The impact of individual differences on the performance of 2 roles-lea
rner and learning facilitator-was assessed during dyadic cooperative l
earning. Eighty university students, 40 men and 40 women, participated
in same-sex groups of 4. Each student cooperatively learned a text pa
ssage with 1 partner and then learned a 2nd passage with another partn
er. In a later session, the students recalled the information containe
d within both text passages and completed several personality measures
. A social relations analysis (D. A. Kenny & L. LaVoie, 1984) was used
to partition the variability in recall for the passages into various
sources. Variability in recall depended strongly on individual differe
nces in learning ability and (to a lesser extent) on individual differ
ences in the ability to facilitate others' learning. Differences in th
e ability to learn text passages were independent of individual differ
ences in the ability to facilitate others' learning. Effective learner
s were high in verbal ability, whereas effective learning facilitators
were low in public self-consciousness and in self-monitoring. The inf
luence of cognitive and rapport factors on the performance of the lear
ner role and the learning facilitator role is discussed.
