The Self-Promotion Boost: Positive consequences for observers of high-rank self-promoters
Kelly Nault & Andy Yap
Journal of Personality and Social Psychology, forthcoming
Abstract:
This research examines how self-promotion conducted by relatively higher ranked individuals affects observers’ affect and motivation. We developed and tested the idea of a Self-Promotion Boost -- superior self-promoters inspire lower ranked observers by sharing achievement-related information that reflects opportunities to succeed in relevant domains, eliciting high-activation positive affect and greater motivation. Results from nine experimental studies (total N = 2,599) revealed that (1) interactions involving self-promotion by superiors (vs. peers or subordinates) lead observers to report greater experiences of high-activation positive affect (e.g., hope, inspiration), whereas peers and subordinates (vs. superiors) generate greater high-activation negative affect. (2) The positive effects of superiors’ self-promotion go above and beyond effects elicited by superiors in interactions devoid of self-promotion. (3) Observers’ inferences of self-promoters’ earned success mediate the relationships between self-promoter rank and observer high-activation positive and negative affect. (4) High-activation positive affect elicited by superiors in turn leads to greater observer-reported motivation. Finally, (5) we found support for our theory that these effects are strengthened when observers view the self-promoting superiors as role models: Superiors elicit high-activation positive affect when they (a) are admired and respected by observers, (b) communicate what observers deem to be achievable successes, and (c) share accomplishments relevant to observers’ own domain of success. Our findings illustrate the positive effects self-promotion can have on observers of this behavior, and how this behavior can consequently bolster observer motivation. We discuss implications for the literature on self-promotion, social comparison, and social motivation.
The impact of COVID-19 on a college freshman sample reveals genetic and nongenetic forms of susceptibility and resilience to stress
Cortney Turner et al.
Proceedings of the National Academy of Sciences, 5 December 2023
Abstract:
Using a longitudinal approach, we sought to define the interplay between genetic and nongenetic factors in shaping vulnerability or resilience to COVID-19 pandemic stress, as indexed by the emergence of symptoms of depression and/or anxiety. University of Michigan freshmen were characterized at baseline using multiple psychological instruments. Subjects were genotyped, and a polygenic risk score for depression (MDD-PRS) was calculated. Daily physical activity and sleep were captured. Subjects were sampled at multiple time points throughout the freshman year on clinical rating scales, including GAD-7 and PHQ-9 for anxiety and depression, respectively. Two cohorts (2019 to 2021) were compared to a pre-COVID-19 cohort to assess the impact of the pandemic. Across cohorts, 26 to 40% of freshmen developed symptoms of anxiety or depression (N = 331). Depression symptoms significantly increased in the pandemic years and became more chronic, especially in females. Physical activity was reduced, and sleep was increased by the pandemic, and this correlated with the emergence of mood symptoms. While low MDD-PRS predicted lower risk for depression during a typical freshman year, this genetic advantage vanished during the pandemic. Indeed, females with lower genetic risk accounted for the majority of the pandemic-induced rise in depression. We developed a model that explained approximately half of the variance in follow-up depression scores based on psychological trait and state characteristics at baseline and contributed to resilience in genetically vulnerable subjects. We discuss the concept of multiple types of resilience, and the interplay between genetic, sex, and psychological factors in shaping the affective response to different types of stressors.
Investigating Inattentional Blindness Through the Lens of Fear Chemosignals

Psychological Science, forthcoming
Abstract:
Inattentional blindness is a phenomenon wherein people fail to perceive obvious stimuli within their vision, sometimes leading to dramatic consequences. Research on the effects of fear chemosignals suggests that they facilitate receivers’ sensory acquisition. We aimed to examine the interplay between these phenomena, investigating whether exposure to fear chemosignals (vs. rest body odors) can reduce the inattentional-blindness handicap. Utilizing a virtual-reality aquarium, we asked participants to count how many morsels a school of fish consumed while two unexpected stimuli swam by. We predicted that participants exposed to fear chemosignals (N = 131) would detect unexpected stimuli significantly more often than participants exposed to rest body odors (N = 125). All participants were adult Portuguese university students aged 18 to 40 years. The results confirmed our hypothesis, χ2(1) = 6.10, p = .014, revealing that exposure to fear chemosignals significantly increased the detection of unexpected stimuli by about 10%. The implications of our findings open a novel avenue for reducing the adverse consequences of inattentional blindness.
Pitch as a Recipient, Channel, and Context Factor Affecting Thought Reliance and Persuasion
Joshua Guyer et al.
Personality and Social Psychology Bulletin, forthcoming
Abstract:
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.
The psychophysiology of Mastermind: Characterizing response times and blinking in a high-stakes television game show
Skyler Wyly et al.
Psychophysiology, forthcoming
Abstract:
Television game shows have proven to be a valuable resource for studying human behavior under conditions of high stress and high stakes. However, previous work has focused mostly on choices -- ignoring much of the rich visual information that is available on screen. Here, we take a first step to extracting more of this information by investigating the response times and blinking of contestants in the BBC show Mastermind. In Mastermind, contestants answer rapid-fire quiz questions while a camera slowly zooms in on their faces. By labeling contestants' behavior and blinks from 25 episodes, we asked how accuracy, response times, and blinking varied over the course of the game. For accuracy and response times, we tested whether contestants responded more accurately and more slowly after an error -- exhibiting the “post-error increase in accuracy” and “post-error slowing” which has been repeatedly observed in the lab. For blinking, we tested whether blink rates varied according to the cognitive demands of the game -- decreasing during periods of cognitive load, such as when pondering a response, and increasing at event boundaries in the task, such as the start of a question. In contrast to the lab, evidence for post-error changes in accuracy and response time was weak, with only marginal effects observed. In line with the lab, blinking varied over the course of the game much as we predicted. Overall, our findings demonstrate the potential of extracting dynamic signals from game shows to study the psychophysiology of behavior in the real world.
