概括

使用条件刺激 (CS) 的帕夫洛夫训练显著减少了老鼠的冲动选择. 这种简短的培训方法鼓励选择更大的后期奖励 (LLR),而不是更小的早期奖励 (SSR).

科学领域:

  • 行为神经科学 行为神经科学
  • 动物的行为和认知.

背景情况:

  • 冲动选择,偏爱较小的早期奖励 (SSR) 而不是较大的后期奖励 (LLR),是一个重要的研究领域.
  • 目前减少冲动的方法需要大量的培训时间.

研究的目的:

  • 调查简短的帕夫洛夫训练程序在减少冲动选择方面的有效性.
  • 确定是否可以建立条件刺激 (CS) 来促进更大后回报 (LLR) 选择.

主要方法:

  • 40只雄性长埃文斯老鼠被分为食欲强的帕夫洛夫式或未配对的训练组.
  • 在帕夫洛夫训练中,杆插入标志着即将到来的食物奖励,将其确立为CS.
  • 评估了冲动选择,使用训练杆来选择LLR.

主要成果:

  • 帕夫洛夫小组中的老鼠表现出向杆CS的标志追踪.
  • 与未配对的小组相比,Pavlovian训练的老鼠的冲动选择明显减少.
  • CS有效地鼓励了LLR选择,减少了对SSR的偏好.

结论:

  • 一个简短的帕夫洛夫训练方案可以有效地减少非人类受试者的冲动选择.
  • 有条件的刺激可以被战略性地使用,以促进自我控制和延迟满足.
