Loneliness: The Experience of Emotional and Social Isolation
1. The Study of Loneliness
According to Robert S. Weiss, in “Loneliness” in the MIT Press 1973, p 7-30, even though there has been little research on loneliness(p.9), “useful distinction between emotional and social isolation”(p.19) was built, and its effect is depend on ages, gender, and wealth(p.26).
The writer explains the reason that few psychologists or sociologists have studied the ordinary loneliness of ordinary people is neglect of loneliness (Weiss, 1973, p.9). He say “Loneliness is much more often commented on by songwriters than by social scientists” Frieda Fromm-Reichmann also noticed that “the absence of attention to loneliness was to be explained not by the challenge loneliness presented to understanding but rather by the threat it presented to well-being (Weiss, 1973, p.10).
However, Weiss established a distinction between two sorts of loneliness: emotional isolation and social isolation (1973, p.19). According to Weiss, first one “results from the loss or lack of a truly intimate tie (usually with spouse, parent, or child)” (1973, p.20) and second one is “consequence of lacking a network of involvements with peers of some sort” such as fellow workers, kinfolk, neighbors (1973, p.22)
Also, Weiss explains specific group of people are more vulnerable to loneliness. Through a telephone survey, he figure out that women are easier to feel lonely and it is more sever as they get older (1973, p.26). Weiss adds poor people are more likely to be lonely comparing to rich people (1973, p.27).
