Cell phones have brought convenience to people in their lives, but they also bring many problems, such as addiction to cell phone use, or even no cell phone phobia. Research shows that parents addicted to cell phones, children are prone to become agitated, and perhaps also affect the parent-child relationship. Seventy percent of parents use cell phones when eating Boston Medical Center behavioral pediatrics expert Jenny Radetsky led a team of researchers to observe parents with children eating in fast food restaurants. In order to ensure that the subjects were not disturbed by the outside world, the observation was conducted in secret and the researchers kept a certain distance from the subjects. The team observed 55 parents with children under the age of 10. The researchers observed their children’s behavior according to the degree of access to their cell phones during meals, ranging from leaving the cell phone on the table to using it throughout the meal, and divided into five categories. Statistics show that one-third of parents use their cell phones from time to time during meals; 73% of parents use their cell phones at least once during meals; and more than 15% of parents use their cell phones near the end of the meal while their children are still eating. Parent-child relationship: children because of parents pay attention to the phone and disturbed Radetsky et al. study shows that when parents spend more time to pay attention to the phone, most of the children become restless, and try to get the attention of parents through their own behavior, but there are also children “self-indulgence” of the individual case. Recently, the British “Daily Mail” quoted Radetzky as saying: when the caregiver will be highly concentrated on their own hands of the device, they will ignore the child, or reduce the interaction with the child. And while children are entertaining themselves, a significant percentage of them are distracted from their parents’ actions, as well as wondering why their parents are using their cell phones. The study will be published in the April issue of Pediatrics. The question remains to be answered: Previous research has shown that children, especially newborns, learn about the world by making eye contact and develop language skills through a similar pattern. Lack of face-to-face communication and interaction between parents and children can affect the parent-child relationship and lead to developmental problems. The study by Radetsky et al. was the first to focus on changes in children’s behavior when parents use cell phones. More research needs to be done on the link between parents’ use of electronic devices and children’s behavior, and at this stage it is not conclusive. However, two experiments by psychologists at the University of Essex exploring the impact of cell phones on adult interpersonal interactions have shown that cell phones negatively affect closeness, communication, and quality of conversation. In face-to-face conversations, cell phones reduce empathy and human understanding, the researchers report in the Journal of Social and Human Relations. Empathy” in psychology refers to the ability to penetrate into the subjective world of another person and understand their feelings. In other words, the use of cell phones during meals reduces parents’ ability to understand their children’s feelings.
