Effects of feedback

Effects of feedback

Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Summary

Visual performance feedback (VPF) significantly increased behavior-specific praise (BSP) among targeted and non-targeted staff in a day-treatment program. This method enhanced praise-to-correction ratios, improving treatment fidelity.

Area of Science:

Behavioral Psychology
Child Psychology
Educational Psychology

Background:

Behavior-specific praise (BSP) is crucial for children with behavior disorders.
Maintaining high rates of BSP in day-treatment programs is challenging.
Previous studies on visual performance feedback (VPF) focused on researchers providing data to targeted staff.

Purpose of the Study:

To assess VPF's impact on BSP use by targeted and non-targeted staff in a day-treatment program.
To evaluate VPF's effectiveness with non-certified staff.
To determine if staff collecting VPF data influences their own BSP use.

Main Methods:

A multiple baseline with reversal design was employed.
Staff instructors collected VPF data.
BSP rates and praise-to-correction ratios were measured.

Main Results:

VPF doubled BSP rates in directly targeted staff.
VPF increased BSP rates by over 50% in non-targeted instructors who collected data.
Three out of four participants showed improved praise-to-correction ratios during VPF intervention.

Conclusions:

VPF is an effective strategy for increasing BSP in day-treatment settings.
Empowering staff to collect data enhances their own BSP use.
VPF can improve treatment fidelity and potentially reduce supervision time.
