The purpose of the present experiment was to describe responding as a function of One‐to‐Many (OTM) and Many‐to‐One (MTO) training structures and identify baseline performances correlated with the accuracy level in tests for equivalence class formation. Participants were 42 adults assigned to either the MTO or the OTM groups, trained on 24 baseline relations, and assessed on the emergence of three 9‐member equivalence classes. Participants in the MTO group presented similar frequencies of responses to each of the comparisons throughout baseline training. Also, the number of trials required to meet the baseline mastery criterion was negatively correlated with test accuracy. Participants in the OTM group presented more variable frequencies of responses to each of the comparisons (participants tended to select some of the comparisons less often than others at the beginning of the training). In addition, the number of reinforced responses to the node presented as a sample during training was positively correlated with the number of correct responses during testing for the OTM group. The experiment contributed to an in‐depth stimulus control analysis of baseline and test performances, and its results have implications for understanding potential sources of variability between the training structures.

多对一和一对多结构下基线和等价类性能的描述性分析

本实验的目的是将响应描述为一对多 (OTM) 和多对一 (MTO) 训练结构的函数,并确定与等价类形成测试中的准确度水平相关的基线性能。参与者是分配到 MTO 或 OTM 组的 42 名成年人,他们接受了 24 个基线关系的培训,并评估了三个 9 人等价类的出现。MTO 组的参与者在整个基线训练中对每个比较的反应频率相似。此外,满足基线掌握标准所需的试验次数与测试准确性呈负相关。OTM 组的参与者对每个比较的反应频率变化更大(参与者在培训开始时倾向于选择一些比较的频率低于其他比较)。此外,在训练期间对作为样本的节点的强化响应数量与 OTM 组测试期间的正确响应数量呈正相关。该实验有助于对基线和测试性能进行深入的刺激控制分析,其结果对理解训练结构之间的潜在变异来源具有重要意义。在训练期间对作为样本的节点的强化响应数量与 OTM 组测试期间的正确响应数量呈正相关。该实验有助于对基线和测试性能进行深入的刺激控制分析,其结果对理解训练结构之间的潜在变异来源具有重要意义。在训练期间对作为样本的节点的强化响应数量与 OTM 组测试期间的正确响应数量呈正相关。该实验有助于对基线和测试性能进行深入的刺激控制分析,其结果对理解训练结构之间的潜在变异来源具有重要意义。
