The effect of language emotionality on recall : a preliminary study

Czimskey, Natalie Marie 08 July 2011 (has links)
Ten male and 10 female participants were presented with six narrative paragraphs and six 10 word lists. Three of the paragraphs were emotional and three were neutral. Each of the paragraphs contained 20 information units and each word list included five neutral and five emotional words. Immediately following paragraph or word list presentation, the participants were asked to recall the stimuli. The mean percent of emotional units (i.e. units of information recalled from emotional paragraphs) recalled was significantly greater than the mean percent of neutral units recalled. Similarly, the mean percent emotional words recalled from word lists was significantly greater than the mean percent neutral words recalled from word lists. Percent recall was significantly greater for words than for paragraphs for both emotional and neutral stimuli. Results supported the hypothesis that emotional saliency increases verbal recall. / text

Interpersonal Immune and Emotion Dynamics in Couples

Reed, Rebecca Ginny January 2015 (has links)
Social relationships affect a range of health outcomes, including even mortality risk. However, important questions remain concerning the precise mechanisms through which close relationships exert their influence. The present research focuses specifically on immunological and interpersonal emotion processes that may link social relationships and health. The specific aims of this study were to: (1) determine: a) how long it takes for adults' inflammatory levels to recover after an interpersonal laboratory stressor, and b) whether there are associations between allostatic load indicators of cardiovascular functioning and lipid/fat metabolism and immune recovery; (2) determine whether partners' immune patterns are linked, above and beyond the expected diurnal rhythm; and (3) examine the moderating effects of interpersonal emotion regulation patterns on partners' immune functioning. A final goal of the present study was to test the feasibility of conducting such a study in a naturalistic setting with multiple ambulatory immune measures per day, across multiple days. Twenty-four committed heterosexual couples collected their own salivary immune samples 4 times each day (upon waking, mid-morning, later afternoon, and before bed) for 5 consecutive days, including 2 days before a laboratory dyadic stressor (discussing an area of disagreement in the relationship), the day of, and 2 days after, to capture normative baseline diurnal variability and immune recovery post-stressor. Four additional saliva samples were collected on the lab stressor day at baseline, immediately after the disagreement conversation, 30-min. post-conversation, and 90-min. post conversation, for a total of 8 samples collected on the lab stressor day. Salivary samples were assayed for interleukin(IL)-6 using ELISAs (Salimetrics, LLC). As predicted, after the interpersonal laboratory stressor, immune recovery occurred within 48 hours of the stressor, and in fact recovered as early as the evening of the stressor. However, on the day of the lab stressor, IL-6 levels appeared to still be elevated at the later afternoon time point, approximately 3 hours after the stressor had ended. Contrary to my hypothesis, allostatic load indicators of cardiovascular functioning and lipid/fat metabolism did not moderate immune recovery. Secondly, as expected, partners displayed physiological (immune) linkage; specifically, couples showed "anti-phase" physiological linkage on the day of the lab stressor, and "in-phase" linkage on all other days, pooled together, suggesting that couples may have engaged in more of a regulatory effort on the day of the lab stressor, whereas on all other days, there was a relaxation of regulation and enhanced emotional connection. Third, couples' interpersonal emotion dynamics moderated the diurnal pattern of IL-6 such that couples who exhibited disconnected negative emotions, disconnected positive emotions, and displayed indeterminate patterns in their positive emotions, showed dysregulated diurnal IL-6 slopes. Lastly, the methodology of the present study proved to be feasible, and the study was accomplished without unforeseen problems. Ultimately, studying these immune and emotion processes as they occur in every-day life may help to uncover patterns in couples' biology and emotions that may accumulate over time to set people on different health trajectories.

Disambiguating the Roles of Select Medial Prefrontal Subregions in Conscious and Unconscious Emotional Processing

Smith, Ryan Scott January 2015 (has links)
A substantial body of previous research suggests that the medial prefrontal cortex (MPFC) plays an important role in multiple aspects of emotion. These aspects include, but are not limited to, (1) generating, (2) experiencing, and (3) regulating one's own emotional state, as well as (4) facilitating the use of emotion-related information within goal-directed cognition and action selection. However, there is considerable controversy with regard to the distinct functional roles of various MPFC subregions. In this dissertation, I first provide a review of the theoretical and experimental literature to date in order to defend a plausible model of the hierarchical neural processes associated with each of the aspects of emotion highlighted above. This model proposes that different MPFC subregions each play distinct, but interactive, roles at or near the top of the respective hierarchical systems associated with those aspects of emotion. After reviewing this model, I then provide a description of four experiments that test the predictions of this model's claims regarding the roles of three distinct MPFC subregions: the rostral anterior cingulate cortex (rACC), the dorsomedial prefrontal cortex (DMPFC), and the ventromedial prefrontal cortex (VMPFC). These experiments provide independent support for the claims that (1) rACC plays an important role in representing the conceptual meaning of one's felt emotional reactions, (2) DMPFC plays an important role in maintaining representations of one's own emotions within a consciously accessible state, and (3) VMPFC plays an important role in both appraising the emotional significance of one's current situation and triggering the somatic/visceral reactions associated with the generation of an emotional response. In the concluding section of the dissertation, I then integrate these findings together with the larger model and discuss important directions for future research as well as ways in which the model might be extended to include insights from recent advances in theoretical neuroscience associated with predictive coding.

The Geopolitics Of Daily Life In Mostar, Bosnia And Herzegovina

Laketa, Sunčana January 2015 (has links)
Nearly twenty years after the brutal conflict that occurred in Bosnia and Herzegovina (BiH), ethnosectarian ideology continues to permeate all structures and institutions of Bosnian society, from political and educational institutions to religious and cultural ones; most of all, it is significantly embodied in the everyday life of people in Bosnia. It is these everyday practices that I investigate in order to unravel how ethnicity is (re)produced, performed and experienced through mundane practices of moving through space. Specifically, this dissertation asks: What socio-spatial practices and emotional experiences are involved in the processes of solidifying, as well as dissolving, ethnic identity in BiH? The study is a primarily qualitative investigation of daily life, based on deployment of multiple methods such as participant observation, interviews and a photography project. The site of the study is the town of Mostar in southwestern BiH. It has been formally and informally divided between "Croat/Catholic" west Mostar and "Bosniak/Muslim" east Mostar for over 15 years. The findings point to the ways identity and space emerge as performative effects of practice, as well as how different processes of bordering (between "us" and "them"; between "our" and "their" side) are materialized through different affective intensities.

The Effects of Changes in Sleep Schedule Variability on First-Year College Students

Blank, Yelena January 2015 (has links)
College students are known for having poor sleep and irregular sleep schedules, especially during the first year of college. These sleep habits may contribute to poor academic outcomes down the line, as well as increased risk of developing depression and other disorders. The current study aims to look at the degree of change in sleep variability between high school and college and examine its relationship with mood, emotion regulation, and academic performance. The study also aims to explore the relationship between morningness-eveningness tendencies and academic performance, emotion regulation, and sleep variability, reported both at baseline (as perceived by the students) and over 7 days of daily sleep diaries. Additionally, the study is designed to look at day-to-day effects of sleep on mood. Data were obtained from 311 college freshmen (237 females). Participants were 17-19 years old (M=18.4) and freshmen in college. The study took place over one baseline internet-based session and a week of internet-based daily questionnaires. While students had significantly more variable schedules in college than in high school, this change did not correlate with or predict any measures of interest, including sleep quality, grades, and mood. However, overall variability, as well as eveningness, was associated with a number of negative outcomes, including lower GPA, less adaptive emotion regulation strategies, worse mood, and more depression symptoms.

Eating to Regulate Emotion in the Context of Long-Term Relationships

Skoyen, Jane A. January 2013 (has links)
Most people have difficulty maintaining a healthy diet. Both social and individual factors play a role in shaping one's diet, and individual factors might be differentially associated with eating depending on social conditions. The present research focuses on eating to regulate emotion and body weight in the context of couple relationships. Forty-three committed heterosexual couples reported on emotion-regulation strategies including the use of eating to regulate emotion (ERE). During a lab visit, participants discussed their health habits with their partners and their body composition was measured (e.g.: weight, height, percent body fat). Finally, participants completed daily diaries assessing their emotions as well as their food intake relative to their own normal eating. I first tested whether ERE was associated with other measures of emotion regulation as well as body composition at an individual level. As predicted, ERE demonstrated internal consistency, was moderately correlated with an established measure of emotion-eating, and uncorrelated with other measures of emotion regulation. High ERE was associated with higher body mass index, as well as higher waist circumference and percent body fat among older women, and with higher percent body fat among younger men. Secondly, I tested whether self-reported ERE predicted connections between daily emotional fluctuations and eating. Consistent with my hypothesis, those who reported high ERE ate worse when they experienced negative emotions or did not eat better when they experienced positive ones (which was the case among people with low ERE). Finally, I tested whether ERE in couples was associated with body composition under specific relationship conditions. As predicted, when both partners had high ERE, women who used more we-talk during a discussion of health habits also had higher BMI. However, women who used high I-talk in such couples had lower BMI despite having high ERE. Moreover, in such couples expression of negative emotion by partners was associated with higher BMI. Identifying individual and couple-level factors shaping dietary practices adds to development of interventions for poor health habits. It is an important step in shifting disease-focused models of medical care towards more comprehensive, patient-centered care.

The role of positive emotion eliciting activities at promoting physiological recovery from sadness

Soenke, Melissa January 2014 (has links)
The current study investigated whether positive emotion eliciting activities facilitate the physiological, as well as subjective emotional, recovery from feelings of sadness and grief. Results indicated that participants who read a funny or neutral article after writing about the death of someone close had greater decreases in sadness and increases in positive emotion than participants who read an article about coping with grief. The funny and neutral articles were also associated with greater decreases in corrugator supercilii muscle activity. Positive emotion eliciting activities had no effect on zygomaticus major and orbicularis oculi muscle activity, heart rate, or respiratory sinus arrhythmia.

The Role of the Monkey Amygdala in the Autonomic Expression of Emotion

Spitler, Kevin M. January 2007 (has links)
The skin conductance response is involved in the preparation for and response to stimuli with emotional significance. The neural mechanisms responsible for the generation of the skin conductance response are not well understood despite the common use of this signal as an index of emotional response. Data from anatomical, lesion, and neuroimaging studies in humans suggest that the amygdala, a component of the brain circuit for emotion, plays a critical role in the generation of the skin conductance response. Here we employ a novel combination of existing techniques to understand the stimuli that elicit skin conductance responses in the monkey and the neural mechanisms in the amygdala that participate in its generation. We recorded skin conductance responses in monkeys trained to perform a passive image viewing task. This paradigm is a staple of human emotion research but to date has not been adapted to the monkey. In addition, skin conductance responses to these stimuli were recorded in conjunction with single unit responses from the amygdala. This study addresses the relationship between the activity of single neurons recorded from identified nuclei of the monkey amygdala and autonomic responses. Neurons in multiple nuclei of the amygdala showed reliable changes in neuronal discharge prior to the skin conductance response. These neurons were primarily in the dorsal nuclei of the amygdala, which confirms predictions made from anatomical and neuroimaging data. It is suggested that these changes in neuronal discharge may correspond to the generation of this autonomic component of the expression of emotion.

The impact of a noise stressor on capsaicin-induced primary and secondary hyperalgesia

Grimes, Jeffrey Scott 30 September 2004 (has links)
In searching for new human pain models that more closely resemble clinical pain states, the capsaicin pain model has emerged as a viable model for both inflammatory and neuropathic pain states. A principal benefit of the capsaicin model is that it allows study of two different pain processes, primary and secondary hyperalgesia. Primary hyperalgesia is characterized by spontaneous pain and both heat and mechanical hyperalgesia. In addition, it is likely the result of activation and sensitization of both peripheral and central nociceptors. In contrast, secondary hyperalgesia is characterized by only mechanical hyperalgesia and is caused by the sensitization of central nociceptive neurons. Previous research utilizing the capsaicin pain model has primarily focused on the neural properties with little focus on the impact of affective states on capsaicin-related pain processes. The present study examined the impact of a noise stressor on both primary and secondary hyperalgesia. Results indicated that the effects of the noise stressor impacted secondary hyperalgesia, but not primary hyperalgesia.

Regulating the anterior medial prefrontal cortex : exploratory investigation of real-time fMRI training

Smith, Rachelle Marie 11 1900 (has links)
The feasibility of using real-time functional magnetic resonance imaging (fMRI) feedback regarding the level of activation in rostromedial prefrontal cortex (rMPFC) to learn improved regulation of this brain area was examined in a group of 5 young adults. Subjects received real-time feedback from the target brain region while engaging in a blocked-design task involving alternating blocks of attempted up-regulation and down-regulation of the target brain region. A transient negative emotional state was induced prior to each scanning session. Subjects completed 6 scanning sessions (a pre-training session, 4 feedback sessions and a post-training session - no feedback was provided for pre and post-training sessions). The guideline strategy provided to subjects of engaging in emotional awareness during up-regulation and bodily awareness during down-regulation was found to consistently regulate the region in the pre-training session prior to the fMRI feedback sessions. This finding is in line with the previously proposed role of the rMPFC in emotional awareness. In contrast to previous real-time fMRI findings, greater recruitment of the region was observed in the pre-training session compared to the post-training session, with a non-significant negative trend observed across feedback sessions. These results suggest that there may be limitations to which the feedback techniques successfully employed for other brain regions extend to yet unexplored brain regions.
