Mind-Body Practices and Self-Enhancement: Direct Replications of Gebauer et al.'s (2018) Experiments 1 and 2.

Mind-body practices such as yoga and meditation are often believed to instill a "quiet ego," entailing less self-enhancement. In two experiments, however, Gebauer et al. (2018) demonstrated that mind-body practices may actually increase self-enhancement, particularly because such practices become self-central bases for self-esteem. We conducted preregistered replications of both of Gebauer et al.'s experiments. Experiment 1 was a field study of Canadian yoga students (N = 97), and Experiment 2 was a multiwave meditation intervention among Canadian university students (N = 300). Our results supported Gebauer et al.'s original conclusions that mind-body practices increase self-enhancement. Although the self-centrality effects were not clearly replicated in either experiment, we found evidence that measurement and sampling differences may explain this discrepancy. Moreover, an integrative data analysis of the original and the replication data strongly supported all of Gebauer et al.'s conclusions. In short, we provide new evidence against the ego-quieting perspective and in support of the self-centrality interpretation of mind-body practices.

Naïve beliefs shape emotional reactions to evaluative feedback.

People are motivated to acquire self-evaluative information that favours themselves (self-enhancement) or information that confirms their present self-views (self-consistency). We proposed that participants' naïve theories characterising self-esteem as important may moderate their self-enhancement motivations. Across three samples, we demonstrated that increasing self-esteem importance causes prevention-based emotional reactions to become increasingly dependent on the favorability of feedback. We thus infer that self-enhancement motivation increases when people hold favourable beliefs about the importance of maximising self-esteem. We also replicated past findings in which people regard positive (versus negative) self-relevant information as more valid when they have high (versus low) self-esteem, revealing self-consistency. Individual differences in self-esteem importance and trait self-esteem thus play distinct roles in shaping people's enhancement and consistency motivations.

Falling Vocal Intonation Signals Speaker Confidence and Conditionally Boosts Persuasion.

People are often advised to project confidence with their bodies and voices to convince others. Prior research has focused on the high and low thinking processes through which vocal confidence signals (e.g., fast speed, falling intonation, low pitch) can influence attitude change. In contrast, this research examines how the vocal confidence of speakers operates under more moderate elaboration levels, revealing that falling intonation only benefits persuasion under certain circumstances. In three experiments, we show that falling (vs. rising) vocal intonation at the ends of sentences can signal speaker confidence. Under moderate elaboration conditions, falling (vs. rising) vocal intonation increased message processing, bolstering the benefit of strong over weak messages, increasing the proportion of message-relevant thoughts, and increasing thought-attitude correspondence. In sum, the present work examined an unstudied role of vocal confidence in guiding persuasion, revealing new processes by which vocal signals increase or fail to increase persuasion.

Connecting Attitude Position and Function: The Role of Self-Esteem.

Attitude position and function often are discussed as though they are distinct aspects of attitudes, but scholars have become increasingly interested in how they may interface. We extend existing work showing that people view their positive attitudes as more self-defining than their negative attitudes (i.e., the positivity effect). All datasets support that the positivity effect emerged most strongly among high self-esteem individuals and was attenuated, eliminated, or even reversed among low self-esteem individuals. Furthermore, Study 4 uses a broad array of individual difference measures to triangulate that the higher self-enhancement motivation associated with high self-esteem, rather than merely the positive self-worth of high self-esteem people, is responsible for moderating the positivity effect. In sum, the present work establishes boundary conditions for an important phenomenon in the attitudes literature, develops understanding of the far-ranging implications of trait self-esteem, and illuminates the psychological motivations that connect attitude position and function.

Pitch as a Recipient, Channel, and Context Factor Affecting Thought Reliance and Persuasion.

Three experiments tested how low versus high pitch generated from sources beyond a message communicator can affect reliance on thoughts and influence recipients' attitudes. First, participants wrote positive or negative thoughts about an exam proposal (Experiments 1, 2) or their academic abilities (Experiment 3). Then, pitch from the message recipient (Experiment 1), channel (Experiment 2), or context (Experiment 3) was manipulated to be high or low. Experiment 1 showed that when participants vocally expressed their thoughts using low (vs. high) pitch, thoughts had a greater effect on attitudes toward exams. Experiment 2 revealed low (vs. high) pitch sounds from the keyboard participants used to write their thoughts produced the same effect on thought usage. Experiment 3 demonstrated that thoughts influenced attitudes more when listed while background music was low (vs. high) Pitch can influence attitudes through a meta-cognitive thought reliance process whether emerging from the recipient, channel, or context.

Facilitating Scientific Communication Between Strangers: A Preregistered Lost E-Mail Experiment.

Communication scholars are increasingly concerned about biases that shape people's interactions with science. Past study has focused on echo chambers (cultivating social networks that reinforce existing worldviews). People's facilitation of scientific discourse between strangers also may be shaped by their attitudes. To study the latter, we employed a recent adaptation of Milgram's lost letter technique called the lost e-mail technique (LET). We conducted a preregistered field study using a large undergraduate university sample (N = 1,508) to examine how the LET might elucidate people's treatment of scientific information. We distributed four ostensibly misaddressed scientific messages and monitored the likelihood of these e-mails being facilitated by participants. Participants' beliefs about self-esteem's importance, assessed months earlier, were associated with increased facilitation of scientific claims congruent with (vs. incongruent with) these beliefs. Thus, people shape the spread of online information in a manner matching their beliefs, even for people outside their social networks.

Extraversion as a Moderator of the Efficacy of Self-Esteem Maintenance Strategies.

Four experiments explored how extraversion's connection with self-esteem may depend on specific self-enhancement strategies. Participants' self-esteem threatening feedback indicating that they had performed poorly on a vocabulary or emotional intelligence test. In Experiment 1, participants (N = 80) were randomly assigned to either a control condition (no self-enhancement) or a downward social comparison condition. The procedures for Experiments 2 (N = 470) and 3 (N = 514) were similar, adding a self-serving attribution condition (Experiments 2 and 3) and Basking-in-Reflected-Glory (BIRG) condition (Experiment 3). Across the experiments, extraversion was more related to self-esteem under downward social comparison versus other conditions. BIRGing produced higher self-esteem in Experiment 3 across extraversion levels. Experiment 4 (N = 355) focused on downward social comparison versus control, and provided evidence that an increased perception of being similar to the comparison targets may partially explain extraversion's self-esteem link. Theoretical implications concerning both extraversion and self-enhancement are discussed.

Paralinguistic Features Communicated through Voice can Affect Appraisals of Confidence and Evaluative Judgments.

This article unpacks the basic mechanisms by which paralinguistic features communicated through the voice can affect evaluative judgments and persuasion. Special emphasis is placed on exploring the rapidly emerging literature on vocal features linked to appraisals of confidence (e.g., vocal pitch, intonation, speech rate, loudness, etc.), and their subsequent impact on information processing and meta-cognitive processes of attitude change. The main goal of this review is to advance understanding of the different psychological processes by which paralinguistic markers of confidence can affect attitude change, specifying the conditions under which they are more likely to operate. In sum, we highlight the importance of considering basic mechanisms of attitude change to predict when and why appraisals of paralinguistic markers of confidence can lead to more or less persuasion.

Speech Rate, Intonation, and Pitch: Investigating the Bias and Cue Effects of Vocal Confidence on Persuasion.

Three experiments were designed to investigate the effects and psychological mechanisms of three vocal qualities on persuasion. Experiment 1 (N = 394) employed a 2 (elaboration: high vs. low) × 2 (vocal speed: fast vs. slow) × 2 (vocal intonation: falling vs. rising) between-participants factorial design. As predicted, vocal speed and vocal intonation influenced global perceptions of speaker confidence. Under high-elaboration, vocal confidence biased thought-favorability, which influenced attitudes. Under low-elaboration, vocal confidence directly influenced attitudes as a peripheral cue. Experiments 2 (N = 412) and 3 (N = 397) conceptually replicated the bias and cue effects in Experiment 1, using a 2 (elaboration: high vs. low) × 2 (vocal pitch: raised vs. lowered) between-participants factorial design. Vocal pitch influenced perceptions of speaker confidence as predicted. These studies demonstrate that changes in three vocal properties influence global perceptions of speaker confidence, influencing attitudes via different mediating processes moderated by amount of thought. Evaluation of alternative mediators in Experiments 2 and 3 failed to support these alternatives to global perceptions of speaker confidence.
