Lj. Shrum et Tc. Oguinn, PROCESSES AND EFFECTS IN THE CONSTRUCTION OF SOCIAL-REALITY - CONSTRUCT ACCESSIBILITY AS AN EXPLANATORY VARIABLE, Communication research, 20(3), 1993, pp. 436-471
This study conceptualizes the cultivation effect in terms of the acces
sibility of information in memory. Contemporary social cognition resea
rch indicates that individuals consistently use the most accessible in
formation in memory as a basis for a variety of judgments. Consistent
with this body of literature, the current study demonstrates that, bas
ed on a reaction time task, those subjects who watch comparatively mor
e television not only overestimate frequency or probability but also g
ive faster responses to various types of cultivation questions. These
results support the notion that relevant information, presumably ''cul
tivated'' from television viewing, is more accessible in memory for he
avier viewers, and, consistent with predictions made by the availabili
ty heuristic literature, overestimations of frequency or probability a
re associated with this enhanced accessibility. Moreover, when control
ling for speed of response in the correlation between television viewi
ng and social reality estimates, the relationship is diminished or dis
appears entirely, suggesting that enhanced accessibility of relevant i
nformation for heavier viewers can at least partially account for the
cultivation effect.
