Evidence of partial retrograde amnesia for episodic memories of no personal salience was found in head injured patients (n = 10) tested during posttraumatic amnesia or shortly after its resolution (n = 10), but there was no selective preservation of the earliest memories. In contrast, head injured patients tested during posttraumatic amnesia exhibited relatively preserved retention of early autobiographical memories which they recalled as accurately as oriented head injured patients. It is suggested that reminiscence of salient, early events increases their resistance to partial retrograde amnesia and contributes to the observed temporal gradient.
在创伤后遗忘期接受测试的头部受伤患者（n = 10）或在遗忘期结束后不久接受测试的头部受伤患者（n = 10）中，发现了对不具有个人显著性的情景记忆存在部分逆行性遗忘的证据，但最早的记忆并未被选择性保留。相比之下，在创伤后遗忘期接受测试的头部受伤患者表现出对早期自传体记忆的相对保留，他们回忆这些记忆的准确性与定向头部受伤患者相同。研究表明，对突出的早期事件的回忆会增加它们对部分逆行性遗忘的抵抗力，并导致观察到的时间梯度。
