Body posture affects memory and learning infant reveals a robot
Researchers from Indiana University (IU), in the US, have discovered that the position is critical in the early stages of the acquisition of new knowledge. The study, led by psychologist Linda Smith and performed in collaboration with an expert in robotics England and an evolutionary psychologist at the University of Wisconsin-Madison, offers a new approach to the study of the relationship between the “objects of cognition” (as words or memories of physical objects) and body postures.
“This study shows that the body plays a role at the beginning of learning; and also how children use body positions in space to connect ideas, “Smith said in a statement UI.
The researchers examined through babies and a robot that was used as a model of children, the role of body position in the brain’s ability to “map” the names of objects. And they discovered that the coherence between body position and spatial relation to an object or the name of an object called out was critical to properly connect the object name with the object in question.
“Studies suggest that memory is closely linked to the location of an object,” Smith explains. “None, however, have shown that the body plays a role or position, if that position is changed, we forget”.
To reach these conclusions, scientists conducted a series of experiments, first with robots programmed to map the name to an object through its association with a stand; and then with children between 12 and 18 months.
In one experiment, first was shown to a robot an object at the left, and then a different one to its right. The process was repeated several times to create a partnership between objects and both positions of the robot. After this, the researchers presented two objects at the two locations, as they were repeating their names. This caused the robot is rotated and from migrating to the object associated with each name.
Consistently, the robot indicated a connection between the object and its name during the 20 repetitions of the experiment. But in subsequent tests, where objects were placed equally on both -so locations were not associated with a position specifically the robot failed in the examination.
When this test was replicated with children, only minor differences in the results were found: small data such as robot, revealed a relationship between posture and learning the names of objects.
Smith concluded from these results that their experiments “can provide a new way to investigate the connection between cognition and body; and new evidence that mental entities such as thoughts, words or representations of objects-that seem to have a space or body component, first take shape (in our minds) through the spatial relationship of body with the world around us. ”
