Subjects performed a task that involved learning a text and then indic
ating, for each of a series of pairs of words, whether they belonged t
o the same Sentence of that text. When the principle of argument overl
ap or causal coherence was the sole integrative factor in a text, nega
tive response times and error rates reflected distances in the network
representation predicted by the principle. When the two principles pr
edicted conflicting representations for a text, response times and err
or rates reflected the predictions of the principle of argument overla
p. The results were interpreted as suggesting that network connections
predicted by the two principles are both present in the memory repres
entations of texts and that causal connections are recorded at a more
abstract level of representation than are argument overlap connections
.
