UGC NET Questions (Paper – 1)

Psychological noise refers to internal states such as worries, biases or emotions that interfere with message reception. A student who is anxious or troubled may physically hear the teacher but fail to process the information meaningfully because attention is captured by personal concerns.

Option A:
Option A, construction sounds, represent physical or environmental noise, not internal psychological distraction.

Option B:
Option B is correct because the barrier arises from the student’s internal preoccupation, which disrupts attention even though the external environment may be adequate.

Option C:
Option C, microphone failure, is a technical problem in the channel, affecting loudness but not an internal mental state.

Option D:
Option D, a dim projector bulb, is a visual or technical barrier, not psychological noise within the learner.

Statements A, B, D and E correctly describe different types of noise, whereas C is wrong. A is true because external sounds can interfere with hearing the message. B is true as internal worries distract attention from the message. D is true since fatigue or illness can limit a learner’s ability to focus, and E is true because several types of noise may occur simultaneously. C is false because semantic noise occurs when there is misunderstanding of terms, not when there is complete agreement. Thus, C only is the wrong statement.

Option A:
Option A groups A and C as wrong, but A accurately defines physical noise as external disturbances. Including A among wrong statements misrepresents the concept, so A and C only cannot be accepted.

Option B:
Option B ties C and D together, but D is a correct description of physiological noise. Treating D as wrong contradicts standard classification, making C and D only an invalid set of wrong statements.

Option C:
Option C correctly selects C only, identifying semantic noise as misinterpretation rather than full agreement. It keeps A, B, D and E as true statements about other types of noise and their co-occurrence, so C only is the correct answer.

Option D:
Option D links C and E as wrong, yet E is true in acknowledging that multiple forms of noise can act at once. Misclassifying E as wrong leads to an inconsistent combination, so C and E only cannot be accepted.

Statements A and B are correct, whereas C and D are wrong and therefore form the correct combination of wrong statements. A is true because physical noise includes sounds such as traffic or construction that interfere with hearing a message. B is true since internal factors like prejudice and bias may distort how messages are interpreted and thus act as psychological noise. C is false because noise can arise at any point in the communication process, including at the receiver’s side. D is false because rigid rules and hierarchy may obstruct free flow of information and thus create a kind of organisational noise.

Option A:
Option A is incorrect because it treats C only as the wrong statement and overlooks D. While C is indeed wrong, D also misrepresents the possibility that organisational structure can interfere with communication. Leaving D out means this option does not capture all the wrong statements.

Option B:
Option B is incorrect because it selects D only as wrong and ignores C. Although D is a false statement, C is equally incorrect in claiming that noise never originates from the receiver. Since the question asks for all wrong statements, an option that includes only D cannot be accepted.

Option C:
Option C is correct because it groups C and D, the two statements that misrepresent the nature and sources of noise. It recognises that both the sender and receiver, as well as organisational structures, can contribute to noise in communication. By excluding A and B, which are accurate descriptions of physical and psychological noise, this option exactly matches the set of wrong statements.

Option D:
Option D is incorrect because it includes A, C and D as wrong statements. A is actually a correct statement defining physical noise as external sound interference. Including A among wrong statements makes this combination overinclusive and inconsistent with communication theory.

Statements A, B, C and E are correct, while D and F are incorrect. Physical noise does include external sounds that disturb hearing, psychological noise covers inner states like anxiety or bias, and semantic noise is linked to confusing meanings of words. Technological failure in an online class acts like physical or technical noise because it blocks the signal. Noise can affect both senders and receivers, and its presence does not make communication completely impossible, it only makes it more difficult. Therefore the correct set of statements is A, B, C and E.

Option A:
Option A is wrong because it omits E, ignoring the fact that technological breakdown is also a form of noise that disrupts communication. Although A, B and C are true, leaving out E means the option does not include all the correct statements. By capturing only part of the true set, A, B and C only cannot be accepted as the correct answer.

Option B:
Option B is correct because it includes all four true statements and excludes D and F, which misrepresent how noise operates. It acknowledges physical, psychological and semantic noise as well as technical breakdowns, giving a comprehensive picture of noise in educational communication. Since it does not treat the false statements as correct, this option matches the required set exactly.

Option C:
Option C incorrectly adds F to the otherwise correct group of A, B, C and E. F exaggerates by claiming that communication is always impossible when noise exists, which is not true because teachers and students often compensate. Including F makes this combination broader than the actual set of correct statements and therefore invalid. For this reason A, B, C, E and F only cannot be the correct answer.

Option D:
Option D is wrong because it treats C, D, E and F as correct and leaves out A and B, two basic statements about physical and psychological noise. It also includes both D and F, which wrongly claim that only senders are affected and that communication becomes impossible. This mixture of omissions and errors makes the option inconsistent with communication theory.

Statements A, B, C and E are correct, whereas D is incorrect. A is true because reducing unnecessary sound and movement minimises physical noise. B is true since repeating or visually emphasising key points provides backup when part of the message is lost. C is true as questioning helps the teacher diagnose whether learners have missed something. E is true because using more than one channel creates alternative pathways for meaning. D is false because teachers can influence psychological noise by building interest, reducing anxiety and creating a supportive climate. Therefore, D only is the wrong statement.

Option A:
Option A treats both A and D as wrong, but A correctly describes a practical strategy for reducing physical noise. Including A among wrong statements contradicts common classroom management practice, so A and D only cannot be accepted.

Option B:
Option B labels C and D as wrong, yet C accurately points out that checking understanding reveals the effects of noise. Misclassifying C undermines the diagnostic role of questioning, making C and D only an invalid option.

Option C:
Option C correctly identifies D only as the incorrect statement. It acknowledges that psychological noise is not entirely beyond teacher influence and that the other statements present valid strategies for managing different types of noise. Thus, D only is the correct answer.

Option D:
Option D lists B, C and D as wrong, but both B and C describe sound strategies for dealing with noise. Including them with D in a set of supposed wrong statements results in a logically inconsistent combination, so B, C and D only cannot be accepted.
