This study explored psychological conditions affecting children's rece
ptiveness to a newcomer (the guest) in a peer group entry task. Subjec
ts were 93 host dyads (48 male) of 7- to 9-year-old children. Hosts pl
ayed a word-naming game for 5 min before being joined by a male or fem
ale guest. The hosts' pre-entry interaction was coded to reflect an or
ientation toward the game (agentic) or toward each other and toward ex
perimental setting demands (communal). Hosts' psychological orientatio
n predicted entry outcomes. Specifically, hosts of excluded children v
erbally competed with each other (an aspect of agency) more than hosts
of children who entered Male hosts competed more than female hosts an
d female hosts helped and encouraged each other (aspects of the commun
al orientation) more than male hosts. These findings suggest that the
strategies and effort required by children to achieve group entry may
depend on prior psychological conditions attending the interaction of
the peer group.
