Description

Visual imagery is the deliberate formation of mental pictures to represent verbal or abstract content — scenes, spatial layouts, processes, or relationships. As an instructional element, it either prompts learners to generate their own images or supplies carefully chosen visuals that learners connect to the material, engaging both verbal and pictorial processing channels.

Design Implications

Imagery-based encoding improves recall and comprehension because information stored in both verbal and visual codes provides two retrieval routes instead of one Imagery-based dual encoding improves recall. [+S]. The effect depends on the image being relevant to the content's structure: images that merely decorate the page consume attention without adding referential connections Decorative illustrations do not improve learning. [+M]. Prompting learners to generate their own images ("picture what this paragraph describes") is often more effective than passive viewing, because generation forces active construction of the verbal–visual link.

Context

Requirements

• Content that has a mappable spatial, temporal, or structural analog — imagery of arbitrary verbal material yields little benefit
• Prompts or training that tell learners how to form useful images, not just that they should
• Images (supplied or generated) that depict the actual relationships in the content, not surface decoration (Annotating and sketching can externalize these images)

Constraints

• Imagery adds cognitive load when the content is already visually complex or the learner must hold too many image elements in working memory Imagery instructions can overload working memory for high-element-interactivity material. [~M]
• Less effective for abstract, non-visual content (formal logic, abstract syntax) where forced imagery produces misleading concrete analogs
• Learners with limited relevant experience may generate inaccurate images that then interfere with correct understanding [~W]
• Supplied images that are seductive but tangential reduce learning by diverting attention Decorative illustrations do not improve learning. [-M]

Target Learners

• Novices reading narrative, descriptive, or process-oriented text, who benefit from concrete referents for unfamiliar verbal content Imagery-based dual encoding improves recall. [+S]
• Young learners and learners with weak verbal decoding, for whom imagery provides an alternative encoding route
• Less beneficial for advanced learners who already form spontaneous images; explicit imagery instructions can be redundant Guidance becomes less effective as expertise increases. [~M]

Target Learning Goals

• Verbal recall and comprehension of descriptive or narrative material
• Spatial and relational understanding (anatomy, geography, mechanisms, story structure)
• Reading comprehension strategy use — imagery as a self-monitoring check for whether text is being understood

Affordances

• Dual Coding Theory — visual imagery is the learner-side enactment of this theory: pairing verbal input with imagery creates referential connections between the two coding systems
• Cognitive Load Management — a well-chosen image externalizes relationships that would otherwise have to be held in working memory verbally, freeing capacity for inference
• Activation — asking learners to picture a scene or process draws on prior experience to build the image, connecting new content to existing knowledge structures
• Chunking — a single integrated image can bind multiple verbal elements into one retrievable unit

Claims

• Concreteness fading enables learners to build a store of memorable images usable when abstract symbols lose meaning [+W]
• Text-only students based draw judgments on internal mental images while image-condition students recalled external visuals [~W]
• Students in the image condition gave higher draw judgment magnitude than text-only students in Study 1a [+W]
• LDI structure does not significantly affect cued recall of picture details or of interpretations themselves [~W]
• Congruent pictures paired with text facilitate reading comprehension better than text alone or pictures alone [+W]
• In Chun and Plass's CyberBuch studies, the text + picture annotation group significantly outperformed text-definition and text + video groups on a vocabulary test [+W]
• Subjects given image instructions include more nondiagnostic features in their drawings of concepts than subjects given discriminate instructions [-W]
• Explicit transfer instructions, in which trainees discuss how trained strategies could apply to a new task, produced reliable transfer of imagery and sentence-generation training to unpracticed text learning in older adults [+W]
• Imagery instructions yield more isolated concepts than discriminating-feature instructions, as shown by greater influence of nondiagnostic features on categorization accuracy [-W]
• Concepts become more interrelated with practice under discriminate instructions, and more isolated with practice under image instructions [-W]
• Spatial memory correlates with spatial imagery in the congenitally blind but not the sighted [~W]
• For uncertain architectural elements, geometric contrast yielded worse memory of appearance than no visualization, stop light colors, or both visualizations [-W]
• Effect sizes across drawing-support studies show significant heterogeneity for both comprehension and transfer outcomes [~W]
• Combining drawing with mentally imagining produces a negative effect of drawing, qualified by a significant interaction [~W]
• Positively emotional images in learning materials produce a learning effect and increase learner satisfaction compared to negative images [+W]
• Picture and gesture enrichment benefit children's learning of both concrete and abstract L2 words [+W]
• Accompanying sentences with an image improves comprehension accuracy, significantly so for sentences containing low-frequency words [+W]
• In literature teaching, a method using a sympathetic approach with opportunity for picturing and imaging the experiences in the selection was found superior to one stressing technique, analysis and factual detail [+W]

The evidence by question

• Does having learners form mental images of the material (imagery for text, the keyword mnemonic) improve learning, for whom, and how does it compare with other study techniques? Concreteness, imagery, and verbal associative processes play major roles across multiple educational domains [+M]
• Does pairing the words with a relevant visual of the same idea improve learning over the words alone, and for whom? Adding relevant pictures or graphics to text improves learning from it, with a small pooled effect on reading comprehension, though whether dual coding explains the benefit is disputed [+S]

Related Elements

• Analogies — a verbal counterpart to imagery; both map new content onto a familiar structure
• Advance Organizers — often visual-skeletal structures that imagery then fleshes out
• Annotating — sketching and diagramming externalize mental images and stabilize them for review
• Act It Out — enactive rather than imaginal embodiment of the same encoding principle
• Visual Imagery four-step spelling strategy used as the comparison intervention in the 1990 RCT

Examples

• Reciprocal Teaching (Palincsar & Brown) — includes "visualizing" as one of the comprehension strategies students are explicitly taught to apply while reading
• Keyword mnemonics in vocabulary instruction — learners form an interactive image linking a new word's sound to its meaning; a well-replicated imagery-based mnemonic, especially for foreign-language vocabulary
• Story mapping in elementary reading programs — learners picture and then sketch settings and character goals, converting narrative text into spatial imagery
