Positive Reappraisals After An Offense: Event-Related Potentials And Emotional Effects Of Benefit-Finding And Compassion, Justin C. Baker, John K. Williams, Charlotte Vanoyen-Witvliet, Peter C. Hill Aug 2016

Positive Reappraisals After An Offense: Event-Related Potentials And Emotional Effects Of Benefit-Finding And Compassion, Justin C. Baker, John K. Williams, Charlotte Vanoyen-Witvliet, Peter C. Hill

Using a within subjects design, three emotion regulation strategies (compassion‐focused reappraisal, benefit‐focused reappraisal, and offense rumination) were tested for their effects on forgiveness, well‐being, and event‐related potentials (ERPs). Participants (N = 37) recalled a recent interpersonal offense as the context for each emotion regulation strategy. Both decisional and emotional forgiveness increased significantly for the two reappraisal strategies compared to offense rumination. Compassion‐focused reappraisal prompted the greatest increase in both decisional and emotional forgiveness. Furthermore, both reappraisal strategies increased positively oriented well‐being measures (e.g., joy, gratitude) compared to offense rumination, with compassion‐focused reappraisal demonstrating the largest effect on empathy. Late positive …

The Contribution Of The Pineal Gland On Daily Rhythms And Masking In Diurnal Grass Rats, Arvicanthis Niloticus, Dorela D. Shuboni, Amna A. Agha, Thomas K. H. Groves, Andrew J. Gall Jul 2016

Melatonin is a hormone rhythmically secreted at night by the pineal gland in vertebrates. In diurnal mammals, melatonin is present during the inactive phase of the rest/activity cycle, and in primates it directly facilitates sleep and decreases body temperature. However, the role of the pineal gland for the promotion of sleep at night has not yet been studied in non-primate diurnal mammalian species. Here, the authors directly examined the hypothesis that the pineal gland contributes to diurnality in Nile grass rats by decreasing activity and increasing sleep at night, and that this could occur via effects on circadian mechanisms or …

Self-Forgiveness And Forgiveness-Seeking In Response To Rumination: Cardiac And Emotional Responses Of Transgressors, Sérgio P. Da Silva, Charlotte Vanoyen-Witvliet, Blake Riek May 2016

Self-Forgiveness And Forgiveness-Seeking In Response To Rumination: Cardiac And Emotional Responses Of Transgressors, Sérgio P. Da Silva, Charlotte Vanoyen-Witvliet, Blake Riek

Self-forgiveness and forgiveness-seeking are important and understudied aspects of forgiveness. We examined the cardiac and emotional patterns of healthy young adults (40 women, 40 men) who recalled an unresolved offense they had caused another person. Participants engaged in four imagery conditions: ruminating about the offense, being humbly repentant and engaging in self-forgiveness, seeking forgiveness from the victim and receiving forgiveness, and seeking forgiveness from the victim and being begrudged. Being repentant and begrudged forgiveness by one’s victim was associated with the same level of guilt as when ruminating, but significantly more negative emotion, less control, and less empathy than when …

Suprachiasmatic Nucleus And Subparaventricular Zone Lesions Disrupt Circadian Rhythmicity But Not Light-Induced Masking Behavior In Nile Grass Rats, Andrew J. Gall, Dorela D. Shuboni, Lily Yan, Antonio A. Nunez, Laura Smale Apr 2016

Suprachiasmatic Nucleus And Subparaventricular Zone Lesions Disrupt Circadian Rhythmicity But Not Light-Induced Masking Behavior In Nile Grass Rats, Andrew J. Gall, Dorela D. Shuboni, Lily Yan, Antonio A. Nunez, Laura Smale

The ventral subparaventricular zone (vSPVZ) receives direct retinal input and influences the daily patterning of activity in rodents, making it a likely candidate for the mediation of acute behavioral responses to light (i.e., masking). We performed chemical lesions aimed at the vSPVZ of diurnal grass rats (Arvicanthis niloticus) using N-methyl-D,L-aspartic acid (NMA), a glutamate agonist. Following NMA lesions, we placed grass rats in various lighting conditions (e.g., 12:12 light-dark, constant dark, constant light); presented a series of light pulses at circadian times (CT) 6, 14, 18, and 22; and placed them in a 7-h ultradian cycle to assess behavioral masking. …

Religious-Body Affirmations Protect Body Esteem For Women Who Base Self-Worth On Appearance Or Others’ Approval, Mary Inman, Anna Snyder, Kelvin Peprah Mar 2016

Religious-Body Affirmations Protect Body Esteem For Women Who Base Self-Worth On Appearance Or Others’ Approval, Mary Inman, Anna Snyder, Kelvin Peprah

Faculty Publications

Women who base their self-worth on appearance or others’ approval are especially vulnerable to low body esteem when they view media images of thin models. We explored one way religion might mitigate the harmful media effects in these women. We tested whether basing self-worth on appearance or others’ approval was positively related to body comparisons and body surveillance. We tested whether reading religious body-affirming statements enhanced feelings of being loved, which would increase body esteem in women who base self-worth on appearance or others’ approval. This experiment manipulated the type of body-affirming statements (religious, spiritual, control) and assessed women’s body …
