Salivary cortisol changes in humans after winning or losing a dominance contest depend on implicit power motivationMichelle M Wirth
Department of Psychology, University of Michigan, Ann Arbor, 48109, USA
Horm Behav 49:346-52. 2006..These studies add to the evidence that individual differences greatly influence whether a social stressor like losing a contest activates the HPA axis in humans...- Relationship between salivary cortisol and progesterone levels in humansMichelle M Wirth
University of Michigan, Department of Psychology, Ann Arbor, MI 48109 1043, USA
Biol Psychol 74:104-7. 2007..These findings suggest that progesterone is released from the adrenal along with cortisol in humans, due to general adrenal activation and/or possibly as an additional negative feedback mechanism to down-regulate the stress response... - Effects of affiliation arousal (hope of closeness) and affiliation stress (fear of rejection) on progesterone and cortisolMichelle M Wirth
University of Michigan, Department of Psychology, 530 Church St, Ann Arbor, MI 48109 1043, USA
Horm Behav 50:786-95. 2006..As prior research implicates PROG in down-regulation of stress, we speculate that PROG release during stress may encourage affiliation for stress reduction purposes... - Effects of implicit power motivation on men's and women's implicit learning and testosterone changes after social victory or defeatOliver C Schultheiss
Department of Psychology, University of Michigan, Ann Arbor, MI 48109 1109, USA
J Pers Soc Psychol 88:174-88. 2005..In both men and women, self-reported affective states were influenced only by contest outcome and were unrelated to participants' testosterone changes or implicit learning... 
Social closeness increases salivary progesterone in humansStephanie L Brown
VA Health Services Research and Development Center of Excellence, VA Ann Arbor Healthcare System, Ann Arbor, MI, USA
Horm Behav 56:108-11. 2009..Across conditions, progesterone increase one week later predicted the willingness to sacrifice for the partner. These results are discussed in terms of the links between social contact, stress, and health...- Perceived facial expressions of emotion as motivational incentives: evidence from a differential implicit learning paradigmOliver C Schultheiss
Department of Psychology, University of Michigan, Ann Arbor, MI 48109 1109, USA
Emotion 5:41-54. 2005..For affiliation-motivated individuals, learning was impaired in the context of hostile faces. These findings did not depend on explicit learning of fixed sequences or on awareness of sequence-face contingencies... - Basal testosterone moderates responses to anger faces in humansMichelle M Wirth
University of Michigan, Department of Psychology, 530 Church St, Ann Arbor, MI 48109 1043, USA
Physiol Behav 90:496-505. 2007..These effects were not present for joy faces or for supraliminal anger faces. T may generally decrease aversion to threatening stimuli, and/or may specifically facilitate approach towards signals of dominance challenge... - Exploring the motivational brain: effects of implicit power motivation on brain activation in response to facial expressions of emotionOliver C Schultheiss
Department of Psychology, University of Michigan, Ann Arbor, Michigan, USA
Soc Cogn Affect Neurosci 3:333-43. 2008.... - Effects of affiliation and power motivation arousal on salivary progesterone and testosteroneOliver C Schultheiss
University of Michigan, Ann Arbor, MI 48109, USA
Horm Behav 46:592-9. 2004..These findings suggest that aroused affiliation motivation has a specific stimulatory effect on P, whereas aroused power motivation has a specific stimulatory effect on T in men, but not in women, with high baseline T levels...
