Prediction error (PE) is an important boundary condition for memory reconsolidation; however, while it is clear that a prediction error is necessary for reactivation, the parameters for what constitutes a prediction error are unclear. In the present study, participants watched a video with a positive emotional valence, followed by a baseline free recall test. One day later, participants completed one of three prediction error conditions (NoPE, 1PE, 2PE), followed by a visuospatial interference task (i.e., complex word search) or a nonvisuospatial multiplication control task. The NoPE condition viewed a photo and short summary of the video presented in a congruent modality (i.e., digitally on a computer monitor). The 1PE condition viewed the same photo and summary but received this information in an incongruent modality (i.e., on a piece of paper). The 2PE condition viewed the same photo and summary in an incongruent modality (i.e., on a piece of paper), plus one new fact added to the summary. Memory testing one week later showed a significant drop in free recall, but not recognition, for all groups from the first to the second free recall test; however, no differences were observed between groups. These results indicate that, in the positive film paradigm, minimal prediction errors (i.e., one or two changes) are not sufficient to destabilize memory. Given the importance of prediction error for applications of reconsolidation to the treatment of memory-based psychological disorders and drug addiction, further examination of the parameters for prediction error is warranted.

视觉空间干扰的预测错误参数:视觉空间词搜索干扰后,最小的预测错误会使正声明性存储器保持完整

预测误差(PE)是内存重新整合的重要边界条件。然而,尽管很明显预测误差对于重新激活是必要的,但不清楚构成预测误差的参数。在本研究中,参与者观看了具有积极情感价格的视频,随后进行了基线免费回忆测试。一天后,参与者完成了三种预测错误条件(NoPE,1PE,2PE)之一,然后进行了视觉空间干扰任务(即,复杂单词搜索)或非视觉空间乘法控制任务。NoPE条件以一致的方式(即,在计算机监视器上以数字方式)查看了照片和视频的简短摘要。1PE条件查看了相同的照片和摘要,但是以不一致的方式(即,在一张纸上)接收了此信息。2PE条件以不一致的方式(即,在一张纸上)查看了相同的照片和摘要,并且在摘要中添加了一个新事实。一周后的记忆力测试显示,从第一组到第二组免费召回测试,所有组的免费召回率均显着下降,但没有得到认可。但是,两组之间没有观察到差异。这些结果表明,在正片范式中,最小的预测误差(即一个或两个变化)不足以破坏存储器的稳定性。考虑到预测误差对于将重组应用于治疗基于记忆的心理障碍和药物成瘾的重要性,因此有必要进一步检查预测误差的参数。在摘要中添加了一个新事实。一周后的记忆力测试显示,从第一组到第二组免费召回测试,所有组的免费召回率均显着下降,但没有得到认可。但是,两组之间没有观察到差异。这些结果表明,在正片范式中,最小的预测误差(即一个或两个变化)不足以破坏存储器的稳定性。考虑到预测误差对于将重组应用于治疗基于记忆的心理障碍和药物成瘾的重要性,因此有必要进一步检查预测误差的参数。在摘要中添加了一个新事实。一周后的记忆力测试显示,从第一组到第二组免费召回测试,所有组的免费召回率均显着下降,但没有得到认可。但是,两组之间没有观察到差异。这些结果表明,在正片范式中,最小的预测误差(即一个或两个变化)不足以破坏存储器的稳定性。考虑到预测误差对于将重组应用于治疗基于记忆的心理障碍和药物成瘾的重要性,因此有必要进一步检查预测误差的参数。两组之间未观察到差异。这些结果表明,在正片范式中,最小的预测误差(即一个或两个变化)不足以破坏存储器的稳定性。考虑到预测误差对于将重组应用于治疗基于记忆的心理障碍和药物成瘾的重要性,因此有必要进一步检查预测误差的参数。两组之间未观察到差异。这些结果表明,在正片范式中,最小的预测误差(即一个或两个变化)不足以破坏存储器的稳定性。考虑到预测误差对于将重组应用于治疗基于记忆的心理障碍和药物成瘾的重要性,因此有必要进一步检查预测误差的参数。
