伦理学伦理学伦理学
比较心理学比较心理学

背景情况:

动物无聊是一个研究不足的福利问题,难以区分于冷漠和抑郁.
区分这些负面状态需要了解动物对不同价值的刺激的反应.
养的猪,经常被安置在单调的条件下,是研究无聊的相关模型.

研究的目的:

在猪中为开发区分无聊与冷漠和抑郁的任务奠定基础.
评估刺激反应中的潜在与年龄相关的差异.

主要方法:

一个主体内设计使39只猪 (小猪和母猪) 暴露在12个预先分类的刺激中.
一个接近-避免范式测量了猪对刺激的反应.
统计分析检查了刺激,年龄及其对行为指标的相互作用的影响.

主要成果:

刺激价值显著影响了所有测量到的接近和回避行为.
根据观察到的猪反应,对五种刺激的价值分类被重新分类.
对于一些结果措施,发现了刺激和年龄之间的显著相互作用.

结论:

该研究成功验证并重新分类了猪的刺激价值.
调查结果为未来福利评估选择适当的刺激和结果措施提供了基础.

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated, individuals become less...
