八匹马在Y型迷宫中进行了测试，看它们是否会接近它们看到和听到食物被送入食物槽的那一侧。马在五个实验环境中进行测试：立即释放（IR），延迟释放3 s（3DR），6 s（6DR），9 s（9DR）和12 s（12DR）后，食物交付。个体受试者进行了5次IR试验，随后分别进行了5次3DR、6DR、9DR和12DR试验。1周后再次休息。数据进行了分析，通过对数线性分析frequency.Results分析表明，马能够实现正确的选择在IR试验期间，是成功的DR试验期间，并在重新测试期间略有改善。研究结果表明，马可能有一种可训练的前瞻性记忆，并从增量记忆训练中受益。然而，存在高估马认知能力的风险，不必要的强化延迟可能会导致马术中的福利和训练挫折。(C)2009爱思唯尔有限公司版权所有。
Eight horses were tested in a Y-maze to see if they would approach the side on which they had seen and heard food being delivered into a food trough. The horses were tested in five experimental contexts: immediate release (IR), delayed release 3 s (3DR), 6 s (6DR), 9 s (9DR) and 12 s (12DR) after food delivery. Individual subjects performed five IR trials, followed by five each of 3DR, 6DR, 9DR and 12DR trials. A re-rest was performed 1 week later. Data were analysed by log-linear analysis of frequencies.The results showed that the horses were capable of achieving the correct choice during IR trials, were successful during the DR trials and improved marginally during the re-test. The findings suggest that horses could have a trainable form of prospective memory and benefit from incremental memory-training exercises. However, there is a risk of overestimating equine cognitive ability and unnecessary reinforcement delays are likely to lead to welfare and training setbacks within equitation. (C) 2009 Elsevier Ltd.
