Question

Which of the following statements is false?

a)

Instrumental conditioning is also called operant conditioning

b)

Instrumental conditioning was studied by Edward Thorndike and B. F. Skinner.

c)

Instrumental conditioning occurs when a behavior is associated with the occurrence of a significant event

d)

An example of instrumental conditioning is when a rat learns to press a lever in a box in the laboratory when lever pressing produces food pellets.

e)

All of the above are false

f)

None of the above are false

Which of the following statements is true?

A)

The soma receive information from thousands of other neurons and are the main source of input of the neuron

B)

Neurons are processes that extend outward from the soma, or cell body, and typically branch several times

C)

The axon of a neuron is covered with an insulating substance called a myelin sheath that allows the signal and communication of one neuron to travel rapidly to another neuron

D)

The axon, which is located within the soma, contains genetic information, directs protein synthesis, and supplies the energy and the resources the neuron needs to function

E)

All of the above are true

F)

A, B and C only are true

Explanation / Answer

1. (c) - Instrumental conditioning occurs when a behavior is associated with the occurrence of a significant event.

Explanation - The above statement is false because operant conditioning or instrumental conditioning described by B.F Skinner is a learning process in which the behaviour is modified by the inhibiting or reinforcing effect of its consequences. A rat wouldn't learn to press a lever if there's no association between pressing the lever and getting the reward in form of food pellets.

2. Option (c)

Explanation - Dendrites are processes that extend outward from the soma, or cell body, of aneuron and typically branch several times. So, option (b) is false. Axons are covered with a special insulating substance called myelin, which helps them convey the nerve impulse rapidly. So, the correct option is (c)

3. Option (b) - This is the definition of Contrast gain and so no explanation is possible.

4. Option (b)

Explanation - There are three layers in mammalian embryo namely endoderm (inner layer), the ectoderm (outer layer), and the mesoderm (middle layer)
