Pictures help people to comprehend and remember texts. We report two experiments designed to test among several accounts of this facilitation. Students read texts describing four-step procedures in which the middle steps were described as occurring at the same time, although the verbal description of the steps was sequential. A mental representation of the procedure would have the middle steps equally strongly related to the preceding and succeeding steps (because the middle steps are performed simultaneously), whereas a mental representation of the text would have the middle step that was described first more closely related to the preceding step than ...

Expository hypertexts may contain specific types of signals such as navigable topical overviews and hyperlinks that map conceptual relationships between text contents. Two experiments with German university students (N = 130, 75% female, mean age 25 years) were conducted to test the hypothesis that hypertext-specific signals particularly support learners with badly routinized reading skills in organizing and integrating complex learning materials. The experiments were based on naturalistic texts and essay-writing tasks typical for exam preparation. Learning outcomes were measured by characteristics of participants' essays (amount of knowledge, knowledge focusing, knowledge integration). In both experiments, a hypertext with a high amount ...

Objective: This randomized controlled trial aimed to determine whether an interactive CD-ROM improved cancer patients' recall of chemotherapy treatment information over standard written information, and whether demographic, cognitive, and psychological factors better predicted recall than this format of delivery. Methods: One-hundred- and-one new patients about to commence chemotherapy were randomized to receive written information or a CD-ROM containing treatment information before giving informed consent. Patients' recall, concentration, short-term memory, reading comprehension, anxiety, depression, and coping styles were assessed with standardized measures pre-treatment. Seventy-seven patients completed tests for recall of treatment information before their second chemotherapy session. Results: Intention-to-treat analyses indicated ...

Previous research has demonstrated that judicial instructions on the law are not well understood by jurors tasked with applying the law to the facts of a case. The past research has also shown that jurors are often confused by the instructions used in the sentencing phase of a capital trial. The current research tested the effectiveness of a debunking approach to improving juror misunderstanding associated with capital sentencing instructions. Participants were randomly assigned to hear either Florida's pattern instructions used in the penalty phase of a capital trial or the same instructions with additional statements that mentioned and refuted misconceptions ...

This study explored the effect of text cohesion on reading comprehension of challenging science texts among students with little topic-relevant knowledge. Introductory level psychology students, considered to have a low level of knowledge on the topic, read high and low cohesion versions of biology texts. After reading the texts, their comprehension of the texts was assessed with text-based or inference-based open-ended comprehension questions. The results showed that participants benefited from high cohesion texts. The benefit was observed only for text-based questions, and the positive effect was marginally larger for skilled compared to unskilled readers. This study provides a better understanding ...

Computer-based learning environments include verbal aids helping learners to gain a deep understanding. These aids can be presented in either the visual or the auditory modality. The problem is that it is not clear-cut how to present them for two reasons: the modality principle [Mayer, R.E., 2001. Multimedia Learning. Cambridge University Press, New York] is not applicable because verbal aids do not usually come with related pictures and the little empirical research on the question provides diverging results. Our aim was twofold: to present a research framework, which makes it possible to reinterpret prior findings, and to test it empirically ...

Previous work on learning from text has demonstrated that although illustrated text can enhance comprehension, illustrations can also sometimes lead to poor learning outcomes when they are not relevant to understanding the text. This phenomenon is known as the seductive details effect. The first experiment was designed to test whether the ability to control one's attention, as measured by working memory span tasks, would influence the processing of a scientific text that contained seductive (irrelevant) images, conceptually relevant images, or no illustrations. Understanding was evaluated using both an essay response and an inference verification task. Results indicated that low working ...

This experiment addressed the question of how headings influence readers' memories for text content. College students read and recalled a 12-topic expository text. Half of the participants were trained to construct a mental outline of the text's topic structure as they read and then use their mental outlines to guide their recall attempts. The remaining participants did not receive such training. Half of the participants read a text containing headings before every subsection; the other half read the same text without headings. The results were that participants who received training and/or read the text with headings remembered text topics and ...

Two questions regarding signals' influence on memory were examined. First, the relationship between headings and text was manipulated to determine whether headings serve as visual cues, directing readers to recall all subsequent information, or content-specific cues, directing readers to recall only to certain information. Second, distance between headings and signaled information was manipulated to determine the extent to which headings focus readers' recall. College students read a multiple-topic expository text. Free recall for main topics was facilitated by being related to headings and being close to headings and inhibited by being unrelated to headings and distant from headings. Conditional recall ...
