UNASSIGNED:这项研究的目的是评估衰老犬的参与认知挑战性和潜在的令人沮丧的任务(不可能的任务)。根据以前的观察,我们预测,在其他认知测试和主人填写的问卷中显示认知障碍迹象的狗将显示对任务的参与减少。
UNASSIGNED:在此任务中,狗被展示在一个透明的容器中的一块食物,它们无法打开;测量与容器和实验者互动的时间。虽然不可能完成的任务还没有被用来衡量挫折,测试设计的参数会产生潜在的挫败状态,使这一评估适当。参加纵向衰老研究的32只狗参与了该研究。要求所有者完成两份认知功能障碍筛查问卷(犬痴呆量表[CADES]和犬认知功能障碍评定量表[CCDR])以及评估总体挫败感的问卷。狗参与了认知功能的多种测量以及不可能完成的任务。
UNASSIGNED:对于总(受损)CADES(p=0.02)和总CCDR(p=0.04)评分较高的狗,脱离不可能完成的任务的延迟更快。在观察社会线索的认知测试中,脱离接触的延迟也与表现下降相关(p=0.01),工作记忆(p≤0.001),空间推理和反转学习(p=0.02),持续关注(p=0.02)。
UNASSIGNED:与几种认知测量的高度相关性以及该测试的易于管理使其成为评估犬认知功能障碍综合征的有用工具,然而,目前尚不清楚挫折感或其他认知过程的增加是否有助于观察到的变化.
UNASSIGNED: The aim of this study was to evaluate the engagement of aging dogs with a cognitively challenging and potentially frustrating task (the impossible task). Based on previous observations, we predicted that dogs showing signs of cognitive impairment in other cognitive tests and owner-completed questionnaires would show reduced engagement with the task.
UNASSIGNED: In this task, dogs were shown a piece of food in a clear container that they could not open; time spent interacting with the container and the experimenter was measured. While the impossible task has not been used as a measure of frustration, the parameters of the test design creates a potential frustrate state, making this assessment appropriate. Thirty-two dogs enrolled in a longitudinal aging study participated in the study. Owners were asked to complete two cognitive dysfunction screening questionnaires (Canine Dementia Scale [CADES] and Canine Cognitive Dysfunction Rating Scale [CCDR]) as well a questionnaire assessing general frustration. Dogs participated in multiple measures of cognitive function as well the impossible task.
UNASSIGNED: Latency to disengage from the impossible task was faster for dogs with higher total (more impaired) CADES (p = 0.02) and total CCDR (p = 0.04) scores. Latency to disengage also correlated with decreased performance in cognitive tests observing social cues (p = 0.01), working memory (p ≤ 0.001), spatial reasoning and reversal learning (p = 0.02), and sustained attention (p = 0.02).
UNASSIGNED: The high correlation with several cognitive measures and the ease of administration of this test makes it a useful tool in evaluating canine cognitive dysfunction syndrome, however it is unclear if increased frustration or other cognitive processes are contributing to the observed changes.
