Picture superiority effect

The tendency for images to be remembered better than corresponding words or other verbal information. It appears in recognition and recall, though its size depends on the task and materials.

Dual-coding theory: A theory that verbal and nonverbal information can be encoded in separate but interconnected representational systems. It explains the advantage by giving pictures both imaginal and verbal routes to retrieval.
Recognition memory: Memory expressed as identifying previously encountered information as familiar or previously seen. Picture advantages often appear in recognition tests that compare old and new items.
Picture-word superiority experiment: A laboratory comparison of memory for pictured objects and their corresponding verbal labels. This experimental paradigm directly operationalizes the effect through matched image-word materials.
Picture superiority effect in education: The use of pictures alongside instructional material to support memory for learned content. Instructional images can help learners retain concepts when they complement rather than distract from text.
Word superiority effect: The advantage of recognizing letters within words over recognizing the same letters in isolation. It reverses the direction of advantage by showing words can outperform simpler visual units.
Levels of processing: A framework in which memory depends on how deeply information is processed, from surface features to meaning. Pictures may prompt richer semantic and distinctive encoding than words in some tasks.
Recall (memory): Memory expressed by retrieving information without the target itself being presented. Recall tests reveal whether images help produce an item, not merely recognize it.
Picture superiority effect in paired-associate learning: A memory advantage for pictures over words when stimuli must be learned in paired associations. It tests the effect in relational learning rather than isolated-item recognition.
Multimedia learning: Learning from combinations of words and visual representations such as diagrams, animations, or pictures. It extends picture-based memory questions to coordinated verbal and visual instruction.
Von Restorff effect: The improved memory for an item that is distinctive within a set of otherwise similar items. It isolates distinctiveness, which can contribute to picture memory without requiring pictures.
