This study uniquely examined the effects on self, cognition, anxiety, and physiology when iPhone users are unable to answer their iPhone while performing cognitive tasks. A 2 x 2 within-subjects experiment was conducted. Participants (N = 40 iPhone users) completed 2 word search puzzles. Among the key findings from this study were that when iPhone users were unable to answer their ringing iPhone during a word search puzzle, heart rate and blood pressure increased, self-reported feelings of anxiety and unpleasantness increased, and self-reported extended self and cognition decreased. These findings suggest that negative psychological and physiological outcomes are associated with iPhone separation and the inability to answer one's ringing iPhone during cognitive tasks. Implications of these findings are discussed.
Effects of various mass media on political learning during the 1992 presidential campaign are examined via analyses of two voter surveys conducted in different states. Three indicators of political knowledge are compared: differences on issues between parties (Republican vs. Democratic), differences on issues among candidates (Bush vs. Clinton vs. Perot), and personal knowledge about the candidates (Bush, Clinton, and Perot). Campaign media, including both news coverage and special events (conventions, debates), added significantly to the prediction of both kinds of knowledge about the candidates, even after controlling for major demographic variables and for habitual uses of news media. Of the new forms of media campaigning that became prominent in 1992, at least the interview / talk show format apparently added to voter learning about candidates. Television sources of various types tended to contribute more to learning about the candidates, whereas the newspaper was the medium more associated with knowledge of policy differences between the two major parties.
This study experimentally tested the effects of 2 types of content commonly found in anti-tobacco television messages-content focused on communicating a health threat about tobacco use (fear) and content containing disgust-related images-on how viewers processed these messages. In a 2 x 2 within-subjects experiment, participants watched anti-tobacco television ads that varied in the amount of fear and disgust content. The results of this study suggest that both fear and disgust content in anti-tobacco television ads have significant effects on resources allocated to encoding the messages and on recognition memory. Heart-rate data indicated that putting fear- or disgust-related content into anti-tobacco ads led to more resources allocated to encoding compared to messages without either feature. However, participants appeared to allocate fewer resources to encoding during exposure to messages featuring both fear and disgust content. Recognition was most accurate for messages that had either fear or disgust content but was significantly impaired when these 2 message attributes occurred together. The results are discussed in the context of motivated processing and recommendations about message construction are offered to campaign designers.
This study charts pathways through message resistance to enhance the persuasiveness of diabetes self-care messages. A 2 (narrative) × 2 (other-referencing) × 2 (message) × 4 (order) experiment with adult diabetics (N = 58) tested whether packaging overt recommendations as a story rather than an informational argument (i.e., narrative structure) and highlighting the impact of health decisions on family and friends rather than the individual (i.e., other-referencing) can effectively attenuate psychological reactance to messages encouraging healthy diet and physical activity. Narrative and other-referencing each led to lower perceived threat to choice, less state anger and counterarguing, less negative cognitive responses, more positive attitudes toward the ad and the behaviors promoted, and greater intended compliance with message recommendations. Findings illustrate two strategies that communicators may employ in order to benefit from clear, direct health messages while avoiding the reactance they may provoke. Moreover, findings inform message design for diabetes self-care education.
