A laundry treatment apparatus and a method of controlling the same are disclosed. The laundry treatment apparatus includes a tub for storing wash water, a drum provided in the tub for receiving laundry, an introduction port formed in the upper part of the tub for allowing laundry to be introduced therethrough, and a door for opening and closing the introduction port. The laundry treatment apparatus sequentially performs a washing cycle, a rinsing cycle, and a spin-drying cycle to wash the laundry. The method of controlling the laundry treatment apparatus includes determining whether bubbles have been generated in the tub within a period in which the washing cycle is performed while the drum is operated at a first rpm (a bubble determination step) and, upon determining at the bubble determination step that bubbles have been generated, operating the drum at a second rpm lower than the first rpm to perform the washing cycle (a first bubble reduction step).
