INTRODUCTION

CORE DEFINITION

Cue-dependent forgetting holds that much of what we call forgetting is a retrieval failure rather than a decay of the memory trace. The information remains stored, but the cue that would access it is missing or mismatched, which is why an old smell or a familiar room can return a memory thought lost. It is closely tied to encoding specificity, where a cue works when it matches the conditions of encoding. The constraint is that this explains retrieval-based loss, not all loss: some material genuinely degrades.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Index Building: store knowledge with several deliberate cues rather than one. - Retrieve Not Relearn: when recall fails, hunt for cues before studying the material again. - Context Cue: use place, state, or sensory cues to reopen an access path.

Anchor fast decisions

A memory is addressed by the overlap between the current cue and the information encoded with the trace. If the overlap is zero, the trace cannot be activated even though it exists, which feels identical to having lost it. Adding cues at encoding widens the set of future addresses, so the same content becomes reachable from more starting points.

Tip of the Tongue

The tip-of-the-tongue phenomenon (TOT) is the common experience of being unable to retrieve a word from memory, often accompanied by partial recall and a frustrating feeling of being on the verge of saying it. The name originates from the English phrase "It's on the tip of my tongue." People experiencing TOT typically recall one or more features of the target word, such as one of its characters, words with similar sounds or meanings, or even a syllable of the target word.

Von Restorff Effect

The von Restorff effect, also known as the isolation effect, predicts that when multiple homogeneous stimuli are presented, the stimulus that differs from the rest is more likely to be remembered. The theory was coined by German psychiatrist and pediatrician Hedwig von Restorff (1906–1962), who, in …

Misinformation Effect

The misinformation effect occurs when a person's recall of episodic memories becomes less accurate because of post-event information. The misinformation effect has been studied since the mid-1970s.
