Abstract

A theoretical perspective on acquiring sight vocabulary and developing meaningful vocabulary is presented. Dual Coding Theory assumes that cognition occurs in two independent but connected codes: a verbal code for language and a nonverbal code for mental imagery. The mixed research literature on using pictures in teaching sight vocabulary is briefly reviewed, and a possible resolution suggested. The use of concrete, high-imagery words and both verbal and nonverbal contexts are found to be important factors in teaching sight vocabulary along with word decodability. Effective methods of teaching meaningful vocabulary that are consistent with Dual Coding Theory are briefly reviewed, including self-generated imagery, the use of illustrations, the keyword method, and verbal-associative methods. Results are relevant for both normal readers and those experiencing reading problems.

Our summary in plain words

What This Study Is About

This paper explores why some ways of learning new words work better than others. It looks at how our brains use both language and mental imagery—the ability to picture things in your mind—to understand and remember vocabulary.

How They Studied It

The author reviewed decades of existing research on how people learn to read and remember words. Instead of conducting a new experiment with a specific group of participants, this study analyzed various teaching methods through the lens of "Dual Coding Theory." This theory suggests that our minds have two separate but connected systems: one for processing language and one for processing non-verbal information, like images and sensations.

What They Found

The research shows that concrete words (like "apple") are much easier to learn than abstract words (like "justice") because they can be stored in both the verbal and the imagery systems of the brain. When we learn a word using both systems—for example, by seeing a picture or creating a mental image while hearing the word—we create two different "memory traces." This makes the information much more likely to be remembered. The study also found that techniques like the "keyword method," where learners associate a new word with a familiar-sounding word and a mental image, are among the most effective ways to build a vocabulary.

What This Might Mean

This suggests that for many people, "seeing" a word in the mind is a powerful tool for learning. However, for people with aphantasia—the inability to create mental images—traditional imagery-based learning strategies might not work the same way. It highlights the importance of understanding that different brains may need different strategies; while imagery helps many, others might rely more on the verbal system or logical connections. The study also cautions that while pictures help, they can sometimes be distracting if they don't focus the learner's attention on the right details.

One Interesting Detail

The study explains that concrete language has a "natural advantage" over abstract language because it is much easier for the brain to "code" it into both words and pictures simultaneously.

The role of load reduction instruction in assisting students with weak mental imagery

Martin and colleagues · Learning and Individual Differences

Among 1,451 high school students, weaker imagery went with lower science scores, a gap that was smaller where students said teachers reduced mental load. The authors suggest such teaching may help weak imagers, but the data cannot show cause.

Do low imagers know more words? examining the association between mental imagery and vocabulary size

Yavuz and Nazir · Language, Cognition and Neuroscience

In 158 English-speaking adults, how vividly people said they could picture things was not linked to the size of their vocabulary overall. Word by word, people with more vivid imagery did slightly worse on the most concrete words, such as tweezers or octopus, and in an exploratory comparison the 24 people with the weakest imagery scored higher than the 24 with the most vivid, about 82 against 76 out of 100. The authors suggest people with weak imagery may lean on word-based definitions, and call the findings provisional until they are repeated.

The relationship between multilingualism and visual imagery: Investigating aphantasia using the VVIQ

Li and Guan · Journal of Emerging Investigators

In an online survey of 302 Canadian students aged 16 to 18, those who said they were fluent in two or more languages rated their visual imagery as more vivid, on average, than those fluent in one. Ten students reported very weak or no imagery, and eight of them spoke one language. A one-time survey with self-rated fluency cannot show that languages change imagery, and the paper's figure that languages explain 97% of the differences in scores came from five group averages, one of them a single person.
