Emergence of a three-sample conditional discrimination as foundation for reasoning capabilities

Area of Science:

• Behavioral Psychology
• Cognitive Science
• Learning Theory

Background:

• Conditional discrimination is a fundamental learning process.
• Relational stimuli play a crucial role in complex learning.
• Emergence of new behaviors from learned associations is a key area of study.

Purpose of the Study:

• To investigate the emergence of three-sample conditional discrimination.
• To determine the role of relational stimuli in emergent behaviors.
• To explore the potential for this procedure to foster reasoning capabilities.

Main Methods:

• Participants learned first-order conditional discriminations (AB, PQ, CD).
• A second-order conditional discrimination (XAB) was taught using relational stimuli (X1 for related, X2 for unrelated).
• Emergence of new conditional discriminations (PQX, XCD) was probed, followed by a final three-sample conditional discrimination.

Main Results:

• Participants demonstrated emergent conditional discriminations based on learned relations between stimuli.
• The presence of relational stimuli (X1, X2) was critical for the emergence of these discriminations.
• Omitting the relational stimulus training significantly reduced emergent behavior.

Conclusions:

• A novel form of emergent behavior, analogous to analogical reasoning, was demonstrated.
• Relational stimuli are essential for establishing complex conditional discriminations.
• This procedure offers a potential learning foundation for developing reasoning skills.
