The present study examined the behavioral and affiliative differences between 2403 fifth grade students (1307 female, 1096 male) who reported that they belonged to a social group on social cognitive map (SCM) procedures and those who did not even though their peers viewed them as members of a peer group. Students who did not report their affiliations were more often classified as victims of bullying, have lower peer preference, have more peer-assessed internalizing symptoms, and have lower prosocial behavior and social prominence than students who reported their peer affiliates. Females with higher self-reported levels of aggression were more likely to report their peer affiliations. Males with higher self-reported levels of internalizing symptoms were less likely to report their affiliations. Implications and future directions are discussed.

本研究调查了2403名五年级学生（1307名女性，1096名男性）的行为和从属差异，他们报告说他们属于社会认知图（SCM）程序中的一个社会群体，即使他们的同龄人都不认为他们是同级组的成员。与报告同伴关系的学生相比，未报告隶属关系的学生通常被归类为欺凌的受害者，同伴偏爱程度较低，同伴评估的内化症状更多，亲社会行为和社会地位较低。自我报告的侵略水平较高的女性更有可能报告其同伴关系。自我报告的内在症状水平较高的男性报告其隶属关系的可能性较小。讨论了含义和未来方向。
