Which among the following is a simple act of learning that involving loss of sensitivity to unimportant stimuli?

  1. Reasoning/insight

  2. Imprinting

  3. Classical conditioning

  4. Habituation

  5. Instinct
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Instinct is a kind of behaviour which does not involve any prior learning and is inherent and automatic. Thus, the loss of sensitivity to unimportant stimuli is a natural act which is instinctive in nature. For example, dancing of honeybees in the direction of food, animal fighting and courtship behaviour are are instinct behaviour.

Read the following passage and answer the following question.
A group of 10 newly hatched chicks was separated into two smaller groups containing five chicks each. One group (Group A) was left with the mother hen, the other group (Group B) was taken shortly after hatching and kept with a mother goose. The chicks in Group A displayed normal behavior and followed the mother hen around. The chicks in Group B followed the mother goose around and exhibited goose like behavior, such as swimming. After one week, Group B was reunited with the mother hen, but ignored her, and instead continued to follow the mother goose around the barnyard.
The behaviour exhibited by the chicks in Group B is

  1. Imprinting

  2. Instinct

  3. Insight

  4. Habituation

  5. Conditioning
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A form of learning that occurs during a brief genetically determined critical period shortly after birth is called as imprinting. Instinct is an inborn behaviour characteristic to a species and is often a response to specific environmental stimuli. Conditioning is also a learned response in which stimulus becomes associated with a consequence. Habituation is the most complicated form of learned behavior and includes applying something already learned to a new situation without a period of trial and error. Reasoning is making concept about cause and effect in particular context. Because the chicks learnt to follow mother goose and mother hen just after birth; it is imprinting. 

Thus, the correct answer is option (A).

Which of the following occurs only at a certain, critical time in an animal's life?

  1. Dominance

  2. Reflex

  3. Instinct

  4. Imprinting

  5. Habituation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Imprinting is a form of learning that occurs during a brief genetically determined critical period shortly after birth. Habituation is the most complicated form of learned behavior and includes applying something already learned to a new situation without a period of trial and error. The reasoning is making the concept of cause and effect in particular context. Reflex and dominance occur during a late phase of life. 

Therefore, the correct answer is option D.
