limited reading, particularly towards the end of long texts.
Materials
The two short passages used in this experiment were both
descriptive in nature. One described characteristics of the bushmen
of South Africa, including a discussion of their history, habitat and
hunting rituals and the second text described various desert animals,
and how they have adapted to their environments. The number of words
in each text is presented in Table 1.
These passages were broken down into a set of propositions using
Turner and Green's (1978) system and were composed of 235-240 propositions.
To assess what was recalled by subjects, information
included in the recall protocols was matched against the list of
propositions that represent the content of each passage. The criteria
used to parse each passage into its constituent propositions
were used when comparing subjects' recall protocols to the proposition
list for each text. The two longer passages were expanded
versions of each of the short passages.
Procedure
In Experiment 2 subjects were assigned to the same text length X
reading format condition they were assigned to in Experiment 1.
Thus, for example, subjects presented short texts under limited
reading in Experiment 1 were also presented the short texts under
limited reading in Experiment 2. Half of the subjects in each text
length X reading format condition performed Experiment 1 first —
receiving the acquisition passages first after the various question-
