Updating a situation model: a memory-based text processing view.

Previous research (J. E. Albrecht & E. J. O'Brien, 1993) demonstrated that readers were aware of an inconsistency between an earlier described characteristic of a protagonist and a subsequent target action carried out by the protagonist. In a series of 5 experiments, a qualification was added to the described characteristic that restricted the conditions under which the characteristic was operative. According to the here-and-now view of mapping, readers should use this qualification to maintain a fully updated model of the protagonist in active memory and should not experience comprehension difficulty when reading the target action. In contrast, according to the memory-based text processing view, the qualification would not be part of the active discourse model. Instead, it would be reactivated when the target action was read. Thus, readers should still experience comprehension difficulty. Results of all 5 experiments were consistent with the memory-based text processing view.

Accessing singular antecedents in conjoined phrases.

Two experiments examined processing of singular pronouns when the antecedent (e.g., Mary) was a noun phrase (NP) in a conjoined phrase (e.g., Mary and John). Whole-sentence reading times showed an increase in processing time associated with splitting the conjoined phrase to access a single NP antecedent. The increase in processing occurred both when the antecedent was in the subject position and when it was in a nonsubject position. The source of the disruption was further investigated using eyetracking methods. Summing over regions of the text, the magnitude of the processing cost incurred by having to split a conjoined NP was closely comparable when there was and when there was not a gender-appropriate distracting potential antecedent. When there was no such potential antecedent, the increase in processing time occurred immediately in the pronoun region when eye movements were measured. In contrast, when there was a second discourse entity that matched the gender and number of the pronoun (but was not a plausible antecedent for the pronoun), eyetracking measures suggested that the processing difficulty was delayed until additional information was read that forced the antecedent to be one of the conjoined NPs. The results are interpreted in terms of Sanford and Garrod's (1981) scenario-based model of text comprehension.

The role of perspective in the accessibility of goals during reading.

An implicit assumption of several causal reasoning models is that readers adopt the goals of a narrative's protagonist during text comprehension. In apparent violation of this assumption, readers participating in Experiment 1 of the present study drew inferences relevant to a protagonist's goal even when that goal was already satisfied from the perspective of the protagonist. In Experiments 2 and 3, participants were explicitly asked to view the text situation from the point of view of the protagonist. In this case, the goals of the reader and the protagonist should be the same. In these experiments, participants focused on the goals of the protagonist only when those goals had not been satisfied from the perspective of the protagonist. These results are discussed in terms of reader- and character-based perspectives and in terms of text characteristics that cue perspective taking.

Role of context in accessing distant information during reading.

In 3 experiments, the authors investigated factors that influence accessibility of backgrounded goal information. Participants read texts consisting of 2 episodes. In the 1st episode, the goal was satisfied or unsatisfied. Following a statement of goal satisfaction or goal postponement, there was a 2nd unrelated episode. After completion of the 2nd episode, target sentences were presented that were consistent with the 2nd episode but were inconsistent with completion of the earlier unsatisfied goal. Participants noticed the inconsistency only when the conflicting information was separated by a few sentences or when the context of the goal had been reinstated. The results are consistent with the resonance model described by J. E. Albrecht and E. J. O'Brien (1993) and by J. L. Myers, E. J. O'Brien, J. E. Albrecht, and R. A. Mason (1994).

Comprehension strategies in the development of a mental model.

It is generally assumed that the comprehension strategy used in the development of a mental model for narrative texts focuses on information that is relevant to the protagonist. Experiments 1a and 1b confirmed that readers remain sensitive to the location of the protagonist even when strategies based on text-base level representations predict this information should not be active. Experiments 2 and 3 tested the stronger claim that readers adopt the perspective of the protagonist. Ss did not notice information that was contradictory from the perspective of the protagonist unless explicitly instructed to adopt that perspective. It was concluded that, at the level of the mental model, readers focus on information relevant to the protagonist but that they do not adopt the perspective of the protagonist unless characteristics of the text induce such a strategy.

Effects of centrality on retrieval of text-based concepts.

Four experiments examined the effect of centrality on retrieval time using a wide range of testing conditions. Subjects read passages containing concepts that were rated as central, moderately central, or peripheral to a passage, and then were asked to retrieve those concepts. Experiment 1 used a probe recognition task that contained foils that were unrelated to the passage, and it was found that central concepts were recognized more quickly than peripheral concepts. In Experiment 2, the foils were passage related, resulting in a much larger recognition advantage of central concepts over peripheral concepts. Experiment 3 used a speeded-recall task. Again central concepts were recalled more quickly than less central concepts. Experiment 4 ruled out a simple strength argument. The results of all four experiments are discussed in terms of text being represented as an integrated network. Within this network, central concepts are more interconnected, providing additional access routes that facilitate retrieval.

Antecedent retrieval processes.

In three experiments we examined the nature of the search for antecedents during reading. Subjects read passages that contained two possible antecedents: one appearing early in the passages and the other appearing late. The degree of elaboration was varied, with one antecedent receiving additional elaboration for half the passages and the other antecedent receiving additional elaboration for the remaining half. Reading time differences from the first two experiments demonstrated that late antecedents are reinstated more quickly than early antecedents and elaborated antecedents are reinstated more quickly than nonelaborated antecedents. Experiment 1 showed that concepts that fall in the path of an antecedent search can be activated by the search. Experiments 2 and 3 showed that this activation is restricted to concepts that are from the same general category as the target antecedent.
