Controls in Experiments

When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

    Area of Science:

    • Computer Science
    • Behavioral Science
    • Pharmacology

    Background:

    • Traditional behavioral experiment control systems can be expensive and complex.
    • There is a need for accessible, integrated systems for data acquisition and experimental control.

    Purpose of the Study:

    • To describe a self-contained microcomputer control system (MCS) for behavioral experiments.
    • To demonstrate the system's utility in operant research within behavioral pharmacology.

    Main Methods:

    • Utilized a Rockwell AIM 65 microcomputer with BASIC language for system control.
    • Integrated a printer, alphanumeric display, 4K RAM, 8K BASIC ROM, cassette interface, and power supply.
    • Incorporated a control interface with 16 inputs, 16 outputs, a real-time clock, and machine language subroutines.

    Main Results:

    • The developed MCS is a compact, self-contained unit.
    • The system effectively controls and records real-time events from behavioral experiments.
    • BASIC proved to be a suitable user language for this microcomputer control system.

    Conclusions:

    • The microcomputer control system offers a cost-effective solution for behavioral research.
    • The system's design facilitates real-time event control and recording.
    • This MCS is well-suited for applications in behavioral pharmacology, particularly operant research.
