Job and organizational changes have promoted the importance of social skill
at work, yet research in this area has been limited. The authors investiga
ted the interaction between social skill and general mental ability (GMA) i
n the explanation of job performance and salary, controlling for personalit
y and demographic characteristics. The results indicated that the relations
hips between social skill and job performance were stronger among workers h
igh than low in GMA. In a similar manner, the relationships between GMA and
job performance were stronger among workers high than low in social skill.
The interaction on salary indicated that increases in social skill (or GMA
) for high-GMA (or social skill) individuals were associated with higher sa
lary levels. It is interesting, however, that increases in social skill (or
GMA) for those low in GMA (or social skill) contributed to lower salaries.
Implications of these results and directions for future research are discu
ssed.
