This work examined whether semantically relevant schemas could facilitate learning in the transverse patterning (TP) task, which requires participants to learn the value of each stimulus in relation to the stimulus with which it is paired (e.g., A wins over B, B wins over C, C wins over A). Younger and older adults received the standard TP in isolation (alone condition), with additional sessions (practice condition), or with 2 TP sessions, which used familiar stimuli with known relations (e.g., rock-paper-scissors, semantic condition). Accuracy improved when training was provided within the context of a previously known relational framework, beyond the benefits obtained with extended practice with the task. When levels of education and vocabulary scores were considered as covariates, age-related deficits in accuracy were observed in the alone and practice conditions but were eliminated in the semantic condition. Extended practice and appealing to prior knowledge improved explicit awareness for the stimulus contingencies for each age-group. Thus, age-related deficits in learning relations among items may be remediated using existing relational information within semantic memory as an analog for new learning.
这项工作研究了语义相关的图式是否可以促进横向模式化(TP)任务的学习,该任务要求参与者根据与其配对的刺激来学习每个刺激的价值(例如,A 赢 B,B 赢 C,C 赢 A)。年轻和年长的成年人分别接受了标准的 TP 孤立(单独条件)、附加会话(练习条件)或 2 个 TP 会话,这些会话使用熟悉的具有已知关系的刺激(例如,石头剪刀布,语义条件)。当在先前已知的关系框架内提供训练时,除了通过任务的扩展练习获得的益处外,准确性会提高。当考虑教育水平和词汇分数作为协变量时,在单独和练习条件下观察到与年龄相关的准确性缺陷,但在语义条件下消除了这些缺陷。扩展练习和利用先验知识提高了每个年龄组对刺激关联的明确意识。因此,使用语义记忆中现有的关系信息作为新学习的模拟物,可以纠正项目之间关系学习方面的与年龄相关的缺陷。
