Drinking alcohol to fit into the group is described by

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Addiction

  2. Imitation

  3. Conditioning

  4. None of the above

Show answer
Correct Option: B
Explanation:

Copying the behaviour of someone observed is called imitation. It is seen in animals including humans as the most common learning process. Imitation is the social behaviour or conduct that a person unconsciously or passively learns and adopts. For example, drinking alcohol to fit into the group. It is observed that college students are influenced by peer pressure. They develop their concepts on the basis of the thought of peer groups. They want to be socially adapted by the group and they develop the habit of drinking. So, we can say that drinking alcohol is the temporary imitation of peer's behaviour.

Pavlov used dog to investigate .......... behaviour.

  1. Conditioning

  2. Instinct

  3. Imitate

  4. All of the above

Show answer
Correct Option: A
Explanation:

Dogs were used as an experimental model for the investigation of conditioning behavior and the experiment was done by Russian physiologist Ivan Pavlov and was recognized in the world by Pavlov's dog experiment based on classical conditioning theory in which he showed that they could be conditioned to unconsciously associated with neutral, unrelated event with feeding.

So, the correct option is 'Conditioning'

Which of the following animal imitate humans?

  1. Monkey

  2. Parrot

  3. Beluga Whales

  4. All of the above

Show answer
Correct Option: D
Explanation:

Imitation is a behavior where an organism learns from another and replicates or copies by observing. Many animals have this imitating behavior like parrot, pigeon, Japanese quailmonkey and beluga whales which imitate humans.

So, the correct option is 'All of the above'.

Which of the following behaviour is generated due to adrenaline rush?

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Instinct

  2. Imitation

  3. Conditioning

  4. Imprinting

Show answer
Correct Option: A
Explanation:

Instinct is a kind of behaviour which does not involve any prior learning and is inherent and automatic. When there is stimulus received, the release of adrenaline occurs which is known as the adrenaline rush. This results in the development of response which is automatic and instant. 

Thus, the correct answer is option A. 

Which of the following human behavior is more harmful than useful? 

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Conditioning

  2. Imprinting

  3. Instinct

  4. Imitation

Show answer
Correct Option: C
Explanation:

  1. Conditioning is a behavior in which a response becomes more frequent or predictive to a particular action or environment as a result of reinforcement.
  2. Imprinting is considered to be the kind of phase-sensitive learning that is very fast and does not depend on the consequences of behavior.
  3. Instinct is a type of behavior that is genetically present and is considered to be the response of a particular stimulus like fear from a snake.
  4. It is a behavior in which the human try and copy others things.
Since instinct behavior includes violence and ablility to kill each other inorder to protect itself, it is considered to be more hazardous.
So the correct option is 'Instinct'.

Belding's ground squirrel is a species whose females produce a shrill alarm call when predators are close by. The ground squirrels that sound this call are more likely to be eaten by those predators than those who do not sound alarm calls. This behaviour persists in the population of ground squirrels because

  1. Squirrels that sound the alarm call produce more offspring.

  2. The caller will attract a mate while sounding the call.

  3. The inclusive fitness of the caller is increased.

  4. All ground squirrels are born knowing how to do this because it is important.

  5. It increases the number of offspring the caller is able to leave behind since they are protected.

Show answer
Correct Option: D
Explanation:
The act of producing shrill alarm call in squirrels is a way of interspecies communication. Squirrels produce this shrill alarm call to make their partners aware of the danger due to the predator. Hence this is important for them to escape the predator.
So, the correct answer is 'All ground squirrels are born knowing how to do this because it is important'.

Which behaviour completely relies on stimulus?

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Instinct

  2. Conditioning

  3. Imitation

  4. None of the above

Show answer
Correct Option: B
Explanation:

Conditioning is the type of behavioral change which is shown towards the discriminative stimulus. The stimulus is added with some kind of attraction or extra benefits. The stimulus is often associated with a consequence. The strength of the behavior depends on the stimulus and the consequence. The type of behavior will always rely on the stimulus and its strength. When there is the certain attractive image used to describe an advertisement, this is done to attract the people to buy the product. 

Thus, the correct answer is option B. 

Which of the following factors affect the human behaviour? 

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Stimulus

  2. Genetics

  3. Nervous system

  4. All of the above

Show answer
Correct Option: D
Explanation:

A change which evokes a response is known as the stimulus. It greatly affects the human behaviour. The change in the external and internal environment act as a sudden stimulus and creates a response. The sequential change in the conditions greatly influence the human behavioural pattern.

The genes are the hereditary units which control the several characters. They get translated in the host and produces a protein which affects the human behaviour.
The autonomic nervous system releases hormones like epinephrine and norepinephrine which controls the sympathetic and parasympathetic response which have impact on human behaviour. 
So, the correct answer is option D.

Which of the following is the behaviour of social learning?
