By using the operant laboratory to study behavior, researchers have the benefit of being able to manipulate independent variables and measure the depending variables. Schedules of reinforcement can be divided into two broad categories: continuous reinforcement, which reinforces a response every time, and partial reinforcement, which reinforces a response occasionally. Reinforcements are distributed after a random number of responses. Fixed-ratio c. Variable-interval d. Variable-ratio e. Continuous.
