This new data provide insight into the long-debated question of whether language affects thought.
Doctoral candidate Banchiamlack Dessalegn and her mentor, Barbara Landau, the Dick and Lydia Todd Professor in the Department of Cognitive Science at Johns Hopkins, tackled that question via a query of their own: Would children who are given verbal cues while viewing mirror image visual patterns remember them more accurately, and longer, than would children who were not given those cues?
The answer, it seems, is yes.
"We learned that language, in the form of specific kinds of sentences spoken aloud, helped the children remember the patterns by 'gluing' their properties into memory," Dessalegn said. "We knew going in that children are very poor at holding onto any visual memory of objects that involve 'handedness:' meaning, whether something is facing left or right. Our results show that this kind of visual memory can be made stronger if the children are given a language 'mnemonic' device, such as 'The red part is on the left,' to stick that image into their memories longer."
In their experiments with normal 4-year-old children, Dessalegn and Landau displayed cards bearing red and green vertical, horizontal and diagonal patterns that were mirror images of one another. Half of the children heard, "Look! This is a blicket!" as they viewed the cards, but the other half heard only, "Look!" The patterns then were whisked away and three more cards appeared, only one of which bore the original pattern the children had seen. Though the investigators found that both groups performed better than chance, those who did make errors committed the same one: mistaking the original card for its mirror image.
"This showed us just how difficult it was for small children to commit both color and location to memory quickly," Landau said. The second experiment examined whether giving the children a verbal cue that specifically labeled color and location would improve their performance. This time, when they saw the pattern cards, the children heard, "The red is on the left." This group performed "reliably better" than the first, said Landau.
"The improvement was most likely due to the presence of relational language, which served as a mental pointer to the children," Landau said. "The bottom line is that language can help, but it has to be language that is specific and helps the children bridge the time gap between when they saw the pattern and when they could recognize it again."
Dessalegn explains it this way: "It's as if vision is saying, 'I only need help with keeping track of the location of each color,' and when language offers that information, and only that information, it takes it."
