The articles in this special issue take an important step in beginning to test the PET framework. Together, these articles illustrate the importance of considering individual differences in attitudes and prior knowledge as well as differences in task demands when investigating the role of emotions in shaping cognitive processing while reading…

Text comprehension involves the ability to understand how texts relate to the situation they describe and to each other (i.e., a Document model). Research into Document models has emphasized the role of information sources in structuring readers' mental models of situations. The present article reviews research on source comprehension and examines…

The coherence threshold marks the point at which a reader has gained a sufficient comprehension level to move on in a text. Previous research has demonstrated that the readers' coherence threshold can be manipulated by increasing or decreasing task demands. The present experiments examined a manipulation of the coherence threshold within the text…

Studies investigating the effect of connectives on comprehension have yielded different results, most likely because of differences in methodology and limited samples of texts and readers. We added and removed causal, temporal, contrastive, and additive connectives in 20 authentic Dutch texts. Dutch adolescents (n = 794) differing in reading…

This study was conducted to investigate two factors that affect the processing of the outcomes of intentional actions. Participants read three-sentence stories that varied the presence of an explicit goal and the semantic association between the outcome and its situational context (i.e., physical or virtual location). The ease of processing…

An overarching motivation driving my research has been to further our theoretical understanding of how readers successfully comprehend challenging text. This article describes the theoretical origins of this research program and my quest to understand comprehension processes through the use of technology. Coh-Metrix was developed to measure, and…

In this study we investigated whether the beneficial effect of adding illustrations to text can be explained by the fact that illustrations facilitate analogous mental representation construction from text in visuospatial working memory. For this the secondary task paradigm was used. It was expected that the secondary task interfered only with…

This study aims to establish whether the processing of different connectives (e.g., "and," "but") and different coherence relations (addition, contrast) can be modulated by a structural feature of the connected segments--namely, parallelism. While "but" is mainly used to contrast two expressions, "and"…

Understanding discourse connectives is an important step to achieving effective verbal communication. Yet, the ability of adult native speakers to understand the broad range of connectives found in most Indo-European languages has seldom been assessed. In this article we demonstrate that some adults have difficulties recognizing correct and…

Authors of fiction need not provide accurate accounts of the world, which might generate concern about the kinds of information people can acquire from narratives. Research has demonstrated that readers liberally encode and rely upon the information provided in fictional stories. To date, materials used to demonstrate these effects have largely…

In this article, I review and discuss the work presented in this special issue while focusing on a number of issues that warrant further investigation in validation research. These issues pertain to the nature of the validation processes, the processes and mechanisms that support validation during comprehension, the factors that influence…

The present study examined the influence of a human or computer "partner" on the production of fillers ("um" and "uh") during a question and answer task. Experiment 1 investigated whether or not responding to a human partner as opposed to a computer partner results in a higher rate of filler production. Participants…

This study addresses the need in discourse psychology for computational techniques that analyze text on multiple levels of cohesion and text difficulty. Discourse psychologists often investigate phenomena related to discourse processing using lengthy texts containing multiple paragraphs, as opposed to single word and sentence stimuli.…
