OperantKit

OperantKit is a tool kit for operant conditioning (instrumental conditioning) experiments written in Swift.

Usage

import OperantKit
import RxSwift

func main() {
    let schedule = FR(5) // Fixed ratio 5 schedule
    let events: Observable<Void> = ... // Observable events
    schedule.decision(events)
        .filter { $0.isReinforcement } // Filtering responses of reinforcement
        .subscribe(onNext: {
            print("Reinforcement")
        })
        .disposed(by: DisposeBag())
}

Examples

Supporting schedules

Simple schedules

Fixed schedules

Name of schedule	Code
Fixed ratio schedule	`FR(5)`
Variable ratio schedule	`VR(5)` ※
Random ratio schedule	`RR(5)`

※ The number of iterations of the variable schedule is “12” by default,

VR(10, iterations: 12)

It is also possible to change the number of iterations and so on.

Interval schedules

Name of schedule	Code
Fixed interval schedule	`FI(5)`
Variable interval schedule	`VI(5)`
Random interval schedule	`RI(5)`

The time interval defaults in .seconds,

FI(5, unit: .minutes)

It is also possible to change the unit in such a way.

Time schedules

Name of schedule	Code
Fixed time schedule	`FT(5)`
Variable time schedule	`VT(5)`
Random time schedule	`RT(5)`

The time interval defaults in .seconds,

FI(5, unit: .minutes)

It is also possible to change the unit in such a way.

Other schedules

Name of schedule	Code
Continuous reinforcement	`CRF()`
Extinction schedule	`EXT()`

Compound schedules

Name of schedule	Code
Concurrent schedule	`Conc(FR(5), VI(10))` ※

※ When a common schedule applies to two or more types of operandam like the internal link in concurrent chained schedule, it can be handled by using Shared() keyword. e.g. Conc(Shared(VI(10)))
