Role of Shaping in Operant Conditioning

Role of Shaping in Operant Conditioning

Shaping is a technique used in operant conditioning to train complex behaviors by rewarding successive approximations toward the target behavior. This method is necessary because organisms are unlikely to perform complex behaviors spontaneously. Instead, shaping breaks down the desired behavior into small, manageable steps.
The steps involved in shaping begin with reinforcing any response that resembles the desired behavior. For example, parents might praise a child for picking up one toy. As...

Summary

Online infant studies may not replicate lab findings. Infants did not show shape discrimination online, suggesting limitations of current remote methods for developmental psychology research.

Area of Science:

Developmental Psychology
Cognitive Science
Human-Computer Interaction

Background:

Online developmental psychology studies are crucial due to pandemic-related research suspensions.
Previous laboratory studies demonstrated infants' sensitivity to basic shape information.

Purpose of the Study:

To investigate the viability of online studies for infant shape discrimination.
To compare online results with established laboratory findings.

Main Methods:

Two unmonitored online experiments were conducted.
A change-detection looking-time paradigm was used with 96 7-month-old infants.
Stimuli were presented on personal computer screens.

Main Results:

Infants did not exhibit measurable shape discrimination sensitivities online.
Distraction in online experiments did not reliably predict shape discrimination ability.
Findings contrast with previous laboratory-based observations.

Conclusions:

The change-detection paradigm may be ineffective online due to screen size and stimulus presentation.
Online developmental paradigms may not yield consistent results compared to controlled lab settings.
Methodological validation is essential for online developmental science research.
