'Concurrent schedules of reinforcement' -- subject(s): Reinforcement (Psychology), Conditioned response

Ratio reinforcement schedules deliver reinforcement based on the number of responses emitted by the individual, while interval reinforcement schedules deliver reinforcement based on the passage of time and the first response after a specified time interval. Ratio schedules tend to generate higher response rates compared to interval schedules.

Four types of intermittent schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Fixed ratio schedules provide reinforcement after a set number of responses, while variable ratio schedules provide reinforcement after a varying number of responses. Fixed interval schedules provide reinforcement after a set time interval, while variable interval schedules provide reinforcement after a varying time interval.

A concurrent schedule is a type of schedule in which tasks or processes are executed simultaneously, often to increase efficiency and reduce overall execution time. It allows multiple operations to run concurrently, taking advantage of parallel processing capabilities in computer systems. This approach can lead to improved performance and resource utilization.

There are two kinds of reinforcement schedules. The first is continuous reinforcement where desired behavior is reinforced every time. The second schedule is partial reinforcement where a response is reinforced part of the time. Within partial reinforcement, there are four schedules which include fixed-ratio, variable-ratio, and fixed-interval and variable- interval.
