Equivalence classes with requirements for short response latencies.

Area of Science:

• Behavioral Psychology
• Cognitive Science
• Human Learning

Background:

• Conditional discriminations are fundamental to learning.
• Equivalence classes are complex learned relations.
• Rapid-responding contingencies may impede complex learning.

Purpose of the Study:

• To examine emergent conditional discriminations under strict time constraints.
• To determine if equivalence classes form despite limited response opportunities.
• To investigate the role of response latency in emergent relations.

Main Methods:

• Adult participants underwent matching-to-sample training with progressively shorter limited-hold durations.
• Fast-responding requirements were established for sample and comparison stimuli.
• Probe trials assessed emergent symmetry and transitivity without differential reinforcement.

Main Results:

• Three of five participants demonstrated emergent equivalence classes.
• Fast-responding requirements did not prevent the formation of these classes.
• Response latencies were slightly shorter during baseline and symmetry probes compared to equivalence probes.

Conclusions:

• Equivalence class formation is possible under stringent rapid-responding conditions.
• Limited time for mediating responses does not necessarily preclude complex emergent learning.
• Response latency differences were minimal, suggesting robust emergent performances.
