Such a \u2018retrieval mode\u2019 was proposed by Endel Tulving (1983), who considered it a neurocognitive state in which one keeps the goal of memory retrieval in mind. Building on Tulving&#8217;s proposal, we review converging evidence from multiple lines of research that emphasize the importance of internal states in the instantiation of retrieval modes that optimize successful remembering. <strong><span style=\"color: #ff0000;\">We identify three key factors that contribute to a retrieval mode by modulating either the likelihood or the content of retrieval<\/span><\/strong>: (1) <span style=\"color: #ff0000;\">an intention to remember or forget<\/span> (either in the present or the future), (2) <strong><span style=\"color: #ff0000;\">attentional selection of goal-relevant memories and suppression of distractors<\/span><\/strong>, and (3) <strong><span style=\"color: #ff0000;\">fluctuating levels of acetylcholine in the hippocampus<\/span><\/strong>. We discuss empirical evidence that these internal states individually influence memory retrieval and propose how they may interact synergistically. <strong><span style=\"color: #ff0000;\">Characterizing these dynamic internal factors is an important key for unlocking our understanding of the organization and accessibility of our memories<\/span><\/strong>.&#8221;<\/p>\n<p style=\"text-align: justify;\">Tarder-Stoll, Hannah, Manasi Jayakumar, Halle R.
