Gd. Lassiter et Kj. Apple, NEED FOR COGNITION AND THOUGHT-INDUCED ATTITUDE POLARIZATION - EXAMINING POSSIBLE DEMAND CHARACTERISTICS, Social behavior and personality, 26(1), 1998, pp. 99-103
Two sets of research demonstrate that individual differences in need f
or cognition moderate the effect of thought on attitude polarization.
However, one set indicates that a low need for cognition is associated
with greater thought-induced attitude polarization, whereas the other
set indicates that a high need for cognition is associated with great
er thought-induced attitude polarization. The present study provides e
vidence that the former, but not the latter, pattern of results may be
due to demand characteristics.
