Effects of Scanning Health News Headlines on Trust in Science: An Emotional Framing Perspective.

Rooted in the emotions-as-frames model (EFM), this research examines how hope, fear, and annoyance are evoked through health news headline scanning, and how these emotions influence perceptions of news and medical science institutions as well as health behavioral intentions. A sample of U.S. adults (N = 327) were assigned to one of four headline framing conditions expected to associate with different emotions (positive future frame-hope; threat frame-fear/anxiety; reversal frame-annoyance; and control-neutral) and then asked about their emotional states, trust in science and news, and health-related behavioral intentions. Overall, health news headlines generated more hope than any other emotion across all conditions, and positive future-framed headlines evoked more hope than other framed headlines. Felt hope, in turn, generated greater trust in news and science, higher expectations of medical breakthroughs and cures, and greater intention to engage in preventative health behaviors. Felt anxiety had marginal positive benefits whereas felt annoyance negatively impacted the outcomes of interest. Notably, felt emotion mediated the headline frame-outcome relationships in the positive future/hope condition. These findings offer some support for the EFM and demonstrate that scanning headlines imbued with specific emotional frames can influence important health-related outcomes through the emotions they evoke. We discuss both the theoretical and practical implication of these findings.

Eye-tracking as a proxy for coherence and complexity of texts.

Reading is a complex cognitive process that involves primary oculomotor function and high-level activities like attention focus and language processing. When we read, our eyes move by primary physiological functions while responding to language-processing demands. In fact, the eyes perform discontinuous twofold movements, namely, successive long jumps (saccades) interposed by small steps (fixations) in which the gaze "scans" confined locations. It is only through the fixations that information is effectively captured for brain processing. Since individuals can express similar as well as entirely different opinions about a given text, it is therefore expected that the form, content and style of a text could induce different eye-movement patterns among people. A question that naturally arises is whether these individuals' behaviours are correlated, so that eye-tracking while reading can be used as a proxy for text subjective properties. Here we perform a set of eye-tracking experiments with a group of individuals reading different types of texts, including children stories, random word generated texts and excerpts from literature work. In parallel, an extensive Internet survey was conducted for categorizing these texts in terms of their complexity and coherence, considering a large number of individuals selected according to different ages, gender and levels of education. The computational analysis of the fixation maps obtained from the gaze trajectories of the subjects for a given text reveals that the average "magnetization" of the fixation configurations correlates strongly with their complexity observed in the survey. Moreover, we perform a thermodynamic analysis using the Maximum-Entropy Model and find that coherent texts were closer to their corresponding "critical points" than non-coherent ones, as computed from the Pairwise Maximum-Entropy method, suggesting that different texts may induce distinct cohesive reading activities.

Is News Surveillance related to Cancer Knowledge in Underserved Adults? Testing Three Versions of the Cognitive Mediation Model.

The cognitive mediation model (CMM) proposes indirect paths to news learning such that news surveillance increases news learning through attention to the news and elaboration about the news. But there is a need for additional research that tests key postulates of the CMM especially for media targeting underserved populations. The present study tested three versions of the CMM to model ethnic newspaper learning within a low-income, Spanish-speaking population (N = 150). The original CMM was not supported by the data as elaboration was not related to knowledge; however, a simplified version of the CMM (surveillance → attention → knowledge) was supported. Moreover, a serial mediation model that included a measure of health maven was supported such that news surveillance was positively related to knowledge through maven-ness and attention.

Saliency-driven system models for cell analysis with deep learning.

BACKGROUND AND OBJECTIVES: Saliency refers to the visual perception quality that makes objects in a scene to stand out from others and attract attention. While computational saliency models can simulate the expert's visual attention, there is little evidence about how these models perform when used to predict the cytopathologist's eye fixations. Saliency models may be the key to instrumenting fast object detection on large Pap smear slides under real noisy conditions, artifacts, and cell occlusions. This paper describes how our computational schemes retrieve regions of interest (ROI) of clinical relevance using visual attention models. We also compare the performance of different computed saliency models as part of cell screening tasks, aiming to design a computer-aided diagnosis systems that supports cytopathologists. METHOD: We record eye fixation maps from cytopathologists at work, and compare with 13 different saliency prediction algorithms, including deep learning. We develop cell-specific convolutional neural networks (CNN) to investigate the impact of bottom-up and top-down factors on saliency prediction from real routine exams. By combining the eye tracking data from pathologists with computed saliency models, we assess algorithms reliability in identifying clinically relevant cells. RESULTS: The proposed cell-specific CNN model outperforms all other saliency prediction methods, particularly regarding the number of false positives. Our algorithm also detects the most clinically relevant cells, which are among the three top salient regions, with accuracy above 98% for all diseases, except carcinoma (87%). Bottom-up methods performed satisfactorily, with saliency maps that enabled ROI detection above 75% for carcinoma and 86% for other pathologies. CONCLUSIONS: ROIs extraction using our saliency prediction methods enabled ranking the most relevant clinical areas within the image, a viable data reduction strategy to guide automatic analyses of Pap smear slides. Top-down factors for saliency prediction on cell images increases the accuracy of the estimated maps while bottom-up algorithms proved to be useful for predicting the cytopathologist's eye fixations depending on parameters, such as the number of false positive and negative. Our contributions are: comparison among 13 state-of-the-art saliency models to cytopathologists' visual attention and deliver a method that the associate the most conspicuous regions to clinically relevant cells.

Ethnic newspapers and low-income Spanish-speaking adults: influence of news consumption and health motivation on cancer prevention behaviors.

OBJECTIVE: Ethnic newspapers have the potential to reach and influence various cultural and ethnic subpopulations traditionally underserved in the United States. The current study sought to explore how ethnic news consumption interacts with health motivation to predict cancer prevention behaviors in a sample of Spanish-speaking adults. DESIGN: Participants (N = 100) completed a survey in Spanish, with items measuring demographics, acculturation, health literacy, health motivation, ethnic newspaper consumption (for two papers: La Viva and La Raza), and cancer prevention behaviors. RESULTS: Results indicated consumption of ethnic newspapers correlated positively to acculturation, and cancer screening utilization. In hierarchical regression analyses, the interaction of consumption of an ethnic newspaper (La Raza) and health motivation predicted two of the six prevention behaviors assessed: avoidance of fatty foods and screening behavior. CONCLUSION: The study provides evidence that consumption of Spanish-language newspapers enhances the likelihood that individuals with high levels of health motivation will engage in healthy behaviors. This finding highlights the utility of utilizing Spanish-language newspapers to reach underserved populations.

Perceived Parental Legitimacy as a Moderator of Parent-Child Communication's Effects on Latina/o Adolescent Substance Use.

Utilizing primary socialization theory (PST) and longitudinal survey data from 381 Latina/o sixth- through eighth-grade students, we hypothesized that four types of parent anti-substance use messages (i.e., parents' own past substance use, religious beliefs, respect for family, and peer resistance) would discourage Latina/o students' substance use, particularly when the students perceived their parents' anti-substance use messages were legitimate. The results supported moderation. For Latina/o students who thought that their parents' anti-substance use messages were legitimate, many of the anti-substance use messages were negatively related to substance use, but the associations were positive or nonsignificant for Latina/o students who thought that their parents' anti-substance use messages were not legitimate. The findings extend past work on PST and anti-substance use parent-child communication, highlighting the importance of perceived legitimacy and message content.

Death narratives and cervical cancer: Impact of character death on narrative processing and HPV vaccination.

OBJECTIVES: Narratives hold promise as an effective public health message strategy for health behavior change, yet research on what types of narratives are most persuasive is still in the formative stage. Narrative persuasion research has identified 2 promising features of such messages that could influence behavior: whether characters live or die, and whether characters encounter key barriers. This study investigated the effects of these 2 narrative message features on young women's HPV vaccination intentions and examined mediating psychological processes of narrative persuasion in the context of cervical cancer messages. METHOD: We manipulated these 2 features in a narrative HPV vaccine intervention targeted to a national sample of U.S. women 18-26 who had not initiated the vaccine (N = 247). Participants were randomized in a 2 × 2 between-subjects experiment. RESULTS: Compared to death narratives, survival narratives increased narrative believability and self-efficacy while lowering perceived barriers to vaccination. As features interacted, survival narratives featuring social barriers led to greater narrative transportation (absorption into the story) than other combinations. Moderated mediation analysis tested 10 theoretically derived mediators; transportation and risk severity mediated the narrative-intention relationship. CONCLUSIONS: Findings provide evidence for key psychological postulates of narrative persuasion theory. Results inform practical application for the construction of effective narrative message content in cervical cancer prevention campaigns for young women. (PsycINFO Database Record
