Victims selected gait
Assessing the human movement and co-ordination, there is much for him to understand. Maybe even too much. For example, to determine whether it is suitable for the role of the victim.
It is known that a small percentage of offenders commit most of all crimes. The same is true for the victims - some people are much more likely to be attacked. Back in the 1980s, psychologists from New York, Betty Grayson (Betty Grayson) and Morric Stein (Morris Stein) to film New York passers-by and showed them 53 prisoners serving sentences for attacks on strangers on the street and asked to evaluate who passer is more like a potential victim (1). On average, women and elderly people considered most vulnerable, but also among the young men were those who were criminals considered easy prey. The researchers then turned to professional dancers and asked to analyze the movements and gait of "victims." Dancers have determined that their coordination was worse than the others.
However, in the data do not fully believe: the problem is that, looking at the video, criminals could evaluate other factors, for example, clothes of passers-by. That is why, two decades later, a team of scientists from New Zealand under the leadership of Lucy Johnson (Lucy Johnson) decided to conduct a new study, excluding extraneous factors (2). They filmed gait of subjects dressed in black suit with attached joints of light sources. As a result, records are only visible points of light in place of the joints. Previously, it has been proven that watching the moving frame, we can determine the sex of a person and even his mood. The researchers found that in this case, the volunteers looked at the images, most often called some people easy prey for criminals. The researchers also wanted to find out whether the person using the exercise to change the coordination of movements, so that it no longer perceived as a potential victim. In the first experiment, groups of volunteers movement were evaluated before and after a brief self-defense course. No significant changes have occurred. In the second experiment, the subjects were taught to move more vigorously and synchronously - these factors, the researchers found, are most important in determining the "victims." After training, it became clear that the test has become less vulnerable (3). The positive effect remained even after repeated tests a month.
