Explanation:
the substitution effect arises when as a result of a rise in the price of a good, the good becomes more expensive relative to its substitutes. Consumers not consume less of the good and more of the substitute. This leads to a movement up along the demand curve for that goods and not a movement along the demand curve for the good and not a shift of the demand curve. 
If the price of the good increases. The good becomes cheaper when compared with substitutes. As a result, the demand for the good increases while that of the substitutes decreases. 
The income effect is when an increase in price lowers consumer's purchasing power, holding money income constant.
