An example of an equivalence problem is shown here:. Students had to decide what number to put in the blank, to make the right side equal to the left. For example, in the above equation, the number seven belongs in the blank, so that both sides equal The teacher taught half the kids using just speech. All students were then tested on the equivalence problems twice: Posttest 1 was immediately after learning and Posttest 2 was 24 h later.
The students were also given a Transfer Test. The researchers wanted to determine whether the children could extend their knowledge of equivalence to other types of problems using similar rules. For example, third and fourth graders solved a multiplication equivalence problem such as:. Second graders, who were not quite ready for multiplication, solved more complicated addition problems on the Transfer Test, which did not have any of the same numbers on both sides, such as:.
The scientists compared the number of correct answers from children who saw gestures to those of the children who were taught with only speech. On Posttest 1, Posttest 2, and the Transfer Test, the students who saw gestures scored better than the students who only learned with speech. Figure 2 shows the difference between these two groups of children.
Furthermore, students who learned with gestures also performed significantly better on Posttest 2 than they had on Posttest 1. This showed that gestures not only helped students learn better but gestures also helped their performance get better over time. Students who learned with only speech did not perform better on Posttest 2 than they did on Posttest 1.
Not only do students learn better when their teacher gestures but they also learn better when they use gestures themselves. A group of scientists studied whether third and fourth graders learned math better when they gestured during class [ 3 ]. The teachers taught the students how to solve addition equivalence math problems like the ones above. After instruction, all students took a posttest that consisted of new addition equivalence problems.
Then, 4 weeks later, all students completed a follow-up test with similar types of questions. The follow-up test allowed the researchers to test if gestures helped learning over time. Students from all three conditions performed similarly on the posttest that they completed right after learning: making gestures when learning did not benefit learning immediately.
However, on the follow-up test 4 weeks later, the students who learned by only making gestures and the students who learned by making gestures along with speech performed better than the students who learned only by speech Figure 3. The researchers think that gesturing during learning helped the children produce stronger memories, because while gesturing they activated motor areas of the brain that were not activated in children who did not gesture.
We have now shown you that gestures can improve learning, both when children see other people using gestures and when the children themselves use gestures. Is there something about gestures that can help us know when children are ready to learn something new? This seems to be the case for babies learning language. Before babies can talk, they communicate by pointing. Between 9 and 12 months, babies begin pointing to request objects like a bottle or a toy. The use of these early gestures tends to predict the first words that babies say a few months later.
Babies usually say their first word at about 12 months. Before babies begin to combine multiple words together, they combine words and gestures. These combinations are called gesture-speech mismatches because the information in speech and gesture is different, or mismatched. In fact, these mismatches predict how well the babies will learn language: babies who produce more of these gesture-speech mismatches when they are 18 months old go on to produce more complex sentences when they are 3 years old!
In these cases, gestures tell us what the child already knows and help us predict when the child will learn new words. Researchers were curious about whether gestures predicted learning in school-age children as well. The researchers studied the gestures children made when explaining how they solved mathematical equivalence problems, like the ones described earlier [ 5 ].
The researchers thought that, even though children might not be able to communicate how to solve these problems using speech, they might express some knowledge of equivalence in their gestures.
However, it might be evident from their gestures that the children are beginning to understand that the two sides of the equation are separate units. For example, the student might sweep his or her hand first under the left side of the equation and then under the right side, like the teachers did in the experiment above. The researchers wondered whether gesturing toward each side of the equal sign separately was signaling that the child was beginning to understand the concept of equivalence but could not yet form the idea into words.

Gesture for Communication Like the study of spoken language, which can be characterized by its parts e. Gesture for the Listener Perhaps the most obvious communication benefits of gesture are those produced for the listener.
Gesture for the Speaker While it may seem intuitive that gesture has functions for the listener, gesture also has important benefits for the speaker. Gesture for Cognition Unlike speech, the spontaneous gestures that speakers produce have no standardized form, but rather, are idiosyncratic.
Gesture Reduces Cognitive Load Given that speakers gesture more when a task is cognitively or linguistically complex Melinger and Kita, ; Kita and Davies, , it is critical to understand how gesture confers cognitive benefits. Spontaneous Gestures Predict Readiness to Learn Our hands not only reveal what we know but also what we are about to know. People will want to hear your second, third, etc.
This is a powerful persuasion technique. This is when you hold your hands in the steeple, but lower. And instead of your fingers pointing up, they point more forward.
Kennedy, Khrushchev, This is a great gesture you can use in a one-on-one conversation. Kennedy was famous first for using this. An emphatic, it does not exhibit the anger of the clenched fist or pointing finger, and so is thought to be less threatening. Kennedy, who can be seen using it in many speeches and images from his political career.
You can emphasize this by assuming a thinking pose. Like this one, by putting your finger to your chin and looking up slightly. First, figure out WHAT you want to say. It could be on a big stage at a conference.
At your sisters wedding. Or in a meeting at work. So, slightly exaggerated gestures are okay. Practice exaggerated gesturing in private. However, experts agree …. You see the problem, right? So, I have my go-to gestures now. Before you start using any hand gesture, be aware that some gestures have different meanings in different places.
For example …. English speaking countries usually count with the index finger as the first digit. Many European countries start counting with the thumb as the first digit. But there is no word or links to your sites that you have build.
