Experimental research reliably demonstrates that self-regulatory deficits are a consequence of prior effort. However, in naturalistic settings, although people know they sometimes vulnerable to saying, eating, or doing the wrong thing, cannot accurately gauge their capacity self-regulate at any given time. Because self-regulation and autonomic regulation colocalize brain, an measure, heart rate variability (HRV), could provide index strength activity. During experimental manipulation (eating...
This study explored prospectively the effects of dispositional and situational optimism on mood (N = 90) immune changes 50) among law students in their first semester study. Optimism was associated with better mood, higher numbers helper T cells, natural killer cell cytotoxicity. Avoidance coping partially accounted for relationship between mood. Among parameters, optimism—helper relationship, perceived stress optimism-cytotoxicity relationship. Individual differences expectancies,...
Although repetitive thought (RT) styles such as worry, rumination, and processing correlate positively, they have divergent effects on well-being, suggesting important dimensional variation. In Study 1, multidimensional scaling identified 2 dimensions--positive versus negative content valence searching solving purpose--among students (N=978) who completed standard RT measures. 2, (N=100) sorted 25 descriptions of RT. Multidimensional 4 dimensions, including purpose. Content associated with...
Abstract Introduction : The experience of cancer can be understood as a psychosocial transition, producing both positive and negative outcomes. Cognitive processing may facilitate psychological adjustment. Methods Fifty‐five post‐treatment, colorectal survivors ( M =65.9 years old; SD=12.7), an average 13 months post‐diagnosis, were recruited from state registry completed baseline 3‐month questionnaires assessing dispositional (social desirability), cognitive (cognitive intrusions,...
Optimism, or positive outcome expectancy, correlates with better psychological and physiological adjustment, in part because of conscious behavior such as coping. However, procedural, automatic, unconscious processes also may affect adjustment. The emotional Stroop task was used to assess the relationships between optimism attentional bias for positively valenced, negatively neutral current concern, control stimuli. Undergraduate students (n = 48) completed personality measures at beginning...
Although higher education has been linked to better income, longer life expectancy, and health, about 25–45% of incoming college freshmen never graduate. The current study examined whether optimistic expectancies are associated with retention. Participants ( N = 2,189) were given surveys when entering college, academic records attained after freshman year completion. Dispositional optimism less chance dropping out as well motivation adjustment. Academic was also grade point average (GPA)....
Past research has established a connection between regret (negative emotions connected to cognitions about how past actions might have achieved better outcomes) and both depression anxiety. In the present research, relations regret, repetitive thought, depression, anxiety were examined in nationally representative telephone survey. Although thought associated with general distress, only was anhedonic anxious arousal. Further, interaction (i.e., regret) highly predictive of distress but not...
Self-regulation requires overriding a dominant response and leads to temporary self-regulatory fatigue. Existing theories of the nature causes fatigue highlight physiological substrates such as glucose, or psychological processes motivation, but these explanations are incomplete on their own. Historically, physical demonstrate similar pattern useful explanations, recent views emphasize roles both factors. In addition accounting for multiple inputs, newer also explain how can occur even in...
Optimistic expectancies affect many psychosocial outcomes and may also predict immune system changes health, but the nature mechanisms of any such physiological effects have not been identified. The present study related law-school to cell-mediated immunity (CMI), examining within- between-person components this relationship affective mediators. First-year law students ( N = 124) completed questionnaire measures received delayed-type hypersensitivity skin tests at five time points. A...
The concept of stress has a long and perhaps foundational history in health psychology. However, it is also not without its detractors, who point out imprecise simplistic use the concept. Four challenges for research psychology delineate nuanced contextualised future. First, 'stress' can be located environment, appraisal or response (e.g., emotions physiology). Careful conceptualisation assessment differentiate among these locales, as well reveal interactions them. Second, coping refers to...
Using a high-throughput mitochondrial phenotyping platform to quantify multiple features among molecularly defined immune cell subtypes, we the natural variation in DNA copy number (mtDNAcn), citrate synthase, and respiratory chain enzymatic activities human neutrophils, monocytes, B cells, naïve memory T lymphocyte subtypes. In mixed peripheral blood mononuclear cells (PBMCs) from same individuals, show what extent measures are confounded by both type distributions contaminating platelets....
