Running Head: NEED FOR ACHIEVEMENT & CORTISOL REACTIVITY 1 Need for Achievement Moderates the Effect of Motive-Relevant Challenge on Salivary Cortisol Changes

چکیده
The hypothalamic-pituitary-adrenal (HPA) axis plays a key role in the physiological response to stress, preparing the organism for appropriate action. While some research has examined universally relevant threats, other research has suggested that individual differences may moderate the relationship between stress and cortisol release, such that some individuals exhibit modified reactivity to personally relevant stressors or challenges. In the present study we investigated whether one individual difference—the implicit need for achievement—moderates the effect of motive-relevant challenge on salivary cortisol. Participants’ salivary cortisol and felt affect were measured before and after engagement in an achievement task. In the positiveand no-feedback conditions, individuals high in implicit achievement motivation demonstrated increased cortisol response to the task, whereas in the negative feedback condition, individuals high in implicit achievement motivation demonstrated a dampened cortisol response. Furthermore, changes in cortisol were accompanied by changes in felt affect in the same direction, specifically hedonic tone. These results suggest that the HPA axis also responds to non-social-evaluative challenge in a personality-contingent manner.

متن کاملThe implicit affiliation motive moderates cortisol responses to acute psychosocial stress in high school students.
It has been previously shown that the implicit affiliation motive - the need to establish and maintain friendly relationships with others - leads to chronic health benefits. The underlying assumption for the present research was that the implicit affiliation motive also moderates the salivary cortisol response to acute psychological stress when some aspects of social evaluation and uncontrollab...
متن کاملEffect of Massage on Salivary Cortisol Level in Preterm Neonates
Background: Stress in preterm neonates is associated with morbidity and mortality. Preterm newborns who are in need of special care are at risk of experiencing stress because of separation from the mother, ambient noises, lighting intensity, and medical procedures. Massage is believed to reduce stress through touch stimulation, and the cortisol is one of the indicators of the stress response. T...
متن کاملImplicit need for achievement predicts attenuated cortisol responses to difficult tasks
The present research tested the hypothesis that the implicit need for achievement (n Achievement) predicts attenuated cortisol (C) responses to difficult tasks, because it represents a propensity to view difficulty as a cue to mastery reward. In two studies, n Achievement was assessed through content-coding of imaginative stories and salivary C was assessed both at baseline and post-task. In St...
متن کاملThe implicit Power Motive and Adolescents' Salivary Cortisol Responses to Acute Psychosocial Stress and Exercise in School.
In the present study we examined the moderating effect of the power motive on salivary cortisol responses to acute psychosocial stress and exercise in adolescents. Fifty-seven high school students aged M = 14.8 years participated in the study. The Operant Motive Test was applied to measure the implicit power motive and the Personality Research Form was used to measure the explicit power motive....
