The hypothesis was tested that the Name-Letter Effect or affective ove
rvaluation of own name-letters as compared to non-name-letters (Nuttin
, 1985, 1987) is due to an enhanced subjective frequency of own name-l
etters as compared to non-name-letters. Experiment 1 yielded a Name-Le
tter Effect and an overestimation of own name-letters' frequencies as
compared to non-name-letters. Both effects were correlated. Experiment
s 2 and 3 replicated both effects but not their correlation. In Experi
ment 3, subjects who were satisfied with their own name showed a stron
ger Name-Letter Effect (but no stronger name-letter frequency overesti
mation) than subjects who were relatively dissatisfied with it. Result
s run counter to the subjective frequency hypothesis and support the m
ere ownership hypothesis, which states that merely belonging to one's
self (mere ownership) is a sufficient condition for the enhancement of
the attractiveness of an object and its constitutive elements. The im
plications of both name-letter overvaluation phenomena for cognitive a
nd affective self-referent processes are discussed.
