Experimental demonstration shows that discriminative performance transfers well between training formats, indicating their comparative effectiveness.

This research aims to compare the effectiveness of simultaneous and successive discrimination procedures in maintaining discriminative function.
Trained 10 undergraduate students in simple discrimination tasks using either a simultaneous or successive format.
Participants switched procedures to test for maintenance of discriminative function.
Measured performance accuracy and response latencies during testing.
Analyzed the interaction between procedure type and training phase.
Discriminative performance transferred nearly perfectly across procedures with high accuracy.
Simultaneous training required fewer blocks to reach the performance criterion.
Response latencies were significantly shorter in the simultaneous training condition.
Simultaneous-to-successive transfer was associated with longer latencies during testing.
A modified cumulative arousal model fit the successive group data well but underestimated simultaneous group learning.

Sabino et al. (2026) studied this question.
