使用离散试验选择程序,在 6 项实验中展示了雄性白化挪威大鼠 (N= 262) 的强化后信号处理。实验 I 评估了 Ss 能够在多大程度上将强化后信号持续时间与选择反应之间的关联知识转移到特定信号持续时间先于做出选择反应的机会的条件。在实验 II 中,通过使用信号持续时间和信号模态作为后强化信号的相关刺激属性,证明了传递效应的普遍性。实验 III 中研究了强化信号间隙和试验间隔的相对持续时间的作用。为了评估试验内和试验间信号关系对获得时间辨别力的影响,在实验 IV 和 V 中的每个试验中都呈现了强化前和强化后信号。实验 VI 中研究了强化前和强化后信号关系对跨 3 个信号范围的时间二分任务的稳态性能的影响。总体结果表明,大鼠很容易处理强化后信号的各种刺激属性,并且强化后信号、选择反应和强化前信号之间的关系是选择行为的主要决定因素。(39 参考)(PsycINFO 数据库记录 (c) 2016 APA,保留所有权利)
Demonstrated postreinforcement signal processing by male albino Norway rats (N= 262) in 6 experiments, using a discrete-trials choice procedure. Exp I assessed the extent to which Ss were able to transfer knowledge about associations between postreinforcement signal durations and choice responses to conditions in which a particular signal duration preceded the opportunity to make a choice response. In Exp II, the generality of the transfer effect was demonstrated by using both signal duration and signal modality as relevant stimulus attributes for the postreinforcement signals. The role of the relative durations of the reinforcement-signal gap and the intertrial interval was investigated in Exp III. To assess the effects of within-and between-trial signal relations on the acquisition of a temporal discrimination, both pre-and postreinforcement signals were presented on each trial in Exps IV and V. The effects of pre-and postreinforcement signal relations on the steady-state performance of a temporal bisection task across 3 signal ranges were studied in Exp VI. Overall results suggest that rats readily process various stimulus attributes of postreinforcement signals and that relations among postreinforcement signals, choice responses, and prereinforcement signals are major determinants of choice behavior.(39 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
