Question 6 Multiple Choice (Single Answer)

In classical conditioning, the unconditioned response to an unconditioned stimulus is transmitted to a conditioned stimulus. The first systematic study on such a phenomenon was done by

  2. All individuals of an identical species respond similarly to stereotyped behaviour.
  3. Classical conditioning is also known as Pavlovian conditioning.
  4. Maximum behaviour is partially derived and partially learned.
Question 8 Multiple Choice (Single Answer)

There are particular centres and circuits in animals' nervous system which produce fixed and stereotyped responses to evidence stimuli.
What is this mechanism called?

  1. Effector mechanism
  2. Innate releasing mechanism
  3. Concept of motivation
  4. Sensory perceptual mechanism
Question 9 Multiple Choice (Single Answer)

If a male white-crowned sparrow is hatched and reared in separation, but at the time of crucial imprinting period (10-50 days after hatching) is allowed to hear a male’s song from any various sparrow species, then at maturity, the separated white-crown male will

Question 16 Multiple Choice (Single Answer)

Imprinting is the word utilised in psychology and ethology for describing any type of phase-sensitive learning which is fast and relatively independent of the result of behaviour. It was first utilised to explain the situation where an animal or individual learns the properties of some stimulus, which is accordingly known as “imprinted”.

Which of the following options defines the word ’imprinting’ as in animal behaviour?

  1. Time-dependent form of learning behaviour by exposure to indicate stimulus
  2. Native behaviour of the given animal which is usually determined
  3. Learned behaviour that an animal displays at the time of different stages of its life
  4. None of these
Question 17 Multiple Choice (Single Answer)

Imprinting is the word utilised in psychology and ethology for describing any type of phase-sensitive learning which is fast and relatively independent of the result of behaviour. It was first utilised to explain the situation where an animal or individual learns the properties of some stimulus, which is accordingly known as “imprinted”.

Which of following statements is correct regarding imprinting?

  1. It is not critical to usual behavioural development.
  2. It takes place only in birds.
  3. Its impact continues only for a short period of time.
  4. It is a fast form of learning.
Question 18 Multiple Choice (Single Answer)

Classical conditioning or Pavlovian conditioning is a type of learning where the conditioned stimulus (CS) appears to indicate the existence of the second stimulus, i.e., the unconditioned stimulus (US), which is a stimulus that causes a response in the organism. Conditioned response is a learned response to the early neutral stimulus. US is generally a biologically relevant stimulus like pain or food, which evokes a response from the start and is is termed as unconditioned response (UR).

Which of the following options give(s) the correct name for classical conditioning?

  1. Operant conditioning
  2. Pavlovian conditioning
  3. Both (1) and (2)
  4. None of these
Question 19 Multiple Choice (Single Answer)

Classical conditioning or Pavlovian conditioning is a type of learning where the conditioned stimulus (CS) appears to indicate the existence of the second stimulus, i.e. the unconditioned stimulus (US), which is a stimulus that causes a response in the organism. Conditioned response is a learned response to the early neutral stimulus. US is generally a biologically relevant stimulus like pain or food, which evokes a response from the start and is is termed as unconditioned response (UR).

Which of the following statements is correct regarding classical conditioning?

  1. An insignificant stimulus may evoke a response due to its co-relation with a common stimulus.
  2. An animal co-relates a behaviour with an award or punishment.
  3. An animal learns as the result of trial and fault.
  4. Sensitivity to worthless or repetitive stimuli takes place.
Question 20 Multiple Choice (Single Answer)
