Although it was proposed over a century ago that feedback from facial expressions influence emotional experience, tests of this hypothesis have been equivocal. Here we directly tested this facial feedback hypothesis (FFH) by comparing the impact on self-reported emotional experience of BOTOX injections (which paralyze muscles of facial expression) and a control Restylane injection (which …

Anderson, C., & Kilduff, G. J. (2009). Why do dominant personalities attain influence in face-to-face groups? The competence-signaling effects of trait dominance.
Individuals high in the personality trait dominance consistently attain high levels of influence in groups. Why they do is unclear, however, because most group theories assert that people cannot attain influence simply by behaving assertively and forcefully; rather, they need to possess superior task abilities and leadership skills. In the present research, the authors proposed …
Latané, B. (1981). The psychology of social impact. American Psychologist, 36(4), 343-356.
Proposes a theory of social impact specifying the effect of other persons on an individual. According to the theory, when other people are the source of impact and the individual is the target, impact should be a multiplicative function of the strength, immediacy, and number of other people. Furthermore, impact should take the form of …

Aronson, E., & Mills, J. (1959). The effect of severity of initiation on liking for a group. The Journal of Abnormal and Social Psychology, 59(2), 177-181.
“An experiment was conducted to test the hypothesis that persons who undergo an unpleasant initiation to become members of a group increase their liking for the group; that is, they find the group more attractive than do persons who become members without going through a severe initiation. This hypothesis was derived from Festinger’s theory of …
Grant, A. M., &Hofmann, D. A. (2011). Outsourcing inspiration: The performance effects of ideological messages from leaders and beneficiaries.
Although ideological messages are thought to inspire employee performance, research has shown mixed results. Typically, ideological messages are delivered by leaders, but employees may be suspicious of ulterior motives—leaders may merely be seeking to inspire higher performance. As such, we propose that these messages are often more effective when outsourced to a more neutral third …
Grant, A. M. (2012). Leading with meaning: Beneficiary contact, prosocial impact, and the performance effects of transformational leadership. Academy of Management Journal, 55(2), 458-476.
Although transformational leadership is thought to increase followers’ performance by motivating them to transcend self-interest, rhetoric alone may not be sufficient. I propose that transformational leadership is most effective in motivating followers when they interact with the beneficiaries of their work, which highlights how the vision has meaningful consequences for other people. In a quasi-experimental …
Gervais, M., &Wilson, D. S. (2005). The evolution and functions of laughter and humor: A synthetic approach. The Quarterly review of biology, 80(4), 395-430.
A number of recent hypotheses have attempted to explain the ultimate evolutionary origins of laughter and humor. However, most of these have lacked breadth in their evolutionary frameworks while neglecting the empirical existence of two distinct types of laughter—Duchenne and non‐Duchenne—and the implications of this distinction for the evolution of laughter as a signal. Most …
Havas, D. A., Glenberg, A. M., Gutowski, K. A., Lucarelli, M. J., &Davidson, R. J. (2010). Cosmetic use of botulinum toxin-A affects processing of emotional language.
How does language reliably evoke emotion, as it does when people read a favorite novel or listen to a skilled orator? Recent evidence suggests that comprehension involves a mental simulation of sentence content that calls on the same neural systems used in literal action, perception, and emotion. In this study, we demonstrated that involuntary facial …
Collier, R. (2008). Imagined illnesses can cause real problems for medical students. CMAJ, 178(7), 820.
The first symptom Jessica McPherson noticed was a weakness in her arms. Then her muscles began to twitch. She feared the worst, suspecting it might be amyotrophic lateral sclerosis, a fatal neurological disorder also known as Lou Gehrig disease. But her family doctor provided a much less grim diagnosis: medical school syndrome. The …
Iyengar, S. S., &Lepper, M. R. (2000). When choice is demotivating: Can one desire too much of a good thing?. Journal of personality and social psychology, 79(6), 995-1006.
Current psychological theory and research affirm the positive affective and motivational consequences of having personal choice. These findings have led to the popular notion that the more choice, the better—that the human ability to manage, and the human desire for, choice is unlimited. Findings from 3 experimental studies starkly challenge this implicit assumption that having …
