Abstract

Reward is thought to attenuate forgetting through the automatic effect of dopamine on hippocampal memory traces. Here we report a conceptual replication of previous results where we did not observe this effect of reward. Participants encoded eight lists of pictures and recalled picture content immediately or the next day. They were informed that they could gain monetary reward for recalling the pictures, with the level of reward indicated through the frame surrounding the picture. Reward was manipulated both within and across lists. Bayesian statistics found moderate evidence for the null hypothesis that reward does not modulate forgetting in human free recall.

在自由回忆测试中，奖励不能调节遗忘。

奖励被认为是通过多巴胺对海马体记忆痕迹的自动作用来减弱遗忘。在这里，我们报告了先前结果的概念复制，我们没有观察到奖励的这种影响。参与者对八张图片列表进行编码，并立即或第二天回忆图片内容。他们被告知，回忆这些照片可以获得金钱奖励，奖励的等级通过照片周围的框显示出来。奖励在列表内部和列表之间都是被操纵的。贝叶斯统计发现了零假设的适度证据，即奖励不调节人类自由回忆中的遗忘。

期刊介绍： The neurobiology of learning and memory is entering a new interdisciplinary era. Advances in neuropsychology have identified regions of brain tissue that are critical for certain types of function. Electrophysiological techniques have revealed behavioral correlates of neuronal activity. Studies of synaptic plasticity suggest that some mechanisms of memory formation may resemble those of neural development. And molecular approaches have identified genes with patterns of expression that influence behavior. It is clear that future progress depends on interdisciplinary investigations. The current literature of learning and memory is large but fragmented. Until now, there has been no single journal devoted to this area of study and no dominant journal that demands attention by serious workers in the area, regardless of specialty. Learning & Memory provides a forum for these investigations in the form of research papers and review articles.
