The negativity bias is a phenomenon that is characterized by infants being more influenced by, attending more to, and responding to more negative emotion information from the environment than positive emotion information. This study used a Tobii© T60 eye-tracking system to examine differences in 8- to 12-month-old infants' latencies to disengage from a centrally-presented face for three different emotion conditions-happy, sad, and fear. The events also varied by motion type-static versus dynamic. Additionally, infants' locomotor experience and parental affect served as two additional measures of experience, and assessed for their contributions to the infants' negativity bias. It was expected that infants would show longer latencies to disengage from the negative emotion events (fear or sad) compared to the positive emotion event (happy), but also that the latencies would be augmented by event type (dynamic > static), locomotion experience (high > low), and parental affect (higher negativity > lower negativity). Although infants showed more attention to dynamic than static emotion displays (especially on the speaker's mouth), and more attention to happy and sad compared to fear displays, no consistent effect of emotion type was found on infants' attention disengagement. Thus, no evidence for a negativity bias was seen. The results are interpreted with respect to possible contributions of the bimodal nature of emotion expression in the current study as well as age-related attentional differences in responding to a wide range of emotion cues. / Master of Science

In this study, I examine the effects of audit guidance and estimation uncertainty on auditors’ confirmation bias and professional skepticism when evaluating fair value estimates. Fair value estimation is becoming more prevalent in financial reporting frameworks, and regulators warn that fair value estimation presents higher risk of material misstatement when greater judgment in estimation is involved. In addition recent evidence from the Public Company Accounting Oversight Board (PCAOB) indicates that some auditors may not be exercising sufficient professional skepticism when performing audit procedures in higher risk areas of the audit. Martin et al. (2006) suggest that it may be the audit standards themselves that orient auditors toward biased evaluation of management’s estimates, suggesting that such directional audit guidance leads to confirmation bias. Further, it is possible that because of auditors’ intolerance for ambiguity, that a greater degree of estimation uncertainty exacerbates the bias. Thus, I examine whether directional audit guidance (e.g., support management’s estimate, and oppose management’s estimate) versus non-directional audit guidance (e.g., develop own estimate) affects auditors’ confirmation bias differentially under varying degrees of uncertainty (e.g., low vs. high), and the extent to which this bias increases or decreases professional skepticism. The results show that auditors exhibit the greatest confirmation bias when they are directed to oppose versus support management’s estimate or generate their own estimate, and that this bias increases the degree of professional skepticism exercised by auditors. Further, the greatest extent of confirmation bias resulted when auditors were directed to oppose management’s estimate and estimation uncertainty was high. This study sheds light on the effects of directional versus non-directional audit guidance in the presence of uncertainty and should be informative to standard setters and practitioners as they press forward in issuing new audit guidance related to the evaluation of fair value estimates.

This dissertation explains how and under what conditions voters are affected by campaign advertising, taking particular account of the conditioning role played by political knowledge and ad tone. It builds on psychological research showing that people make regular mistakes in attribution, evaluation, and decision making; that they tend to give greater weight to negative than to equally credible positive information; that they better match their political choices with their interests and values when they are more politically knowledgeable; and that cognitive shortcuts cannot fully compensate for meager political knowledge. I introduce a psychological theory of how individuals react to campaign advertising in light of: (1) their political knowledge and (2) their natural impulse to give greater weight to negative information (i.e., negativity bias). Using data from an original laboratory experiment conducted in Mexico City in 2012 and from the 2006 Mexico Panel Study, I examine the effect of campaign advertising on the attribution of candidates' character traits, the evaluation of candidates' policy proposals, and vote intentions. I show that campaign advertising's effects on the attribution of candidates' character traits and the evaluation of their policy proposals are conditioned by the voter's degree of political knowledge and the ad's tone (negative or positive). I also show that campaign advertising has a significant, indirect effect on vote intentions through its effect on the attribution of candidates' character traits and the evaluation of their policy proposals. Finally, I explain why negative advertising has systematically bigger effects on voting behavior than equivalent positive advertising. I look at the case of Mexico to shed light on the effects of campaign advertising in developing democracies. Since most academic research has looked at the United States, this thesis intends to deepen our understanding of campaign advertising in comparative perspective, looking at a country where the thinness of party identification, the ambiguity of issue ownership, and the novelty of the party system renders voters more susceptible to information in campaign advertising. / text

In recent years, negativity has become a dominant theme in the political campaign. However, there are no comprehensive studies to measure the amount of negativity and to examine how parties and candidates adopt these negative strategies, particularly in the Canadian context. Although some studies have focused on a particular aspect of negative campaigning in a Canadian election, the question remains of how and to what extent parties adopt negative strategies in an election. In this thesis, I have collected and analyzed parties’ press releases in the 2015 federal election to examine and explain negativity in parties’ political campaigns. I have tested my results according to five primary theories of negative campaigning, including competitive positioning, ideological proximity, party organization, coalition or minority effect, and negative personalization, to see if these theories apply in the Canadian context. My results indicate that the 2015 federal campaign was a highly negative one, and most of the negative attacks have been directed towards the leader of the Conservative Party, Stephen Harper, while the Conservative Party published the least amount of negative attacks during the campaign. I also found that the Liberal Party has published the most negative statements during the campaign. My results also show that one of the influential factors in shaping parties’ negative campaign strategies is the other parties’ status in public opinion polls, particularly the federal voting intention factor. Although the results show that most of the attacks in the 2015 campaign targeted leaders of parties, I did not find enough support in my models to verify the negative personalization theory. The overall findings of this thesis show that Canadian elections are moving toward a presidential-style campaign, similar to the United States, by becoming more negative and more personalized, which can have significant implications for Canadian democracy.

Des sons émotionnels furent présentés comme stimuli cibles lors d'une tâche auditive de type oddball. Les effets acoustiques furent départagés des effets émotionnels à l'aide d'une tâche contrôle similaire utilisant une version brouillée des sons originaux et dépourvue de propriétés émotionnelles. Les résultats du oddball émotionnel qui ont différé du oddball contrôle ont montré des effets de valence inversés dans les composantes électrophysiologiques P2 et P300; la valence négative ayant une amplitude plus grande dans la fenêtre de 130-270ms mais moins intense autour de 290-460ms, lorsque comparée aux valences positives et neutres. Les résultats P2 peuvent être interprétés comme une mobilisation attentionnelle précoce privilégiant les stimuli potentiellement dangereux, tandis que les résultats de la P300 pourrait indiquer une évaluation moins détaillée de ces stimuli. / In an auditory oddball task, negatively (disgust) and positively (laughter) valenced sounds were presented as rare targets. To disentangle acoustic effects from emotional ones, a control oddball was conceived with a non‐emotional scrambled version of the original target sounds as rare targets. Results from the emotional oddball that differed from the control oddball showed an inverse effect of valence in the P2 and P300 range, with negative valence having higher mean amplitude values in the 130‐270ms range, but lower values in the 290‐460 range when compared to ERPs elicited by positive and neutral valence. The P2 results are interpreted as early mobilization of attentional resources towards potentially threatening stimuli, while the P300 results could reflect less detailed evaluation of such stimuli.

Frågeställningar: Hur ser företags processer ut för att skapa innehåll till sociala medier? Hur engagerar sig konsumenter till innehåll som företag publicerat på sociala medier? Syfte: Det huvudsakliga syftet med studien är att beskriva och förklara företags processer för att skapa innehåll till sociala medier och analysera konsumenters engagemang till innehåll som företag publicerat. Studien syftar även till att tillhandahålla en konceptuell figur för hur förloppet att skapa, publicera och följa upp innehåll mellan ett företag och ett konsultbolag ser ut. Det avslutande syftet är att kunna ge rekommendationer till företag om hur de kan utveckla sitt användande av sociala medier som ett marknadsföringsverktyg. Metod: Studien hade en induktiv ansats med ett explorativt syfte. Undersökningen genomfördes med en kvalitativ metod. Data samlades in genom personliga intervjuer och genom en observationsstudie med en kompletterande intervju. En kvalitativ dataanalys utfördes för att analysera insamlad empirisk data. Resultat: Företags processer till att skapa innehåll är otillräcklig och det finns utrymme för förbättring. Det framkom även att konsumenter har ett större engagemang till innehåll som företag publicerat om konsumenternas vänner rekommenderat innehållet, om det är humoristiskt eller har ett välgörande ändamål. Teoretiskt och praktiskt bidrag: Det teoretiska bidraget är att utveckla processen till att skapa innehåll på sociala medier. Praktiska bidrag är i form av rekommendationer till företag angående hur de kan utveckla sitt användande av sociala medier som ett marknadsföringsverktyg. / Research questions: Do companies have processes to create content for social media? How do consumers engage in content that companies have published on social media? Purpose: The main purpose of this study is to describe and explain companies’ processes to create content for social media and analyze the consumers’ commitment to the content that companies have published. Another purpose is to provide a conceptual model for the course of creating, publishing and following up content between a company and a consulting firm. Finally we aim to give recommendations to companies about how they can develop their use of social media as a marketing tool. Method: The study has an inductive approach with an explorative purpose. The survey was performed using a qualitative method. The data was collected by means personal interviews and an observational study with an additional interview. This empirical data was analyzed using a qualitative data analysis. Results: The companies’ processes to create content are insufficient. The study also revealed that consumers have a greater commitment to content published by companies if their friends have recommended the content, if it is humoristic or related to charity. Theoretical and practical contributions: The theoretical contribution is to develop the process to create content on social media. The practical contribution is in the form of recommendations to companies about how they can develop their usage of social media as a marketing tool.

My dissertation aims to contribute to a more comprehensive understanding of how consumers make sense of online word-of-mouth. Each essay in my dissertation probes beyond the effect of rating valence and explores the role of textual content. In the first essay, I explore negativity bias among online consumers evaluating peer information about potential sellers. I propose that both the likelihood of negativity bias and resistance to change after a trust violation will depend on the domain of information discussed in a review. Three experiments showed that negativity bias is more prominent for information regarding sellers' integrity than information regarding their competence. These findings suggest that the universality of negativity bias in a seller review setting has been exaggerated. In the second essay, I examine the impact of emotional arousal on the perceived helpfulness of text reviews. I propose an inverse U-shaped relationship by which the arousal conveyed in a text review will be associated by readers with lower perceived helpfulness only beyond an optimal level, and that the detrimental effect of arousal is present for negative reviews even when objective review content is controlled for. To test these hypotheses, two studies were conducted in the context of Apple's mobile application market. In Study 1, I collected actual review data from Apple's App Store, coded those reviews for arousal using text analysis tools, and examined the non-linear relationship between arousal and review helpfulness. In Study 2, I experimentally manipulated the emotional arousal of reviews at moderate to high levels while holding objective content constant. Results were largely consistent with the hypotheses. This essay reveals the necessity of considering emotional arousal when evaluating review helpfulness, and the results carry important practical implications. In the third essay, I explore effects of the emotions embedded in a seller review on its perceived helpfulness to readers. I propose that over and above the well-known negativity bias, the impact of discrete emotions in a review will vary, and that one source of this variance is perceptions of reviewers' cognitive effort. I focus on the roles of two distinct, negative emotions common to seller reviews: anxiety and anger. In Studies 1 and 2, experimental methods were utilized to identify and explain the differential impact of anxiety and anger in terms of perceived reviewer effort. In Study 3, actual seller reviews from Yahoo! Shopping websites were collected to examine the relationship between emotional review content and helpfulness ratings. These findings demonstrate the importance of discriminating between discrete emotions in online word-of-mouth, and they have important repercussions for consumers and online retailers.
