From the perspective of developmental psychology, Huang Lun-fen notes, a "one-to-one dependency" is the most important emotional experience of a person's early life and is the most important step in children's establishing a sense of trust and security. If this need cannot be met or is met only incompletely, children will not be able to successfully establish normal one-to-many relationships with their peers.
從兒童發展心理學來看，黃倫芬指出，「一對一的依附關係」，是人生早期最重要的感情經驗，也是孩子建立對人生的信賴感和安全感的最重要階段；這個階段若是不能滿足或有缺憾，就無法順利建立下一階段的、「一對多」的正常同儕關係。
