Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

科学领域:

  • 认知心理学 认知心理学
  • 教育心理学教育心理学
  • 神经科学是一个神经科学.

背景情况:

  • 在反之前进行预测可以改善与单独学习相比的长期记忆.
  • 在预测和反阶段注意力资源的作用尚未完全理解.

研究的目的:

  • 调查预测效应是否需要在初始预测或随后的反阶段注意力资源.
  • 为了确定学习不同阶段的注意力需求如何影响记忆保留.

主要方法:

  • 两项实验使用单词对学习,包括单独研究或预测试验.
  • 在预测试验的第一个或最后6秒内引入了分心 (次要任务).
  • 学习条件在完全注意力和分心之间有所不同,以评估注意力资源需求.

主要成果:

  • 在没有分心的情况下观察到预测效应.
  • 在初始预测阶段 (前6s) 的分心并没有消除预测效应.
  • 在反阶段 (最后6s) 的分心显著消除了预测效应.
  • 与初始测试阶段相比,当反阶段出现分心时,回忆障碍更大.

结论:

  • 注意力过程对于预测效果至关重要,特别是在反阶段.
  • 这些发现支持了理论模型,强调了注意力在记忆巩固中的重要性.
  • 记忆保留从预测中受益,但这种益处取决于在反过程中足够的注意力.
