) The assertion is true, but the reason is false.
(d) The assertion is false, but the reason is true.

Q4: Assertion: Binocular cues for depth perception require the use of both eyes.
Reason: Monocular cues for depth perception rely on the slight difference between the images formed on each retina.
(a) Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) The assertion is true, but the reason is false.
(d) The assertion is false, but the reason is true.

Q5: Assertion: Perceptual constancy refers to the ability to perceive objects in a relatively stable manner.
Reason: Cognitive styles do not have a crucial effect on how we perceive our environment.
(a) Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) The assertion is true, but the reason is false.
(d) The assertion is false, but the reason is true.
