Memory for news in young and old adults

Memory for news stories was studied in 48 young and 48 old adults (20-40 and 60-80 years of age, respectively). Three stories selected from actual news programs were presented in print, audio, and TV formats for study. Young adults recalled a higher proportion of news content than old adults and performed better on source recognition tests. Presentation of the information in a TV format led to better performance than in an audio format for both young and old adults. Hierarchical regression analysis revealed that approximately 86% of the age-related variance in news recall was mediated by measures of sensory acuity and processing speed, and commonality analysis revealed that 75% of the age-related variance was mediated jointly by acuity and speed. Findings support common-cause and generalized slowing views of memory impairment in old age.     

Effects of pre‐trial publicity and jury deliberation on juror bias and source memory errors

We examined the effects of exposure to pre‐trial publicity (PTP) and jury deliberation on juror memory and decision making. Mock jurors either read news articles containing negative PTP or articles unrelated to the trial. They later viewed a videotaped murder trial, after which they either made collaborative group decisions about guilt or individual decisions. Finally, all participants independently attributed specific information as having been presented during the trial or in the news articles. Exposure to PTP significantly affected guilty verdicts, sentence length, perceptions of defendant credibility, and misattributions of PTP as having been presented as trial evidence. Jury deliberation had significant effects on jury verdicts, perceptions of defendant credibility, source memory for trial items, and confidence in source memory judgements, but did not affect sentences or critical source memory errors.

Do central processing and online processing always concur? Analysis of scene order and proportion effects in broadcast news

This study examines the relationship between the central/peripheral processing of the Elaboration Likelihood Model (ELM) and the online/memory‐based processing of impression formation by analyzing the order and proportion effect of scene valence in broadcast news. A 2 (position of positive scenes: beginning and ending) × 3 (proportion of positive scenes: high, medium & low) between design (N = 158) experiment with political campaign broadcast news stories found evidence of central memory‐based processing, which is inconsistent with the common belief that central and online processing always concur. Four typologies of information processing are proposed based on the study's findings: central online processing, peripheral online processing, central memory‐based processing and peripheral memory‐based processing.

How Users Take Advantage of Different Forms of Interactivity on Online News Sites: Clicking,E‐Mailing,and Commenting

This study examines the uptake of multiple interactive features on news sites. It looks at the thematic composition of the most clicked, most e‐mailed, and most commented stories during periods of heightened and routine political activity. Results show that (a) during the former period, the most commented stories were more likely to be focused on political, economic, and international topics (or “public affairs” news) than the most clicked and most e‐mailed articles. (b) The 3 types of interactivity exhibited a greater presence of public affairs content during the period of heightened political activity than during its routine counterpart. (c) As the period of heightened political activity unfolded, consumers' propensity to click on, e‐mail, and comment about public affairs stories increased.     

Repetition and dual coding in procedural multimedia presentations

Students learned toy assembly sequences presented in picture, text, or one of three multimedia formats, and completed order verification, recall, and object assembly tasks. Experiment 1 compared repetitious (i.e. dual format presentations each conveying similar information) with complementary (i.e. dual format presentations each conveying different information) multimedia presentations. Repetitious presentations appear to provide learning benefits as a function of their inherent redundancy; complementary presentations provide benefits as a result of users actively integrating picture and text elements into a cohesive mental model. Experiment 2 compared repetitious with interleaved (i.e. assembly steps presented in alternating picture‐text formats) multimedia presentations. Again, multimedia presentations led to overall learning advantages relative to single‐format presentations, with an emphasis on both repetition and integrative working memory processes. Object assembly performance consistently demonstrated the utility of picture learning, with or without accompanying text. Results are considered relative to classic and contemporary learning theory, and inform educational design. Copyright © 2007 John Wiley & Sons, Ltd.     

Stimulus format and working memory in fast and frugal strategy selection

The necessity of retrieving complex attribute information from long‐term memory has been shown to elevate processing costs and boost the use of simple decision heuristics. This effect was confined to verbal as opposed to pictorial attribute information. In a large‐scale experiment (N = 151), either verbal or pictorial information for inferences had to be retrieved from long‐term memory. Concurrent secondary tasks either interfered with the Central Executive, the Phonological Loop, or the Visuo‐Spatial Sketchpad. These are hypothetical components of working memory responsible for processing different information formats. Whereas the information format massively affected strategy selection, there was an additive rather than interactive effect of secondary task, suggesting enhanced retrieval costs irrespective of the information format. An additional analysis in terms of a similarity match as proposed by exemplar‐based models did not enhance the explanation of the data. Copyright © 2006 John Wiley & Sons, Ltd.     

The Role of Typical and Atypical Events in Story Memory

To understand how viewers or readers process and remember media narratives such as entertainment, news, and information is critical to our understanding of the mental processing of television and other media. Media stories contain both typical and atypical events and people, but little is known about how readers or viewers process and remember these two types of information. Participants in 2 experiments remembered atypical story items much better even a week later. However, the conservative way they treated atypical memories could give the illusion that typical items are better remembered than they really are. The results have implications for both mass media theory and theories of memory.     

The Effects of Scandalous Information on Recall of Policy‐Related Information

Political observers often criticize the news media's focus on scandalous activities of candidates as distracting voters from the “real issues.” However, the extent to which such a fondness for scandal influences voters remains unclear. The present study examines whether exposure to scandalous information about a candidate interferes with memory for policy‐related information. Two possibilities are considered. One possibility is that scandalous information attracts substantial attention and processing from individuals thereby interfering with previously stored campaign information. A second possibility argues that conceiving of memory as organized in associative networks suggests that scandalous information facilitates, rather than interferes with, recall of policy‐related campaign information. Based on data from a longitudinal experiment, I conclude that exposure to scandalous information is less hazardous to voters than is often suggested by political observers.     

Learning procedures: the role of working memory in multimedia learning experiences

The ubiquitous label ‘some assembly required’ signals the appearance of instructions for assembly procedures. These instructions come in various formats, some of which may be more effective than others. Previous research has demonstrated advantages for multimedia as compared to single‐format presentations. The current study sought to outline the cognitive processes contributing to this advantage. Specifically, two experiments examined the working memory and source monitoring processes involved with remembering procedural instructions presented in three different formats. Participants learned procedural instructions while undertaking one of a variety of selective interference tasks targeting working memory subcomponents. Results, while supporting a multimedia advantage for learning, demonstrated selective working memory subsystem involvement with different instruction formats. Further, despite the multimedia advantage, participants often misremembered multimedia presentations as picture‐based ones. These results provide further insight into the cognitive processes that underlie comprehension and memory for multimedia experiences. Copyright © 2006 John Wiley & Sons, Ltd.     

Preschoolers continue to trust a more accurate informant 1 week after exposure to accuracy information

To determine whether children retain a preference for a previously accurate informant only in the short term or for long‐term use, 3‐ and 4‐year‐old children were tested in two experiments. In both experiments, children were given accuracy information about two informants and were subsequently tested for their selective trust in the two informants (Experiment 1: immediately, 1 day and 1 week later; Experiment 2: immediately, 4 days and 1 week later). Both age groups preferred to trust the accurate informant not only immediately after receiving accuracy information but also at subsequent time‐points. Children who were immediately able to explicitly identify the accurate informant were significantly more likely to seek and accept information from her 1 week later. However, even when they had not been asked to explicitly identify the accurate informant both age groups still maintained their preference for her. Thus, by 3 years of age, children spontaneously choose a previously accurate informant up to 1 week after exposure to information regarding her accuracy.     

Mental reinstatement of the misinformation context and the misinformation effect in children and adults

The present study investigated the effects of mental reinstatement of the context in which misleading information about an event was presented on later recognition memory for the event. Five‐year‐olds, 7‐year‐olds and adults were shown a short video depicting a children's adventure and were asked a set of misleading questions to introduce misinformation one week later. Before the recognition memory test was administered another week later, half of the participants were given instructions to mentally reinstate the context of the misleading interview. Memory was assessed with a set of forced‐choice recognition questions once in the misleading interview context and for the children a second time at home one week later. When participants were instructed to mentally reinstate the context of the misleading interview prior to the recognition test, false memory reports occurred more often for adults than for children and had a stronger impact on peripheral information than on central information for both 7‐year‐olds and adults. When 5‐ and 7‐year‐olds were tested at home, false memory reports decreased. Thus, reinstating the context of an interview introducing misinformation can reduce the accuracy of memory reports; the context dependence of both accurate and inaccurate memory reports in children and adults is discussed.

Effects of Popularity-Based News Recommendations (“Most-Viewed”) on Users' Exposure to Online News

This experimental study (N = 107) aims at investigating how the “most-viewed” recommendation features of online news affect users' news story choices, by employing an unobtrusive measurement for news exposure. The major findings clearly support the thesis that the presence of recommendations influences users' selection of news stories. First, the participants' self-reported assessment of the reasons for their story choices indicates that the incorporation of recommendations heightened their awareness of formal salience features. Second, these recommendations decreased the time for website exploration, and therefore increased the time available for reading news articles. Third, when the recommender system was available, approximately 50% of the participants' total story exposures came through the recommendation features. Fourth, those participants who were in the recommendation condition selected a larger number of the most-viewed stories featured in the recommender system than their counterparts in the no-recommendation condition; and a majority (about 80%) of the former group's access to those most-viewed stories was via the recommender system, in terms of either number or time. Last, the mean exposure time per recommended story did not differ across either recommendation conditions (with vs. without) or access routes (recommender system vs. front/topical sections).     

Voting “Against Islamization”? How Anti‐Islamic Right‐Wing,Populist Political Campaign Ads Influence Explicit and Implicit Attitudes Toward Muslims as Well as Voting Preferences

We explore the effects of anti‐Islamic right‐wing, populist political campaign ads on voting intention for a right‐wing populist party using a quota‐based online experiment (N = 174). Additionally, we investigate implicit attitudes (i.e., automatic affective associations) and explicit attitudes (i.e., overtly expressed evaluations) toward Muslims as underlying mechanisms of these effects. We find that exposure to the political campaign ads prompts explicit hostile attitudes toward Muslims mediated by implicit attitudes. Explicit attitudes in turn shape voting intention. Moreover, implicit attitudes toward Muslims predict voting preference beyond the influence of explicit attitudes. Thus, resentments toward Muslims may foster voters’ support for anti‐Islamic right‐wing populist parties even “under the radar” of conscious awareness. In sum, this study demonstrates for the first time the entire process of right‐wing, populist political campaign ads’ effects on voting preferences via implicit and explicit attitudes toward Muslims.     

Visuospatial memory and phonological loop in learning from multimedia

The dual‐task paradigm was used to show how visuospatial working memory and the phonological loop are involved in processing scientific texts and illustrations presented via computer. In experiment 1, two presentation formats were compared: text‐only and text‐with‐illustrations. With a concurrent tapping task, the beneficial effect of illustrations disappeared, while a concurrent articulatory task impaired performance similarly in both presentation formats. An analysis of individual differences revealed that this pattern of results was present in high, but not low spatial span subjects. These results support the selective involvement of visuospatial working memory in processing illustrated texts. In Experiment 2, the text‐only presentation format was compared to an illustrations‐only format. The concurrent articulatory task selectively impaired text‐only processing, compared with processing illustrations‐only. In addition, this pattern of results was found for high, but not low digit span subjects. These results suggest that individual differences define the extent to which the two subsystems of working memory are involved in learning from multimedia. These two subsystems would be mainly involved in the maintenance of a visual trace of illustrations and of a verbatim representation of linguistic information respectively, these representations being the basis for higher‐level comprehension processes.

Memory for time: How people date events

The effect of different formats on the accuracy of dating news and the distribution of personal events was examined in four conditions. In the first, participants had to date events in the absolute time format (e.g., "July 2004"), and in the second, they had to date events in the relative time format (e.g., "3 weeks ago"). In the other conditions, they were asked to choose between the two formats. We found a small backward telescoping effect for recent news events and a large forward telescoping effect for remote events. Events dated in the absolute time format were more accurate than those dated in the relative time format. Furthermore, participants preferred to date news events with the relative time format and personal events with the absolute time format, as well as preferring to date remote events in the relative time format and recent events in the absolute time format.     

Women Are On, But Not In, the News: Gender Roles in Local Television News

This investigation examined 580 news stories in the top three local television news programs in a Northeastern U.S. television market for a two-week period. Content analysis was used to determine whether or not there were gender differences in the prevalence of reporters and anchors and in the type of stories they reported. Analysis of newscasts revealed that female reporters were more likely to present human interest and health related stories, while males were more likely to present political stories. Analysis of news sources revealed that male experts were used significantly more often than were female experts as news sources. There was no relationship between time news stories were presented and gender of the reporters or anchors.     

How Viewers Process Live,Breaking, and Emotional Television News

This study experimentally tested the effects of negative emotional video and presentation style of television news stories on viewers' attention to, and memory for, the stories. News stories were selected that elicited either fear or disgust. Also, stories were presented either as “breaking” news, “live” news, or traditional news. Findings suggest that stories that elicited disgust reduced processing resources available at encoding more than stories that elicited fear, and were recognized less. A signal detection analysis was conducted that indicated higher sensitivity for fear stories than for disgust, but there was a conservative criterion bias shift for disgust stories. Presentation style had little impact on resources available at encoding and recognition memory, except that fewer resources were available at encoding shortly after the story was verbally labeled “live” or “breaking,” but that did not translate into differences in recognition memory. These results suggest that including disgust-eliciting images in television news stories hinders processing. These results also suggest that discrete emotional theory is applicable to the limited capacity model of mediated message processing.     

Effects on Youth of Exposure to Retail Tobacco Advertising1

The absence of significant restrictions on tobacco advertising in stores has prompted concern about the proliferation of these messages and their impact on youth. This is among the first studies to investigate the effects of adolescents’ exposure to retail tobacco advertising. Under the guise of testing teen‐interest news stories, 8th and 9th graders (n= 385) saw photographs of a convenience store that was either dominated by or devoid of tobacco advertising while listening to a story about a proposed tobacco control law or one about teen food purchases. Regardless of the news story they heard, students exposed to the tobacco‐saturated store perceived significantly easier access to cigarettes, believed more peers tried and approved of smoking, and expressed weaker support for tobacco‐control policies than did the comparison group. The study results suggest that widespread tobacco advertising in stores might distort adolescents’ perceptions about the availability, use, and popularity of this product.     

The effect of noun animacy on the processing of unambiguous sentences: Evidence from French relative clauses

It has previously been shown that moving images are remembered better than static ones. In two experiments, we investigated the basis for this dynamic superiority effect. Participants studied scenes presented as a single static image, a sequence of still images, or a moving video clip, and 3 days later completed a recognition test in which familiar and novel scenes were presented in all three formats. We found a marked congruency effect: For a given study format, accuracy was highest when test items were shown in the same format. Neither the dynamic superiority effect nor the study–test congruency effect was affected by encoding (Experiment 1) or retrieval (Experiment 2) manipulations, suggesting that these effects are relatively impervious to strategic control. The results demonstrate that the spatio-temporal properties of complex, realistic scenes are preserved in long-term memory.     

The efficiency of multimedia learning into old age

Background: On the basis of a multimodal model of working memory, cognitive load theory predicts that a multimedia‐based instructional format leads to a better acquisition of complex subject matter than a purely visual instructional format. Aims: This study investigated the extent to which age and instructional format had an impact on training efficiency among both young and old adults. It was hypothesised that studying worked examples that are presented as a narrated animation (multimedia condition) is a more efficient means of complex skill training than studying visually presented worked examples (unimodal condition) and solving conventional problems. Furthermore, it was hypothesised that multimedia‐based worked examples are especially helpful for elderly learners, who have to deal with a general decline of working‐memory resources, because they address both mode‐specific working‐memory stores. Sample: The sample consisted of 60 young (mean age = 15.98 years) and 60 old adults (mean age = 64.48 years). Methods: Participants of both age groups were trained in either a conventional, a unimodal, or a multimedia condition. Subsequently, they had to solve a series of test problems. Dependent variables were perceived cognitive load during the training, performance on the test, and efficiency in terms of the ratio between these two variables. Results: Results showed that for both age groups multimedia‐based worked examples were more efficient than the other training formats in that less cognitive load led to at least an equal performance level. Conclusion: Although no difference in the beneficial effect of multimedia learning was found between the age groups, multimedia‐based instructions seem promising for the elderly.
